One of the most interesting hikes I've been on in the South Bay! We took a random hike on a Sunday afternoon, and it actually wasn't too crowded in the lot or on the trail. There's a number of different types of trails you can go on. It fascinated me how it alternated between a regular trail, to smoother hills, to a bit of a rocky climb. I would definitely recommend stopping by, especially for the gorgeous views! read more

Have long eyed the Castle Rock State Park and glad we finally went! The park charges a nominal parking fee ($10 at time of writing); the parking fee is waived if you have one of the supported passes. Check their site for more info: https://www.parks.ca.gov/?page_id=538# We really enjoyed our hike here. The space is beautiful, and the trails are well-maintained. The trailhead had plenty restrooms as well. We made it up to Goat Rock Lookout, back down, then detour to the waterfall. It took ~1.5 hours in total, which was perfect for a end-of-day hike before the park closes at sunset. The view up at Goat Rock Lookout was breathtaking! read more

If you're looking for another place that has breathtaking views surrounding the whole Santa Cruz Mountains (but don't want to go all the way to Portola Valley), Castle Rock State Park is the place for you. This place is usually my go to when the weather is just perfect and you want good views of the mountains viewing the Monterey Bay and the Santa Clara Valley. In addition, the park is even open during the cold winter season, where it occasionally will snow (because of how high the elevation is, the main base is situated at about 3,200 feet above sea level). This place has been my go-to park for hiking for a while, because of its terrain. At the same time, it's also been because of how much snow they get when cold fronts come into effect. They are also open year-round, so definitely swing by this state park when you do get the chance to! It's a decision you'll never regret. read more

Easy hikes, amazing views and unofficial drive for sports cars and bikes? I drove from West to East though Castle Rock SP and did a couple of quick hikes on my way to another destination. It was my first time visiting CRSP. The drive and the views from these Santa Cruz mountains after short hikes were magnificent! This SP was scenic and I enjoyed it except for a couple of unusual experiences. A rare turn off at a park for me was too many rock climbers hogging big boulders obstructing access to hikers (or anyone else) to reach the top of those boulders / peaks. The rocks themselves appeared to be sandstone and not granite. Go figure. Another surprising thing at this scenic park was many, many, many sports cars and bikes RaCiNg on the Drive. It was pretty aggressive and not something one would expect at a SP... much more so compared to the Dragon and Cherohala. Nothing mentioned about speedsters but maybe it's local thing? There wasn't a visitor center or facilities I saw. Parking was tight at a couple of trailheads. But at the paved lots at lower elevations were practically empty. Glad I visited CRSP but likely wouldn't repeat. read more

Great hiking trails with unique rock formations, waterfalls, over looks, grottos and goat rock for climbers.

This park is so beautiful! They have very many trail options depending on your trail levels. It very clean and well kept. I also think it's cool how they have areas where you can go mountain climbing and even a rock that they actually teach rock climbing. The pictures taken with the amazing views was on goat rock. It's a pretty easy climb but they also have a rope that you can use to help you get up.one day I'll do their mountain to coast hike but it's a long one and I hear that parts of it were closed down from some of the fires that happened a few years back. In my opinion this is one of my favorite hiking spots! It doesn't matter if you need an easy, moderate, or if you're up for the challenge and choose a hard hike. They have something for everyone and you'll get that peaceful and beautiful experience no matter the trail you choose. The only bad thing I can say about this park is the parking. They closed the overflow parking area, which we usually would park at, that kinda sucked. So my suggestion is to get there early because parking can be a challenge at times. read more

This was a really neat surprise, an unplanned stop at the top of the mountain. It was a very foggy day, and it made this mossy redwood forest have a ton of mystique while hiking through it. Trails were clearly marked and the difficulty was easy to understand. Park Rangers at the pay station were very helpful, suggesting a great route for a moderate 2 hour round-trip hike. Castle Rock fall was a neat view, the waterfall wasn't anything huge, but watching it cascade down a steep drop was interesting. Apparently on a less foggy day, the view from here is also outstanding. When I went, the fog was so dense, you could barely see beyond 50 feet or so. That did make it a pretty sparse day at the park, so I had a quiet hike without seeing many other people. The actual Castle Rock is pretty darn cool looking, and aptly named! Most any visitor can access this easily from the parking lot, no matter their fitness level. I would definitely come back when in SF next time on a clearer day to catch some of the views I missed! read more

How spoiled we are to be surrounded by so many beautiful parks. I visited Castle Rock on Saturday around 10am. There was plenty of parking in the lot, which was $10. There's a few spots on the road, which are free but hard to get. There are maps available and we decided on the 2.5 mile one, I believe it was called the Saratoga loop? The views were breathtaking. Plenty of trees and yes, lots of giant rocks. Toward the middle of the hike there were huge boulders that we climbed and were able to really take in the view. Along the trail there were two separate groups of rock climbers, this was cool to see. When we were done with this hike we found another one on the other side of the road called the Skyline trail. This was also beautiful and had fewer people. It was only a mile long but more challenging than the one we had just finished, due to the incline. Cell phone coverage isn't great so make sure you download a map of the area beforehand. read more

I've heard so much about this hiking spot and it didn't disappoint at all. Reading through the reviews parking was what I was worried about as they stated to come real early. Got here at 10am on Saturday and was surprised there was a lot of parking. If you park inside the State Park it's $10, but there's free parking that's about a 5 minute walk on the road. One of most organized parks I've been too lol. Signs everywhere and the maps are detailed on distance for each trail. The views are and trails are amazing. Well worth the visit. Would highly recommend this trail. read more

Beautiful spot to visit if you like hiking! The view is great, but parking is limited. Make sure to come when it's not too bus. There are spots to boulder and there's a lot to explore read more

I have come here a handful of times over the past handful of years. It is a really nice place to hike, and looking at the giant boulders in the park too, I can see why it is a popular bouldering spot. During my most recent visit, it was very foggy in the mountains, but that gave the park a very atmospheric feel. There used to be this gravel parking lot that was free, but lately it's been closed and so you have to go to the paved parking lot nearby and pay $10 for parking. I think it is worth it though if you plan to hike for a bit - plus there are restrooms and picnic tables there. This place is quite the g em in the South Bay area and I would definitely recommend hiking here ! read more

Arrived to the trailhead by 8:30 on Saturday after Thanksgiving with friends.  Weather was beautiful, cold but no wind.  As popular as this trail is, the $10 parking lot was sparsely filled, later it filled up as we were leaving at 11ish.  The huge parking lot and restrooms were quite classy. In 3 hours time, we were able to visit everything we had planned - climbed on Goat Rock, basked at the vast views on a rock along Saratoga Gap Trail, saw the waterfall which was just trickling, and visited the famous and crowded Castle Rock.  This is a great hiking destination because it is close to town, great views, and fun opportunities to scamper on rocks. read more

The way to castle rock is up the side of a mountain so choose your routes well. Fortunately for me, I had some guidance and was told to take route 9 which is 1 lane but wider lanes than if I were to take route 17 which has narrower lanes and faster drivers. Not to say that route 9 didn't have fast and furious drivers hellbent on meeting their maker early. I had to pull over once each way to let people pass me since this is my first time driving this round. I was at speed but apparently too slow for those folks. Anyhow, park rangers are nice here and bathroom is clean! Rock climbing here is fun. read more

Listen, if you haven't been to Castle Rock State Park, you haven't lived. This place makes the Garden of Eden look like a strip mall parking lot. The air here isn't just fresh -- it sings. I swear I inhaled once and gained +2 stamina and +5 charisma. The cliffs shimmer with mysterious power (probably quartz, possibly wizard residue). At sunset, the rocks glow golden, and if you listen closely, you can hear the faint hum of ancient elves arguing about real estate. Bring a snack; stay for the magic. The Trails: Hike the Ridge Trail if you want views that will make your phone camera cry. Seriously, you'll take one photo and your phone will whisper, "That's enough, I can't compete." Beware, though: past mile 3, sightings of gentle forest monsters increase by 47%. They're mostly chill, but one might offer unsolicited advice about your hiking form. The Waterfalls: During the rainy season, the waterfalls look like liquid diamonds being poured by a slightly clumsy goddess. A ranger once told me if you whisper your Wi-Fi password near them, you can summon free cell service for 30 seconds. It's never worked for me, but I respect the lore. ‍ The Locals (Flora & Fauna): The squirrels here have MBA-level negotiation skills. Bring snacks, or lose your granola bar empire. A crow once took my hat and returned it with a feather "for protection." I haven't been struck by lightning since. Coincidence? I think not. Somewhere deep in the forest, there's said to be a retired wizard who trades hiking tips for riddles. He's allergic to flip-flops, so wear boots. read more

Having back here for awhile, the park is still clean and this time WiFi is much not working. Parking is $10 for one car and entrance is easy especially there is trail arrow showing which direction and distances. I came here on Saturday morning and it was empty, but parking seem full. read more

I recently visited Castle Rock Regional Recreation Area, often called Castle Rock Park by locals, and I'm giving its picnic area a solid 4-star rating. Nestled in a scenic canyon along Pine Creek within the Diablo Foothills Regional Park, this spot offers a delightful escape with a mix of natural beauty and practical amenities that make it a great choice for a picnic outing. The picnic area itself is well-equipped and thoughtfully designed. There are eight reservable sites, with capacities ranging from 50 to 100 people, which makes it ideal for both small family gatherings and larger group events. I appreciated the ADA accessibility--wheelchair-friendly pathways, accessible picnic tables, restrooms, and changing rooms ensure everyone can enjoy the space comfortably. The sites are partially shaded, offering a nice balance of sun and cover, and there are even drinking fountains and a swimming pool nearby for those hot summer days. The quarter-mile walk from the parking lot to the picnic sites is manageable, though I'd recommend bringing a wagon for heavier items as there's no shuttle service. The setup felt practical yet serene, with the surrounding canyon and views toward Mt. Diablo adding a peaceful backdrop to our meal. What really stood out was the access to nature right beyond the picnic area. After eating, we ventured onto the trails that wind up the canyon, and within a mile, it felt like we were deep in the countryside despite being on the edge of Walnut Creek. The trails connect to over 18,000 acres of public lands, including Mt. Diablo State Park, which is perfect for a post-picnic hike. The park also has amenities like basketball courts, horseshoe pits, and a volleyball court, which added some fun for the kids in our group. One thing to note--parking can be tight, especially in summer, so arriving early is a good idea. Also, while dogs are allowed in the park section, they're not permitted on the rangeland trails, which was a slight bummer for our pup. Overall, Castle Rock Park's picnic area offers a fantastic blend of convenience and natural charm. It's not perfect--public transit access is limited, and the walk from parking might be a hassle for some--but the setting and facilities make it a spot I'd happily return to for a relaxing day out. read more

This park is one of the best outdoor bouldering spots around San Jose and hosts some incredible hikes. I always hike after it rains because the skies shine brighter. The park has sandstone formations as you can see in my videos. They make some cool "caves" to explore and get some shade in. I recommend coming here! There is paid parking and free parking if you're willing to walk a bit further to get to trailheads. read more

Cool short hike to Goat Rock, it's about 1 mile up. You can make the loop longer by just keep going on the Ridge Trail. We made the loop and it came out to about almost 5 miles. There's a lot of shade on the trail, so even if it's hot in the city, it's about 10 degree cooler up there. Nice trees and scenery. On a clear day you can see the ocean. Good short hike. read more

When I think of rock climbing, I think of adventurers attached to ropes, climbing a vertical rock wall. Well, there's some of that going on here, including near the waterfall, where hikers can take a break and enjoy the views while observing climbers nearby. But I didn't realize that hiking the mountain would involve clambering over endless rocks and boulders along the trail, lots of steps to climb, uneven pathways, and steep gradients. I actually freaked out when we had to climb through rugged and narrow passageways, requiring balancing skills, along the edge of the cliff (if I knew what I was signing up for, I would have declined, especially with spotty cell signal if I needed to call for help). But the views of the Santa Cruz Mountains and beyond were amazing.... which leads me to what I loved about the setting, despite my slight nervousness at scarier parts and the physical exertion of hiking at this park. Plenty of shaded trails on rock and dirt pathways, venturing through a forest of trees, as well as tons of greenery (including poison oak, beware), and crossing bridges over the creek along the Saratoga Gap Trail... Trekking to and through Goat Rock, admiring the magnificent and holey rock formations and cave-like structures, like at Dan Seldow's Fraggle Rock Grove, taking in spectacular views at Emily Smith Observation Point... More rock climbing to get to the actual castle rock (it's like a treehouse except it's a giant rock you can climb, instead of a tree, and of course with more holes and caves). There are a lot of similar giant oddly-shaped boulders in the vicinity along the Castle Rock trail, with groups of hikers and campers climbing or picnicking around the structures, but this massive rock formation is larger and clearly labeled, and there's a small restroom nearby. The only downside to Castle Rock Park, besides the risk of falling to your death, is the annoying flies and gnats on a hot day. Otherwise, this was definitely a beautiful and unique hiking experience (and we didn't even do the most challenging trails at the park, which could possibly be more interesting). Also, parking is plentiful, whether at the $10 lot or on the side of the road. read more

Good place for hiking for South Bay Area. Plenty of parking, restrooms, and places to have a dinner or lunch

We started coming to Castle Rock when I first moved to San Jose-- wild and child-free it became one of our go to hiking trail(s) in the South Bay. Six years later, we're still wild (or at least that's what I tell myself) but now with a child, and still come here with our almost two-year old who is not quite ready to hike on his own but enjoys every moment in the hiking carrier. The Castle Rock Loop is really good if you have small kids and want to take them on an adventure. You'll come across many rock climbers and the formations are beautiful. I'd say this loop is doable by 3-4 year olds, There's an incline so just have to be careful. We did the Castle Rock Falls Trail this past week, which is a bit longer. You go to Castlerock Falls and come back. There's a deck from which you can look down at the falls (it's very steep). Some parts of the trail proved just a little tough and required maneuvering; husband is used to the carrier so we were okay. If the child is walking then just have to be extra careful, some steep places. Both of these trails are shaded so layer up if you're going during winter. The longer trails are a mix with beautiful panoramic views. There are two paid parking lots and if you come early you can park for free outside. The smaller parking lot only takes cash. Rangers are also there to help you decide on trails. read more

One of my favorite hikes in the Bay Area! A must hike place to go and try. It's considered a moderate loop hike with some rock climbing involved. I loved it. There are also rock climbing for advance hikers here but you bring your own equipment. Fun watching them! Only 5 miles but a heavily traffic trail as many love it here as well. Nice mountain views and half the trail is shaded. There is plenty of paid parking here but if you don't want to pay, there are plenty of outside parking as well. It's best to go early morning to beat the heat and crowd especially in the weekend. A definite recommended trail for many first time hikers or regular hiker. A good sweat to get your heart pumping!

Castle Rock State Park, nestled in the Santa Cruz Mountains, is absolutely beautiful. I hiked the Saratoga Trail partially and Castle Rock Trail, which form a loop. The Saratoga Trail led to a lovely waterfall and had stunning views of the mountains throughout. Some parts of the hike are easy, while others can be more challenging--especially the Ridge Trail above Saratoga, which I only completed a bit of it due to its steeper climb. The rock formations on the Castle Rock Trail were especially unique and worth seeing. I went on a weekday (Wednesday) and was able to park outside for free since the lot gate was closed--it was quiet and peaceful. On weekends, it may be busier with a $10 fee. The park is huge with many trails left to explore. While I personally prefer the mountain views at Russian Ridge, Castle Rock's waterfall and rock features make it a place I'd definitely recommend. Note: no dogs allowed. read more

It's been a minute since I've hiked the trails at Castle Rock actually over 20 minutes I'd you catch my drift. I use to frequent Castle rock about once a month, boy how it's changed, there is a brand new parking lot right near the 1st small one "which was packed full of cars" admission for parking $10!! The park it's self is beautiful with miles of trails, I walked for about 2 hours, you can do some rope climbing on rocks at the park as well. I would recommend bringing a pair of walking sticks as parts of the trail can be. Treacherous with slick rocks. read more

Great trail! With lots of climbing up and down. We stopped at the rock because going around seemed very sketchy, but I guess if you walk around it it's a loop. Drive up is a solid 30 minutes. Gets very hot but there is lots of shade. Overall hike in the loop takes 1hr - 1.3hours. read more

A very fun & rewarding hike. Gorgeous views that make climbing the rocks so worth it. This hike has a little bit of everything in terms of hiking--maneuvering over rocks, stomping on dirt paths, rock climbing, & more. The sound of the waterfall streams are so relaxing and the views are breathtaking. I wish I packed lunch and had a picnic on a giant rock...next time :). Some incline, but not too much. The hike itself gives you a challenge because of all the obstacles. There are a good amount of trails with little side trails to explore. Definitely a place to return to more than once. We did the castle rock falls and used the inter connector trail to reach the goat rock trail, which looped us back to the parking lot. It was the perfect 2.5hr ish hike (including our stops). The drive up is a bit windy. New parking lot is spacious may get busy during the weekends. For social distancing they marked the trails as one way to prevent face to face passing. read more

Castle Rock State Park I've visited twice, enjoying the new Kirkland visitor center with more parking, though it can still fill up. The park offers clean restrooms, helpful rangers, maps, and picnic areas. While famous for rock climbing, it also has great hiking trails. My visits were in the fall, a dry but beautiful season. A nice loop starts at the Kirkland staging area, follows the Castle Rock trail past unique sandstone formations and trickling falls, and continues on the Saratoga Gap trail with stunning views of the Santa Cruz mountains. Sturdy shoes are recommended for the rocky paths. The loop ends on the forested Ridge trail, which provides a shaded, peaceful walk back to Goat Rock and the parking area. The trails aren't very steep but require good footing, water, and stamina. Castle Rock is a great spot for any nature lover or adventurer, and the new amenities make it even better. read more

This is probably one of my favorite hikes in the Bay Area. This is a pretty easy hike and super beautiful! The view is amazing here and there's plenty of shade. I definitely recommend going in the morning when there aren't too many people. There are two parking lots - the main one & overflow. In addition, there's street parking (free btw). Remember to bring bug spray bc there are bugs! Also, I recommend the road through downtown Saratoga to get here. I took road from 17 and hated it as there are some areas where it got too narrow. read more

I went on a Monday which I believe was a holiday for most so there wasn't anyone at the toll booth. I believe there usually is a parking fee but I'm not too sure as I didn't see any signs about it. Parking is easy and accessible. There are a few options along the road. I parked in the Alum Rock parking area. On the right side is a creek and a trail you can follow. All the trails are fairly easy and the views are beautiful as well. It's a great place to take the family or if you're more of a beginner hiker read more

Castle Rock features some of the most unique rock formations that I've ever seen in a California State Park. In addition to the rock formations, Castle Rock is filled with tons of versatile hiking trails, a plethora of different plant species, campsites, rampant wildlife, and even a waterfall. And those views! I can't forget about those gorgeous views of the Santa Cruz Mountains. Should you embark on a hike through the mountains, be prepared for your eyes to be met with rolling green hills and beautiful blue skies (weather permitting). Right from the gate, I have to mention how limited the parking situation is. You need to get here at the crack of dawn to secure a spot in one of the two parking lots that sit right in front of the entrance. Their main parking lot has about maybe 30 spots or so, and the parking lot across the street has about an additional 40 spots. This is a very busy park. VERY busy. Especially on the weekends. No parking is allowed on the side of the road. Chances are, you may not get to park in either lot. The alternative: Park at one of the nearby Sanborn County Park lots and hike your way over. I parked about 1.5 miles down the road at the Summit Rock parking lot and hiked the Skyline Trail which connects directly to Castle Rock State Park. It added an extra 3 miles to my 6 mile hike through Castle Rock, but it was convenient considering the situation. If you don't mind the extra trek, I'd recommend it. Otherwise, get to the park before 8 am and make sure you have $10 cash for the parking fee. So now that I've gotten that out of the way, let's talk about the actual park. This park really has a great mix of everything. Most of the trails are shaded so you won't have to worry about too much sun exposure. Hiking trails range from easy to difficult, and there's a trail map near the entrance. There's no visitor center here, so I'd recommend studying a map or using the alltrails app to map out your hike. We took the Saratoga Gap loop to the Ridge Trail which made for a moderate 6 mile hike. The hike was filled with various different terrains ranging from flat and paved to steep and narrow through the ridges. If you're afraid of heights, I'd avoid the Ridge Trail. The views are incredible, but there are some parts where you're literally on the edge of the ridge with no barriers and only the rock behind you to hold onto. There's this one gnarly section where you have to hold onto a thin ass rope to get over the rock. Kind of scary, but also a great adrenaline rush (picture worthy too). If you've ever hiked Mount Diablo or the Diablo Foothills/Castle Rock Regional Park in CoCo County, the rock formations are quite similar. The major differences really come down to the size and the location. Castle Rock has some really huge rocks with the craziest looking formations! I saw so many kids crawling into the rocks with human sized holes in them. Gotta love nature! What I also really loved about this park was how green it is. Often times when I've gone to a park that features rock formations, the park isn't as green and doesn't have as many trees or shady spots. But, Castle Rock is the perfect culmination of the two. Tall beautiful trees line the trails alongside vibrant ferns and huckleberries. A botanist could have a lot of fun here. Castle Rock Falls is also a neat sight to see! It wasn't flourishing with water when we went, but I always find something so enchanting about any type of waterfall. We didn't camp here but we did pass by a campsite or two during our hike. Although the trails are mostly shaded, you should still bring plenty of water for the inclines. And don't forget your bug spray! The bugs weren't too crazy but they were out there. This park is really gorgeous and the hike was fun and challenging. I would definitely come back to explore more of the trails and rock formations. read more
