There aren't many cars on the roads between 10am-12noon, so it's a breeze riding a bike around and resting for a hydration stop here. Tiny public parking lot onsite off Milpitas Blvd. Hidden Lake neighborhood have peaceful homes and nice walking paths to get a glimpse of the small lake sometimes filled with ducks. You can easily walk up and down stairways or bike around the neighborhood area near the homes. Yes, there are picnic tables and families do stop to enjoy small gatherings. Hidden Lake Park is not far from retailers/restaurants/grocery stores/fast foods/etc. Convenient. Not many visitors on weekdays. It's always clean when I stop by seasonally for a morning biking routine. The clouds look great outside today, so it wasn't too hot under the sunshine. Overall, good place to chill before continuing onto Milpitas Blvd. where there's bike friendly streets now. Easy to follow the paths and navigate around town.

***the lake itself is part of a community called HIDDEN LAKE as well***…read more OVERALL: Meh. Wouldn't go out of my way to drive here to walk; therefore the 4 stars rating. Due to being part of a community, there are a ton of guest parking (especially near the gates to this park) BUT if you keep driving, the parking lot for this "park" is on the outside (you turn in with the sign "HIDDEN PARK LAKE" in green lettering/tanish brown background and there are a few spots for you to pick from). Two stairways up to other flat cement ground trails. Very quarry lake vibes but not much water. Lake itself is a smaller circular flat cement ground leveled trail. Regarding up the stairs: One way does end up at another park whereas the other way just ends up in another neighborhood/main road. Lack of shade. Lots of ducks. There's few places to sit. Few trash bins. No visible toilets.

The short trail in the park continues to surprise me! Every visit is so different. I decided to go…read moreon a weekday morning and experienced a very relaxing walk with good views.

One side of the trail has plenty of trees, while the other side is more exposed to the sun. It wasn't overly crowded, even on a weekend. I suspect that's because parking costs $6 and there is no street parking available. Unlike many parks where you can park nearby and walk in for free. I visited on a summer day when temperatures were around 90°F. It was quite hot, with little to no breeze. We stayed until sunset, the lake reflected the evening colors, it's beautiful.

Incredible hike! However go early because parking is sort of difficult to find later in the day…read more The best time I find to go is early morning since it's cooler and the parking will be easier to find. Around 7-9 am. Super clear trails, beautiful plants and livestock that occasionally walk by. Fantastic hike and I will continue referring majority of my friends here!

There is a $6 entry fee, and plenty of parking in multiple spots, and closes when the sun goes down. The fish limit is 5 fish per person. There is a lot of fishing space, some on muddy terrain, and some over rocks and grass. People were paragliding and hang gliding on the beautiful lush green hills next in the back. If the only thing you can do is walk, then it's a great one filled with much wildlife like cute hawks and birds; not too short not too long with plenty of shade if you stick near the lake with dispersed picnic tables, and that wonderful view. Cell phone service here sucks. They have barbecue pits and fish cleaning stations. Definitely a hidden bay area gem.

The Sandy Wool Group Area includes a giant gazebo with a new-looking roof providing shade, a large BBQ grill in the center, and plenty of picnic tables surrounding the grill - plenty of space for our group of 30+ to spread out. Very peaceful area, even on a weekend. + Plenty of parking available ($6 per car) + Clean restroom, even stocked with pads and tampons + Dogs allowed Note: none of us had any cell phone service there, so make sure to coordinate beforehand and enjoy the present moment! I'll have to come back another time to walk around more and maybe try my hand at catching some fish in the lake.

Honestly? Alviso Marina County Park isn't really bad after all. The first time I went was a few…read moreyears ago when I visited after a rainy day and that the trails are very muddy. Rarely any people came here. However from this visit, I came in the right time. It was sunny during the day and many people came here for a reason. Keep in mind that it's not a regional park but rather a wetland. When you look at the water, it's colored slightly red from its edges. Also, the trails are light since there is no elevation here. It's really good for jogging and biking. I've seen people do that here. The trails are very long which is why I selected a stop so I can turn back to where I started. Ideally, you want to come here in earlier in the morning so that you can hike longer and end sometime in the early afternoon. It was hot outside and I prefer not to hike longer. Basically, I powered walk from halfway. It's not necessary to bring hiking shoes due to light trails but you should use them if it's muddy. Perhaps, I should come here way earlier so that I can maybe hike longer.

We did the Canyon View to Little Yosemite trail and I recommend downloading the map ahead of time as there was no service in the park. Trail was well maintained and the views of the green hills were very pretty! Came across some very friendly cows as well. Just be aware if you are going during the summer that there are no trees so limited shade. We did the trail clockwise, which starts off with a somewhat sharp incline and finishes with a gradual decline. I would recommend this direction so that you tackle the difficult portion first and then recover at the end with the descent. We also did part of the McCorkle trail, which was pretty tiring, so we decided to skip Little Yosemite using Cerro Este Road - appreciated how there are shortcuts available. Canyon View trail was not too busy, and we ran into more people (+ dogs/kids) on the Camp Ohlone Road heading toward Little Yosemite. Overall, it was a great, moderate hike and I would definitely come back to see Little Yosemite next time!

A group of 5 of us decided to do Rose Peak Trail from Sunol. This is a brutal 17.8, 9.5-10 hour…read morehike and up to 20 miles depending if you start from the visitor center. Started late at 9 am with few breaks and got to 3k elevation and still didn't reach the peak at 1:30 pm. A lot of hills and valleys with climbing/walking for 4.5 hours straight. Going back wasn't as easy since there's still some hills to pass. All in all, we did 18 miles for 8.5 hours of hiking. At least know what to expect for next year. The trail markers are numbered decently with not all marked. Bring a map and plenty of water! 2.5-5 liters is recommended by people who finished. Start right at 8 am. Saw 3 tarantulas and there are rattlers/mountain lions from the signs. Definitely one of the hardest hikes in the bay! Not much to see on the trail or views.

Went on early foggy morning hike. Hiked to Inspiration Point and then to Eagle Rock…read more It was a cold morning but much more enjoyable than the Summer heat. The trail to Inspiration Point had gradual climb that's not too long. Lush greens all around. Encountered a group of deer. Ground was not too soft so it was not too slippery or difficult that I felt comfortable with just trail runners on. Restroom at the start of the trail but none for at least another 5 miles. There were buildings that looked like restroom but were closed. Multiple parking lots at the main entrance to a few more inside the park. The trail to Eagle Rock had longer climb but not too bad. Nice view all around.

Rock the Block Alum…read moreRock Park is what many, myself included, consider to be *the* crown jewel of CSJ parks, and it's easy to see why. From the vast 730-acres of green space includes thirteen miles of trails that run the gamet of flat sojourns, to steep hikes to Eagle Rock. It's also California's oldest Muni park (1872) but has always served as land since 1777 when the Pueblo was established. The Good: *Variety of trails, as mentioned above, and they're mostly shaded. *Lots of history here as there's remnants of an old train trestle that used to run visitors up to a health spa of sorts. There's still remnants of the spa as you can see--and smell thanks to the sulfur springs. *Trails also connect to adjoining Sierra Vista OSP, and is part of the Bay Area Ridge Trail. *Sand volleyball courts *Playground *Reservable and non-reservable picnic tables *Restrooms *Six miles of Horse trails *Three miles of Bikes trails *Home to the YSi (Youth Science Institute), which I highly recommend to parents. They have a bunch of summer camps that are great ways to get kids to love nature. The Meh: *No dogs allowed *Lots of poison oak *Parking costs $6 *Cell service is spotty, at best. The Ugly: *Budget cuts, budget cuts, budget cuts... Thanks to the lack of caring by our leaders for our parks, this place is not as great as it once was. As there's several entrances that have been closed off for nearly thirty years! *I can't believe I haven't written a review for this place yet. As the (unofficial) Mr San José I find it very shameful and shall self-flagellate immediately. Conclusion: Not as great as it used to be, but still pretty damn amazing.
