Lake Gregory had so much more to offer than anticipated. Loved the inflatables, the very fun, relaxing atmosphere and having boat rentals available. We were especially impressed by Dre at the boat rentals. He was very helpful in helping us decide on kayaks or canoes for my 6 y/o non-verbal autistic grandson. We really appreciated his time while getting my grandson in the canoe, while understanding we may have had to change things last minute due to my grandsons sensory issues/fears. Thank you so very much Dre! You made the day even more special for us. read more

I was recently camping in Crestline and I like to come down to Lake Gregory. This time I decided to get out on the water and the first available rental was the Swan boat that you pedal on the lake. It was very easy to rent and the team there is very friendly and helpful. It was $45 for one hour which was perfect. We felt safe and really enjoyed the boat, and the lake and all the views that came with it. I don't know why I didn't try this sooner since I've been coming up here a few years already. I will definitely make this a tradition every time I come up. read more

Rip off honestly $17 per adult to go to their beach / lake? They try to charge you for everything to using their WiFi for 25 min for $5. Small and crowded. Make the drive and Go to a regular beach for free. read more

Such a fun spot! The scenery is beautiful, the activities are all so much fun. We spent the entire day here it was a great value- unlimited trips to the inflatable waterpark and slides. We had kids from 3-13 and every single one enjoyed the day. I would highly recommend this really is a gem of a place! read more

Lake Gregory Regional Park - Hiking Near Me - Crestline, California

We really wanted to like this place and it was hit and miss. Staff were nice and helpful. We reserved a cabana but were missing one chair and were told " well I don't know it probably broke". Well we paid few hundred bucks so maybe find us a chair??? The cabana and chairs were old and uncomfortable. The biggest thing was we paid to use water park stuff. It was so packed and they ran out of life vests. They are required. So then they tried to monitor timing of 30 min in water and coming out. My husband could never get in same time as kids. Long unorganized line. We witnessed multiple fights break out. I'd rather just go to another lake and not deal with all those folks crammed in small place. We rented a boat and that was nice and easy. read more

Lake Gregory Regional Park - Water park. - Hiking Near Me - Crestline, California

We were very disappointed with our experience at Lake Gregory. We purchased the All Access Passes for our four children because the website advertised access to the inflatable water park and water slides. However, after arriving, we found out the water slides were only open from 2:00-4:00 PM. This was not made clear when purchasing our tickets, and there was no price reduction or partial refund despite paying full price for attractions that weren't available most of the day. The lake itself was also disappointing. The water was green and had an unpleasant odor, making it far less inviting than expected. Another frustration was how inconsistent the shade policy was. Staff would not allow us to set up our small, soft pop-up shade for our family, yet larger tents were permitted nearby. The rules didn't seem to be enforced consistently. Overall, for the price we paid, the experience did not live up to expectations. Better communication about attraction hours, consistent enforcement of park policies, cleaner conditions would go a long way toward making Lake Gregory a more family-friendly destination. read more

Went up to Crestline last weekend! It was a lot of fun. I went up with my parents and were we looking at some houses. Drove past the lake several times during our journey lol The lake is so pretty. We stopped at the grocery store and some places along the way. It was kind of on the warm side last weekend. I was hoping for cooler weather. That's okay though. It's always a nice time visiting lake Gregory and Crestline. This is a very family friendly area. Lots to do for fun. The dog park is always a good one to stop at. read more

First time here. Was very well run, nice staff and clean. For 3 and 6 year olds the small portion of the inflatable was best suited for them. Couple downfalls were the water slide didn't open until 2pm and the splash pad/water slide is all the way across the other side of the lake which makes for a very long walk with little ones. read more

We really had the best time! We celebrated my son's birthday there two Saturdays ago! Got two of their cabanas, all access passes for the kids and just had a blast! It's clean, well supervised and felt that everyone there was helpful! We walked up to dominos ordered pizzas to bring in for the group! Also it feels that they have a lot of rules to follow but in my opinion thats one of the part I liked best about here! Makes it enjoyable for all! read more

I am very disappointed with our experience at Lake Gregory Waterpark near Lake Arrowhead. My daughter and my husband were riding one of the large water slides using the provided sliding mats. Unfortunately, the handle on the mat was not securely attached. As they went down the slide, the loose handle caused them to lose control of the mat, and both of them hit their heads twice during the ride. It was very frightening to watch and could have resulted in a much more serious injury. This is a serious safety concern, and I hope the management inspects all of the sliding mats and replaces any that are damaged or defective. Families should be able to enjoy the park without worrying about unsafe equipment. Unfortunately, because of this experience, we were not satisfied with our visit. read more

The lake was slimy. Too much algae. If you have kids between 6 and 12, they may enjoy the water jumpy things but not fun for adults. Probably lots of kids peeing too. Definitely not a place for me. Swampy looking water. Also the water slide is too rough. Lots of young kids and young teens exiting the slide complaining and saying they've had enough. Even 30 year old parents talked about how rough it is. The need to slow it down so it's a more enjoyable ride. Again, slippery algae on the bottom of the slide exit. Gross. If you took those ugly jumpy gyms off the lake, it would be much prettier. I couldn't get outta there fast enough. Waste of money. read more

The family had a great time at Lake Gregory, especially the boys. There were plenty of things to do, such as sliding down the slides, jumper, fishing, renting a boat, and hiking. Although the lake was fairly small, it offered a serene atmosphere. Visitors are allowed to bring their own food, chairs, and umbrellas, but alcohol is not permitted. The lake also has food available for purchase and provides life vests. Restrooms are conveniently located nearby, along with a shower to rinse off. I really enjoyed myself, relaxed, and spent quality time with my family. It was a wonderful experience to just be together. read more

Parents beware. The lake was great, however the organized activities such as the inflatable obstacle course, kayak, and water slide had little to no concentrated supervision or consideration for safety. While it's understandable for youth to have a good summer job as a lifeguard, however as a parent, I would not be comfortable having my child play in the water. Our adult friend almost drowned due to the faulty obstacle inflatable course, and when we notified superiors, we were told that it's an ongoing problem and that there was nothing that could be done. read more

Went to check it out but it's a little lake that offer to public with fees. They also charge parking as well; you can bring your own food and drink, no alcohol. They also have a place selling food. They have a lot of activities but will need to reserve ahead of time. It's a small lake; and I think the cost is the boat rental is quite steep for what it is. read more

Lake Gregory Regional Park - Hiking Near Me - Crestline, California

Oh how I love Lake Gregory . Plenty of things to do here from hiking to fishing or just admiring the water. It is a contact lake in only the certain parts. During the summer, you can swim at the "Beach " part of the lake . But everywhere else is not allowed. There is a trail going around the lake, dogs are allowed but you need to leash them. I have seen dogs run into the water for a bit but they were closely watched .there is a dog park also . Plenty of parking at the lake , make sure you download "Park mobile" app to pay or they have pay stations there. They also have boat rentals there, kayak and aluminum boats. You can take your own vessel there but they cannot have gas motors. Float tubes and wake boards are allowed too! A great lake to fish too, especially during the winter months when they stock trout . Summer, they'll stock catfish . Beautiful lake, come check it out ! Staff here is helpful and very informative. So. Much good to say about this lake, so I don't want to spoil it for you, come by at check it out for yourself ! read more

We came to Lake Gregory for the inflatable water park. It was easy to park and download the park mobile app to pay for parking. We arrived at opening 10am, bought our wristbands and were able to find a shaded spot. The family enjoyed the inflatables and hillside slides. The was a small splash pad area for kids and restrooms around the beach area. There was also a concession stand with food and snacks. Overall, our family had a great experience. read more

Lake Gregory Regional Park - Inflatable water park area - Hiking Near Me - Crestline, California

We visited the beach part of the lake twice over the last two weeks and my kids absolutely love it! We purchased 2 beach passes for the adults and 2 all access for our kids. On our second visit we arrived earlier to secure parking and a shady spot. Just a heads up, beach umbrellas do not do well on the sand because it is really hard to get them to twist. However, there are a few shady spots to set up at. The snack bar has some pretty decent food. My daughter absolutely loved their fried chicken sandwich! The bathrooms were pretty well maintained but the stalls in the women's restroom are a little tight. The staff is friendly and the place is well maintained. There are lifeguards everywhere which makes me feel safe about my children in the water, especially in the inflatables area since it's a little further out and hard to keep a consistent eye on them. The place is clean, fun, beautiful, and overall a great place to visit. The only reason I took one star off is for their beach hours. They close pretty early for the summer (at 5pm). The sun sets a little later in the summer so it would be nice if it stayed open a little longer. Despite this, I will still visit again this summer! read more

Reservations recommended! Staff is friendly and helpful. We rented kayaks, a canoe, and a duffy. The tandem kayaks were newer and enjoyable. The single kayaks were a little older and didn't offer a lot of lower back support. On our first day, it was beautiful and we had a blast. We went back later in the week and it was much windier - made for a slightly less enjoyable day, but still worth it. It's a great and inexpensive way to get out on the water. read more

Here 8/31/25- READ ALL. Parents be alert Cons- No floats allowed in the swim area Swimming is REALLY BORING JUST STANDING IN THE WATER The water is dirty and a bunch of gross slimy vines at the bottom as it gets deeper. The water in the swimming area was limited because there was NASTY slim gunk‍ No Grills or BBQs allowed. No alcohol Pros- Bathrooms. Plenty of space for your canopy. You can bring all you need to set up. A splash pad- I forgot to snap a photo. Sick people here. I seen a brother and sister touching each other like boyfriend 2 of my kids 3/6 had a hypothermia reaction. It was very scary. Shivering cold and sleepiness my child got from playing in the obstacle inflatable. Immediately we got out the water and I sat down for her to dry and get warm in the sun. A life guard assisted me with a Gatorade and towel. Her systems were severe hypothermia while my other child had moderate. Parents please be alert with her kids Parking is best when you download the app. ParkMobile. This place is tooo strict to have fun in the swimming area. Honestly, we will not be back here. This was a one and done for us. Paid to much money for be restricted soo much! read more

This was a blast! Took the whole family, the weather wasn't perfect but we still had a blast! The obstacle course was a ton of fun. Kids enjoyed it! Recommend getting there early as there was a line to get in even before it opened! Everyone was nice and helped people when they fell off. A huge workout, lol thank goodness for the life vest, i was exhausted after each trip to the rafts/obstacle courses. Have fun and get out, this is a great place to go for the day! read more

Our first time here today and overall, we loved it. The little beach side Cafe thing had delicious food that was not too expensive. The lake itself was pretty darn clean. The side of the lake we were on wasnt too crowded either. The waterside was surprisingly super fun as well. Except for the rule of no personal inflatables and the reason being (from lifeguards) "false sense of security" as well as "environmental reasons". I find that excuse kinda weird considering they have a floating PLASTIC/RUBBER playground lol. Other than that small annoyance, no complaints. For the overall price of full access and how close it is to us (phelan) We definitely will still be back hopefully soon read more

Five Stars for the fun inflatable water park they have during the summer! It costs $30/person for an all access pass so you can have fun on all the inflatable water slides and obstacle course and built in water slide. You can also rent a covered cabana that has dynamic pricing. On a Monday in August ours cost $149 and it included 4 long reclining chaises and a table in between. My tip is to split one with another family since it's really the adults who use it and like being in the shade since the kids will be in the water all day! If you dont get a cabana you can just set up right on the sand. I saw some people bring their own beach umbrellas for shade. As an adult I had a blast and was in the water a ton too. Everyone (kids and adults) have to wear a life vest but they provide them for free and it was clean so I wasn't grossed out. There are a few large slides and large inflatable course with multiple slides, ropes, monkey bars, trampoline, etc as well as a smaller kids area located closer to the shore. Parking is via the Park mobile app and is easy to do. They have a grill that serves up yummy food for lunch do you can stay and play all day. We'll be back here next summer too! read more

4 stars Decided to take my dog for a scenic hike and really enjoyed this loop around the lake! I believe it's 2.3 miles(?). Don't quote me on that! But it was really nice because the trail stops by a fenced dog park and an unfenced dog area near the lodge. Dogs are allowed to hike, but they must be leashed. Dogs aren't allowed in the water (not sure why), but that's not an issue for my dog since he hates getting wet. However, I did see one woman breaking the above rules....in her defense, I guess her dogs were extremely well behaved and kept to themselves/didn't bother anyone. Anyways, if you're looking for an easy hike, this is a really nice one to add to your list of hikes. Also, something I didn't advantage of, they have boats for rent and day passes for other forms of water entertainment. read more

Lake Gregory Regional Park - The lake - Hiking Near Me - Crestline, California

This park is the perfect getaway from the city for a weekend. I came with some friends after renting a nearby AirB&B from Friday evening till Sunday at noon. We got here early (like 10am) and we had rented a motorized boat well in advance. If you're going to skip the water park part, like we did, and you already paid for your boat reservation, you can just skip paying at the gate (you explain to them that you're not going to the Waterpark part of the park) and skip getting a wristband, since it's not needed for the boat ride part. The lake itself is so peaceful, there are people doing all sorts of activities, like kayak, rowboat, and even paddleboarding. The nearby town (Crestline) is like a piece of rural North Carolina, in California, so it definitely qualifies as an interesting experience. read more

This review is for the lake and its surroundings. We visited in November and it was picturesque with the Fall leaf colors. There is an easy walking loop around the perimeter of the lake (around 2 miles) which allows for beautiful photos along the trail. There are two main parking lots which you pay through your phone. The fees were reasonable ($2.35 for one hours and $3.35 for 2 hours). There are a few parking spots on the street as well. I love how quiet and peaceful it was. Lake Gregory is not as busy as Lake Arrowhead so I didn't have to deal with the crowds and traffic. There is a boat house where you can rent Duffy boats, kayak, fishing equipment, paddle boats, etc. There is a fenced in dog park. Highly recommend stopping by if you're in the area! read more

Rented a summer lake house in Crestline and bought tickets for the inflatable water park at Lake Gregory. I was so happy to see it was not overly packed like most places can be. It truly is a beautiful lake, and we had so much fun on the obstacle course! The workers are so kind and patient (feels like almost everyone in Crestline is) and the lake was beautiful. Sure, there were a couple dead fish in the water... but what can you expect we are swimming and jumping into their habitat. The ticket price was amazing! 30 dollar adult price for an all day pass? This was definitely a perfect summer idea and recommend it to anyone else before summer ends. read more
