Jellystone Park™ Keystone Lake

We had a beautiful campsite, right on the lake. The only problem was all the sand spurs. We had great difficulty trying to walk our dog.

Hidden gem. This was our first visit. We had a good time. The staff was very nice and the water park was very nice and clean.

It's a great place to take the kids! They thoroughly enjoyed it! We wanted to camp-out the water levels were too high so the lake was closed. There are plenty of tables with umbrellas for shade, lots of seating, and even have cabanas for an additional cost. We will definitely return!

We used to enjoy coming here, but this year the price increased yet again. $50 for just me and my 7 year old to go (Because 5 and up are considered adults ) and every time we went it was SO crowded you couldn’t even swim. When we tried getting in the pool my daughter and i were both kicked in the face by some kid attempting to dive lol that crowded ! the water was cloudy and all i could think about was all the pee that was prob in the pool . So we ended up leaving after an hour both times.

We stayed in a rented RV here Mon-Friday. We have decided it will now have to be a yearly tradition we loved it so much. My son is 11 and enjoyed all the park has to offer. The basketball court across from our campsite was an added perk. We all played on the inflatable obstacle course and had so many laughs and so much fun watching each other fall off. We did learn water shoes with some grip on the bottom are a game changer for the adults who get tired of slipping off. The slides were fun and the pool area was nice. The owners and staff are very kind. We locked ourselves out of the RV and the staff or owner, not sure which, came to see if he had a spare key to help us out. When that didn't work he told us about a place in town to try and they came out with a spare key and got us unlocked. The lake is beautiful and not at all busy during the week. We had a whole island to ourselves and plenty of room to pull kids tubing without any other boats coming around us. Definitely recommend!
