Friendly reminders before coming to Lake Gregory: For the safety of all our guests, no glass, alcohol, or personal BBQs allowed anywhere around or inside the lake.

The Waterpark

Splash the day away on Lake Gregory’s Waterpark. This huge, inflated, water-play structure floats on 13,755 square feet of the lake’s Swim Cove and offers wet fun for all ages. It has slides, swings, jumps, diving platforms, and much more. The Waterpark is available to anyone at least 48″ in height or taller. The Waterpark also has winding water-slides that whisk thrill seekers down a winding hill to the lake’s edge. Race a friend side-by-side to see who wins! Buy a Waterpark Season Pass as an individual or for a family of four; it’ll be a summer of fun for everyone!

Note: For safety and the enjoyment of guests, the water park has maximum capacities. Once we reach the guest maximum, we are required to rotate guests for twenty to thirty minute increments. Like any popular ride or waterpark  during busy days, you may have a short wait in line. We thank you in advance for your patience during these periods.

Water Play Park

Our Zero-depth Splash Area allows children of all ages to socialize, splash and keep cool during summer.  The colorful variety of water-spraying nozzles in the shapes of flowers and other objects provides a safe and engaging way for little kids to enjoy the water.

Due to the ongoing beautification project taking place here at Lake Gregory, our water levels have been significantly lowered while our dam is being renovated.  The zero-depth water area requires a minimum depth of water to initiate the water pumps which allow it to function.  While our water level is low we are unable to have this area open.  We regret any inconvenience this may cause our guests and we look forward with optimism to them being functional once again in our 2019 swim season.

Swimming & Beach

Sunshine, surrounding pine-forested mountains, warm days, fun water slides and water play structures, lifeguards, lots of on-water pedal and paddle boats, cool and clean lake water, delicious snacks and a sandy beach… Lake Gregory has them all. Lake Gregory is the mountain lake in Southern California for sunbathing, making sand castles, water play, or just a romantic stroll beside the lake. Lake Gregory is located at Crestline in the San Bernardino Mountain’s historic and scenic Valley of the Moon.

Lake Gregory has one of the cleanest lakes in the San Bernardino Mountains. Water tests are done weekly during the active swimming months and monthly for all other times.

Note: Dogs are allowed on the trails and the dog park. For all of our guest’s safety, only certified service animals are allowed in the beach areas. Under the ADA, a service animal is defined as a dog that has been individually trained to do work or perform tasks for an individual with a disability.  The task(s) performed by the dog must be directly related to the person’s disability. Emotional/companion “Service” animals are not permitted on the beach and not recognized by the ADA as service animals.

Float A Boat

At Lake Gregory, you don’t need to own a boat to get out on the water. Lake Gregory has rental belly boards, aqua cycles, pedal boats, kayaks, stand-up paddle boards, row boats and electric motor boats.
