Get to Know Lake Gregory in Crestline, CA

Lake Gregory A 2184

I had never even heard of Lake Gregory in California’s San Bernardino Mountains until a couple months ago. But now the secret is out! Bustling with fun lake activities for families, it’s a perfect summer retreat to the mountains as it’s less than two hours from most major SoCal cities. Lake Gregory is located in the small mountain town of Crestline—yes, that sign you see on your way to Big Bear or Lake Arrowhead (which is 10 miles north).


Play - One of Lake Gregory’s highlights is Rim of the World Waterpark, a ginormous inflated structure that floats on the lake, featuring slides, swings, diving platforms and more. The waterpark is for ages 7 & up who are 48” or taller. Teens and adults love it, too! Day or annual passes available. The Rim of the World Waterpark and swim beach are open Memorial Day weekend through Labor Day weekend (weekends only until mid-June, then open daily).

Swim - One quarter of the lake is dedicated to swimming only and has a “swim beach.”

Ride - Aqua cycles, pedal boats, kayaks, paddleboards, motorboats and rowboats are available for rent on other side of lake.

Fish – The lake is stocked with brown and rainbow trout. There are free fishing clinics for all ages, plus kids ages 4 & younger fish for free.

Hike – There is a 2.7-mile walking path around the lake, plus other well-kept walking paths in the area. Heart Rock/Seeley Creek Trail is popular for families—hikers will find a heart-shaped hole next to a waterfall at the end!

Grow – Don’t miss the free “Fit Kids” program (third Saturdays during the summer) for ages 5-12. It’s health and fitness related, but the goal is to encourage kids to love and appreciate nature.

Other summer highlights include an annual Fourth of July barbecue and fireworks show over Lake Gregory, and Friday night fun featuring concerts, a farmers market and food vendors.
