Named for citrus grower Arthur Gregory Sr., Lake Gregory Regional Park is maintained by San Bernardino County. The park is popular with families due to its large waterpark, complete with diving platforms, water nozzles, slides, paddle boats, and magnificent beaches. Note that you must be at least 7 years old and 48 inches tall in order to play on the park's inflatable structures. Visitors can head over to the marina to rent a variety of aquatic equipment including stand-up paddleboards and motor boats. Anyone hoping to catch some fish will enjoy Lake Gregory’s abundance of rainbow trout and brown trout. The Cove Café serves delicious gourmet meals, and the Beach Club will be a hit with visitors who seek an exclusive club atmosphere without paying an exorbitant membership fee.
A 2.3-mile trail snakes around the perimeter of Lake Gregory. This accessible hike is a good option for those who want to hike in the San Bernardino Forest without venturing too far from the Regional Park. Keep an eye out for the indigenous wildlife, including chickadees, the southern rubber boa, and especially be on the lookout for the Mojave green rattlesnake (Crotalus scutulatus), considered the most poisonous rattlesnake species. While it is rare to spot them during the day, bobcats, coyotes, raccoons, beavers, grey foxes, and skunks inhabit the area as well.
The 84-acre lake resides in the city of Crestline at an elevation of 4,550 feet, which means that the temperature is significantly cooler than its neighboring towns. This can be a nice respite for visitors who have been hiking around the San Bernardino Forest in 100-degree weather. Popular San Bernardino hikes include Deep Creek Hot Springs, Aztec Falls, and the Upper Deep Creek Canyon to Devil’s Hole. While Gregory Lake does not allow camping, Mesa Campground and Silverwood Lake Group Campground are nearby.
