Lake Gregory is conveniently located less than two hours' drive from many major Southern California cities, making it an accessible mountain escape for a day trip or a weekend getaway.
The 2.7-mile loop trail around Lake Gregory is popular and can be busy, especially on weekends. For a potentially less crowded and more adventurous experience, consider exploring nearby trails such as the Heart Rock/Seeley Creek Trail, which leads to a scenic waterfall.
Lake Gregory Regional Park does have a designated dog park. However, specific rules regarding where dogs are permitted on trails and in other areas of the park apply. It's best to check the official San Bernardino County Parks website for the most current regulations regarding dog access to ensure a pleasant visit for everyone.
The 2.7-mile fitness trail encircling Lake Gregory is generally flat and well-maintained, making it suitable for a wide range of visitors. While specific accessibility information for all facilities should be verified with the park, the main loop trail offers a relatively accessible option for enjoying the lake's scenery.
Private vessels and power boats are generally not allowed on Lake Gregory. However, rowboats, paddleboards, pedal-powered "water trikes," and paddle boats are available for rent. You can bring your own electric trolling motor to affix to a rented rowboat.
Lake Gregory is a man-made reservoir. Its construction began in 1937 under a Works Progress Administration (WPA) grant to dam the east and west forks of Houston Creek. The project was completed in 1939, and an urban legend claims that construction equipment left on the lake bed during exceptionally heavy rains in 1938 (which filled the lake in just three days instead of the estimated three years) remains at the bottom today.
The community of Crestline, adjacent to Lake Gregory, offers various cafes and restaurants. While there isn't camping directly at Lake Gregory Regional Park, there are accommodation options in Crestline and the surrounding San Bernardino Mountains. The San Moritz Lodge on the southeast shore, once a private club, now hosts special events and houses a senior center.
Lake Gregory is regularly stocked with brown and rainbow trout, making it a popular fishing spot. Anglers are required to have a valid California state fishing license and pay a county fee. Children under four can fish for free, and the park sometimes offers free fishing clinics. You can find more information on fish planting schedules via the California Department of Fish and Wildlife website.
While late spring through early fall is ideal for water activities, Lake Gregory offers a refreshing escape year-round. The cooler months provide excellent conditions for hiking the lake loop or nearby trails without the summer crowds. The surrounding cedar and pine forests are beautiful in any season, offering a tranquil setting for walks and enjoying nature.
Beyond the lake itself, the area is characterized by cool cedar and pine forests, providing a distinct mountain atmosphere. The Heart Rock/Seeley Creek Trail nearby leads to a unique heart-shaped rock formation and a waterfall. The south shore of the lake is also a popular fishing destination, offering scenic views.
