Griswold Hills

Griswold Hills

Within the steep and rugged Griswold Canyon, BLM land straddles both sides of the road. Visitor service improvements are now complete at the new day use facility, which features a parking area, a shade structure, picnic benches, a vault toilet, and a kiosk providing an interpretive panel, a map, and information about the area.

Ridge Hike at Griswold Hills


Adventure is at Your Fingertips


Dispersed camping is available at Griswold Hills, although there is no camping within 200 yards of any wildlife watering improvement.  Please remember to bring a shovel with you for both personal sanitation and fire prevention purposes.  There is a 14 day camping limit within any 28-day period.


There are three main types of hunting available, including upland game bird, small game, and big game like deer and wild pigs.  Varmint (non-game) hunting is also allowed.  The California Department of Fish and Wildlife regulates the hunting seasons for different species and the types of firearms allowed for use.  Please be aware that this region is home to the California Condor and affects non-game hunting.

 At Griswold Hills, you may find upland game birds, varmints, and small game.


In the spring the hills are covered with mariposa lilies, Indian Paintbrush, poppies, and wild sage.  There is also good habitat for the foothill yellow-legged frog and the western pond turtle.
