Preserve Highlights & Features
Off-leash dog area
Visitors can let their dogs off-leash in the 17.5-acre area located in the center of the preserve, accessible from the Cordilleras Trail, Polly Geraci/Hassler Trails and the Blue Oak Trail. While in this area, visitors must have a leash in their possession and their dog must be under voice control.
Note: Area is fenced and signed at entrances, but there is no fencing around the off-leash area. Dogs must be on a leash when outside of the off-leash area.
Wildflowers
Wandering the trails in early spring, visitors will see many wildflowers, such as Indian warrior, hound's tongue, mule's ears, and milkmaids, in addition to three members of the lily family: fetid adder's tongue, giant trillium, and mission bells. Pulgas Ridge is home to about 90 native species of trees, shrubs, ferns, and flowers.
