Currently the Hellman Park Trailhead, which includes the Peppergrass and Mariposa Trails, is closed. When the trailhead (and trails) reopen (expected to be in April) NEW TRAIL HOURS will be in effect for Hellman Park Trailhead. New trail hours will be OPEN 9am-6pm June 1 through September 30, and 9am-5pm October 1 through May 31. Also, no bikes will be allowed on either of these trails. These changes are being made to protect the natural resources and enhance the visitor experience.
The rest of the Preserve trails remain unchanged, and are open sunrise to sunset.
