Need to Know

Open to hikers, equestrians, and mountain bikers; cyclists must ride on 2.1 miles of undedicated roadway.

Description

Watch raptors soar above open chaparral slopes, take in spectacular views of the Pacific Ocean, follow a moist creekbed, and cross shaded oak woodlands and redwood–fir forests. Hikers and equestrians descend into Frank Valley on the Miwok Trail and mountain bikers descend the Dias Ridge Trail; all users then make a steady climb to the Pantoll Ranger Station.

Cyclists will cross the northwest corner of Muir Woods on the Dias Ridge Trail, which is also accessible as a 3.1-mile one-way spur for hikers and equestrians. Cyclists must ride on 2.1 miles of undedicated roadway to connect to the Deer Park Fire Road.

This trail description is excerpted from the 2019 Bay Area Ridge Trail Guidebook. For details on all trails, trailheads and more buy the book from Wilderness Press.

This part of the Dias Ridge Trail leads to the peak, just before you start your descent.  Look for the line of dead pines and you'll be past the half way point.  All downhill from here on the west direction.
