Mount Diablo State Park Mountain Bike Trail Map

Guide to the best mountain bike trails in Mount Diablo State Park.
Diablo Mountain Biking 

Area Summary
Location: Walnut Creek vicinity
Best For: Strong Intermediates
Suitable For: All levels
Ground Cover: Open grasslands, chaparral, oak woodlands
Seasons: Best from late fall through mid-spring. Usually hot in summer. Can be muddy with heavy rain.

Just as it reigns over lesser peaks in the East Bay skyline, Mount Diablo has a deserved reputation as the crown jewel of East Bay mountain biking. For sheer variety of terrain and quantity of trails, Diablo can't be beat. Mount Diablo also boasts stunning and sometimes unusual beauty, great views and a variety of wildlife.

While rides of all levels can be fashioned, Diablo's bike trails definitely cater to strong intermediates and better. Though only a few sections of single-track are open, the fire roads tend to be steep and rugged. Be prepared to walk on some trails and use extra caution (seat down, weight back!) descending.

A note about Diablo single-track. The official policy is that single-track trails are considered closed to bikes unless expressly designated as multi-use. However, in some instances there is substantial inconsistency between printed information, online information and trail signage as to whether a trail is multi-use.
