Mount Diablo Interpretive Association - Your Mount Diablo Connection

Mount Diablo State Park is one of the ecological treasures of the San Francisco Bay Area. Every season in the park has its special qualities. Discover for yourself the mountain's beautiful wildflowers, its extensive trail system, fascinating wildlife and distinctive rock formations. View the stars from its lofty heights, bike ride to its 3,849 foot summit or explore the more remote trails by horseback.

Mount Diablo Interpretive Association is a non-profit volunteer organization which assists the California Department of Parks and Recreation in maintaining and interpreting Mt. Diablo State Park for its 700,000 visitors each year. Through a continuing program of education, MDIA fosters appreciation and the enlightened use of Mount Diablo State Park. MDIA is proud to have played a major part in raising funds for the construction of the Museum atop the summit of Mt. Diablo.

In addition, MDIA helped develop the Mitchell Canyon Visitor Center and is operated by State Park Volunteers on the North side of the Mountain.

Our web site is designed to lead you to a wealth of information on the park and put you in touch with the varied activities on Mount Diablo.

Before starting your hike, visit our guide to reading trail signs.
