Welcome to the Mount Diablo Interpretive Association Website


Mount Diablo Interpretive Association (MDIA) is a non-profit all-volunteer organization that assists the California Department of Parks and Recreation in maintaining and interpreting Mount Diablo State Park for its 700,000 visitors each year. Through education, sponsored activities and publications, MDIA fosters appreciation and the enlightened use of Mount Diablo State Park. MDIA is proud to provide the resources necessary to keep the Summit Museum and Mitchell Canyon Visitor Center open throughout the year. In addition, one of MDIA’s key roles is supporting the “Volunteers in Parks” program, which trains and manages park docents, sponsors guided hikes, helps maintain trails, and much more


New Online Wildflower Identification Guide


MDIA’s new online wildflower photo guide is intended to help you identify the wildflowers that you may see in Mount Diablo State Park throughout the blooming season. The wildflowers are categorized by color and are listed in alphabetical order by common name of the plant.

This guide is a work in progress, conceived and maintained by volunteers. More wildflowers, photos, and information about the plants will be added as the wildflower season progresses and volunteer time permits.

The online guide can be accessed either by clicking the flower on the left, navigating the menu via Park Information > Nature > Plants > Wildflower Identification Guide, or using this link: Wildflower Identification Guide


The Trail Through Time Audio Tour Is Now Available

New Multimedia Guide to Bay Area Geology linked to historic walk on Mount Diablo

The Trail Through Time  Audio Tour is a 6.3 mile walk from the top to the bottom of Mount Diablo through 190 million years of geologic history. Starting this month, you can enliven that hike with a multimedia guide produced by the Mount Diablo Interpretive Association. In the guide, MDIA naturalist Ken Lavin informs and entertains at 19 stops along the Trail Through Time route. Each stop is a short video segment you can download to your computer, tablet, or mobile phone to use at home or on the mountain.

Part one examines the ancient rocks at the top of the mountain—some of which have traveled 3,000 miles to get here. Part two introduces the younger rocks farther down. They date back to the times when dinosaurs and, millions of years later, saber-toothed cats and dire wolves roamed the Earth. Part three explains how Mount Diablo’s geologic secrets were discovered and how the Trail Through Time was built.

“This tour is not just for students of geology,” says MDIA president Mike Woodring. “It’s for people who want to understand how Mount Diablo and the rest of the Bay Area came to be—and what’s happening right beneath our feet today.”

The tour is part of the Audible Mount Diablo series, jointly produced by MDIA, Save Mount Diablo, and Audio Guides to the Outdoors. All 12 tours in the series are available free at audiblemountdiablo.com and at the link on this page to the top left.


Volunteer Opportunities

MDIA encourages the public to join our organization and become involved in its mission to support the park. We are always looking for dedicated volunteers to lead or help with various programs, outreach and operations. Volunteers can commit to as little as a couple of hours a week or volunteer on a project-specific, ad hoc basis and still provide vital assistance.(read more).
