Welcome to the Mount Diablo Interpretive Association Website

Mount Diablo Interpretive Association (MDIA) 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 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, and through the Volunteers in the Park Program, train and manage the many park docents, sponsor guided hikes, and help maintain trails.

Volunteer Opportunities For Our Members

The Association encourages the public to join MDIA and become involved in its mission to support the park. Volunteers can commit to as little as a couple of hours a week and still provide vital assistance. If you are interested in any of these opportunities and would like more information:

Park Announcements And Events 

• The Amgen Tour of California Bike Race is scheduled to pass through Mount Diablo State Park around mid day on May 15, 2012.  The race will enter the park from South Gate Road and then proceed past the Junction Ranger Station to exit the park on North Gate Road.  The bike race will not go to the summit.  Travel through the park will be severely restricted during the race and any cars on the road will be asked to park in designated areas. Intersections and some roads will also be closed as the race progresses through the park.  We will update the website as details become available. Interested individuals can also access information on the Amgen website at amgentourofcalifornia.com.  For more information about the activities on May 15th visit the Mount Diablo State Park website at www.parks.ca.gov/?page_id=517.
  
   
• Due to leaks, the observation deck on the Summit Museum will be closed until further notice. The State Park  Staff is currently working on a repair plan which will open the observation deck to the public later this Spring as the rain subsides. We will update this website with the opening date as soon as these plans are finalized. .

Spring Wildflowers Are In Bloom and Waterfalls are Full

• With the late rains finally reaching the mountain, spring wildflowers are blooming and the waterfalls are full. Attend one of our guided hikes to the falls or see the best blooms with one of our experts by going on one of the hikes listed on the MDIA  events calendar. 

• Even if the rain keeps you indoors, you can "visit" Mount Diablo by clicking on our Visual or Audio tours. Click on the links below to see different parts of the park or listen to an audio guide.  Both are great ways to prepare for your next visit to the park.
