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 coordinating the “Volunteers in Parks,” program, which trains and manages park docents, sponsors guided hikes, and helps maintain trails.


Water Shortage in Mount Diablo State Park
updated 12/19/14

California is in the midst of its third straight year of drought. The entire state is in some stage of drought with more than 77% of the state experiencing “extreme” to “exceptional” drought conditions. The majority of the water used by park visitors at Mount Diablo State Park is produced through a series of springs that is fed to various water tanks. Once at the water tank, the water is treated and tested before being ready for public use. However, with the lack of rain the past three years, the springs on the mountain have been reduced to a trickle and water tanks are close to empty.

In order to meet the park’s basic water needs until the rainy season, the park has been forced to take a number of drastic measures in order to conserve water:
  • All of the water faucets located in the picnic areas and Rock City have been turned off as a result of the drought.
  • The restrooms at the Live Oak Campground are closed.
  • The Live Oak Campground closes on a seasonal basis from November 1st through March 31st. 
  • Flush toilets are available at the Juniper Campground, the Lower Summit Parking Lot and the Upper Summit Parking Lot.
  • Water at the Juniper Campground has been turned on with the restrooms, showers and water faucets available for use.


ALL VISITORS ARE ENCOURAGED TO BRING WATER FOR CONSUMPTION DURING THEIR VISIT.

If you are planning a long hike, run, walk, bicycle ride or horseback ride, please bring plenty of water to ensure a safe and enjoyable visit. It is not unusual for heat-related illnesses (heat cramps, heat exhaustion and heat stroke) to occur at Mount Diablo State Park during the late spring, summer and early fall seasons. Although many of these illnesses can be treated without hospitalization, some heat related illnesses have proven fatal to park visitors in the past. By taking the necessary precautions, the vast majority of visitors enjoy a safe and memorable visit to Mount Diablo in all seasons.

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).

The Falls Are Flowing Again in Mount Diablo State Park!
12/18/2014

Recent rainfall has created a welcome opportunity to view waterfalls and cascades at their gushing, sparkling best. The popular Falls Trail can be accessed from Regency Gate, located just east of the town of Clayton. Drive to the end of Regency Drive and park along the street, taking care to not block residents' driveways.

Falls
Here are some tips for planning your hike:

Be prepared to hike approximately 6 miles (4 to 6 hours) with an elevation gain of over 1,000 feet. Allow plenty of time to return before sunset.

Use caution and wear appropriate footwear as trails and stream crossings may be muddy and slippery.

Consider bringing a change of clothes, especially shoes and socks, and a plastic bag in which to store the muddy items, so you don’t track mud into your vehicle.

Carry an accurate map of the area in case your plan or the weather changes.

 You may pick up a free Falls Hike handout/map or purchase a Trail Map of Mount Diablo State Park at the Mitchell Canyon Visitor Center onFalls QR Code weekends from 9 a.m. to 3 p.m., or you may order a map from our online store. The trail map is also displayed in the Regency Gate display shelter at the Donner Canyon Road trailhead. A smartphone map with specific Falls Hike information can be downloaded for $2.99 using the QR code link from pdf-maps.com or avenza.com. Get the app and the map by searching for “Falls Loop Hike”. By purchasing a map, you are donating to Mount Diablo State Park.
