Another Awesome, Community Powered Dig Day!
Announcement - February 11, 2026
There was so much trail goodness at Mount Diablo State Park this past Saturday!
100 volunteers joined California State Parks and Mount Diablo Trails Alliance, improving Lower Summit Trail (Dan Cook Singletrack) with a focus on accessibility, sustainability and surface water drainage using proven techniques.
A large contingent of students attended this Dig Day, and it was truly inspirational, as they represented more than 50% of the volunteers. The students helped improve the trail despite unfriendly, rock-hard soil conditions.
Huge Turnout from Off-road Cyclists
We’d like to recognize the local mountain bike teams who gave up their Saturday to give back to the State Park:
CC Composite MTB
MVHS MTB
SRV MTB
They showed up on time for the early start and engaged in a thoughtful discussion with the California State Parks Diablo Range District Superintendent, Clint Elsholz.
There were many inclusion-based topics covered during the Q&A session with Mr. Elsholz, including:
Responsible recreation practices
Differences in safety and bike accident rates on trails vs. fire roads
Change-in-Use process for singletrack trails
Potential pilot concept ideas (e.g., Briones) for expanding off-road cycling access to singletrack trails beyond the 2016 RTMP

Sunlight. Camera. Action.

Make a Charitable Donation
Help us reach our inaugural fundraising milestone of $50,000 by March 1, 2026. Trails 2035 will not achieve its ambitious goals without community funding, especially given costs associated with the change-in-use (CIU) process, ADA-compliant trail construction projects, and trail maintenance projects conducted in sensitive species zones.
