About the Madhatters

Our club meets at 7:00pm on the 4th Tuesday of every month.
For August 25, 2026 we’re at Straw Hat Pizza in Brentwood.
You can also attend via Zoom (many of us do). Please get in touch with a board member for Zoom meeting info.


We are a Northern California, family oriented organization, established in 1978.  We are affiliated with the California Association of Four Wheel Drive Clubs Inc (Cal4Wheel.com), Blue Ribbon Coalition (BRC), and California Off-Road Vehicle Association (CORVA).


We schedule outings (runs) at least one per month, have an annual club picnic during the summer for family, and finish the year off with a Christmas party and fund raiser.  We also attend and support numerous Cal4Wheel events during the year (Winter Fun Fest, Annual Convention, District Meetings, Sierra Trek, etc.).  We adopted parts of the Fordyce and Rubicon trails and work closely with the U.S. Forest Service to help maintain the trails for everyone to use and enjoy. Make sure to check out our Calendar to know what is going on at all times!

We strongly support and practice the “Tread Lightly” concept and support legislation to preserve off-road vehicle access rights to State and Federal lands.  We welcome all off-road enthusiasts (from stock to buggies) to join us in the fun and challenge of off-roading.  

Vehicles must meet Cal4Wheel minimum safety standards / requirements.
