About Us

Nestled in the hills along the northeastern slope of Mt. Diablo you'll find one of the best kept secrets in the East Bay-The Concord Mt. Diablo Trail Ride Association. We are a not-for-profit organization dedicated to horsemanship, land preservation and fun!

Our club spans over 200 acres of nature with direct access to beautiful Mt. Diablo State Park. While less than 10 minutes from downtown Clayton, when you're here you really feel like you are "in the mountains".

We offer gorgeous trails, monthly social potlucks, equestrian facilities, a club house with pool, horse boarding, horse camping, facility rentals, a rustic cross country jump course, horsemanship clinics, social events and very affordable membership fees.

At our core, we're a family of horse lovers and nature lovers. 

Our History

CMDTRA was established in 1941 and at that time owned property in what is now Concord Avenue near highway 242. Wondering why the Concord Mt. Diablo Trail Ride Association is located in Clayton? You'll find the answer to that question along with our complete historical "story" described in a document called "Pastime", accessible by clicking here.
