DEHA Fall Obstacle Play Day at CMDTRA 

Please join us at our Obstacle Play Day as we ride our horses over 12 obstacles under a canopy of stately Oak trees on beautiful Mt. Diablo. This event will be held in historic Cardinet Oaks located on the Concord Mt. Diablo Trail Ride Association's property. Obstacles will be made primarily from natural materials against a backdrop of lovely views.  

IMPORTANT MESSAGE: Please note that this event will not be held in an enclosed arena. Cardinet Oaks is an open area under a grove of oak trees. All participants will ride or walk a little over 1 mile on a fire road from the staging area to Cardinet Oaks. There are some slight uphill and downhill grades. Car rides will be available for spectators upon request. Please be sure to bring a halter and a lead rope to tie up when the course overview takes place first thing in the morning. 

PLEASE  NOTE: All participants to provide their own horses. Neither DEHA nor CMDTRA can provide horses for this event, unless by private arrangement.

Obstacle Coaches:   To be determined
