If you go
From Los Angeles, take Interstate 10 east to Palm Springs. In Palm Springs, exit on North Gene Autry Trail (California 111) and head south about six miles. Turn left on East Palm Canyon Drive. As you pass Rimrock Shopping Center, turn right on Palm Hills Drive and find a parking spot. The dirt road that heads up the hill takes you into the canyons and hills that are home to the "goat trails." You can stock up on water and snacks at the shopping center. Cellphone service on goat trails can be spotty, but take your phone just in case.
