Las Trampas to Mt. Diablo Trail

This trail is an interesting way to access Mt. Diablo from Alamo. The trail rises quickly above the freeway and follows a right-of-way between horse properties and estates until it hits Stone Valley Rd. The trail follows the road for a short distance then picks up again on the other side of Stone Valley Rd with 2 quick gut buster climbs (steep but short).

A steady, but mostly shaded, climb takes you to the top of the Roundhill North neighborhood. From there, there is a flowy singletrack into one of the most beautiful valleys on Mt. Diablo (just West of Macedo Ranch). Follow the poorly marked trail through the grazed valley to reach the Macedo Ranch staging area and parking.

Cross the parking lot to reach the Briones to Mt. Diablo trail and to access Wall Point Road.
