Waterfall loop at Mount Diablo State Park

Overview: While Mount Diablo State Park is best known for towering vistas from the mountain's twin East Bay summits, the seasonal rains that visit the San Francisco Bay Area every year create several scenic waterfalls in the mountain's rugged canyons.

This hike starts out from the Regency Gate in the East Bay town of Clayton -- parking is free in the neighborhood: be polite and do not abuse the privilege.

Thanks to EveryTrail user Edgar Stiles for tracking this route. His hike:

Regency Gate > Donner Canyon Road > Cardinet Oaks Road > Falls Trail > Middle Trail > Meridian Ridge Road > Meridian Point Trail > Back Creek Trail > Back Creek Road > Regency Gate.

Mount Diablo phone: 925-837-2525

Hours: 8 a.m. to sunset.

There is no drinking water at this trailhead, though you could filter water from the seasonal stream.

Tips: This route can be very muddy; try to wait a few days after the most recent rain to give the trails a chance to dry out.

Driving directions: From I-680 at Walnut Creek, take Ygnacio Valley Road east to Clayton Road, turn right on Clayton Road, and right on Marsh Creek Road. Turn right at Regency Drive and park at the end of the road.
