Beautiful hike along creek, multiple cascades, mountain views.
Donner Creek Falls consists of a series of four separate cascades falling off the peaks of Diablo. During the winter months and after a good rain, the waterfalls are rather impressive.
From the parking area, walk along Donner Canyon Rd to Hetherington Loop (1.0 mi). After about 1.8 miles, turn left at the Cardinet Oaks Rd., and follow this road across Donner Creek and up a steep section to a junction with the Falls Trail on the right. This trail leads down to the falls on Donner Creek and continues on to the Middle Trail, which then loops back down to the Donner Canyon Rd.
From I-680 in Walnut Creek (heading south), take the Treat Blvd. exit. Drive east for 1.0 miles to Bancroft Rd. Turn right and drive 1.2 miles to Ygnacio Rd. Turn left and drive 5.4 miles to Clayton Rd. Turn right and drive 2.9 miles to Regency Drive (Clayton turns into Marsh Creek Rd., but don't turn at the sign for Marsh Creek Rd.). Turn right on Regency Drive, and drive 0.6 miles to the end of the road.
If heading north on I-680 in Walnut Creek, take Ygnacio Valley Rd exit, and drive east for 7.5 miles to Clayton Rd.
