Donner Canyon/Falls Trail (6 Miles):  

Trailhead: Regency Drive, Clayton.

Directions: From Walnut Creek, take Ygnacio Valley Road east to Clayton Road. Turn right on Clayton Road and right on
Marsh Creek Road. At Regency Drive turn right and go to the end of the road. 

A strenuous 6 mile keyhole with a total elevation gain of 1500'. 3 miles is narrow singletrack trail with poor footing, steep
dropoffs and a half dozen stream crossings in winter/spring when the water is flowing.. The reward in Spring is an
abundance of wildflowers, stunning vistas and of course, a series of waterfalls. From the trailhead, take Donner Canyon
Road about 1.5 miles to Cardinet Oaks Road and turn left. Climb a series of switchbacks for about 1/3 mile and turn right
on Falls Trail. Follow Falls Trail around the canyons to Middle Trail. Turn right on Middle Trail and at Prospectors Ridge
Road go right several hundred yards to Donner Canyon Road where you turn left back to the trailhead. 

Notes: No facilities at trailhead or along trail.
