#1 - Donner Creek Loop Trail
Mount Diablo State Park
moderateYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarGray Star(1304)
Length: 5.1 mi • Est. 2 h 50 m
This is a beautiful hike along creeks, multiple cascades, and features mountain views. This loop trail is a great short hike that allows users to escape into the wilderness for a few hours. 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. Users report that parking at the trailhead is for residents only and you may get a ticket. Paid parking is available at the nearby Mitchell Canyon Visitor Center for $6.Show more

hardYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarYellow StarGray Star(827)
Length: 6.2 mi • Est. 3 h 30 m
The Grand Loop offers a bird's-eye view of the Bay Area, and sometimes glimpses far beyond, of the Farallon Islands, Mount Lassen, the Sierra Nevada, and the Santa Cruz Mountains. It's also a hotspot for wildflowers in the spring. From Juniper Campground follow Deer Flat road to the northwest to gain Meridian Ridge. A mild descent along the ridge leads through valley oak and grey pine to a crossing of Deer Flat Creek where the trail begins to climb to the prominent knoll on Bald Ridge. Continue on Bald Ridge Trail passing by brilliant displays of wildflowers in spring and early summer, until you reach Prospectors Gap. Stay south and follow north peak trail as it wraps you west around the base of Mount Diablo before connecting you back to the parking lot at the campground. Show more

Length: 7.9 mi • Est. 4 h 20 m
This hike has two starting points. This route follows the trail's alternative trailhead off of Mitchell Canyon Road. The main trailhead begins at the end of Regency Drive and Mountaire Parkway. Limited parking is available on Regency Drive. Parking at Regency Drive is for residents only and you may get a ticket. Paid parking is available at Mitchell Canyon Visitor Center for $6. Winter and spring rains create scenic waterfalls in this hike at Mount Diablo, the East Bay's signature peak. 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.Show more

The lush greenery of Mitchell Canyon leads to an invigorating climb to Eagle Peak (2,369'), a favorite of local hikers. Everybody loves to visit the summit of Mount Diablo, but many seasoned San Francisco Bay Area hikers prefer this hike to Eagle Peak via Mitchell Canyon, which takes in all the features that make Mount Diablo State Park unique. Mitchell Canyon is shady with abundant wildflowers in the spring; Eagle Peak culminates a rugged hike to jaw-dropping vistas of the East Bay and surrounding terrain. On a clear winter day you might be able to spot the snow-capped peaks of the Sierra Nevada.Show more

Length: 7.6 mi • Est. 4 h 33 m
$10 entrance fee to park at the Rock City entrance. From Rock City hike up to the summit. This trial offers scenic views and breathtaking climbs. Although steep in sections, it is a great hike. This park is one of the ecological treasures of the San Francisco Bay Area. Many visitors to Mount Diablo head straight for the summit to enjoy the famous view. Summer days are sometimes hazy, and the best viewing is often on the day after a winter storm. Then, you can look to the west, beyond the Golden Gate Bridge, to the Farallon Islands; southeast to the James Lick Observatory on Mount Hamilton at 4,213 feet elevation; south to Mount Loma Prieta in the Santa Cruz Mountains at 3,791 feet elevation, north to Mount Saint Helena in the Coast Range at 4,344 feet elevation, and still farther north to Mount Lassen in the Cascades at 10,466 feet. North and east of Mount Diablo the San Joaquin and Sacramento Rivers converge to form the twisting waterways of the Delta. To the east beyond Califomia's great central valley, the crest of the Sierra Nevada seems to float in space.Show more
