At the eastern fringe of the San Francisco Bay Region, Mount Diablo, elevation 3,849 feet, stands alone on the edge of California’s great Central Valley. At this point, the Coast Range consists only of low hills, none high enough to block the view from the upper slopes of the mountain. As a result, the view is spectacular. 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, 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 meet to form the twisting waterways of the Delta. To the east beyond California’s great Central Valley, the crest of the Sierra Nevada seems to float in space. With binoculars, you may even be able to pick out Half Dome in Yosemite National Park. Mount Diablo State Park is one of the ecological treasures of the San Francisco Bay Area. Every season in the park has its special qualities. Discover for yourself the mountain's beautiful wildflowers, its extensive trail system, fascinating wildlife and distinctive rock formations. View the stars from its lofty heights, bike ride to its 3,849 foot summit or explore the more remote trails by horseback. The park offers hiking, biking, horseback riding and camping. Dogs must be on a leash under your control at all times. Dogs are not allowed on trails. Dogs must be in a tent, camper or enclosed vehicle during the night. Gates open 8am and close at sunset. Visitors should plan to be in their vehicles by sunset and headed out to avoid being locked in.

I completed the summit hikes yesterday. It was below 80 degree and the weather was perfect for hiking. I went up on Back Creek Trail, which is a strenuous steep ascend. But the trail is pretty well maintained and easy to negotiate, comparing to Eagle Peak Trail. And the trail continued to Bald Ridge Trail and Summit Trail. The view at the summit was excellent. It was a bit crowded at the main parking lot. I went to the other side of the summit where there are plenty of picnic tables and a clean restroom with hardly any people. That is the perfect place for a picnic after the thigh busting hike.

I took the Juniper Trail, Deer Flat Creek Road and Mitchell Canyon Road back to the Mitchell Canyon Visitor Center. This is an easier route as it is fire road most of the way, and it is wide, smooth and not as steep. As a bonus, I saw two tarantulas along the way less than a mile from the Visitor Center.

This is one of the toughest hikes I've ever done. It's definitely worth it.

Trail from Finley Road trailhead is now accessible! Bob's pond approach on Tassajara Creek Trail from north has a washout, but is passable. The trail from the picnic table to Riggs Canyon Road has a few downed trees, but again is passable. Watch out for poison oak!!
