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.

Great hike with amazing views. A very rock trail on the way down

A ton of mud right now. Be prepared with good hiking boots. Have to cross a couple of small creeks, otherwise I'd say it's a moderate trail with some steepness, great views, and nice small waterfalls. Took about 4 hours at a leisurely pace with inexperienced hikers.

Trail is washed out about 1 mile in and completely impassable right now. Will need extensive repairs.

One of my favorite local hiking trails by far!! My 10 year old was able to do the whole loop and loved it!! Defined recommend it, but also recommend that you wear hiking shoes or boots during the rain season! Very muddy, but definitely worth seeing the amazing waterfalls.

Great hike! A little confusing to follow but overall a nice experience. Went after 3-months of rainfall. There were six creeks to cross and they ranged from easy to seemingly impassible (without getting your sox wet). Took us 3hrs from start-to-finish. Should be more of a 2.5hr excursion, though

With the heavy rains the waterfalls were exceptionally active. The beginning of the trail has a lot of mud so keep that in mind. Getting past the waterfalls leads to wet shoes since the water levels are high but it's not extreme. The views were beautiful. The loop trail to the waterfalls is steep and narrow (no barriers) so if you're easily spooked avoid going up the loop and stick to the main trail.

A good trail close to the Bay Area. Has some climbs that could be difficult for those who are out of shape. The waterfalls are well worth the climb. My wife and I hiked the trail in about 4 hours with several picture taking stops. The falls were in full flow due to the recent rain.

Fun hike on a sunny winter morning. Prepare to get your feet wet and muddy.

Great Hike! Good grades and the falls are gorgeous right now
