Las Trampas Regional Wilderness

Las Trampas Regional Wilderness

Bollinger Canyon Rd, San Ramon, CA 94583, United States


    Las Trampas Regional Wilderness is a national preserve of 21,62 sq km found in Alameda and North California's Contra Costa counties. California Las Trampas is Spanish for the traps or the snares, and is Danville's next closest city. The park is a member of East Bay Regional Park District. It has two long hilly ridges (Easterly Trampas Ridge and Westward Rocky Ridge) near Bollinger Creek, a small valley that features a horse pond and parking for travelers. Some of the paths are steep; they can adjust elevations to as many as 900 feet (270 m). The park was described as "the hard man in the District of East Bay.

Vegetation on the southern and western slopes of the two ridges is predominantly: black sage, chamise and buck brush, with lesser amounts of toyon, hybrid manzanitas, elderberry, gooseberry, chaparral currant, sticky monkeyflower, coffeeberry, coyote bush, poison oak, hollyleaf redberry, deer weed and dozens of other species. There are thick deposits of fossils on some uncovered rocks. Rocky Ridge is 2,024 feet (617 m) long. The trail leads through EBMUD at an elevation of 1.760 feet (540 m). The trail goes either to the Valle Vista Staging Area on Canyon Road in Moraga or to the Castro Valley Chabot Station in the south. The trails continue to Las Trampas Ridge east from the Bollinger Creek, Chamise and Bollinger Creek Trail, with a good view of the Ygnacio, San Ramón and Amador Valleys, as well as the Diablo Range and the Carquinez Strait. There are two picnic areas, named Steelhead and Shady, near the parking lot. These are available on a first-come, first served basis and cannot be reserved. Reservable picnic sites for groups of 50 to 300 persons are at the nearby Little Hills Picnic Ranch. 

Bicycles on half trails are permitted; biking and equestrian on every trail. Dogs are allowed. Cows, calves and steers may be found, as well as an occasionally unreachable bull, on the trails; their pasture keeps the grass short for a fire in summer[1]. Their eye can also see wild wild wild wild wild wild wild wild widows and eagles. Laurel and live oak on the coast are the most common trees in California. Certain species include buckeye, broad leaf maple, live oak gorge, green oak and scrub oak. The latter seems to favor the hillside at the end of the Chamise Road, with its muzzletoe.

Bollinger Creek bisects the park. To the west is the Rocky Ridge, reachable via a paved trail by the car park, which takes people to the summit at 2.024 feet. At 1760 meters of alight, you can take a westward route to the Valle Vista Stadium on the Canyon Road of Moraga and south to the Chabot Stadium of Castro Valley on the East Bay Municipal Utility District. For walking on EBMUD property, a permit is required. The western pitch of Las Trampas is a vulnerable EBMUD habitat, and people who don't have a valid EBMUD permit are not permitted to take part in hikes.
