Bay Area Backcountry: La Costa Valley

Part of the East Bay Regional Park District - this is the western end of the Ohlone Trail.

This is wilderness. Water is scarce, and in summer can be non-existent. For a short visit, approach from Del Valle Regional Park then head for Murietta Falls. The trail to the falls is extremely steep - probably rivals Henry W. Coe for steepest trail - but the trip is worthwhile.

Backcountry permit required.

This is wilderness. Follow the Ohlone Wilderness Trail to either Del Valle Regional Park or Mission Peak Regional Park . Within the wilderness, check out Little Yosemite - a small valley which is almost exactly unlike Yosemite.

There is a very small campground with water and toilets, plus a trail camp for backcountry camping. Reservations are required in advance.
