Grass Valley Wilderness

General Maps Contacts Area Management Wilderness Laws


The United States Congress designated the Grass Valley Wilderness (map) in 1994 and it now has a total of 30,186 acres. All of this wilderness is located in California and is managed by the Bureau of Land Management.


The expansive Grass Valley covers nearly three-fourths of this Wilderness and ranks as its primary topographical feature. The area lies fairly flat, with a series of scattered hills, yellow to reddish brown in color, with elevations from 200 feet to 600 feet above the desert floor to the west.

You'll find a few Joshua trees, but the vegetation is dominated by a creosote bush scrub community. Raptors forage here, and desert tortoises and Mojave ground squirrels find suitable habitat in this barren area, which is devoid of both water and trails. The non-Wilderness corridor of an old road divides the Wilderness into eastern and western halves, and the China Lake Naval Weapons Center shares the eastern border.
