Grass Valley Wilderness Area

Grass Valley Wilderness Area is a 32,886-acre federally protected wilderness in California managed by the Bureau of Land Management. As a designated Wilderness Area, it is primitive backcountry open only to non-motorized travel—no roads, motors, or mechanized equipment are permitted. The landscape offers hikers and backpackers a chance to experience undeveloped terrain and genuine solitude away from developed infrastructure.

Visitors should expect a true wilderness setting where you are responsible for self-sufficiency and environmental stewardship. All travel is on foot, and Leave No Trace principles are essential: pack out everything you pack in, camp only in designated areas where permitted, and minimize your impact on the landscape. Water sources, trail conditions, and seasonal access vary, so come prepared with maps, adequate supplies, and knowledge of current conditions. Check with the BLM before your trip for any closures, permit requirements, or seasonal restrictions.
