Trailhead
Whiskeytown National Recreation Area, California
Boulder Creek Trail provides mapped foot access beyond Whiskeytown's developed-site exclusion areas to legal permit camping in the upper Boulder Creek backcountry.
Obtain the free permit at the visitor center, remain outside the pink exclusion zones, and camp at least 400 feet from roads and 100 feet from trails and streams; no campfires are allowed.
Seasonal access

NPS Boulder Creek trail access: Use the signed Boulder Creek Trailhead access in Whiskeytown National Recreation Area, California. Use mapped Boulder Creek Trail outside developed-site and road exclusion zones. Crystal Creek Primitive Camp is a separate seasonal vehicle-access camp, not a backcountry destination. Whiskeytown backcountry has no recurring closure window, but summer heat and wildfire, winter storms, post-fire hazards, and road or trail work can close an approach or permit area.
Obtain the free permit in person and verify the exclusion map, Boulder Creek Trail, fire status, and current park conditions before departure.
