The Castle Crags Wilderness, located in the Shasta-Trinity National Forest was created by the 1984 passage of the California Wilderness Act. This 10,500 acre pristine region contains towering spires, sheer canyons, and sparkling alpine lakes. Mixed conifer forests prevail on north, east and west facing slopes while scrub brush and rocky slopes generally predominate elsewhere.

• Hike the Pacific Crest Trail which runs for 19 miles through Castle Crags, offering fantastic views of surrounding rugged peaks.
