Johnson Trail Camp is the most popular and accessible backcountry campsite in Humboldt Redwoods State Park, featuring primitive facilities including bear lockers, vault toilets, and untreated water.

The camp can be reached via two trailheads: a 5-mile hike from Big Trees Area (seasonal access) or a 6. 5-mile hike from Grasshopper Road (year-round), with the trail climbing approximately 1,400 feet to 1,600 feet elevation through old-growth redwoods.

Registration is required at any open campground entrance station before departure, and sites operate first-come, first-served year-round at $5 per person per night with a maximum of six people per site.
