Fern Canyon is a canyon in Prairie Creek Redwoods State Park in Humboldt County, California. The park is managed in cooperation with other nearby redwoods state parks and Redwood National Park. It is named for the ferns growing on the 50-foot high walls, through which runs Home Creek. Fern Canyon is recognized as a World Heritage site and an International Biosphere Reserve.
In "High Adventure 2014", the Young Men hike to Fern Canyon through Prairie Creek. In Fern Canyon, Ryan Hales scales up one of the walls of the canyon. Dallin Earl tries to do the same, but has to use a tree root to get up.
