The Bigfoot Trail is an unofficial U.S. long-distance hiking trail in northern California. The Bigfoot Trail was originally proposed by Michael Kauffmann in 2009 as a suggested route to navigate the Klamath Mountains from south to north as well as a long-trail to introduce nature lovers to the biodiversity of the Klamath Mountains region. The trail begins in the Yolla Bolly-Middle Eel Wilderness and ends in Redwood National Park at the Pacific Ocean near Crescent City, California. A major focus along the trail is conifer diversity, passing 32 species in 360 miles (580 km). The route crosses six wilderness areas, one National Park, and one State Park. Northwest California's Klamath Mountains foster one of the most diverse temperate coniferous forests on Earth, and this route is intended to be a celebration of that biodiversity.
