Combining the popularity of ghost stories with the traditional aspects of a park trail guide, these creepy hikes lead courageous climbers and armchair adventurers through some of the scariest, most mysterious places in North America.

Thoroughly investigated, yet often tongue-in-cheek, these tales behind the trails include the chupacabra that roams the swamps inside the Big Thicket National Preserve, the execution-style shooting of two General Motors executives at Crater Lake, and the pair of disembodied legs that have been seen running around inside the Mammoth Cave Visitor Center.

A fright factor rating is listed for each hike, along with information on trailhead access, maps, and hike difficulty levels. From the wheelchair accessible to multi-day treks into the wilderness, the included trails cover a wide range of hiking abilities and even feature a haunted Louisiana bayou best reached by canoe or kayak.
