Peek-a-boo Canyon and Spooky Gulch are among the most famous slot canyons in the state of Utah. This moderate 3.5-mile trail is a loop trail located near the town of Escalante, where you can hike through the narrow sandstone canyons, admire the striking red walls of the canyon, and enjoy the beautiful rock formations found in the canyon. Peek-a-boo Canyon has some interesting challenges and beautiful places with good camera opportunities, but the Spooky part is very tight and quite adventurous.
