Devil's Creek is a popular attraction that flows through Boulder Cave for about 300 feet. The cave was formed when a sharply overhanging canyon wall fractured off from one side and bridged over the creek. This route enters the upper entrance to the cave and follows a trail. After exiting the lower end of the cave, you can either take the wooden steps back to the trail or continue down Devil’s Creek Canyon. The canyon is gorgeous with overhanging walls. It is an easy and popular hike with some wading in a small stream. When the canyon ends, follow the trail back to the parking lot. This route requires no special equipment, but a permit is required.
