Difficulty: Easy to Moderate
Length: 1 Mile Round-Trip
Sullivan’s Knob is a rock formation that looks like a giant anthill, about one mile north of the Devil Canyon Overlook junction. The hike begins in the parking area. Below the parking area two trails meet. One, an ancient trail, known as the Bad Pass Trail was seasonally traversed by American Indians moving between the Bighorn Basin and the Northern Plains.
Nature is reclaiming this trail, which at times seems to be camouflaged by the juniper, mountain mahogany, and sagebrush. The other, a modern trail, makes its way to the canyon rim and gives solitary views of the canyon. This is also a great place to try getting a triple echo. Look for Bighorn sheep and Peregrine falcons before yelling into the canyon.
