Parking
Cathedral Butte Trailhead is outside the park, about 18 miles down Beef Basin/Bridger Jack Road (County Road 107); high-clearance four-wheel drive may be needed, and the road may be impassable in winter or when flooded. Arrange a shuttle. At the Peekaboo end, the park advises parking at Cave Springs/Salt Creek Gate and walking the road to Peekaboo; parking near Peekaboo or along Salt Creek-Horse Canyon road is discouraged because of flash-flood danger.
