The Pass of Horns is one of the few places where people can cross from one side to the other of this imposing mountain range, which is both a physical and political barrier. Three outposts - North Watch Peak Watch, and Woodway - guard the main trail leading through the pass. The central trail circles the base of Horn Peak, a climbing challenge for thrill-seekers. Side trails offer adventurous or circumspect travelers routes that avoid official impediments, but they all have hazards of their own. One of the side trails leads to Icefall, a waterfall that purportedly has magical properties.
