Rated as difficult, Harmonica Arch is a grueling 5.4-mile out-and-back trail complete with butt-busting inclines, out-of-this-world scenery, and some of the best wildlife sighting opportunities in the state.

Since most Colorado hikes are downright beautiful, what makes Harmonic Arch stand out from the rest? It is thanks to this pièce de résistance: the namesake arch.

Standing 30 feet tall and spanning 85 feet long, Harmonica is one of Colorado’s longest arches that just so happens to also be surrounded by unforgettable 360-degree views.
