The Wave (Coyote Buttes North)

The Wave is perhaps the most heavily photographed and tightly regulated natural attraction in the American Southwest. Situated in the Coyote Buttes North Special Management Area of the Paria Canyon-Vermilion Cliffs Wilderness, it is a magnificent, surreal basin of swirling, intersecting U-shaped troughs of Navajo sandstone. The rock is fiercely striated with vivid red, orange, yellow, and white banding, formed by Jurassic-era sand dunes compacted over millions of years and then eroded by wind and water. Because the landscape is incredibly fragile, access is strictly limited by the Bureau of Land Management (BLM) to a tiny number of lucky lottery winners per day. There is no marked trail; hikers receive a pictorial map and GPS coordinates to cross wild, trackless slickrock and deep sand to locate the formation.

Starting at the end of the high-alpine Grossglockner High Alpine Road (Kaiser-Franz-Josefs-Höhe), the Gamsgrubenweg is a masterpiece of high-altitude trail engineering. It contours high above the Pasterze, Austria's largest glacier, leading into the heart of the Hohe Tauern National Park. The trail passes through several tunnels built to protect hikers from rockfall, eventually opening into the vast, tundra-like 'Gamsgrube' (Chamois Pit), a special protection zone where the rare flora and fauna of the high Alps thrive in the shadow of the Grossglockner (3,798m).
