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.

Voted Austria’s most beautiful place in a national poll in 2016, the Kaisertal is a legendary valley nestled between the Zahmer Kaiser and Wilder Kaiser massifs. For decades, it was the only inhabited valley in Austria with no road access. Even today, only residents are allowed to drive, making it a hiker's paradise. The journey begins with the 'Kaiseraufstieg'—a relentless series of nearly 300 vertical steps that lead over the Sparchner Gorge. Once past the stairs, the valley opens into a pastoral world of historic mountain inns, chapels, and soaring vertical limestone walls.
