Grossglockner — The Gamsgrubenweg Trail

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).

Moro Rock is a giant granite dome located in the heart of Sequoia National Park. While arguably more of a monumental staircase than a traditional hike, ascending Moro Rock provides one of the easiest, most accessible, and most dramatic panoramic viewpoints in the entire Sierra Nevada mountain range. A marvel of 1930s Civilian Conservation Corps (CCC) engineering, a concrete and stone stairway consisting of roughly 350 steep steps is bolted directly and seamlessly into the sheer granite face. Hikers climb this narrow spine, with thrilling drop-offs guarded by iron handrails, to reach a flat summit at 6,725 ft (2,050m) that offers uninterrupted, sweeping views of the craggy Great Western Divide.
