Gaustatoppen

Gaustatoppen (1,883m) is frequently cited as the most beautiful mountain in Norway. A soaring, isolated stratovolcano-like cone in the Telemark region, it offers an astonishing reward: on a clear day, standing at the summit allows you to see 60,000 square kilometers—roughly one-sixth of the entire Norwegian mainland. The most popular hiking route begins at Stavsro, a steady, 2.7-mile (4.6km) rocky ascent up the mountain's wide shoulder. For an extra dose of adventure (or for those with mobility issues), you can use the 'Gaustabanen,' a Cold War-era funicular tram built inside a secret tunnel running straight up through the core of the mountain to the summit plateua.

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).
