Colca Canyon (Cabanaconde to Sangalle)

Descending into the earth's crust. Colca Canyon is one of the deepest canyons in the world (3,400m). The classic trek starts in the high Andean town of Cabanaconde (3,280m) and involves a rapid, knee-jarring descent to the Colca River. Hikers pass through traditional Quechua villages where pre-Inca terraces are still active, before reaching the Sangalle Oasis—a lush, green sanctuary at the canyon floor. The return journey is an infamous pre-dawn 1,200m vertical climb that tests the lungs and legs of every hiker. Above, the sky is often filled with the massive silhouettes of Andean Condors, utilizing the morning thermals to rise out of the canyon's depths.

Deep within the Hohe Tauern National Park, the Prossautal is a valley that branches off the Kötschachtal near Bad Gastein. This long but mostly flat trail follows the Kötschach Ache river into a classic glacial box valley. The rock walls on either side rise significantly, with multiple thin waterfalls cascading down the granite faces. The trail ends at the Alpengasthof Prossau, a traditional alpine inn positioned near the base of the Tischler glacier.
