Prossautal — A Glacial Box Valley in Hohe Tauern

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.

Consistently ranked as one of the best treks in the world, the Santa Cruz weaves through the heart of the Cordillera Blanca. Surrounded by dozens of 6,000-meter peaks—including Huascarán, Peru's highest mountain, and Alpamayo (often called often regarded as one of the most beautiful mountain)—this 3-to-4-day route cuts a dramatic path over the soaring Punta Union pass at 4,750m. Hikers traverse surreal turquoise glacial lakes, sprawling alpine meadows, and desolate moraines in a truly formidable high-altitude environment.
