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.

The W-Trek is a multi-day hiking circuit in the Torres del Paine National Park, located in Chilean Patagonia. Distance varies by start/finish and side trips (e.g., Británico viewpoint). The route provides access to three major glacial valleys: the Ascencio Valley (Base Torres), the Francés Valley, and the Grey Valley. The trail traverses a landscape characterized by granite towers shaped by tectonics and glaciers, and large proglacial lakes such as Nordenskjöld and Pehoé. The W-Trek typically requires four to five days to complete.
