Coburger Hütte — Seebensee & Drachensee

This is one of the most celebrated hikes in Tyrol, connecting two distinct alpine basins. Starting from the Ehrwalder Alm, a broad forest path leads to the Seebensee (1,657m), a turquoise lake that perfectly reflects the Zugspitze (2,962m) on clear days. The adventure continues with a steep, serpentine ascent of another 300 meters to the Coburger Hütte and the moody Drachensee (Dragon Lake). The hut sits on a high rock rib, overlooking both lakes and providing one of the most dramatic mountain vistas in the Mieminger Gebirge.

Lençóis Maranhenses is a vast field of mobile sand dunes positioned along Brazil's northeastern coast. The landscape is defined by the seasonal accumulation of rainwater in the valleys between dunes, creating thousands of clear freshwater lagoons from May through August. The 43km trekking traverse between Atins and Santo Amaro involves sustained walking across soft sand slopes and navigating between the remote Baixa Grande and Queimada dos Britos oases. The primary challenge is the combination of high thermal stress, intense solar reflection from the white sand, and the physical load of soft-substrate movement.
