Cerro Tronador (Refugio Otto Meiling)

This two-day Patagonia hike leads to Refugio Otto Meiling on the slopes of Cerro Tronador, one of the most prominent peaks in the Bariloche region. The route climbs through coihue and lenga forests before emerging onto a high rocky ridge that culminates at the refuge (1,905m). Positioned between the Castaño Overa and Alerce glaciers, the stay offers a unique opportunity to witness active glacial calving. The trail follows a well-defined path of forest floor and alpine rock, with a final sustained push to reach the rocky spine where the hut perches.

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.
