Lençóis Maranhenses National Park Trek

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.

The Nahuel Huapi Traverse is a multi-day hut-to-hut route that circumnavigates the mountain ranges adjacent to San Carlos de Bariloche. The trail follows a high-alpine path, connecting four distinct mountain refugios via ridgelines, loose scree slopes, and granite passes. The terrain is characterized by a mix of Andean forest and exposed high-altitude terrain, where route-finding and stability on loose rock are primary requirements. The system of stone huts (refugios) provides a logistical framework for the journey, though hikers must be prepared for sustained physical output in an exposed mountain environment.
