Overview

This 3-day trekking itinerary across Lençóis Maranhenses National Park offers a beautiful journey through its vast dune fields. Over the course of the trek, hikers walk along the continuous white sand dunes and have the opportunity to rest and swim in the park’s freshwater lagoons. The route traverses the varied landscapes of the national park, allowing for a sustained observation of its natural environment.

The extended duration of this trek includes overnight stays in the local oases within the park. Resting in the homes of the traditional residents provides a direct cultural exchange. This immersion allows hikers to observe the daily routines and lifestyle of the families who inhabit the interior of the park, adding a practical cultural dimension to the physical journey.
