Morning light cuts across the Preguiças like a curtain being pulled back. You push off in a speedboat at about 8:20 AM, the river daring you forward through channels threaded with mangroves; the current nudges the hull while white sand dunes appear and recede on the horizon. In 40 minutes the village of Vassouras rises from the riverbanks—trees alive with playful capuchin monkeys and shallow lagoons that swell during the rainy season.

Morning light cuts across the Preguiças like a curtain being pulled back. You push off in a speedboat at about 8:20 AM, the river daring you forward through channels threaded with mangroves; the current nudges the hull while white sand dunes appear and recede on the horizon. In 40 minutes the village of Vassouras rises from the riverbanks—trees alive with playful capuchin monkeys and shallow lagoons that swell during the rainy season.
This corridor of the Lençóis Maranhenses connects geology, culture and livelihood: wind-sculpted dunes that hold seasonal lagoons, mangroves that filter tidal flow, and riverside communities shaped by fishing and handcrafted trade. Mandacaru’s lighthouse, a local landmark, offers a wide, functional view that helped guide boats for generations; nearby stalls sell coconut ice cream and caipirinhas made with regional fruit.
The last stop, Caburé, is a sandy spit split by river and sea—an exercise in contrasts where surf and estuary converse. Expect easy terrain: short boat transfers, flat sandy walks, and a brief climb at the lighthouse. The tour runs roughly 2.5–3 hours, with a relaxed rhythm of photo stops, brief swims in seasonally deep lagoons, and a beachside lunch.
Practical notes: bring reef-safe sunscreen, insect repellent, a towel and cash for local vendors. Follow the pilot’s safety brief, respect wildlife (no feeding), and time your visit—rainy months fill lagoons for the best swims, drier months expose more dunescape for photos. The trip balances low-impact adventure with a clear window into northern Brazil’s riverine life.
The speedboat journey to Vassouras is about 35–45 minutes, depending on water levels and route conditions.
