"O rio Preguiças fica localizado no estado do Maranhão e faz parte do complexo dos Lençóis Maranhenses, nasce no município de Santana do Maranhão, numa altitude de cerca de 120 metros e percorre quase 135 km de extensão até chegar à sua foz, no Oceano Atlântico no município de Barreirinhas
A origem do nome do rio seria em virtude da presença de muitos bichos-preguiças que habitavam as matas das margens do rio, mas alguns dizem que o nome se deve ao fato de que o rio tem águas mansas e tranquilas.
O clima da região é tropical, muito quente e úmido, com precipitações distribuídas em dois períodos sazonais, com chuvas de janeiro a julho e uma estação seca de agosto a dezembro.
As temperaturas médias da região ficam entre 26 e 27º C, com temperaturas máximas que podem alcançar 38ºC, enquanto a precipitação anual situa-se entre 1.600 e 1.800 mm.
A vegetação da região é caracterizada pela presença do cerrado e mata ciliar, além de dunas, restingas e mangues na região de sua foz.
Os passeios de barcos e lanchas pelo rio são uma importante atração turística da região dos Lençóis Maranhenses, com destaque para o Parque Nacional dos Lençóis, Pequenos Lençóis, Farol do Mandacarú, Caburé e Atins."

The Rio Preguiças River Tour Circuit
Vassouras, often the first stop, is famous for its playful monkeys that inhabit the small dunes bordering the river. It's a lively introduction to the area's wildlife and the unique environment where the dunes meet the water. Following Vassouras, the tour proceeds to Mandacaru, a small village dominated by its iconic lighthouse. Climbing to the top of the Farol de Preguiças is a highlight, offering breathtaking 360-degree views of the vast dune fields, the winding river, and the distant Atlantic Ocean.
Finally, the circuit usually concludes at Caburé, a narrow strip of land situated between the Rio Preguiças and the Atlantic Ocean. This unique geographical feature provides a stunning contrast of environments. Here, visitors can enjoy fresh seafood at local restaurants, relax on the beach, and soak in the serene atmosphere. Some tours may extend further to Atins, a charming village known for its kitesurfing and delicious shrimp dishes, offering a more extended exploration of the region.
Exploring the Communities Along the River
Mandacaru is home to the prominent lighthouse, a crucial landmark for navigation and a major tourist attraction. The village itself is small and offers local crafts and a taste of rural life. The climb to the lighthouse is a must-do for the incredible vistas it provides. Caburé, situated on a peninsula, offers a different experience with its beaches and the unique sensation of being between the river and the sea. It's a popular spot for lunch and relaxation.
Further along, Atins is a growing hub, particularly popular with kitesurfers and foodies, famous for its shrimp dishes. These communities, while distinct, are all connected by the river and share a deep connection to the natural environment. Experiencing these stops provides a richer understanding of the Lençóis Maranhenses beyond just the famous dunes.
Best Time to Visit and Weather Considerations
For the most iconic views of the Lençóis Maranhenses National Park, with its full lagoons, the best time to visit is between May and September. During these months, the rainfall has replenished the lagoons, creating the stunning turquoise and emerald pools amidst the white sand dunes. This period is considered peak season due to the ideal conditions for exploring the park.
However, if your primary interest is exploring the Rio Preguiças itself and enjoying the river tours without the peak crowds, the dry season (August to December) can be an excellent choice. While the lagoons might be less full, the landscapes are still dramatic, and the weather is generally more stable for boat excursions. This period offers a good balance of pleasant weather and manageable crowds.
