Departing from Barreirinhas, access to the circuit typically involves a journey in 4×4 vehicles, followed by a challenging climb up a tall dune, which serves as a gateway to the spectacular views of the lagoons and dunes below. Lagoa Bonita, the focal point of the circuit, is admired for its vast expanse of crystal-clear water, surrounded by fine white sand. The location offers perfect opportunities for swimming and relaxation in an almost surreal setting. Additionally, the sunset viewed from the dune is one of the most magical moments, providing a stunning display of colors in the sky that complements the natural beauty of the surroundings. This visit is a highlight for those seeking a unique and memorable experience in the Lençóis Maranhenses.
