Departure from Barreirinhas in a 4×4 vehicle that will take us to one of the ferries to cross the Preguiças River that gives access to the Lençóis Maranhenses National Park (PNLM).

The trail journey lasts an average of 35 minutes. At the foot of the dunes, we get out of the vehicle and begin an approximately 15-minute walk to the Blue Lagoon, or rather the station's lagoon, where we will enjoy a delicious swim. Continuing on foot, a walk of approximately 20 minutes, free time for sunbathing and swimming in the lake.

The Lagoa Bonita Circuit trail route lasts an average of 1 hour, longer than the Lagoa Azul Circuit, but no less fantastic. In front of the Dunes there are support points where cars will be parked, together with a guide we will start the climb to access Lagoa Bonita, right at the beginning of the walk. After this climb your tiredness will no longer exist, as you will be impressed by so much beauty. Free time for sunbathing and swimming in the lake.
