The circuit of the Blue Lagoon is among the most famous of the Maranhenses Lençóis. The tour departs from Barreirinhas and has a half-day duration. When it comes to the Circuit of the Blue Lagoon, the same lagoons are not always included. The most common itinerary includes a visit to Lagoa da Preguiça, Lagoa da Esmeralda, Lagoa da Paz, Lagoa do Peixe and, as it could not be missed, the Lagoa Azul. It is worth noting, however, that this route is not mandatory.
