Preguicas Mouth

The Preguiças River reaches the Atlantic beside the dunes of the Lençóis Maranhenses. Palm-covered banks farther inland give way to mangroves near the mouth, where sand and tidal channels meet the sea. At Caburé, a narrow strip of sand separates the river from the Atlantic; upriver at Vassouras, dunes advance from the shore towards the Preguiças.
