The Bertioga county lies on the northern coast of São Paulo, 100 km from the city of São Paulo, and still possess about 60% of its preserved natural area known as Atlantic Rainforest, with the main rivers: Itapanhaú River its main tributary on its left bank the beautiful Jaguareguava River (23 ° 49’47 .90 “S 46 º 09’48 .20″); Guaratuba River (23 ° 45’04 .22 “S 45 º 53’41 .57″) and the Itaguaré River (23 ° 46’39 .23 “S 45 ° 58 ’10:15 “). The latter is the lesser, without relevant tributaries, but preserved very well.
These three rivers form undoubtedly the major basins of the municipality, and all have a similar feature: comes snaking through the sandbank formations from the mountain to the bottom, forming a large bird habitat in the marsh also seen in its two margins.
