Brazil's second biggest bay. Guanabara Bay is huge, covering 384 square kilometres with a coastline that winds for 143 kilometres around the cities of Rio de Janeiro, Niterói, and others.

Cities dot its shores. Rio de Janeiro and Duque de Caxias sit on the western side, while Niterói and São Gonçalo nestle on the eastern shore, making it one of Brazil's most important urban areas.

Gateway to the ocean. This oceanic bay connects to the Atlantic Ocean and serves as a major port and heart of the Rio de Janeiro region, handling ships and boats constantly.

Surrounded by beauty. Eight different cities and municipalities ring the bay's shores, creating a mix of bustling urban areas, beaches, and natural landscapes all around the water.
