Porto Alegre
Geography

The city of Porto Alegre is located at the northern end of the large coastal lagoon, Lagoa dos Patos in southeastern Brazil. The city lies on the east bank of the mouth of the Rio Guaiba, the estuary of which forms the enormous freshwater lagoon, Lagoa dos Patos. Also joining the Guaíba at Porto Alegre are the Jacuí River, the Sinos River, the Gravataí River and the Caí River, all tributaries of Guaíba just before it empties into Lagoa dos Patos.

Porto Alegre has a long coastline on the Guaíba Lake, and its topography is punctuated by 40 hills. In the lake, a vast body of water, a maze of islands facing the city creates an archipelago where a unique ecosystem gives shelter to abundant wildlife. The city area concentrates 28% of the native flora of Rio Grande do Sul, with 9,288 species. Among these, there are many trees which are vestiges of the Atlantic Forest. Fauna are also diversified, especially in the islands and hills. The Portoalegrense environs include many parks, squares and wooded streets.
