included in this portfolio are a number of intriguing lagoons, such as the lagoa de itaipú and lagoa de piratininga. unlike many nother natural attractions of the city, various factors have negatively effected the natural development of these waters, causing them to deteriorate over the last century, with efforts underway to restore their former healthy condition.

lagoa de itaipú, the smaller of the two lagoons, is located in the south zone of the city, just next to the praia de camboinha. this part of niterói is one of the most important tourism areas of the city, and the lagoon is right at the center of the activity, with many visitors coming from far and wide to enjoy the surrounding area, and get a glimpse of the sparkling water.
