Baía Norte, or North Bay, is a significant coastal bay on the northern side of Santa Catarina Island, forming part of the greater Florianópolis area in southern Brazil. This sheltered body of saltwater is characterized by its intricate coastline, which includes sandy beaches, mangrove forests, and estuarine environments. The bay is surrounded by a network of Marine Protected Areas and serves as an important ecological zone, supporting a diverse fish assemblage and populations of marine mammals like the Guiana dolphin and Lahille's bottlenose dolphin. For anglers, it offers a mix of inshore and nearshore fishing opportunities, with access from both boat and shore, set against a backdrop of urban convenience and natural beauty.
