Saveiros Tour operates a cultural boat tour around Guanabara Bay, taking in major sights including Sugar Loaf Mountain, Niterói’s Contemporary Art Museum, the Rio-Niteroi Bridge and Ilha Fiscal. The two-hour trip in a traditional schooner departs daily from the Gloria Marina. Tickets can be bought at the marina.
Other boat companies operate from the docks by Praca XV, offering daily trips to Niterói, Ilha Paquetá and other islands in the bay. There are also day cruises further afield, along the Costa Verde to Angra dos Reis, Ilha Grande and Paraty.
