Cruising the Guanabara Bay in Rio

Get set to enjoy the famous icons of Rio de Janeiro…from the water!  Take in Rio’s most iconic sites and stunning coastline as you cruise around Guanabara Bay, the second largest bay in Brazil.  From the bay you will view Sugarloaf Mountain, Christ the Redeemer Statue, and the white sands of Copacabana Beach.

From this unique perspective, you will also view the beaches of Niteroi, fortified walls of the seafront Santa Cruz de Barra fortress built in 1555, and admire the hillside fortress of São João.

The harbor of Rio de Janeiro, surrounded by majestic granite mountains, was named one of the seven natural wonders of the world.

The cities of Rio de Janeiro and Duque de Caxias are located on the western shore of Guanabara Bay, while on its eastern shore lies the cities of Niterói and São Gonçalo.  Four other municipalities also line its shores.

The bay is 19 miles long and 17 miles wide at its maximum, and almost one mile wide at its mouth to the Atlantic Ocean.  The mouth is flanked on its eastern tip by Parrot’s Peak and Santa Cruz fortress and its western tip by Sugar Loaf and São João fortress.  In the entrance is the island-fort of Laje, temporary site of a Huguenot settlement in 1555. 

Guanabara Bay

The Portuguese were the first Europeans to arrive on its shores on 1 January 1502.  According to some historians, the bay was first called “Ria de Janeiro,” or January Sound.  But it seems there was some confusion between “ria,” meaning bay or sound, and “rio,” meaning river, as some thought the bay was the mouth to a large river.  In the confusion, the name became Rio de Janeiro, and the city was named after the bay.

The name Guanabara comes from the Tupi language and translates “bosom of the sea.” 

More than 130 islands dot the bay, which is crossed by the 8.26-mile long Rio-NiteróiBridge.  Numerous smaller bridges connect the mainland to the two largest islands of Fundão and Governador.
