Better than gazing at the Baía da Guanabara is to actually get out upon its blue waters. Saveiro’s Tour (Av. Infante Dom Henrique, Marina da Glória, Glória, tel. 21/2225-6064, www.saveiros.com.br ) rents out all types of sea-worthy vessels as well as water-skis. Those interested in a mini cruise can charter a posh yacht that will take you up and down the coast to destinations such as Búzios , Ilha Grande , Angra dos Reis , and Paraty . A two-hour tour around the Baía da Guanabara costs R$30 per person.
