Park
The Quinta da Boa Vista is a public park of great historical importance located in the São Cristóvão neighbourhood, in the North zone of the city of Rio de Janeiro, Brazil. The park was part of the gardens of the São Cristóvão Palace, the residence of the King of Portugal and then the Emperors of Brazil in the 19th century and the home of the Zoological Garden of Rio de Janeiro, with over 2000 species of animals. The building of the old palace hosted the National Museum, with collections on natural history, ethnology and archaeology.

If you won't be making it to the Amazon or the Pantanal, this is a good place to see some of Brazil's more exotic creatures.
Estádio do Maracanã
Once the world's highest capacity football venue, it was able to hold nearly 200,000 people. In modern times, the capacity has been reduced because of safety considerations, and the introduction of seating for all fans. It is undergoing renovation, to expand it to hold 80,000. The matches of Rio's football clubs like Flamengo or Fluminense are usually far from full, so go along and watch a game. There is also a Soccer Museum inside.
Museu de Astronomia e Ciências Afins (MAST)
Also has an observatory.
