There are shows, mainly for kids, in the planetarium on weekends. These are targeted at different age groups so it is essential to check the age the show you plan to attend is for or you may get stuck with one that is totally unsuitable. From Wednesday to Friday the space is also open without shows and there are around 60 hands-on scientific experiments to entertain kids.

Jardim Botânico
Planted in the 1800s, it is both a park and a scientific laboratory. It contains a huge collection of plants from all over the world, not only tropical ones. If you take the bus note that Jardim Botanico is also the name of a neighborhood and the road on which it is found so make sure you go all the way to the entrance. The gardens are well kept and very lush. Not far from the cafe, you are likely to hear swooshing sounds. Look up and you can see small monkeys swinging from tree to tree.
Praia do Leblon
There are two viewpoints in this hike before reaching the final destination of the peak. From the first, you will be able to see Rocinha, which is the largest favela in Latin America, and a clear view of Pedra da Gávea. From the second, you are able to see Serra da Carioca, Gávea, Corcovado (where Christ the Redeemer stands tall), and Pedra Bonita. Once reaching the highest peak of the Morro Dois Irmãos you are able to see all of South Zone (Zona Sul) ranging from Botafogo to Leblon, including a beautiful view of Rodrigo de Freitas Lagoon (Lagoa Rodrigo de Freitas).
Lagoa Rodrigo de Freitas
A large lagoon in the middle of South Zone, with great views to Corcovado and Ipanema and Leblon beaches. You can run, walk, skate or cycle the 7.5 km around this freshwater lake and then retire to your luxurious Ipanema penthouse apartment, or just imagine it! Some have been known to swim in it although pollution levels are very high. Around Lagoa you can rent cycles, swan-shaped pedalos and, on the western side near where the helicopters take off, electric cars for younger kids.
Parque Lage
Public park with walking trails through subtropical forest. A cafe offers drinks and meals. A trail goes up to Corcovado mountain from here. The land was the residence of industrialist Enrique Lage and his wife, singer Gabriella Besanzoni. During the 1920s Lage had the mansion remodeled by Italian architect Mario Vodrel, with interior paintings by Salvador Payols Sabaté. The mansion was notably featured in the 2003 music video for Snoop Dogg's single "Beautiful."
