Know Before You Go
Close to Butantã metro station (on the yellow line).
The deadly Jararaca pit vipers kept in the first of the three outdoor snake enclosures can be hard to see for much of the day. If you are keen to see them in all their sinister serpentine beauty check out the enclosure just before sunset when they begin to become much more lively. You won't be disappointed.
Be sure to see the famous golden lanceheads in the snake house as well as their less famous relative the Alcatraz viper (the institute is the only place in the world where this species can be seen outside of its natural habitat-the Alcatrazes Islands).
