Some good collection of snakes and educational material on vaccines and epidemics. Total impression was that they could do more to catch the interest of the visitor. Felt sorry for the monkeys.

I would say this is a must while you visit são paulo specially with kids. There is a nice educational museum and on some hours of the day they show you how they take venom of the snakes

I went because it has good reviews on tripadvisor, but that was deceptive. First of all, they have monkeys trapped in cages which are alone. It says that they used to be used for experiments, although it seems to me they are probably still experimenting on them. And if not, why keep them there? They are set in separate small... More

This place is awesome to get to know all about snakes. It's intriguing and very, very curious. This institute is famous and highly respected as a scientific example and also is responsible for the production of almost all brazilian antidotes for snake bites.

the diversity of reptile life is amazing, nice place to visit.

It could be FANTASTIC but its a goverment run institution... I love the park, the snakes and spiders and the history of the institute, wich had a world standing in the discovery and production of anti venom. I found it a bit run down and lost of the signs are missing. But it's still worth the visit!

For how long it took the driver to get there in the traffic I would give it a pass. Not much to see.

A biological institute which speciallity is snakes and poisonous animals. Children will love it, as long as you do not throw them at the snake pit (just kidding). Nice park, full of shadow for promenade. The problem is the lack of car parking.
