One of Recreio's hidden wonders, the Chico Mendes eco-space has more in common with a wildlife sanctuary than somewhere to go and fly a kite. Jacaré (caiman), snakes, rare butterflies and monkeys can all be safely seen in their natural habitats, while 5km of straightforward hiking trails get you closer to the flora and fauna. An observatory tower offers spectacular views across the swamps and lagoons, and the facilities are mostly in good condition.
