Do

• Caminata. 2 hours. A walk along a predefined path with a guide to see wildlife (mainly birds). 20 Pesos. 
• Walking. Even if you are short of your own means of transportation, the walk along the road from Carlo Pellegrini to the Natural Park Head Offices across the bridge over the Ibera' is really easy and enjoyable, especially at sunset. Once there, you can take the marked walk inside the small pocket of trees where a colony of howler monkeys lingers. They tend to show if you are silent enough. It is a small walk, but you will get fascinated by everything is around you. Totally free and one of the things you will remember!
