Question is: Do you need to buy an excursion before you get there? And answer is no.

The National Park is pretty well organized, both in the Argentinean and Brazilian side. Most of the times you can only walk in one direction, and you just can not get lost.

At the visitors center (the place where your taxi will drop you) you will find the desk of  the Tour guides association. You can hire an English speaking guide just for you at a very reasonable price.

Of course, even when you do not need an excursion, joining one can be fun. If you are the kind of traveler that likes to meet people and join a group, we can put you on a full day group excursion that will also include transportation from and to your hotel.
