Located in the center of the valley, take time to enjoy the unique museum recounting the history of the Indians which offers objects and records about their traditions. Take the opportunity to admire stuff animals as well as others living under glasses such as tarantulas or snakes that are typically found in the valley.
Of course, when you walk in the valley, pay attention to the noise around you and to the nature! You will maybe get the chance to discover some wild animal species like a giant lizard between two rocks or a little kind of squirrel in the bushes.
