The biggest tourist draw in Villa Tunari is Parque Machía, just across the river from the village. The park is home to a non-profit organization called Inti Wara Yassi, dedicated to caring for sick or previously captive animals. Our visit was a bizarre experience, as interesting as it was troubling, and has become a constant topic of conversation between me and Juergen. Rehabilitating wild animals is usually an inarguably noble endeavor. But with Inti Wara Yassi, we're not so sure.
