One of the more uniquely Chilean forms of transportation is the colectivos. You can find them around Villarrica. Essentially a systems of taxi drivers that drive a set route all day car pooling riders. One of the better deals, especially in more rural areas where taxis are limited and expensive relative to the price of a taxi in Santiago. Jumping in a colectivo can also be a great source of information, as the riders and drivers pool there knowledge of the area to answer whatever question you might have.
