This is an oasis located on the bed of the Loa River. There is a settlement with crops growing here. There is also a church, an old station and a railway bridge, as well as a museum with an exhibition about the archeology of the area.
It is located on the route that used to comprise the Path of the Inca, so it is therefore pre-Hispanic. Pedro de Valdivia visited in 1540. Here you will find the Quillagua Customs House.
