Parque Nacional Lauca is the northernmost chilean national park. It extends from the high andean steppe all the way to the Altiplano including various peaks of more then 6.000m of altitude. The most prominent mountains are the twin volcanoes Parinacota and Pomerape of the Payachata volcanic group. Surrounding those two snow covered cones lie the Lagunas Chungará and Cotacotani, which are home to an abundance of bird species. To the east, Parque Nacional Lauca borders with the bolivian Parque Nacional Sajama – home of Bolivias highest mountain.
