Lauca National Park (Parque Nacional Lauca) covers an area of 1,300 square kilometers and consists largely of high plains and mountain ranges, many of the latter comprised of large volcanoes.Highlights include hiking around its many pristine mountain lakes, most notably Cotacotani and Chungara, which reflect the scenery around them to stunning effect.
The park also features a number of important archaeological sites, as well as evidence of the early European settlers who left their mark in the region's many fine old colonial churches and buildings.
It's also especially popular for bird-watchers and is home to more than 140 species.
