The volcano is located in the Lauca National Park, along with the two higher Pomerape and Parinacota volcanoes; the volcanoes Parinacota, Quisiquisini, Guallatiri and Poquentica form the eastern limit of the Lauca basin. Sometimes Guallatiri is considered to be part of the Nevados de Quimsachata volcanic chain, a long chain of volcanoes.
