Visit Arica and Parinacota
A popular tourist destination in Arica and Parinacota is Poconchile National Reserve which is home to hundreds of native species of plants and animals. Another noteworthy location to visit is Lauca National Park which holds some of the world's highest permanent lakes at an altitude of over 3,000 meters.
In terms of history, Arica was once part of Bolivia until it was taken by Chile during The War Of The Pacific (1879-1884). From then on it became part of Chile for good - as confirmed by the Treaty Of Peace And Friendship signed between Bolivia and Chile in 1904.
