Guanacaste is a region where the volcanic activity is present in the Cordillera Volcanica de Guanacaste, or the Guanacaste Volcano Range. The Guanacaste Volcano Range is the largest and longest volcanic range in Costa Rica, including volcanoes like the Rincon de la Vieja volcano, the Miravalles Volcano, the Tenorio Volcano, and other lesser known volcanoes like the Cacao and the Orosi. The Guanacaste Volcano Range can be seen from almost all of Guanacaste, especially from the lowlands. The Guanacaste Volcanoes also separate the tropical dry climate from the humid tropical rainy climate that arises from the Caribbean.
