Hawaii Volcanoes National Park was established in 1916. The area, encompassing 344,812 acres, includes the active volcanoes Kilauea and Mauna Loa. Areas of the park have had to close temporarily when the volcanoes are very active. The park, protecting unusual plants and animals, became a UNESCO World Heritage Site in 1987.
