Volcano National Park
Volcano National Park - Volcanoes have created the Hawaiian Island chain. Kilauea and Mauna Loa, two of the world's most active volcanoes, are still adding to the island of Hawaii. Mauna Loa is the most massive mountain on Earth occupying an estimated volume of 20,000 cubic miles. Research at the Hawaiian Volcano Observatory makes Kilauea one of the best understood volcanos in the world. Visitors can experience some of the volcano's power in limited trails at Vocano National Park.
