The United States Congress designated the Hawaii Volcanoes Wilderness (map
) in 1978 and it now has a total of 130,790 acres
All of this wilderness is located in Hawaii
and is managed by the National Park Service.
The Big Island of Hawaii is home to Hawai'i Volcanoes Wilderness and its volcanoes. This Wilderness is fragmented into four areas lying within Hawai'i Volcanoes National Park. In order to protect humans from hazardous fumes, the areas surrounding erupting vents are closed to travel. The northwestern extension of the Wilderness holds Mauna Loa. To the southwest, a large chunk of this Wilderness includes several miles of coastline. More than 150 miles of trail crisscross the park, mostly within Wilderness. The Ka'aha Trail leads hikers down the fault scarps of Hilina Pali to the ocean. The Napau Trail crosses lava from the Mauna Ulu Lava Shield (1969-1974) and follows above the path of magma flowing to the vent on Kilauea's east rift.
