Yosemite National Park - General Park Information

Hawai'i Volcanoes National Park displays the results of 70 million years of volcanism, migration, and evolution -- processes that thrust a bare land from the sea and clothed it with unique ecosystems, and a distinct human culture. The park highlights two of the world's most active volcanoes, and offers insights on the birth of the Hawaiian Islands and views of dramatic volcanic landscapes. Hawai'i Volcanoes National Park is a fascinating world of active volcanism, biological diversity, and Hawaiian culture, past and present.

In recognition of its outstanding values, Hawai'i Volcanoes National Park has been designated an International Biosphere Reserve (1980) and Hawai'i's only World Heritage Site (1987).

Established on August 1, 1916, Hawai'i Volcanoes National Park preserves for the enjoyment, education, and inspiration of this and future generations, the significant resources that reflect Hawai'i's geological, biological, and cultural heritage. These resources demonstrate the powerful and awe-inspiring volcanic forces that create new land and the unique adaptations of plants, animals, and people to that land.

The park's 333,086 acres extend from sea level to 13,677' and encompass the summits and rift zones of two of the world's most active volcanoes, Kilauea and Mauna Loa. Kilauea has been in nearly continuous eruption since 1983; Mauna Loa last erupted in 1984. The park's seven ecological zones harbor distinct plant and animal communities--home to many engaging creatures (happyface spiders, carnivorous caterpillars, picture wing flies, etc.) and are a refuge for many endangered species (hawksbill turtle and Hawaiian goose, dark-rumped petrel, hawk, and hoary bat).

Created to preserve the natural setting of Kilauea and Mauna Loa, the park is also a refuge for the islands native plants and animals and a link to its human past. Park managers work to protect the resources and promote understanding and appreciation of the park by visitors.

Superb voyagers, Polynesians from the Marquesas Islands migrated to Hawai`i over 1,600 years ago. Navigating by the sun and stars, reading the winds, currents, and the flight of seabirds, Polynesians sailed across 2,400 miles of open ocean in great double-hulled canoes. They brought with them items essential to their survival and a distinct culture.

Island weather is unpredictable. Visitors should be prepared for rain and wear layers of clothing to ensure their comfort while exploring the park.

Temperature varies by elevation. Weather at Kilauea's summit (4000' elevation) varies daily and may be rainy and chilly any time of the year. At the summit of the volcano, temperatures may be 12 to 15 degrees cooler than at sealevel. The coastal plain at the end of Chain of Craters Road, where lava is entering the ocean, is often hot, dry, and windy with the possibility of passing showers.

Be prepared for all weather conditions. Wear layers of clothing, bring raingear, and wear hiking boots or shoes if you plan to venture out on trails.
