Why Haleakalā National Park
Haleakalā National Park is an expansive protected area situated on the Hawaiian island of Maui. Spanning 33,265 acres, including a significant wilderness expanse, the park surrounds the dormant Haleakalā Volcano, which last erupted between 1480 and 1600 AD. The name translates from Hawaiian as "house of the sun," referencing a regional legend in which the demigod Maui captured the sun to lengthen daylight. Originally established as a unified park with volcanoes on the island of Hawaiʻi in 1916, it became an independent national park in 1961 and was later designated an International Biosphere Reserve.
The park is divided into two distinct zones: the high-altitude summit area and the coastal Kipahulu region. The summit is accessed via Hawaii State Road 378 along a winding mountain route. Nearby visitor facilities include parking, restrooms, and a visitor center. The central geographic feature is the Haleakalā Crater, a vast erosional valley measuring nearly seven miles across, two miles wide, and 2,600 feet deep. The crater floor features numerous cinder cones and can be explored along designated National Recreation Trails such as the Halemau'u and Sliding Sands routes, which offer backcountry cabins for hikers. Observing sunrises, sunsets, and night skies are popular activities, with local businesses renting binoculars and telescopes for amateur astronomy. Hosmer's Grove presents an unusual forest combining native Hawaiian plants with imported species like Himalayan deodar, Japanese sugi, and Australian eucalyptus.
Haleakalā protects a high number of endangered species. Notable plant life includes the rare Haleakalā silversword and native geraniums, alongside hundreds of other plant species. The park serves as a habitat for native birds like the re-introduced nēnē goose and endemic Hawaiian honeycreepers, including the endangered kiwikiu, akohekohe, and Maui alauahio. In addition, microscopic tardigrades thrive near the summit, and native Kāhuli tree snails inhabit the rainforests.
The separate Kipahulu section lies along Maui's windward coast, reachable only by a curving coastal highway rather than directly from the summit. This lower valley region features the 'Ohe'o gulch, where visitors can hike to Waimoku Falls or swim in freshwater pools along Palikea Stream that host rare native fish. The adjacent upper valley is protected as the Kipahulu Valley Biological Reserve and remains closed to the public to preserve fragile ecosystems.
Elevations within the park range from sea-level coastal areas with a tropical rainforest climate to alpine conditions at the mountain top. Conservation efforts address challenges such as soil erosion and native plant destruction caused by invasive animals, supported by volunteer groups who help maintain trails and restore natural habitats.
