Haleakalā National Park is an American national park located on the island of Maui in the state of Hawaii. Named after Haleakalā, a dormant volcano within its boundaries, the park covers an area of 33,265 acres (52.0 sq mi; 134.6 km2), of which 24,719 acres (38.6 sq mi; 100.0 km2) is a wilderness area.
The park is known for its volcanic features, its long scenic drive with numerous overlooks, and the unusually clear views of the night sky available. Haleakalā is one of the best places in the United States for amateur astronomy. Visitors frequently come to the summit of the volcano to watch the sunrise and/or sunset.
Six designated sites are located in an open, grassy area near the forest and shrubland of Hosmer Grove. Each site has a picnic table, grill, and access to potable water. Campers who obtain a reservation to camp at Hosmer Grove campground also receive a reservation to view sunrise the morning after camping. There are two primitive wilderness tent camping areas which are accessible only by trail, Hōlua and Palikū. Reservations are required for both campsites through www.recreation.gov.
