Fact 1: This national park area is Hawaii's most popular upcountry attraction, and covers the summit area of the larger of the two volcanic mountains that make up the island.
Fact 2: Although a Crater (upper case C), it is, strictly speaking, not a crater (lower case c). It’s so gigantic because it was formed over eons by erosion of the entire volcanic mountain top. Its highest point is 3,055m.
Fact 3: Sunrises and sunsets here are spectacular, as are the dark sky displays at night. If you go for a hike, the thin air means it usually takes twice as long to hike out than it does to hike in.
This is the Haleakala Crater on Maui, Hawaii.
