Haleakalā National Park was named after Haleakalā, a dormant shield volcano that forms more than three quarters of Maui. The park consists of two distinct areas: the summit district high up in the mountains (or rather, volcano), and the Kīpahulu district located along the coast. The landscape (and temperature) difference between the two areas is also very extreme, making for a unique hiking experience in both areas of the park.
