Welcome to Summit Area
The summit is an unabashed showstopper. Often referred to as the world’s largest dormant volcano, the floor of Haleakalā is a colossal 7.5 miles wide, 2.5 miles long and 3000ft deep – nearly as large as Manhattan. In its prime, Haleakalā reached a height of 12,000ft before water erosion carved out two large river valleys that eventually merged to form Haleakalā crater. Technically, as geologists like to point out, it’s not a true ‘crater,’ but to sightseers that’s all nitpicking. Valley or crater, it’s a phenomenal sight like no other in the US national park system.
