Haleakala crater is one of the many exotic things you will find in Hawaii, which is much more than a land of beaches and hula girls. Haleakala "Crater," sitting at 10,023 feet above sea level, is the deep pit at the top of one of the dormant volcanoes that formed Maui. It is not a true crater since it was formed by erosion, but it has the shape of a huge crater, it looks like something you would find on the moon, and the name has stuck for many years.
