The Haleakala road climbs through plantations and ranchland from Kahului
Harbor and Kahului Airport to the park entrance at an elevation of 6,740
feet. The distance by the shortest route is thirty miles. The highway
continues eleven miles further to the Park Observatory on the western
rim of Haleakala Crater and to the 10,025-foot summit. No bus service
exists, but taxis and U-drive cars are hired at the airport and in the
towns of Kahului and Wailuku. The sole access into the crater is over
good trails for travel on foot or by horse.
