Sliding Sands to Halemau'u Trailhead 11 miles 3000' Trailheads are 6 miles apart. Before hiking in, stop at Park Headquarters to arrange a car drop or ride with other visitors. In the Summit Area, 15-20 minute presentations are given daily in the Summit Building. On selected days, guided hikes are offered by both the park ranger staff and through The Nature Conservancy's adjacent Waikamoi Preserve. Preparing Yourself The 36 miles of trails in the Haleakala wilderness cover a land of sudden contrasts, not only of terrain, but also of topography.
Weather changes rapidly.
You may be exposed to intense sunlight, and then engulfed in thick clouds and heavy rain. Haleakala rises to 10,023 feet, with the average elevation on the valley floor at 6,700 feet. Trails are strenuous at this elevation due to lack of oxygen, and altitude sickness is a concern. Pregnant women and people with heart or respiratory conditions should consult with their doctor before visiting the Park. Hikers must be properly equipped.
