Summit District
Haleakalā Crater, despite its name, is an erosional valley dotted with large cinder cones and other volcanic features. Many visitors come to the summit to watch the sunrise over the rim, then head onto the trails. Hiking ranges from a 0.5-mile self-guided nature walk at Hosmer Grove, a popular place to spot native forest birds, to the Sliding Sands Trail, which drops steeply into the valley past cinder cones, backcountry camps and cabins. Across more than 30 miles of trails, you can cross the cinder desert, where the volcano's geology is on display, or walk through native shrubland home to endemic plants and forest birds. The Haleakalā Visitor Center sits near the summit with parking and restrooms. Expect the high elevation to make the trails strenuous.
