Crater Rim Trail

Starting from the Haleakala Visitor Center at nearly 10,000 feet, this out-and-back route traces the knife-edge rim of one of the most otherworldly landscapes in the national park system. The trail is well-defined but rocky — volcanic cinder and uneven lava rock demand your attention underfoot. Within minutes, the crater opens up below you like a Martian basin, with cinder cones rising from the floor in shades of rust, charcoal, and burnt sienna. On clear days, you can see across the central valley to the West Maui Mountains and sometimes pick out the Big Island on the horizon. The elevation gain is gentle enough that most people barely notice it, but the altitude will remind you it's there through your lungs. This is the trail for anyone who wants the iconic Haleakala crater view without committing to a full-day descent into the basin.
