You step onto the paved path before dawn, the smell of saltwater riding the cool trade-wind as the crater rim slices the skyline. Headlamps bob like slow-fire lanterns while the trail climbs through kiawe trees and low ohia scrub toward the crater’s rim. At 1.5 miles round trip with roughly 560 feet of elevation gain, the route moves from gentle switchbacks to exposed stairs and a short tunnel before the summit opens to a wide Pacific panorama.
