Hawaii trails · Kalalau Trail
A 10.2-mile out-and-back in Hawaii, with 782 ft of climbing. Reaches Hoʻoleʻa Falls and other beach/viewpoint/waterfall destinations.
The climbing leans toward the first third: 48% of the ascent falls between mile 0.0 and mile 3.4. It gives back about 3,071 ft along the way, so it rolls rather than climbing steadily.
