Nāpau Trail is a 2.5-mile out-and-back foot trail in Hawaiʻi Volcanoes National Park, Hawaii. It climbs 210 ft to a high point of 3,350 ft. Difficulty: easy, from the NPS hiking-rating formula. That is the full hike: the mapped trail line runs 8.58 mi because it also covers connecting trails, so it is not the length of this hike. The figure is for the Park Service's “Maunaulu via Nāpau Trail” hike, which uses this trail.
