The Puʻu Huluhulu Trailhead is the start of the Nāpau Crater Trail along the Mauna Ulu lava shield. The trail leads past four notable craters: in order of distance from the trailhead these are the overgrown Pu’u Huluhulu Cinder Cone, the deep barren chasm of Alae Crater, the flourishing Makaopuhi Crater, and historic Nāpau Crater. Nāpau Crater features a vast overlook to the recently active Pu'u 'Ō'ō cone (which erupted 1983 to 2018) and a cabin which is open for camping reservations.
