Puʻu Huluhulu kīpuka

Stay on the marked trail; the kīpuka soil and remnant native vegetation are fragile. Do not collect plants of any kind — māmane and naio support endangered native birds, including the palila honeycreeper. Pack out trash. No fires, no smoking; the dry vegetation is fire-vulnerable. The grassy area at the trailhead was the central organizing site of the 2019 TMT protests; if you encounter Hawaiian protocol or ceremony, give it space and quiet. Do not photograph anyone in protocol. The site is sacred ground for the protest movement and remains an active gathering place.
