Papakōlea Green Sand Beach

Do not remove olivine sand. State and federal ordinances against beach-material removal apply, and the source is finite — the small beach exists because of a slow erosion process, and a hundred visitors each pocketing a handful is a measurable loss. The hike across open lava field is five miles round trip with no shade and no water; bring two liters per person. Local 4WD shuttles drive the access road for a fee; the practice is informal and rental cars are prohibited. The walk is the recommended approach. The descent to the beach is a steep eroded scramble; sturdy shoes required.
