South

Papakōlea Beach is a Green Sand beach - one of the few in the world. Green is because of a crystal called Olivine (aka peridot in polished gems language). This crystal came from the mouth of a volcano that open up in the ocean. A nearly 6 mile hike (or 4x4 or tour). Hiking was challenging but walking along the ocean was awesome - views, breeze and raw blue Pacific ocean waves all along. Overall, worth visiting, if you have the time (won't fit though if you do a 3 day trip to Big Island).

Just before the access road to this beach is the South Point (a Patel point). This is the southern most land in US (not Florida Keys). This is also the point where the first Hawaiians landed from Polynesia and settled down.
