A flat ~2.8 mile hike out to the beach. Have you ever been to a green sand beach?
Papakolea Beach aka Green Sand Beach is situated in a bay cut into a side of a cinder cone that erupted thousands of years ago. The green sand is created by a silicate deposit (mineral deposit) of lava called, which stays on this beach because it is heavier than the other, lighter components of the lava.
To get to the beach, the 2.8 mile (5.6 roundtrip) hike out there isn't too bad. The path is relatively flat until you climb down onto the beach. The only thing to keep in mind is that the hike is really exposed so if it's windy, the sand will be blowing around a bit. Once you get there, enjoy the beach and go for a swim if the waves aren't too big or you're a comfortable ocean swimmer. You may also want to grab a coconut or a cold one from the local vendor before heading out to the beach.
