The Hawaiian name for Big Islandʻs Green Sand Beach
Papakolea is one of only four green sand beaches in the world. The distinctive color comes from olivine crystals (a semi-precious mineral) eroded from the surrounding Puʻu Mahana cinder cone, a remnant of the Mauna Loa volcano. The olivine is heavier than other sand grains and concentrates on the beach.
The beach sits in a remote area of the Kaʻu coast with no development, streams, or storm drains nearby. Water quality is generally very good. The main concern is the strong currents and waves that make swimming risky, not bacteria or contamination.
The beach is approximately 2.5 miles from the South Point parking area. The hike is across open, windy terrain with no shade. Some locals offer rides in 4x4 vehicles for a fee. The trail down to the beach is steep. Bring water, sunscreen, and sturdy shoes.
