Tips
This lava tube is just inland from the black sand beaches typical of this area on the west coast of the big island. Lava tubes are created by the volcanic process and can be made two ways. One way is when the surface of lava cools faster, and the other way is sequential lava flows, with newer flows going underneath the older flows and creating cavities by inflation.
