“Please do not waste your time attempting to reach this beach by foot. The view is not worth the hours it would take and the beach is hardly green. A better description of the sand would be black with [brown][…]If you have a sadistic personality disorder and are looking forward to 3 hours of black and dry lava fields then pack plenty of water, sun screen and a gun to blow your brains.”
