Papakolea (Green Sands Beach)

Experienced hikers might try the 4-mile coastal trek to this amazing beach containing olivine crystals from the cinder cone behind. But be aware: there are no facilities or water (or shade) available. And be very cautious if you venture into the ocean. Only go in if the water is calm and you are a good swimmer. During high surf, there is a strong rip current. Also, be sure to lock your car and take valuables with you; the rather remote parking lot is unattended.
