Papakolea Green Sand Beach at Mahana Bay is among the truly magical Hawaii beaches. Near South Point at the southern tip of the Big Island, reaching Mahana Bay is a bit of a trek but you will be rewarded for your efforts, with breathtaking scenery and wide-open vistas. The only green sand beach in Hawaii and one of only two in the entire world, Papakolea is a real marvel.
The green sand at Papakolea Beach comes from olivine crystals that erode over time as the ocean does its work on the basalt lava flow. There is such a high concentration of the mineral olivine in the lava found in this area that the entire beach appears green. This and nearby Punalu’u Black Sand Beach are two of the most unique Hawaii beaches you will encounter anywhere.
The hike to Papakolea Beach is just under 2.5 miles (four kilometers) each way, across wide-open, dusty coastal pasturelands. Wear plenty of sunscreen and bring lots of water. Depending on when you go, it may feel like a pleasant stroll, or more like a death-march if the sun is scorching hot and the wind is pummeling dust in your face.
We try to go early in the day before the wind really picks up, with enough time to be able to enjoy lunch on the beach. Either way, take your time. Hike deliberately. There are rewards all along the way, with more to see than simply the Green Sand Beach itself at your destination. This hike can be a real treat and our recommendation is to slow down, do a little exploring and discover all the hidden treasures along the way.
One of the treats in hiking close to the coastline is occasional pockets of shimmering green sand, deposited where water has receded from the tide pools. In places the sand has a glassy gem-like quality. It is so vibrantly green it could almost be the remains of an undersea emerald city that has washed ashore.
Resist the temptation to pocket any of the beautiful green sand as a Big Island souvenir. Not only is the supply limited, but the volcano goddess Pele has been known to frown upon visitors who remove green or black sand from her beaches!
The coastline along here is raw and untamed. Waves crash along the jagged shoreline and send sea spray rocketing skyward. Periodically you will come across evidence of ancient Hawaiian civilization in the remains of the rock structures along the coast.
Even with all the branches in the road that seem to ramble every which way along the path to Green Sand Beach, it’s not easy to get lost on this hike. Just keep the coastline on your right and eventually you end up at the beach. Papakolea lies at the bottom of a large lava bowl carved out of the coastline. The trail to the bottom begins behind the beach, with a steep descent that is often slippery. Before you venture down, check the surf and make sure the waves aren’t crashing clear up to the top of the beach.
The reward for your efforts is breathtaking. While Papakolea beach itself is relatively small, the scenery is stunning with the turquoise blue ocean, grey cliffs and green sand against a blue sky. Use extreme caution if you go into the water. The ocean adjacent to Mahana Bay is unprotected and waves can be severe. People do swim here. We generally choose not to, unless it’s super calm. It’s just too exposed, and the undertow is fierce during even moderate surf. There are plenty of other great Hawaii beaches that make for better swimming!
There are frequently a handful of locals hanging out in the parking area with their big four-wheel drive trucks who will offer to shuttle visitors to the beach for a small “gratuity.” If you are not up for the hike, it might be wise to use one of them rather than risk trashing your own vehicle.
To reach Papakolea Green Sand Beach, turn onto South Point Road between the 69 and 70 mile markers on Highway 11. At about 4 miles, take the right fork. As you near the coastline at about 8 miles, take the left fork to the end of the road. The road is paved, but is very narrow and in disrepair.
