Ready to be amazed by the unique sands that cover this Big Island paradise. Papakolea Beach is a sight to behold, as it is one of only four green sand beaches known to exist. You'll have to travel nearly 3 miles down from the parking lot to reach the beach, which is located south of the Mauna Loa volcano on Mahana Bay. Though the hike can be difficult, the beautiful views is well worth the effort. You'll find bright green olivine sand, as well as stunning gray cliffs and beautiful blue water, deposited during Mauna Loa eruptions. Check out neighboring sights like Punalu'u Beach and Kula Kai Caverns after a few hours of sunbathing (swimming is not recommended owing to the strong undertow). Although there are few lodging alternatives in the near area, the cities of Waimea, Kailua-Kona, and Hilo have dozens of excellent hotels.
