For some of the best snorkeling on the Big Island, visit the protected waters of Kealakekua Bay.
This remote area is also popular with hikers, who might come across the ruins of ancient temples and villages on their travels.
Dolphins frolic in the bay, and the shore is dotted with the white obelisk commemorating the death of Captain James Cook here in 1779.
Kealakekua Bay is surrounded by Kealakekua Bay State Historical Park on the western Kona coast.
The easiest way to get here is to either paddle in by kayak or take an organized tour.
