Snorkeling is a win-win for all visitors to Hawaii. It is easy to learn, inexpensive, and is fun for the whole family! PThe activity doesn’t require much gear and will quickly transport you into a completely different world under the sea. With the longest coastline of all the Hawaiian Islands—the entire island totals 4,038 square miles—and the smallest population, the Big Island boasts perfect conditions for snorkeling. This is especially true on the island’s southern coast near the city of Kona, home to beautiful, pristine waters. For the ultimate snorkeling experience, make your way to the state’s only underwater state park, Kealakekua Bay.
