Big Island Snorkeling, Diving & Watersports

The Kona coast of Hawaii's Big Island is rich with snorkeling areas. Considered one of Hawaii's finest snorkeling spots, Kealakekua Bay is a secluded marine sanctuary abundant with marine life, coral reefs, calm water and 100-ft visibility. To get there, travel south on Queen Kaahumanu Highway (HI-11). Turn right on Napoopoo Road. Turn right on Puuhonua Road to Kealakekua Bay State Historical Park. About 40 minutes south of Kailua-Kona.

Kahalu’u Beach Park is one of the best snorkeling spots on the Big Island. It is fed by a fresh water spring, up to 10 million gallons per day. These waters are almost always calm, with colorful corals, rock formations, and 100+ species of fish. Swim with huge schools of colorful fish and green sea turtles in these protected waters; don't forget your underwater camera! The north end of the beach is where the waves break and is best for body boarding and surfing. Check the water conditions; when ocean swells are present, the water can be murky.

There are many, many spots with incredible visibility—up to 100 feet—along the Kona Coast (even right off the Mauna Lani and Mauna Kea resorts). There are also two incredible swimming and snorkeling spots on the southeast side. The first, Champagne Pond, is a calm ocean cove heated by the volcano. The water is also slightly effervescent, but that doesn't seem to bother the abundant fish and turtles. It's accessed from a dirt road off Highway 132 (heading toward Kapoho from Hilo). At Kapoho "Wai Opae" Tide Pools, a collection of spring-fed brackish pools, beginners will feel safe and even the most jaded snorkelers will be impressed by the coral and fish. To reach it, drive to Kapoho at the end of Highway 132, then south on Highway 137 to Kapoho Kai Road.

Or take a snorkeling tour with one of several dive and snorkeling companies and explore the waters of Hawaii's Big Island with an experienced guide. The possibilities are endless.

Note: Please be aware of a few guidelines when you’re in the ocean: 

• Approaching dolphins or sea turtles is illegal and subject to fines. 
• Be considerate of the coral – stepping on it or touching it kills it.
• Never pick up a shell underwater. There may be someone living in it – and some sea life is poisonous!

Stay safe – be aware of what’s going on around you, and never turn your back on the ocean. You don’t want to be knocked down by a wave onto sharp coral or lava rocks when entering or exiting the water.
