Snorkel Kona’s vibrant reefs near Captain Cook Monument, spot marine life, and cruise past sea caves and lava tubes on a four-hour trip.

About this tour

Explore Kona’s clear coastal waters on a two-reef snorkeling trip to Captain Cook Monument and Puuhonua O Honaunau National Historic Park. With a knowledgeable crew leading the way, Kona two-reef snorkeling pairs colorful marine life with dramatic Big Island scenery.

Snorkel among more than 100 varieties of tropical fish, and keep watch for reef sharks and sea turtles. Between stops, cruise along the rugged coastline past sea caves and lava tubes while the crew shares Hawaiian history. Dolphins may appear along the route, and humpback whales can be seen during their seasonal migration. Snacks, fruit, juice, bottled water, and snorkeling gear are provided for your time on the water.

The four-hour Kona two-reef snorkel trip departs from Keauhou Bay after check-in at Keauhou Shopping Center. Bring a towel, cover-up, and reef-safe sunscreen, then get ready to discover the reefs and coastline of the Kona coast.
