If you’re heading to Hawaii’s Big Island and looking for a mix of adventure, natural beauty, and a touch of history, this 4-hour Kealakekua Bay snorkeling tour offers a fantastic choice. Priced at around $153.49 per person, this trip takes you on a lively Zodiac raft along the Kona coast, with plenty of time to swim in vibrant waters and learn about the island’s volcanic past and legendary stories. The guides, like Captain Chuck, are known for their friendliness and wealth of local knowledge, making the experience both fun and educational.
What really stands out is the speedy Zodiac ride — a dynamic way to explore the coastline and sea caves, which you wouldn’t get from a typical glass-bottom boat. The second highlight? The snorkeling in Kealakekua Bay, where the visibility often exceeds 70 feet, offering a mesmerizing view of colorful fish and coral gardens. We also love how the tour combines marine exploration with cultural storytelling, especially at the Captain Cook monument.
One thing to consider is that the raft ride can be bumpy, which might not suit everyone—particularly those with back issues, neck problems, or pregnant women. The tour is also most popular among those interested in lively marine life and adventure rather than a relaxing, slow-paced cruise. If you enjoy energetic, interactive excursions and are comfortable in open water, this trip will hit the mark.
This tour suits travelers who want a small-group feel with personalized attention, or those eager to combine nature, history, and adrenaline-packed rides into one experience. Families with older children, snorkelers, and anyone wanting to see Hawaii’s underwater world in a lively way will find it especially rewarding.

The Experience in Detail

Fascinated by underwater life? Here are other snorkeling spots we've covered in Big Island of Hawaii
Starting Point and Check-In
Your adventure begins at Honokohau Marina, just north of Kailua-Kona, with a well-equipped, family-run check-in office. Here, you can relax in air-conditioned comfort, browse souvenirs, or even pet the friendly golden retriever while waiting to board. This small touch makes the process feel personal and welcoming, setting a friendly tone for the day.
The Zodiac Ride and Coastal Exploration
Once aboard your 24-foot inflatable Zodiac boat, you’ll zip along the coast, passing rocky lava formations and sea caves that are typically inaccessible from shore. The speed and agility of the Zodiac mean you’ll get close to geological features like lava tubes and underwater formations, making the journey as much about scenery as the snorkeling itself.
One reviewer notes, “Captain Marco and co-captain Leila were amazing. We saw whales on the way to the bay which was icing on a great snorkeling experience.” This highlights how lucky you might be to spot marine mammals during the ride, especially in winter when humpbacks migrate here.
The Marine Preserve and Snorkeling
Kealakekua Bay’s Marine Preserve is a highlight, offering some of Hawaii’s clearest waters with visibility often over 70 feet. Expect to see over 100 species of fish in the protected environment, from vivid tropical varieties to sea turtles gliding by. The calm, well-protected waters mean you can snorkel in comfort, drifting over coral gardens teeming with life.
The tour lasts approximately 1.5 hours of snorkeling, during which guides assist with gear, pointing out interesting creatures and coral formations. One guest describes it as “like swimming in an aquarium,” emphasizing how vibrant and plentiful the marine life is.
Historic and Cultural Stops
After snorkeling, the boat heads to the Captain Cook monument, a site shrouded in legend and history. Guides share insights about the European explorer who arrived here in 1778, a story that resonates deeply with Hawaii’s cultural identity. Many reviews mention the guide’s storytelling as a highlight, with one noting, “The story about Captain Cook and his influence he had on the Hawaiian population and maritime community was fascinating.”
The Kealakekua Bay State Historical Park is also part of the package. Since it’s a Marine Sanctuary, the tour offers the best way to see the park without disturbing the environment. The hike down to shore is about 2.5 miles round-trip, but most prefer viewing the area from the boat to protect the delicate reef.
