What You Can Expect

Zodiac Raft and Snorkel Adventure

Zodiac Raft and Snorkel Adventure

Teeming with vibrant marine life, the protected waters of Kealakekua Bay off the Kona coast make for an ideal snorkeling destination. Begin your adventure at Honokohau Marina just north of Kailua-Kona, where you’ll meet your captain and climb aboard a 24-foot (7-meter) inflatable Zodiac raft — an agile, rigid-hull vessel used by the US Coast Guard and Navy SEALs.

As you cruise south along the beautiful Kona coastline, learn about the island’s fascinating history as your guide shares local facts and legends. See the Captain Cook monument, where the first European made contact with Hawaii, and keep an eye out for local marine life including spinner dolphins and humpback whales (during winter). Explore the Big Island’s volcanic history as your raft darts in and out of sea caves and past rocky lava tubes. 

Slip on a provided snorkeling mask and fins and plunge into the warm, clear water to swim among schools of electric-colored fish and intricate coral gardens. After approximately 1.5 hours of snorkeling, climb back aboard the raft and refuel with a fresh Hawaiian snack and beverages (or picnic-style lunch on the 10 am departure).   

Continue along the spectacular coastline back to the marina, where your 4- to 5-hour adventure concludes. 

Please note: Due to the bumpy nature of the raft ride, this tour is not recommended for those with back or neck problems, or pregnant women.

Rick and Buddha were our guides, and are skilled, intimately knowledgable, and ridiculously funny. We saw things the other boats missed like resting baby sharks and Rick made sure we got to Captain Cook before the ret of the boats so we had unfettered access and perfectly transparent water. The people in our boat were clearly having a LOT more fun than the other tours as well. This was our first activity of the vacation and was a great kickoff. The Zodiac is enormous fun, like a motorcycle!

This was the first thing we did when we arrived in Hawaii last week. Our captain was professional, knowledgeable about the area and he was fun to be with. His assistant was also a blast to be around. Our trip started out quickly with a couple of stops to be among dolphins who were returning from feeding all night. We attempted to find some whales but nature being fickle didn't produce any for us to see. We then proceeded to a very nice quiet area to do some snorkeling. The water was crystal clear and protected from the wind and waves further out.

Riding on the boat is fun especially out in the open ocean. Lots of bumps and bounces. Our captain was nice enough to stop several times to let everyone take a break and to release their death grip on the safety handles. :

Just a word to the wise, if you have back or neck troubles I don't recommend this mostly due to the bumps and how the boat is unforgiving on passing that feeling onto the passengers. I do, however, recommend this to anyone who can get down there and experience this adventure. It was a blast and even though I have already done it once, I will do it again during the next visit.

Our guides, Maria and Liz, were great. So friendly and really knew the water and coast well. The trip is well worth the cost and the time. Snorkling at Captain Cook's was so beautiful. Definitely recommend a lot of sunscreen - a lot and reapplying often. The guides talk about it a lot and my family wishes we applied even more. If we ever come back to the Big Island, we will do this adventure again.
