What You Can Expect

Kealakekua Bay Snorkeling Tour With Optional Honaunau Bay

South Kona Sea Cave and Snorkeling

This Big Island snorkeling tour begins at Keauhou Bay about 15 minutes south of Kona. After checking in you’ll be fitted with snorkeling gear and listen in on a safety briefing, before venturing out towards Kealakekua Bay in a rigid, inflatable hull raft. The waters here at this marine reserve are known for their exceptional clarity, and are sheltered enough for first-time snorkelers to feel comfortable entering the water. 

This is the spot where Captain Cook first landed on the Big Island of Hawaii — and ultimately met his untimely end in a skirmish with local Hawaiians. While a monument stands in honor of Cook and commemorates his time in the islands, the bay is best known today for its tropical fish and abundance of colorful coral.

While cruising between shore and Kealakekua Bay, scan the horizon for bottlenose dolphins that sometimes splash on the surface, or search for pods of spinner dolphins that leap and jump in the air. In winter, there’s a good chance you’ll spot humpback whales either breaching or spouting offshore, and it’s also possible to find pilot whales that live in these waters year-round.

Depending upon the snorkeling tour you choose, you’ll also visit Honaunau Bay and sea caves along the coastline, which can only be accessed by smaller rafts that are narrow and easy to maneuver. All tours include water, snacks and an informative captain and guide. Just just bring a hat, towel, swimsuit and a healthy sense of adventure. Details of different tour options are in the Itinerary.

3 great snorkeling spots. Knowledgeable guide and boat captain who shared fun facts about the island, its history and the land formations. The 5 hour tour is perfect. We even got to see the dolphins spinning and flipping in the air. Captain Jenna made this a fun adventure.

We had three stops to snorkel. The first two were OK, the third stop was GREAT. The boat ride included informational stops at sea caves and various formations with our guide providing history and background information. A wide variety of fish were seen during snorkeling, a manta ray about 10' was posing for pictures at one stop. On the ride back, Spinner dolphins came to show off their acrobatic skills and were jumping and spinning all around us. The boat was stopped so we could enjoy this natural show. Rather than stay on schedule, we hung out with the dolphins and got back a bit later than scheduled. If you enjoy snorkeling, you will have a great experience with this tour.

It was an awesome cruise. It would have been nice if Viator would have give us the name, address and phone number of the company that was doing the snorkeling! Had to call 3 companies to find this information!

Very good outing. They were helpful for beginners and the bay was gorgeous and clear for snorkeling! We saw so many beautiful fish. We also saw lots of waves crashing against the volcanic shoreline. All beautiful.


5 star rating: Highly Recommended February 2017

This snorkeling tour was AWESOME!!! Our captain was Laura and deck hand was Kai. Both were so GREAT. Really nice and super helpful. Laura was very, very knowledgeable about the area and marine life. Small boat and very bumpy ride which we liked but if you get seasick keep this in mind.

Loved every second of the trip. Lots of friendly chat from the guides and great diving locations. Beautiful reefs and amazing fish. Lucky to say I also got to swim with a turtle that came up from the reef for about 15 minutes! Big bucket list moment ticked off! Good, basic lunch, but that's all that's needed when swimming and traveling on a high speed boat!
