A memorable afternoon on the water awaits you with the Afternoon Sail & Snorkel to the Captain Cook Monument on Hawaii’s Big Island. For about three hours, you’ll cruise the Kona coast aboard a sleek trimaran, heading to one of Hawaii’s most celebrated snorkeling spots—Kealakekua Bay. At $136.19 per person, it’s a well-priced way to enjoy marine life, scenic views, and a touch of Hawaiian culture. The tour departs from Keauhou Bay at 2:00 pm, making it a perfect late-afternoon escape from the more crowded beaches.
Two things we particularly like about this experience are the personalized vibe—with only around 17 guests on most trips—and the chance to see spinner dolphins, which frequently swim close to the boat. The crew’s attentiveness and knowledge, combined with the colorful coral reef and friendly atmosphere, elevate this tour beyond just another snorkel trip. A potential consideration is the 3-hour duration, which might feel short for some, especially if you’re eager to spend more time in the water or exploring.
This tour suits travelers who love marine wildlife, appreciate beautiful scenery, or are looking for a relaxing, well-organized adventure that offers genuine Hawaii charm. Families, first-time snorkelers, or those wanting a more intimate, crowd-controlled experience will find it particularly appealing.

Setting Sail from Keauhou Bay
The adventure begins at Keauhou Bay, a calm and scenic launch point with easy parking and access. As you board the trimaran, you’ll notice the vessel’s sleek, stable design—perfect for a smooth ride along the coast. Most trips host about 17 guests, though the maximum is 44, which keeps the environment intimate without feeling crowded.

Most of the trip involves relaxing on the deck, soaking in the ocean breeze, and watching waves roll by. The crew’s casual professionalism makes it clear they want everyone to feel comfortable—whether you’re an experienced sailor or a first-timer. You might find yourself chatting about Hawaii’s volcanic history, spotting distant whales, or simply marveling at the seabirds overhead.
Snorkeling at Kealakekua Bay
Once you arrive at the Marine Preserve, your guides will help you gear up, providing masks, fins, snorkels, and flotation noodles.

The monument, built where the famous explorer was killed, is set against the backdrop of the bay’s volcanic cliffs. It’s a peaceful spot for underwater exploration, with the added thrill of possibly seeing spinner dolphins swimming nearby—something many reviews rave about.
Guests often comment on how close the dolphins come to the boat, sometimes swimming underneath or around the vessel. “Dolphins swam close to the boat,” one reviewer shared, adding that it was “wild to see the baby whale breach,” a rare but memorable moment.
