Kealakekua Bay Afternoon Snorkel: Family Fun on the Kona Coast
Imagine gliding through crystal-clear waters, surrounded by colorful fish and coral, with a chance to spot dolphins, turtles, or even whales in winter—all in a relaxed 3.5-hour trip. This snorkeling cruise departs from Keauhou Bay and takes you along the scenic Kona coast before reaching the famous Kealakekua Bay Marine Preserve, home to the Captain Cook Monument. The tour costs around $144 per person, making it a moderate investment for such a rich experience filled with marine life, fun water slides, and comfortable amenities.
What we love most about this trip is the combination of a scenic coastal cruise with exceptional snorkeling and the lively onboard atmosphere. The crew’s friendliness and knowledge shine through, creating a welcoming environment for beginners and seasoned snorkelers alike. Plus, the 15-foot water slide and diving platform offer fun for all ages, turning the trip into a true family adventure.
One possible consideration is that this tour doesn’t include hotel pickup, so you’ll need to plan your transportation to the meeting point in Kailua-Kona. Also, it’s a popular choice, so booking at least 26 days in advance is advisable if you want a spot.
This trip is best suited for families, first-time snorkelers, and anyone wanting a well-rounded, enjoyable afternoon with good marine viewing, comfortable equipment, and a lively crew.

A Deep Dive into the Experience

Starting Point and Departure
The tour begins at 78-7130 Kaleiopapa Street in Kailua-Kona. It’s a straightforward meeting spot, and the boat departs at 1:30 pm, making it a perfect mid-afternoon activity. We appreciate the clarity in start times, as it allows for a relaxed day and avoids the early morning rush. The boat is large, comfortable, and designed to accommodate up to 100 travelers, which means it’s lively but not overcrowded—a common concern on popular tours.
Scenic Coastline and Dolphin Watching
As we motor along the coastline, the crew keeps watch for spinner dolphins, often seen splashing near the shore. Several reviews highlight the excitement of seeing dolphins swim alongside the boat or even jumping near the bow. One guest shared, “On the way back, we saw dolphins swimming along side the boat,” adding a magical touch to the journey. The crew’s knowledge about marine life and the environment is evident—they’re happy to point out wildlife and share insights, making the voyage more engaging.
Kealakekua Bay and the Captain Cook Monument
Arriving at Kealakekua Bay, the highlight is the 1.5 hours of snorkeling in some of Hawaii’s clearest waters. The bay is renowned for its vibrant reef and abundant marine life. Guides assist with snorkel gear—offering different options for varying ability levels—and provide safety instructions, especially for novices. Many reviews mention how “equipment was clean and comfortable” and how helpful the staff was in helping those new to snorkeling.
The Captain Cook Monument adds a historical layer—the bay is named after the British explorer who was famously killed here. While most don’t have time to explore the land, the view from the boat and the underwater scenery make this stop special.
Snorkeling and Water Fun
Once in the water, you’ll find yourself swimming among schools of colorful fish and corals. The reef is lively, and many say it’s comparable to “swimming in an aquarium,” as one reviewer noted. Flotation devices, such as inner tubes and boogie boards, help non-swimmers or those who prefer to float rather than swim.
After snorkeling, the fun continues with a 15-foot water slide off the boat’s deck and the dive platform. Climbing to the top and zooming down into the water is a highlight for kids and adults alike—adding a playful element to the trip. Several guests mention how “the slides and jumping platform were a great time,” reinforcing how this tour combines adventure with relaxation.
Snacks and Refreshments
Back on board, you’re treated to fresh tropical fruit and island-made sweet potato chips, which are appreciated after the exertion in the water. Beverages are available for purchase on the return trip, rounding out the experience. The crew’s eco-conscious approach—using reef-safe sunscreen and reusable cups—resonates well with environmentally-minded travelers.
