What Makes This Tour Unique?
This tour isn’t your typical beginner-friendly snorkel or casual dive. It’s tailored specifically for experienced divers who want to explore Kauai’s underwater geology and wildlife in a meaningful way. With over 37 years of local expertise, Seasport Divers knows exactly where to go to give you a memorable, visually stunning experience.
The highlight is definitely the Sheraton Caverns, a location famed for its lava tube formations. These geological features, carved by fire and water over countless centuries, create sprawling tunnels and grand archways that are a thrill to navigate. It’s the kind of dive that makes you feel like you’re exploring an underwater cathedral—only with the added bonus of spotting sea turtles and other species that call these caves home.
Beyond the lava tubes, there are other popular sites like Brennecke’s Ledge, Fish Bowl, and Ice Box. These spots are known for larger species, including sharks, manta rays, and even dolphins when in season. The chance to see humpback whales adds to the excitement if you’re lucky and visiting at the right time.
What’s Included and How Does it Add Value?
For $259.11 per person, you’re getting more than just a boat ride. The package includes all fees and taxes, which simplifies the booking process. You also get coffee, tea, snacks, and bottled water—important touches that keep you comfortable during the roughly four-and-a-half-hour excursion.
The onboard warm showers are a thoughtful feature, especially after a chilly dive. Plus, the availability of rental gear makes it accessible for divers who may not have their own equipment or want to travel light.
The Itinerary: What to Expect
The tour starts at 2827 Poipu Rd in Koloa, where you’ll meet your crew from Seasport Divers. Expect a small group setting (up to 14 travelers), which means more personalized attention. After a safety briefing and gear check, you’ll head out to the dive sites.
The first stop is often Sheraton Caverns, where the lava tubes await. This site is a favorite, not only for its geological marvels but also for encountering sea turtles, as one reviewer noted, “Tons of sea turtles!” The experience of swimming through lava arches and tunnels is truly special, and seasoned divers love the opportunity to explore these features in a controlled, guided setting.
Other sites like Brennecke’s Ledge and Ice Box are selected based on conditions, but they offer opportunities to spot larger marine species. Due to the depth of roughly 100 feet, these dives are suited for those comfortable at depth, and the experience level is considered moderate to high.
