Starting Out at Kawaihae Harbor
Your journey begins early, with a meeting at Kawaihae Harbor at 9:00 am. This harbor offers a calm, accessible launch point for the tour, and it’s small enough that the check-in process feels personal rather than crowded.

Once underway, the boat’s design ensures a smooth ride, allowing everyone to relax and take in the scenery. This is an aspect many reviewers highlight—how the boat’s stability and speed make the trip enjoyable even if you tend to get seasick or prefer a less jarring ride.

Snorkeling Spots: The Ocean’s Hidden Treasures
The crew’s decision on where to snorkel is based entirely on safe conditions and marine activity. This flexibility is a real advantage, as it means you’re more likely to see vibrant coral gardens, tropical fish, and sea turtles.
One reviewer raved, “Absolutely a fabulous experience. I saw two sea turtles and so many beautiful fish. The cocktails flowed after we finished.” That last part—yes, post-snorkel cocktails—adds a relaxed, fun vibe to the experience. It’s clear that the crew aims to make your time both exciting and comfortable.
