The Experience Overview

What makes this tour stand out is its promise of a “ride of a lifetime” beneath the Hawaiian waves aboard a submarine once featured in National Geographic. That’s a big claim, but many guests find it lives up to expectations. The Atlantis submarine is known for its stability and comfort, with a clear view from inside that feels like floating in a fishbowl. The entire journey takes around 1.5 hours, with roughly 45 minutes spent underwater exploring the ocean floor and marine life.

Starting at the King Kamehameha Kona Beach Hotel, the check-in process is straightforward.

Once aboard, you’ll board via a special ladder—an experience in itself—and settle into your seat for the descent.

What You Will See

Once submerged, you’ll descend more than 100 feet, providing a fish-eye view of the underwater world. The tour explores a 25-acre area filled with vibrant coral, a variety of fish, and notable shipwrecks, adding an element of mystery and history. Reviewers consistently mention their awe at seeing marine creatures and colorful reefs that are normally hidden from view.
