Kauai, known for its dramatic cliffs, lush rainforests, and vibrant coral reefs, hides some of the Pacific’s most spectacular dive sites just offshore. This trip goes beyond the usual spots and opens the door to adventures at Amber’s Arches, Kipu Kai, and the challenging Mana Crack. Each dive site brings a unique flavor: Amber’s Arches boasts stunning coral formations resembling natural gateways, Kipu Kai offers pristine water and diverse marine life, while Mana Crack challenges divers with deep fissures and thrilling drift dives.
The Anuhea, a 32-foot power catamaran, provides a stable and comfortable platform, perfect for navigating Kauai’s coastal waters with ease. With a maximum of six participants, divers receive attentive briefings and tailored support throughout the day. Nitrox mixes are available for those qualified, extending bottom time and enhancing safety on deep dives.
What makes this trip stand apart is its blend of rare dive sites coupled with a small-group dynamic, allowing plenty of time to savor the marine environment without the rush or crowds typical of larger charters. From spotting reef sharks and colorful reef fish to the occasional Hawaiian green sea turtle, encounters with marine life are a highlight.

Participants are advised to bring reef-safe sunscreen, towels, and swimwear, while gratuities for the crew are not included. Prior certification is mandatory, reflecting the trip’s focus on experienced divers ready for moderate to challenging underwater terrain.
