Kauai is a snorkeler’s paradise. The island’s clear waters, vibrant reefs, and abundant marine life make it a top destination for underwater exploration. What sets Kauai apart is its dramatic coastline—steep cliffs, hidden sea caves, waterfalls tumbling into the sea—and its variety of tours that cater to different preferences. We’re especially fond of the Nā Pali Coast Zodiac Raft Expedition for its wild, adrenaline-fueled approach that gets you up close to some of the most inaccessible nooks of this rugged coast.
If you prefer a more laid-back experience, the Napali Coast Boat Tour and Snorkeling offers leisurely sightseeing with plenty of marine life encounters. And for those craving an intimate adventure, the Ultimate Na Pali Coast Zodiac Boat Snorkeling and Sea Cave Tour combines small-group exclusivity with access to caves and secluded spots that big boats can’t reach.
