Kauai Scuba Diving Tours
Kauai sits in the middle of some of the clearest water in Hawaii, and the dive scene here splits cleanly in two: shallow shore dives off the south side near Poipu and Koloa Landing, and boat charters that run farther along the coast. This page gathers 13 bookable scuba tours, from a first breath on a regulator to an eight-hour run out to Ni'ihau, the so-called Forbidden Island. You can compare them all by price, rating and length before committing.
Kauai Scuba Diving Tours Compared By Price And Rating
Kauai sits inside one of the most dive-friendly stretches of water in Hawaii, and the roster here reflects that: 13 scuba-diving tours covering everything from first-breaths-underwater intro dives to two-tank boat trips and a full-day expedition to Ni'ihau (see Things To Do). From-prices run from $137 to $655 per person. Ratings are strong across the board, with several tours holding a 5.0 from divers who have already booked.

Check availability →How To Choose Between Kauai Scuba Diving Tours
The first split to make is certified versus beginner. Several listings, including Dive Kauai's Ultimate Dive Boat Adventure and both South Shore 2-tank options, accept certified divers only, so check your card before you book. Never dived before? Kauai's Ultimate Discover Scuba Dive needs no certification, and Fathom Five Divers runs a one-tank discover dive at Koloa Landing pitched squarely at newcomers.
Time and budget narrow it further. Short shore-based dives around 2 to 3 hours start near $137, while half-day boat charters with two tanks sit closer to $285 or $370. At the top end, Explore Kauai Scuba's Ni'ihau trip costs from $655 and runs about 8 hours, a full-day commitment reserved for divers who want the island's most remote reefs. Every listing here carries free cancellation.
When To Book Kauai Scuba Diving Tours
Book ahead rather than on arrival. Small-dive groups fill fast, especially the semi-private and exclusive charters, and the Ni'ihau expedition runs limited departures by nature of its length. Morning slots tend to go first, and calm South Shore conditions near Poipu make the earlier start worthwhile. Lock in your date early, then confirm gear sizes and meeting details through the live booking page.
