Fathom Five Divers

Say aloha to Kauai's underwater world with Fathom Five Divers, the Garden Island's longest-running dive shop. Based in Old Koloa Town on the south shore — five minutes from Poipu Beach and Kukuiula Harbor — the center has been guiding divers for over 43 years, earning a PADI 5-Star Instructor Development Center rating and a spot as Best Dive Shop for Beginners in the Ultimate Kauai Guidebook.

Small Groups, Big Dives

Every custom-built boat is capped at just 6 divers, and all 20+ south shore dive sites sit within 15 minutes of the harbor, making a two-tank trip a comfortable half-day out. With 30+ sites island-wide — plus a second location near Tunnels Beach on the north shore — you'll meet sea turtles, dolphins, and rare endemic fish, with three-tank Niihau charters to Lehua Rock running May through September.

PADI courses run from Discover Scuba Diving through Open Water, Advanced, Adventure Dive specialties, and Enriched Air/Nitrox, with full eLearning available. Perfect for beginners and anyone craving that unhurried island pace.
