South Shore Boat Diving

Kauai Down Under operates a 25 ft. ZODIAC RIB (Rigid hull Inflatable Boat) called the “Hokupa’a”.  Our ZODIAC is a US Coast Guard approved vessel for sixteen passengers that takes visitors to areas of marine interest along Kauai’s southern coast. When you’re diving with us we generally have 6 divers or less to ensure everyone has a unique and memorable experience. Kauai Down Under is the only company on Kauai that incorporates a zodiac adventure while you dive in the gentler waters off of Kauai’s south shore.
Encounter occasional dolphins an abundance of exotic Hawaiian reef fish and beautiful coral formations.  Let’s not forget, one of the most exciting creatures we will encounter is the Honu; i.e. the Hawaiian green sea turtle. There is so much to see on these southern coasts in terms of pristine reefs and off-shore caverns that diving in these areas becomes a true pleasure. The fish in these areas are plentiful, the reefs are gorgeous and the weather is almost always sunny and beautiful. Our Captain and crew look forward to sharing their passion and knowledge of marine life and island history with you.

South Shore Kauai Scuba Diving

The most popular south shore dive site is called Koloa Landing. This is a shore dive located in very protected Hanaka’ape Bay, which is sheltered from surf, wind, and chop. The entry and exit point is a convenient former boat ramp which we use to access the reef. There is very little surface swim involved, as the dive site begins just steps off the ramp. We set up all of your equipment close to the water in a comfortable setting complete with carpet, chairs, and an ice chest full of refreshments and snacks. Koloa Landing is known as a colorful dive, full of vibrant stony corals as well as a huge abundance of marine life. The large horseshoe-shaped bay allows us to dive in two distinct areas, perfect for a two tank excursion. The maximum depth here is approximately 50 feet with an average bottom time of 45 minutes, depending upon air consumption. Our dive times are 8:00 am, 1:00 pm or dusk. Mornings are typically calm on the south shore of Kauai with trade winds picking up in the early afternoon, so our morning dives are amazing.

Coralfish - Kauai Scuba DivingThe animals we encounter at Koloa Landing on a regular basis are: Hawaiian Green Sea Turtles, up to seven species of moray eels (including the rare dragon eel), leaf and devil scorpionfish, octopus, hermit crabs, a variety of invertebrates (cone snails, auger snails, helmet snails, shrimp, sea stars, urchins), and hundreds of tropical fish! We also have a pair of Hawaiian scarlet cleaner shrimp who will hop right into your mouth if you let them to clean your teeth! This is their job for the fish living on the reef! On rare occasion, we are lucky enough to encounter frog fish, dolphin, spotted eagle rays and even the elusive Reef or Galapagos shark. During the months of December through April, we are also fortunate to hear the sound of Humpback whales singing during our dives here.

North Shore Kauai Scuba Diving


The most popular north shore dive site is called Tunnels Reef. This reef is located approximately 15 minutes past Hanalei on a beautiful white sand beach with stunning Bali Hai views. We set up all of your equipment close to the water in a comfortable shaded setting. Chilled refreshments and light snacks are provided. Tunnels Reef is a wall dive which is located just steps from the waters’ edge. The reef itself is an ancient lava flow full of cracks, crevices, and large caverns which spiral through the reef. We have both an inner and an outer reef, which makes Tunnels Reef perfect for a two tank experience. This site is known for having some of the best topography on the entire island. As divers, we can venture through the lava formations that are full of sunlight and have crystal clear visibility (only certified divers can go through overhead environments). This site is famous for its’ topography as well as for the chance to see larger pelagic animals. The maximum depth here is 55 feet with an average bottom time of 45 minutes, depending upon air consumption. The dive time at Tunnels Reef is 8:00 am. We do not conduct afternoon dives at Tunnels Reef because it gets very windy and the visibility dramatically decreases.

Tunnels - Dive KauaiThe animals that we encounter at Tunnels Reef on a regular basis are: large Hawaiian Green Sea Turtles, White Tip Reef Sharks, Spotted Eagle Rays, schooling Barracuda, and a variety of Silver Jacks. We also see Spiny Lobsters as well as different Nudibranchs inside of the caverns. There is not much coral at this site as the main attraction is the lava tubes and tunnels that make up the formation of the reef itself.

We dive at Tunnels Reef Monday through Friday during the calm summer months, generally from May through September, conditions permitting. There is no diving allowed weekends or holidays at Tunnels Reef due to local regulations.
