Kauai Scuba Diving Requirements

Scuba Diving Safety

Hawaii doesn’t have any specific laws or regulations with regards to diving that you need to know about if you’re diving with a tour operator. Though, vessel operators must use diver down flags when diving in Hawaii. As always, tour operators state that you must be in good physical condition and have some swimming ability. Children must be at least 10 years old to scuba dive with a tour operator.

With that said, it’s always highly recommended to have a dive buddy when you’re out scuba diving in the waters of Hawaii, as it is anywhere else. This is particularly the case if you’re out diving without a tour operator or guide. In this situation, it’s also good practice to make use of diver down flags.

With more than 30 dive sites around the coastline, Kauai is one of Hawaii’s most popular diving locations.

Whether you’re looking for comfortable and easy shore dives or to challenge yourself with drift dives accessible by boat, Kauai will not disappoint. More than 400 fish species have been spotted around the island, along with other marine life such as Dolphins, Monk Seals, and Humpback Whales.

Koloa Landing

Kauai Dive

Ideal for divers of all experience levels, the Koloa landing has a maximum dive depth of 15m and can be easily accessed from the shore. It’s located on the south coast of Kauai and has historical significance as the site of the first sugarcane plantation on the island.

The easy shore access makes this site well-suited for those taking diving certification courses.

And in case you’re visiting anytime between December and April, you might just catch sight of the occasional Humpback Whale.

Hanaka’ape Bay

Vibrant Coral

Hanaka’ape bay is an ecologically important dive site as it provides shelter to the humuhumunukunukuāpuaʻa, which is the state fish of Hawaii. Another name for this site is “Whalers’ Cove,” due to its historical importance as a trade port.

The site is a typical shore dive and is protected from wind, surf, and chop. Both entry and exit points are convenient and can be reached via an erstwhile boat ramp. Hanaka’ape Bay is an extremely colorful dive, with vibrant corals and a rich marine life consisting of Eels, Octopuses, and Crabs.

Sheraton Caverns

Cave Diving

The Sheraton caverns are made up of three lava tubes and located just off the coast of Poipu beach. When diving into these caverns, I suggest you bring along a flashlight and camera so that you can capture their underwater beauty.

This location has dive depths of 10m to 20m and is accessible via boat; this is due to the kick-out difficulty. It can be dived from the shore, but I don’t recommend it due to the possibility of exhaustion. Since the entry and exit of this dive site are difficult, it’s best for intermediate to advanced divers.
