Why dive Kauai?

The lush, green island of Kauai and the remote, pristine island of Niihau make an enchanting backdrop to our more than 30 dive sites teeming with life and adventure. The warm waters of Kauai and Niihau are blessed with rich marine life, sea mammals and unusual ledges, arches, pinnacles and caverns. Hawaii is a great place to observe fish with over 25% of the species being endemic — that is they occur nowhere else on the planet! A few of these endemic species, such as the Bandit Angelfish, occur more frequently on Kauai than the other main Hawaiian islands.

Why dive Fathom Five?

Fathom Five is located just minutes from the most spectacular South shore diving on Kauai. Ocean Quest Watersports operates just minutes from the North shore and our favorite Kauai SCUBA shore diving location, Tunnels Beach . Having these two locations allows us to dive virtually anywhere on Kauai. We pride ourselves on our PADI 5 Star rating and our excellent, experienced, & fun-loving staff who will do their utmost to make your dives with us the highlight of your vacation! We now feature full PADI eLearning courses which help you get to the fun of diving while learning at the pace you want! Read more on this website and don’t forget to Like Us On Facebook!

My 16 year old son had a great time diving with Jessie. He said everything was explained well, she was nice, and he got to see some sea turtles which he was quite excited about. Jessie even sent some underwater photos which was super awesome to have. Of all the activities he did on Kauai, diving with Fathom Five was his favorite!

We did the two tank introductory dive with Jermey and had a blast! He was very thorough at teaching us about the gear and proper scuba safety procedures. We saw all sorts of ocean life and he was very knowledgeable of every fish! We even saw 6 huge sea turtles at one time! This is totally worth your time and money!

This place is awesome, that is all that needs to be said. We asked to see turtles and Walla we seen turtles, within a couple feet! You should dive with Fathom Five! And I went all the way from Ohio!

Scuba Diving with Fathom was the best. Jessie made us feel incredibly well taken care of and safe. The water visibility was great and we saw a huge variety of species. We ended up doing two dives in one morning– couldn’t have asked for a better scuba experience.

These people are the best. The dive master leads the group and points out undersea life that you could never find on you own. Their rental gear is superb, the boat ride is short, and the crew makes sure that you have a great experience. They’re a 10.

Have dove with Fathom twice and had great experiences both times. We did the shore dive- which is great, and a nice option if you get seasick on boats. Saw some cool fish and turtles – but most importantly the instructors always made us feel safe and confident. Very professional. Would definitely use them again.
