In this post, I break down the best Hawaii scuba diving experiences, coolest Hawaii scuba tours, and where you’ll find the best diving in Hawaii.
And at the end, I’ll give you a handy Hawaii scuba diving safety checklist to make sure you have the best Hawaiian adventure!
Before we get too far, let’s answer a few of your top Hawaii scuba diving questions:

Top Questions about Hawaii Scuba Diving
Is Hawaii good for scuba diving?
Absolutely!
Hawaii actually an archipelago in the Pacific Ocean that’s made up of 8 islands. In addition, there are islets and atolls. That’s a lot of opportunity for some fascinating underwater adventures!
Both advanced and beginner divers flock to Hawaii to check out Hawaiian sea life (like the famous Hawaiian Green Sea Turtles), explore old shipwrecks, swim with Manta Rays, and even see sharks!
Hawaii offers some incredible, once-in-a-lifetime diving experiences!
Is scuba diving in Hawaii dangerous?
There is always some risk when it comes to scuba diving in open water. But, the best rule of thumb when diving in Hawaii is DON’T BOTHER THE SEA LIFE and they won’t bother you!
Yes, you might encounter Sharks in Hawaii (like the Whitetip Reef Shark or Tiger Sharks.) But, sharks usually only attack if they are provoked, or if they think you are food.
However, you’ll want to steer clear of Sea Urchins in Hawaii. They have long spines that can pierce through a wet suit.
Eels are another Hawaii sea creature you’ll want to give a wide berth to. They have razor-like teeth and if they bite you, you might get muscle damage.
And don’t bother the Sting Rays. Like their name suggests, they might sting you if you get too close or touch them.

Which Hawaiian island is best for scuba diving?
This one is a tough call.
If you are planning a trip to Hawaii where scuba diving is your main priority, I’d definitely plan on going to Lanai. It’s known for its crystal clear water and they have awesome cavern diving. You will be in awe.
Maui also has some cool scuba diving experiences. Molokini Crater is just off the coast of Maui and is a great spot to see Hawaiian Green Sea Turtles, Eagle Rays, and tropical fish.
Plus, it’s really close to Lanai (if you want to do a day trip there to go diving.)
One of the most popular places to scuba dive in Hawaii is Kona on the Big Island. They have some spectacular reef, cool underwater lava formations, and the famous Manta Ray Night Dive.
Oahu has a lot of Hawaii scuba tours that are perfect for beginners. Plus, there are some great opportunities to see shipwrecks.
There are lots of cool diving spots on Kauai. And there are even some where you won’t need a boat!
Molokai is another good option and makes a great stop if you plan on island hopping in Hawaii. You have a good chance of seeing Hammerhead Sharks and Hawaiian Monk Seals.

Where can I get a Hawaii scuba certification?
If you’re thinking about getting your scuba diving certification, Hawaii is a fun place to do it! Plus, they offer several different courses, including deep diver and wreck diver courses.
For scuba certification on Oahu, there are a ton of options. A few include Kamaaina Divers, Oahu Diving, Living Ocean Scuba, Dive Oahu, or Island Divers Hawaii.
For scuba certification on Maui, head to Maui Diving, Banyan Tree Divers Maui, Scuba Mike, Prodiver Maui, or Maui Dreams Dive Co .
For scuba certification on Kauai, head to Bubbles Below Kauai, Kauai Down Under Scuba, Seasport Divers, Garden Isle Divers, or Explore Kauai Scuba.
For scuba certification on the Big Island, head to Big Island Divers, Kona Diving Company, Jack’s Diving Locker, Kona Honu Divers, or Kohala Divers ltd.
Can you scuba dive in Hawaii without certification?
Absolutely. Although the safest way to do that is with a guided scuba dive tour in Hawaii.
Like we mentioned earlier, there are lots of dangerous things in the ocean and it’s always safest to have an experienced scuba diving tour guide help you.
Plus, it’s the easiest way to get to cool Hawaii dive sites!

What’s the cost of scuba diving in Hawaii?
It really varies. There are a few different things that can change the cost of scuba diving in Hawaii:
Boat Diving will either require you to charter a boat or join a guided scuba diving tour.
Shore Diving is a cheaper way to go scuba diving in Hawaii, but it’s really only an option for experienced divers.
How old do you have to be to go scuba diving in Hawaii?
For families that just want to let their kids get a feel for scuba diving, you can sign up kids as young as 5 years old for non-certification scuba classes.
If you want to get a scuba certification with kids in Hawaii, they need to be at least 10 years old for most courses. There are a few that accept kids as young as 8 years old. You can sign up and do classes as a family.

Safe Scuba Diving in Hawaii Checklist
Scuba diving is an exhilarating sport and a window into a new world. Make sure you dive problem-free by preparing carefully and knowing your limits.
Problems in scuba diving can escalate quickly. One small issue can turn into a couple of slightly bigger issues, and those can turn into a disaster.
Learn to pay attention to the small things ahead of time so you can deal with them and minimize the chance of a major problem.
One day, when you have hundreds of safe and wonderful dives in your logbook, you’ll be glad you did.
Here are 5 things to consider before any Hawaii scuba dive:

1. How Do You Feel?
A day of diving can easily be ruined by illness. It only takes a little congestion to prevent equalization, causing the most common diving injury, ear barotrauma.
If you are tired, hung-over, or dehydrated, you’re more susceptible to decompression sickness and less ready to deal with unexpected situations underwater.
Even if you’re on vacation and you’ve been looking forward to the trip, give yourself a break and wait for the next day.
As great as Hawaii diving can be, it’s not worth health complications that are easily prevented.
2. Do You Have All Your Equipment and is it Working Correctly?
Whether you’re leaving your house or a hotel room, take a few minutes to check your dive bag before you leave.
Verify that you have all the things you need for your dive. It’s easy to walk out the door without something small but essential, like your dive watch or dive computer.
Once you arrive at your dive site or you’re on the boat set up, check the function of your equipment as you put it together.
Don’t ignore potential problems.
It’s a good idea to carry a small kit with spare parts and basic tools so you can make simple repairs on the spot. If you’re diving with a commercial operator, they probably have parts and tools with them also.
If you have an equipment issue and you can’t fix it or rent or borrow a replacement, know when to cancel the dive.
Diver training organizations teach buddy checks.
Once you’re ready to go in the water, take a couple of minutes to go over the equipment with your buddy. Each one makes sure the other has all the necessary gear in working order before the dive begins.
3. How Will You Communicate and Where are You Going?
If you’re diving in Hawaii with a buddy only, agree on hand signals and a dive plan before you hit the water.
If you’re diving with a dive guide, listen to the briefing before the dive.
It’s inevitable that the person who is not paying attention during the briefing is the one who jumps in the water and swims in the wrong direction.
A professional divemaster or instructor leading a group will review hand signals and dive procedures before every dive.
4. Does Someone Know Where You Are?
If you are diving in Hawaii on your own with friends, have you told someone where you are and when you’ll be back?
If you’re diving with a commercial operator, do they have a method for accounting for all the divers in the group?
Were you asked to take a tag with you and return it when you return to the boat?
Did they do a roll call before the boat left the dock?
The movie Open Water was an exaggerated Hollywood story, but it’s up to you to be comfortable that the dive operation knows where you are, so nothing like that ever happens.
Once you’re in the water, do you have a way of signaling someone if you have a problem? Are you carrying a whistle, mirror, or safety tube so you can get someone’s attention?
5. Does Your Dive Match Your Training and Experience?
Be smart. Don’t try a dive that’s way beyond your level. Gradually increase your skill level.
Try a dive with a more experienced diver that’s slightly more advanced than what you’re used to.
Sign up for a class to experience new types of dives.
If it’s been a while since your last dive, take a refresher class or dive with a guide the first dive or two.
And if something unexpected happens, remember to stop, breathe, think, and then act. This is important because if you are still breathing, you have time to handle the situation.
All the preparation you’ve gone through makes it less likely there will be a problem.
This may seem like a long list, but once you make it a part of every dive, it will become routine. Committing to careful preparation results in safe and fun scuba diving.
And isn’t fun what diving is supposed to be all about?
