Diving with sharks is the type of activity that you do once in a lifetime. Your friends simply won’t believe it and your mother will call you crazy. However, here on Oahu, it is one of the most popular activities for tourists to experience swimming with sharks up on the North Shore. In this guide, I will share with you all of the best places to go shark diving without a cage on Oahu (and with a cage) and what each different tour operator has to offer compared to the others.
Will you swim with sharks on Oahu WITH or WITHOUT a cage?

SHARK DIVING ON OAHU WITH OR WITHOUT A CAGE?
There are two main types of Oahu shark diving tours for you to choose from. Despite what you might be thinking, both are pretty safe. I’ve done both multiple times.
WITH A CAGE: The first option is to be inside a cage as the sharks swim around you.
WITHOUT A CAGE: The second option is to be cageless and snorkel above the sharks and free-diving down to be amongst the sharks.

I personally enjoyed both experiences and found the shark encounter with the cage to be more interactive as the sharks were closer and more inquisitive. However, the cageless shark encounter on Oahu was much more peaceful as the sharks circled below. I would recommend both and many visitors to Oahu who love sharks will actually do both tours aswell.
Below, I will detail the different tours available and why you might choose one Oahu shark diving experience over the other.
NORTH SHORE SHARK ADVENTURES: CAGE DIVING EXPERIENCE
The North Shore Shark Adventures company is one of the biggest on the island and they have an impeccable record and high professionalism. This tour takes you out from the harbor at the North Shore for an incredible shark cave diving experience on Oahu.
This tour by North Shore Shark Adventure is by far the most affordable on the island and the only tour under $100 per person. The tour runs for two hours and the experienced crew will lead you through the following itinerary.
- Head off from the North Shore boat harbor to the shark-viewing spot.
- Along the way, it’s likely to spot dolphins, turtles and whales depending on the season.
- Listen to the briefing about how to behave in the cage and a short overview of shark behavior.
- Enter into the shark cage with your snorkel on and enjoy an observing the sharks.
The cage is half in the water and half out so you can always raise your head above water. You never need to swim and simply hold onto the cage while breathing through your snorkel. It’s not difficult at all and very easy even if you aren’t a good swimmer. With unbelievable water clarity, you will be able to see Sandbar, Galapagos, and maybe even Hammerhead Sharks.



ONE OCEAN SHARK DIVING – WITHOUT A CAGE
Swimming with sharks is one of the most unique activities to do on Oahu. Imagine being in the water, snorkeling, and free-diving with a ‘shiver’ of sharks circling below. This may sound extreme but it’s what this Oahu shark dive experience is all about with the team from One Ocean Diving.
This is no average shark diving tour. One Ocean Diving is all about shark conservation and helping visitors understand sharks and what we can do to protect them. That’s why you’ll find a marine biologist (or two) on board.
It may sound a bit dangerous but it is very controlled and they have a perfect safety record. With your snorkel gear on, you will hold onto a line and watch the sharks circling below. You will have the opportunity to free-dive down towards the shark with the supervision and guidance of your expert instructor. The free-diving part is optional.
Swimming with sharks on Oahu is one of the most awesome experiences you can have on the island and I highly recommend it!


NOTE: Those two tours above are definitely my top-rated tours for shark diving on Oahu and I’ve personally experienced both of them multiple times! However, there are a few other tours that are highly recommended for swimming with sharks on Oahu and I’ll share those with you below.
OAHU PELAGIC SHARK DIVING with ISLAND VIEW HAWAII
Operating out of Haleiwa on the North Shore, Island View Hawaii is another company running shark diving tours ‘without’ a cage. Island View Hawaii teaches visitors how to communicate with sharks in order to coexist peacefully together in the ocean.
This 2-hour tour runs out of the North Shore boat harbor before ferrying you out to the 250ft deep shark diving zone. An experienced instructor will guide you as you hold onto a rope. You can expect to swim with sharks but also keep an eye out for dolphins, whales, turtles, and other marine life on this incredible pelagic dive.

HAWAII SHARK ENCOUNTERS
The final tour I will recommend in this blog post is with Hawaii Shark Encounters for their Oahu Shark Cage-Diving experience.
This 2-hour experience up on the North Shore is an adrenaline-filled activity where the experienced team takes you out from the harbor to their permanent cage site. Here, with depths of more than 200ft, you will be submerged into the cage with snorkel gear on.
Don’t be afraid, but sharks will be circling the cage right around you in a once-in-a-lifetime experience. You might not expect me to say this but it is actually quite a peaceful experience rather than a scary activity. You can get some seriously cool photos and videos from inside the cage with the sharks coming right up close to investigate.


IS SHARK DIVING SAFE ON OAHU?
Shark diving on Oahu and in general is a relatively safe experience. The sharks you are likely to encounter in Hawaii and specifically on these tours are Sandbar Sharks and Galapagos Sharks, which are less aggressive. While it is possible to see Hammerhead Sharks and even a rare sighting of a Great White Shark, it is uncommon.
One Ocean and North Shore Shark adventures have a perfect safety record and despite what you see in the movies, sharks are relatively peaceful and just going about their business in the ocean. They aren’t naturally aggressive towards humans and that’s why the guides are important to monitor the behavior of the sharks and the tourists to make sure both sides are calm and staying that way.

Have you got travel Insurance?

- Don’t wait for an accident to happen… get insured! My travel insurance is SafetyWing which offers low-cost travel & medical insurance. That’s me in the photo below with three teeth knocked out after a motorbike crash in Bali
- I’ve made several successful claims with SafetyWing and find their customer service very quick and helpful.
- SafetyWing’s Essential plan covers travel and medical emergencies with options for adventure sports and electronics theft. Their Complete plan offers comprehensive health coverage with routine healthcare, mental health support, and maternity.
WHAT SPECIES MIGHT YOU SEE WHILE DIVING WITH SHARKS ON OAHU?
- Sandbar Shark: This is the most commonly sighted shark year-round and is quite peaceful. Don’t be surprised to see thirty or more of these sharks circling below.
- Galapagos Shark: It is relateivley common to come across a Galapgos Shark while diving with sharks on Oahu.
- Hammerhead Shark: This species is a little less common but not something unusual to Oahu
- Great White Shark: Each year there are Great White Shark sightings in Hawaiian waters, which are most likely to occur in the winter months.
- Whale Shark: Oahu doesn’t see many whale sharks but sightings do happen. It’s much more likely to spot a whale shark on other Hawaiian Islands such as Niihau, Lanai and the Molokini Islet.

GEAR YOU NEED FOR SWIMMING WITH SHARKS ON OAHU
Your tour operator will provide you with a mask, snorkel, and fins and may even be able to provide you with a wetsuit. Most snorkelers will just wear boardshorts, bikinis, or bathers as you will only be in the water for 20-30 minutes whether in the cage or out of the cage. They will also provide you with a towel for after you get out of the water.
Just wear your flip-flops and bathers and don’t forget to bring reef-safe sunscreen.

SHARK MYTHOLOGY IN HAWAII
Shark or “Mano” in Hawaiian, is still central to the culture of the native Hawaiians and is featured in many legends. Hawaiians today still revere the shark and honor them as ancestral familial Gods of long ago. They are one of many central figures in Hawaiian mythology and are featured in countless legends throughout the Pacific. The shark God Kamohoali`i guided his sister Fire Goddess Pele on her journey as she escaped a feud with her sister which resulted in the creation of the Hawaiian Islands. This tour takes you on a journey to see one of the many forms of sharks, the descendants of Hawaiian folklore, and witness their agility and gracefulness as they glide by just inches away from you. All this and a breathtaking view of Oahu’s North Shore are part of the Hawaii shark tour.

HOW TO GET TO THE NORTH SHORE BOAT HARBOR
No matter which tour you choose, they will both begin from the North Shore boat harbor. There is usually enough parking there but I wouldn’t leave any valuables in the car. The check-in station is at the harbor and they will load you up into the boat. To get to the harbor on the Haleiwa Harbor it takes about an hour depending on traffic. Make sure you give yourself some breathing room because if there is a jam or an accident it could increase your transit time by thirty minutes or more. I’ve included a map below with a pin location of the Haleiwa Harbor.
What are my favorite pieces of gear for the beach?
There are three pieces of gear that I simply never forget when I go on a beach adventure. These are three items that I using right now and this list gets updated every year! Here are my beach essentials.
- Quick-Dry Towel: A quick-dry towel is a must for travelers. It hardly takes up any room and dries in seconds.
- Osprey Ultralight Dry Sack: The beach can be a great place to ruin your precious gear so having this ultralight dry sack for cameras, phones and valuables mean you have a safe place to store everything.
- GoPro Hero 12: The best and easiest way to capture your underwater and snorkeling adventures.
THE FOUR MOST POPULAR OAHU TOURS
- Doors-Off Oahu Helicopter Flight Tour: My number one recommendation is to do a heli-flight (doors off) and be blown away when you see Oahu from the air.
- North Shore Shark Cage Tour: The biggest adrenaline rush you can have in Hawaii is beneath the surface with sharks!
- Eco-Friendly Dolphin and Snorkel Tour: One of the best experiences I had on Oahu was swimming with the beautiful spinner dolphins on this exact tour.
- Turtle Canyon Snorkel Cruise by Catamaran: The number 1 MOST POPULAR snorkel tour on Oahu. GUARANTEED Turtles!
WHERE TO STAY ON OAHU
- Hilton Hawaiian Village Beach Resort (Overall Favorite): In the heart of Waikiki, this high-end resort is right on the beach with a private lagoon.
- Sheraton Waikiki (Luxury): A luxury resort with the most amazing infinity pool on the island, which overlooks the beach.
- Ewa Hotel Waikiki: (Value): Ewa Hotel is just one block back from the beach and is just over $150 USD.
- Waikiki Beachside Hostel (Budget Choice): A budget alternative, which is still in an amazing location.
- Disney Aulani Resort (Family Choice): This is a resort your kids will never forget. It honestly feels like you are living in a theme park.
