Shark Cage Diving in South Africa: My Experience Swimming With Great White Sharks (a Practical Story)

Shark cage diving in South Africa sounds cool and easy. It’s not—I tried it myself. You wake up early, get thrown around on a boat, freeze in the water while still being nauseous, and hold your breath hoping a shark swims by. Here’s what I thought of the experience and what to expect if you go yourself.

My assistant was kind of surprised when she found out I wanted her to organize my vacation along the coast of South Africa. What perhaps surprised her the most though was the shark cage diving I wanted to include.

 I’m not going to lie; it was a shark cage diving experience that I won’t ever forget—but not just for the reasons I expected. What did I expect and how did it turn out in reality? Grab some popcorn and sit back while I tell you how it went. Or just skip ahead and join a shark cage diving tour yourself if you’re feeling brave.

Shark cage diving in South Africa: quick facts before you go

• Starts early: pickup is often around 4–5 am 
• Total time: about 6–10 hours (including driving + boat time) 
• Location: usually Gansbaai (about 2–3 hours from Cape Town) 
• Water temperature: around 10–15 °C (cold, even with a wetsuit) 
• Time in the cage: each person gets a few short turns in the cage, not one long dive
• No scuba diving: you hold your breath and dip under when sharks come 
• Seasickness is common: rough water is normal, everyone on my boat was nauseous 
• Shark sightings aren’t guaranteed, but chances are high 
• Price: roughly ZAR 2,500–4,000 (130–220 USD) depending on the operator 
• Is shark cage diving worth it? Yes, but it’s uncomfortable, pretty short for the price, and the boat trip can be rough.

My expectations: Just a quick cool selfie with the great white sharks and back out to the deck?

First of all, shark cage diving was all my idea. Despite my knowledge about the white shark, with a length of up to six meters (20 feet) and weight of about three tons. This monster can live up to more than 70 years and it belongs among the fastest shark species.

The great white shark is also a synonym for man-eating, as it holds the record for attacking humankind among all the shark species. 

Their reputation as aggressive predators is part of what makes this experience so thrilling. While great whites dominate this area, species like tiger sharks are found in other parts of the world and offer a very different kind of encounter.

Regardless of what I just told you, my idea of this activity was quite simple. Hereby I attach a rough illustration of what I thought it would look like:

To put it simply, as soon as I was reading the travel itinerary, I pictured myself bragging to all of my friends and showing off my ability to handle a close encounter with a great white shark. Imagine my glorious self with pumped up muscles and a tamed white shark in the background.

If your instincts are telling you this was nowhere near reality, you’re right.

What shark cage diving was really like: Don’t expect Jan’s muscle-flexing snapshot 

I was nervously thrilled in anticipation of the most intense shark dive experience of my South African vacation.

The early wake-up call at 4.30 am and the two-hour boat journey were an extraordinary experience in itself. Once on the boat, it quickly becomes clear this won’t be a calm sightseeing trip.

But hey, the white shark won’t be waiting for you in the hotel lobby, right? So, two hours later I was welcomed by nice people offering breakfast followed by a short safety briefing.

 The crew will lead you through the entire process, from preparation to your time in the cage. BTW this activity is not suitable for every child, and even some adults may find the cold water and rough conditions challenging. Even with a wetsuit, the water feels cold within minutes.

Of course, in my head I already saw myself taming the shark instead of listening to the trainer.

You’ll also get all the gear you need for the cage dive, including wetsuits and masks—though calling it comfortable would be a stretch.

From pickup to drop-off, expect this to take anywhere from 6 to 10 hours depending on conditions and travel time.

How I was looking forward to swimming with this fellow here—gear on, confidence high! 

Shark Alley, the home of the great white shark and other marine life

All the participants were told during the safety training, that there are lollipops on the boat—a guaranteed cure for seasickness. Seasickness is very common on these trips; even people who usually feel fine on boats will likely struggle.

 That information was followed by loud laughter, water with a temperature of 12 °C (54 °F) and huge waves. 

A less experienced person might have been scared at this moment, but not me, Jan, who used to swim in the (surely much colder) Jizera river when he was young. I’m fearless.

Ready for the cage dive after a long boat ride to Shark Alley, the heart of great white shark territory

Everyone hopped on the deck and the boat anchored at Shark Alley, the place with the highest numbers of white sharks in the whole world—often referred to as the great white shark capital—where you can discover and observe them in their natural habitat.  

Shark sightings are very likely here, but never 100% guaranteed—it still depends on conditions and timing.

In contrast to destinations like Mexico, where different shark encounters are more common, this experience focuses purely on great whites.

The reality of shark diving no one tells you

In the beginning, the whole crew, including myself, was perfectly fine 
 

Would I write a diary, next entry would look like this: 

“After several warnings (and to my great surprise), there truly are waves on site. And huge ones. First people are starting to be sick, poor souls. Not me, though, I am never sick… not even at the worst, most challenging roller coasters. There are some desperate men that take the lollipops everyone laughed at. 

The others grin at the sick losers with lollipops in their hands. The seamen throw chunks of fish to the sea to lure the sharks. Thirty minutes later, all 20 tourists involved looked like this stock photo.” 

If you’re up for the challenge, you can join a shark cage diving tour here. 
 

Some of us were spotting sharks from the boat, others were contemplating their day trip choices 

Face to face with one of the ocean’s most powerful shark species 

The whole deck sits with lollipops in their mouths, some of us are throwing up and it takes dozens of minutes before the first two beautiful sharks arrive and we finally get to witness them up close.

Due to severe seasickness, I can’t help but ignore their beauty as well as my GoPro camera, bought solely to capture videos of this experience. 

My diary entry continues: 

“I wish I were back at shore. I was a fool to think that the nausea would be better in water. It isn’t. In fact, it’s even worse in the cage. 

Most of the time, you stay at the surface, just waiting for the moment the guide tells you to go under.

My spoiled-Czech feelings are pretty close to those in the picture below. I saw the shark several times and tried to observe it despite everything.However, due to my pitiful, frozen-to-death state and stomach discomfort I couldn’t do better than ignore it and focus on my suffering” 

Is shark cage diving similar to scuba diving?

No, shark cage diving isn’t scuba diving. You don’t get oxygen or anything—you just hold your breath and go under when a shark shows up.  You’ll be so shocked and maybe scared when you see it swimming around you, you’ll forget to need to breathe anyway. 

Final thoughts and would I go shark cage diving again?   

Believe me, the alternating vomiting and freezing cold water was not a picture-perfect part of my vacation.  Despite that, I came back excited and enriched by new, most intense and in a way also the best shark cage diving experience ever. And I would do it again without hesitation. 

Maybe it wasn’t totally what I had in mind, but it was definitely worth it and as a true hero, I regret nothing (except the breakfast maybe).
