More about Shark Cage Diving

Absolutely amazing!! We had so much fun. It was exhilarating and great to get so close to the sharks, and the staff was super nice, helpful, and informative. The food was also good and I felt I really got my money's worth.

Marine Dynamics were superb from the minute you contacted them, to the time you stepped off the boat. The staff were extremely accommodating and were dedicated to ensuring that everyone enjoyed the trip. They are a professional outfit and I would recommend them to anyone. We did two trips with this company and I wouldn't have returned if I hadn't been so impressed with them the first time. The whole operation is very slick and we thoroughly enjoyed our time with them. If you are thinking of doing cage diving in South Africa, then I wouldn't look any further than Marine Dynamics. They have the best facilities and the best staff. They helped me to tick off one of my most important items on my bucket list and I couldn't have asked for a better experience. We saw plenty of sharks and had plenty of opportunities to view them in their natural habitat. A special mention must go to Aletta and Kelly, I felt that both of them went the extra mile to help my partner and I to have a great trip. We really appreciated it. Many Thanks, Dave and Kate

We loved our shark cage diving experience with Marine Dynamics. They are very professional and gave us great customer service. The boat is big and clean. The crew will take care of you every step of the way. Big bonus, dry wetsuits!! Plus they feed you great breakfast and a light lunch. If you are not interested in getting in the water you will love taking photos from the top of the boat. Doing both is awesome and I will admit I was a little scared to start off with and realized I should have only feared the cold water :).Loved this adventure!

Briliant from start to finish. Met by staff sized up for suits provided really good breakfast and briefing. All clothing provided was clean and dry including coats and towels. Hot drinks and snacks on boat staff attentive and really encouraging especially to my daughter who is only eleven. She spent ages in the cage with her older brother. Not rushed in anyway and great interaction with sharks. The viz was not great but sharks up close and could see perfectly well above the water line. Back for a hot soup lunch with drinks and debrief really really great and have recommended to lots of people.
