I went on the shark cage excursion and at the last minute upgraded to swimming with sea lions. Marine Dynamics is a professional company with organization and efficiency rarely seen. The entire staff knows exactly what to do and everyone is very friendly and smiling, which creates a great atmosphere. The shark cage part was a bit below expectations due to poor visibility, so we didn’t see much marine life—the highlight was the bronze whaler. After leaving the cage, the team took us by boat for the sea lion swim. It was an incredible experience, far exceeding expectations. I want to thank our guide, Susy Alexandersen, who took great care of me knowing I can’t swim, as well as the entire sea lion team and the skipper who skillfully navigated the boat, for ensuring an unforgettable experience. I could have stayed in the water for hours, but even with wetsuits, the water wasn’t very warm. Thank you, Marine Dynamics—I will definitely return!

Being in South Africa, I would not miss shark cage diving. Marine Dynamics not only offers this amazing experience, but also does a great deal of conservation work related to sharks and other marine creatures. They use eco-tours to fund research and conservation efforts focusing on shark research, penguin and seabird rehabilitation, and community education. You can see that first hand at the Seabird Sanctuary located in Ginsbaai that provides care to sick and malnourished African Penguins on the Dyer Island. Most of the penguins who are cared for in the facility are released back to the wild. They are doing a truly wonderful work! I highly recommend!

Superb from start to finish! They have such a deep knowledge of the animals and they sync it perfectly with your time in the water so you're quite literally watching and learning. They were brilliant.

Loved the shark cage diving experience! Went out with a group of 30-40 people and had plenty of time in the water with the team providing snacks and nibbles on board whilst learning from a marine biologist. Lastly can't forget to mention the conservation work.

We feel very conflicted giving Marine Dynamics a 3-star rating as we know what a valuable job they do for shark and marine life in the area. We boarded the boat for our 3 hour shark cage experience, and frankly saw only a couple of rays in the water. It appears that sharks of any kind are rarely in the bay any more, it may be apocryphal, but someone mentioned that there hadn't been any sharks in the area for months. Whether that's true or not it was clear to us before we went on the trip we weren't going to see sharks, as it was made clear numerous times that 'there was no guarantee of any sightings but they will give you a voucher for a return visit if no sharks are seen'. That's great for locals but not for tourists. We of course accept it is a wildlife experience and you never know what you may see. Marine Dynamics do an excellent job, and I'm sure need the money from these trips to continue to do that great job. Perhaps though they need to change the name of the excursion to 'marine experience' rather than shark cage diving. Good luck to them though.

Had a great day! Upon receipt by the tour guide we received a clear explanation and safety briefing. We saw several sharks and along the way we got a lot of information about the sharks and their behavior. Fantastically arranged all. For anyone complaining about not seeing a White Shark...please read up on the situation of this shark species beforehand...

We had an absolutely fabulous shark cage diving and a separate whale watching experience with Marine Dynamics. I think anyone going on one of these have to understand that there are certain things completely out of the staff's hands i.e. frequency of sightings and sea visibility. However from what can be controlled by the team, from start to finish, the team went above and beyond to make sure everyone had a safe and enjoyable day. The guides were knowledgeable, passionate, and genuinely cared about our experience — including checking in on those who felt unwell from sea sickness, which was much appreciated. Seeing around eight beautiful bronze whaler sharks up close during our diving and during the whale watching tour managed to see about 6 Southern Right whales which was truly incredible and something we’ll never forget. The extra touches made the day even better — complimentary photos from the staff, a tasty breakfast before heading out, and warm soup afterwards. An unforgettable day with a wonderful team — highly recommended!

Really bad experience. The water was rough, large swells and very poor visability. You were thrown around in the cage due to the poor conditions. The captain was shouting at the lead chum person as they had got the chum mixture wrong. Very few sharks appeared over a couple of hours and the ones that did were only visible for a few seconds. Marine dynamics should review the sea conditions on the morning of the trip and give people the chance to cancel if they're likely to have a poor experience. This was supposed to be a once in a lifetime experience. Instead we were battered by waves in a cage, with chum thrown over us on several occasions and we probably saw 10 seconds of sharks. Half the people on the boat were sick due to the large swells. Really disappointed!
