Last Friday, while on a press trip to Hermanus to experience the beautiful boutique hotel 1 Marine Drive (more on that soon), I swapped dry land for the open ocean with Marine Dynamics, one of South Africa’s leading marine ecotourism companies based in Gansbaai.
Known for its responsible whale watching, Marine Big 5 cruises and shark cage diving experiences, Marine Dynamics offers visitors the chance to encounter some of the ocean’s most extraordinary wildlife while promoting conservation and education.
Our adventure began at The Great White House in Kleinbaai, where we received a safety briefing before being fitted with life jackets and waterproof jackets. We then boarded Dream Catcher, South Africa’s first purpose-built whale watching vessel. Spacious and incredibly comfortable, it’s designed to give everyone an excellent view of the action.
As we powered across the waves, the excitement on board was palpable. Our first stop was alongside one of the company’s shark cage diving boats, where divers waited patiently below the surface. While no great white sharks made an appearance, two curious bronze whaler sharks (also known as copper sharks) circled the boat, giving everyone a fascinating glimpse of these sleek and inquisitive predators.
From there we continued towards Dyer Island, an Important Bird Area located around 8km offshore. Home to one of South Africa’s endangered African penguin colonies, the island plays a vital role in protecting the only penguin species found on the African continent.

What I found especially interesting was learning about the penguins’ history. During the 20th century, their population declined by around 90%, largely due to egg harvesting, guano scraping and marine pollution.
Guano, the nutrient-rich layer of bird droppings that once covered the island several metres deep, provided penguins with natural nesting burrows that protected them from predators and harsh weather. After decades of commercial guano harvesting, much of that protective layer disappeared, forcing penguins to nest on exposed ground where they are far more vulnerable.

Just beyond Dyer Island lies Geyser Rock, home to an estimated 60,000 Cape fur seals. The stretch of water separating the two islands is famously known as Shark Alley.
Although the sharks stayed out of sight during our visit, the sheer number of seals bobbing around the rocks made for an unforgettable sight.

Our final destination took us further offshore in search of whales. It wasn’t long before someone shouted, “There!” and we spotted the unmistakable blow of a humpback whale. Seeing such an enormous animal surface just metres away is something no photograph can truly capture.
Humpback whales are celebrated for their spectacular breaches, haunting songs and remarkably long flippers, but it’s their quiet grace that leaves the greatest impression. Watching one glide effortlessly through the water in its natural habitat was nothing short of magical.
Before long, it was time to head back to shore, where warm butternut soup, fresh bread rolls and ginger beer awaited us — a welcome treat after a morning on the water, particularly for anyone whose sea legs hadn’t quite found their balance.
The Marine Big 5 experience is so much more than a boat trip. It’s a reminder of just how remarkable South Africa’s coastline truly is and why protecting these fragile marine ecosystems matters. I came away with a deeper appreciation for the incredible wildlife that calls our oceans home — and memories I’ll treasure for years to come.
