Whale Watching near Cape Town, South Africa – Welcome to Gansbaai, home of the Marine Big 5.
Trip Summary 25 June 2026:
Even though the bay is still filled with some swell and wind, it has calmed down quite a bit and made it possible for us to head back out to sea! Leaving Kleinbaai Harbour behind us, we encountered a few diving birds, including some of the critically endangered African Penguins, looking for some fish. Next stop led us past our Shark cage diving vessel, Slashfin, where Bronze whaler sharks were circling the boat. Heading towards the island system, we made a pit stop alongside Dyer Island. Shortly after, we continued towards the Cape fur seal colony, where thousands of Cape fur seals were either relaxing on Geyser Rock or playing in the cool waters of Shark Alley. Lastly, we made our way into deeper waters, where two spouts were spotted in the distance. Heading closer, we could get our eyes on two Humpback whales travelling together towards warmer waters.

What species did we see today?

As one of only 17 penguin species left in the world (and the only one on the african continent), the african penguin often breed in offshore colonies, such as Dyer Island.
Cape fur seal Cape fur seal
With a local population of 60,000, it's no wonder our guests capture so many photographs of these wonderfully playful marine mammals.
Bronze Whaler Shark Bronze Whaler Shark
The Bronze whaler (also known as Copper sharks) here in Kleinbaai are very curious and interactive. These sharks eat mostly fish, with sardines being one of their favourites.
Humpback Whale Humpback Whale
One of the best-known whale species, they are renowned for their acrobatic behaviour and complex melodious song as well as extremely long flippers and are a special favourite of Dyer Island Cruises guests and crew alike.
