Whale Watching near Cape Town, South Africa – Welcome to Gansbaai, home of the Marine Big 5.
Trip Summary 29 April 2025:
We started today’s tour at Danger Point and were heading through deep waters. After a search for wildlife in the deep waters, we stopped at the Cape fur seal colony and got to see plenty of them. At Dyer Island, we had some looks at penguins and cormorants before moving on to the shark cage diving boats. First, it seemed quiet, but we ended up seeing a Seven-gill shark a few times. Shortly after leaving the sharks behind us, we saw more penguins and found a small pod of Indian Ocean humpback dolphins.

What species did we see today?
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.
African Penguin African Penguin
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.
Indian Ocean Humpback Dolphin Indian Ocean Humpback Dolphin
Humpback dolphins are an endangered species, with small populations living very close to shore, typically in water less than 25m deep and an average home range of 120km. Their proximity to land makes these animals particularly vulnerable to human influence.
Giant Petrel Giant Petrel
Around the Greater Dyer Island area we encounter both species of Giant Petrel, the Southern Giant Petrel and Northern Giant Petrel.
