Whale Watching near Cape Town, South Africa Welcome to Gansbaai, home of the Marine Big 5.
Trip Summary 16 May 2026:
With some slight east wind coming into the bay, we left Kleinbaai Harbour behind us. Heading down the coastline, we passed the natural estuary and moved towards our Shark cage diving vessel Slashfin. Our regulars, the Bronze whaler sharks were already cruising passed the boat on our arrival. Continuing our trip through the reef system, we also introduced our guests to our kelp forest. Geyser Rock with its Cape fur seal colony did not disappoint, as thousands of individuals welcomed us with their loud vocals. Penguins were either seen on the island but also out at sea. In deeper waters, once again, we came across a sunfish. On top of that, a Humpback whale was putting on a show by breaching!

With a local population of 60,000, it's no wonder our guests capture so many photographs of these wonderfully playful marine mammals.
