Whale Watching near Cape Town, South Africa – Welcome to Gansbaai, home of the Marine Big 5.
Trip Summary 27 July 2025:
The east wind brought some life into the bay, and we were able to find humpback whales throughout the day. While watching the ocean giants, we spotted some pelagic seabirds as well. Along the coast, one of the trips was able to spot humpback dolphins very close to shore in front of Uilenkraalsmond. Around the shark cage diving boat, it was rather quiet, but the plenty of Cape fur seals made up for it, and we also found some penguins on Dyer Island.

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

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.
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.
