Head from Cape Town to Gansbaai for a focused wildlife cruise around Dyer Island where you can encounter the Marine Big 5—whales, sharks, seals, penguins and dolphins—guided by an onboard marine biologist. This trip balances short, intense at-sea encounters with conservation-focused interpretation and an included visit to an African Penguin sanctuary.
