Why it's worth your time
Dyer Island and neighbouring Geyser Rock, off Kleinbaai near Gansbaai, are the launch point for the marine 'Big 5' — seals, great whites (and increasingly bronze whalers), southern right whales in season, dolphins, and a huge African penguin and seabird population. Trips run from Kleinbaai harbour. It's the gentler, better-value alternative to shark cage diving: you get the same waters and wildlife without being lowered into a cage. Visibility varies and the sea can be rough; pick a calm day and a reputable operator. In whale season, July to November, the boats often pass close to southern rights as well.
What we love
The variety — one boat, seals, sharks, whales and seabirds in a morning.
What to know
Sea conditions matter; the experience is much better on a calm day. Take motion-sickness precautions.
