Why dive here
With 269+ marine species recorded in the area - including blue sharks, blue whales, dolphins, dwarf minke whales and great white sharks - Duiker Island offers some of Cape Town & Western Cape's richest reef diving. Water ranges 14-16°C, warmest February, March, April.
Duiker Island, or as everyone calls it, Seal Island, is exactly what it sounds like – a chaotic, joyful tumble with hundreds of Cape fur seals. Forget quiet observation; this is an immersion. The water here feels electric, buzzing with the seals darting past, sometimes nudging your fins, their whiskers brushing your mask. We love how interactive it is, a proper sensory overload with the sound of their barks carrying even underwater, muffled but still there. The max depth is only 9 metres, so it’s a brilliant spot for newer divers, but honestly, even the most jaded among us get a kick out of it. The granite boulders are coated in thick kelp, and while the visibility averages around 6 metres, that just adds to the wild, slightly disorienting feel as seals appear and disappear from the gloom. Look out for pyjama sharks cruising the edges of the kelp, and the occasional shy cowfish peeking out from behind a rock. We’d suggest going on a calm day; even a slight swell can make for a bumpy ride in, but it’s always worth the jostle for the sheer joy of diving with these guys. Duiker is a truly unique experience, a playful chaos that stays with you long after you’ve toweled off.
