About Duiker Island
Duiker Island is the Hout Bay seal colony stop: a tiny rocky islet where the main draw is close Cape fur seal encounters over a shallow, kelp-fringed anchorage in the island's lee. The bottom is granite and rock rather than sand, so the underwater plan is simple and the wildlife does the heavy lifting. Expect a short boat transfer, cold water and a busy marine-tour setting. It suits calm-day snorkelling or an easy scuba stop, but the real constraints are swell, boat traffic and a need to keep the channel clear.

Key Hazards
Safety Notes
Keep clear of the turnaround channel, expect cold wind on the boat, and watch for surge if the swell is south-westerly or very westerly.

Legal Notes
The site sits in the TMNP MPA and the Karbonkelberg headland area, so current marine rules and boat controls apply.
Local Intel For Duiker Island
Community notes to help plan your visit.
Scuba
Shallow boat dive over granite and kelp with seals overhead; keep the route simple and avoid the channel.
Freedive
Possible for confident freedivers, but the site is more of a seal snorkel stop than a dedicated breath-hold route.
Snorkel
This is the classic use case: short boat transfer, shallow water and close seal encounters when the sea is calm.
