Duiker Island is very small, sitting in Hout Bay, home to an abundant variety of wildlife. The island is sometimes known as Seal Island due to the large population of fur seals that is often found there, and the area is also home to sea birds.
The island itself isn't even one acre, so visits are not usually very long. There are several daily cruises out to the island, however, so you can see the seals and birds up close—either from the boat or from the island. Hout Bay is also known for diving.
Duiker Island is roughly 13 miles from Cape Town. Don't confuse this Seal Island with the other Seal Island in False Bay.
