Introduction to Seal Island: Duiker Island is located in Hout Bay. It is famous for the large number of seals and seagulls on the island and is one of the famous tourist attractions on the Cape Peninsula. In order to protect these animals, tourists can only watch seals from a distance but cannot go to Seal Island. There are special yachts at the pier to take tourists to watch, and they will slowly circle very close to the island, allowing tourists to watch the seals hunting, playing in the water and inhabiting at close range.
