Seal Island is a small rocky island off the Western Cape coast of South Africa that supports a dense colony of Cape fur seals. It is best known for attracting large predatory sharks to the surrounding waters.

The site is notable for instances of great white sharks hunting by breaching the surface when pursuing seals in shallow water near the island. Wildlife-watch boat trips operate from nearby ports and are the usual way to observe the island and surrounding marine life.

The island itself is largely rugged rock with little vegetation and serves primarily as a haul-out and breeding site for seals. It lies off the coast of the Cape Peninsula within the marine environment of False Bay and adjacent ocean.

Seal Island sits offshore from the Cape Town metropolitan area and is visited from towns on the False Bay and Cape Peninsula coasts.

  • Wildlife: Home to a large colony of Cape fur seals and a focal point for viewing great white shark predation behaviour in nearby waters.
  • Access: Most visits are by boat tours launched from nearby coastal towns; approach distances and viewing conditions vary with sea state and operator.

Tips for Visiting Seal Island, South Africa #
