Cape fur seals crowd the rocks at the base of the Robberg cliffs

The Robberg seal colony

Robberg means seal mountain. For most of the last century there were no seals on it. This is how they came back.

Where the colony is

The Robberg seal colony is on the northern, sheltered side of the Robberg Peninsula, about eight kilometres south of Plettenberg Bay. The seals haul out on the boulders and ledges at the foot of the cliffs, inside Robberg Nature Reserve and its Marine Protected Area.

From the hiking trail you look straight down on them from the cliff top. From the water you are level with them: hundreds on the rocks, and hundreds more rafting, porpoising and diving around the boat.

Gone for a hundred years

Early Dutch sailors named the headland Robbe Berg, seal mountain, for the animals that covered its rocks. Then sealers arrived. By the late 1800s, indiscriminate harvesting had wiped the colony out.

For most of the twentieth century Robberg was seal mountain in name only.

The return

In the 1990s, Cape fur seals began hauling out here again. Researchers who followed the recolonisation counted fewer than 300 animals in 2000 and more than 3 100 by 2009. They noted that the reserve and the Marine Protected Area around the peninsula helped the seals settle.

The colony has kept growing. In December 2024, CapeNature and Bitou Municipality put Plettenberg Bay’s seal population at about 8 000.

Why Robberg suits a seal

  • Shelter. The northern shore faces away from the prevailing south-westerly swell.
  • Food. The bay and the Agulhas Bank beyond it are rich fishing grounds.
  • Protection. The peninsula is a nature reserve, and the sea around it is a Marine Protected Area where boat fishing and spearfishing are not allowed.
