A scenic boardwalk leads to the viewing platform for Admiral’s Arch – the naturally formed rock bridge that towers above colonies of New Zealand fur seals.

Originally an ancient cave, Admirals Arch has been shaped by the intense winds and surf that pound the coast of Kangaroo Island. Stalactites still hang from the rocky ceiling whilst the floor has been eroded to a smooth finish. The Arch has been designated a geological monument, and is one of 27 geological monuments on the island.

The boardwalk runs along the cliff face, providing uninterrupted views of the ocean. Dolphins can often be spotted, and whales migrate along the coast from May to October. Year round entertainment however, is provided by the colony of fur seals that live and play on the rock platforms beneath the cliff. Pups are born in December, and remain with their mothers for a year, playing in the rock pools under the Arch.

Practical Info:

Sitting on Cape du Couedic in Flinders Chase National Park, Admirals Arch is a 10 minute walk from the Admirals Arch Car Park. Several longer walks such as the Cape du Couedic Hike begin within the area, and the Cape du Couedic Lightstation lies on the road to the Admirals Arch Boardwalk.
