An automatic lighthouse was built in 1906 at Cape Du Couedic (pronounced locally as 'cape de coodee') which was named by the French Captain Nicholas Baudin in 1802. Remnants of a jetty, water tank and storeroom can be viewed at nearby at Weir Cove. Many ships both large and small where wrecked at this portion of the Southwest.

Cape Du Couedic is located in an isolated corner of the Southwest end of the island in what is now Flinders Chase National Park. Scenically it is one of the most stunning places to visit. Gazing out to the Southern Ocean that pounds the precipitous coastline and over looking two islands known as 'The Brothers' and named the Casuarina Islets in 1802. These islets are a bird sanctuary and not accessible from the main island unless by boat and almost impossible to land on as they have sheer rock sides.

Beneath the point is a spectacular landform called Admirals Arch, a natural archway cut out by wind and water and pounded by towering seas. Seals and penguins can be seen nestling on the rock platforms around this location. From the platforms at the bottom of Admirals Arch you can see large colonies of Australian Sea Lions and New Zealand Fur Seals.  A walkway leads down to the stairs leading around the cliff face to the arch.

Cape Du Couedic has four lighthouse keeper houses, which are available for holiday rentals.

Weir Cove can be viewed from the Eastern side cliff tops where their supplies were hauled up the cliff face to the lighthouse. The small beach areas are also visible but unfortunately, they are at the bottom of very steep and large cliffs, which made it difficult - if not impossible to unload cargo destined for the lighthouse. A cutting was made into the cliff face on the western side of Weir Cove and a cable system rigged up. This was to haul the cargo up from the jetty at the base of the cliff. This "flying fox" cable system is no longer there, but from a cliff top vantage point it is obvious why it was required.
