Lake Hillier is situated in quite a remote location, on an island, south of continental Australia, in the state of Western Australia.
Middle Island is the largest island of the so called Recherche Archipelago, but even so, it is only a bit over 4 miles (6.5 km) in length.
Only 6 miles to its north, the Cape Arid National Park can be found. Although it is located close to the continent, the nearest town is Esperance.
There are helicopter services to Middle Island but they cannot land there, but at least you can experience it from above. You can’t land on any of the Recherche Archipelago islands with the exception of Woody Island.
If your dream is to swim in a pink lake, not far from the town of Esperance there is another one called suggestively Pink Lake.
