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 Scenic Flight Services departing Esperance Airport several times a day but you cannot land on Middle Island. These can be booked here. There are no regular services to set foot on any of the Islands in the Recherche Archipelago with the exception of Woody Island.
Not far from the town of Esperance there is another lake, suggestively named Pink Lake, also known as Lake Spencer which has unfortunately lost all of its colour and has instead taken on a milky white colour.”
