Nestled like a precious gem in the heart of Middle Island, the largest among the Recherche Islands forming the picturesque Recherche Archipelago off the southern coast of Western Australia, lies Lake Hillier. With its surreal pink hue, this captivating body of water stands as a marvel of nature, shrouded in mystery and fascination.
A Natural Wonder
Stretching about 600 meters in length and 250 meters in width, Lake Hillier is a sight to behold. Its shores are adorned with a rim of soft sand, embraced by a dense woodland of paperbark and eucalyptus trees. A narrow strip of sand dunes, lush with vegetation, separates its northern edge from the rugged coastline of Middle Island.
The Enigma of Pink
What makes Lake Hillier blush with such a distinct pink hue? The answer lies in the presence of an extraordinary organism called Dunaliella salina. This remarkable microorganism produces carotenoids, painting the lake with a mesmerising strawberry milkshake colour. Yet, the mysteries don’t end there. Some speculate that halophilic bacteria in the salt crusts or a reaction between salt and sodium bicarbonate could also contribute to the lake’s rosy tint.
A Tale of Discovery
Lake Hillier’s story stretches back to the early 19th century when British navigator Matthew Flinders stumbled upon its shores in 1802. After ascending the island’s highest peak, now fittingly named Flinders Peak, he gazed upon the lake’s rose-coloured waters. His journal entries stand as the earliest written records of this natural wonder, immortalising its beauty for generations to come.
Diving into the Unknown
Despite its high salt content, akin to the renowned Dead Sea, Lake Hillier beckons the adventurous at heart. With its crystalline waters, swimming in this natural wonder is an experience like no other. However, it’s essential to note that prior approval from the Western Australia Department of Environment Conservation is necessary, ensuring the lake’s preservation for future generations.
Journey to the Pink Oasis
Nestled in one of Western Australia’s most remote regions, Lake Hillier remains a well-guarded secret of nature. The closest town, Esperance, lies 77 miles away, offering a gateway to this pink paradise. Whether by air or sea, travellers seeking to uncover the mysteries of Lake Hillier can embark on an unforgettable journey, immersing themselves in its surreal beauty.
In the heart of Middle Island, where the sky meets the sea, Lake Hillier stands as a testament to nature’s boundless wonders. With its enchanting pink waters and untamed surroundings, it invites explorers to delve into the unknown, forging memories that will last a lifetime.
