Lake Hillier is an amazing and unreal pink-colored lake and is one of nature’s most fascinating occurrences. As individuals living on this earth, we have always seen bodies of water, such as different lakes, rivers, and ponds, all of blue color.

However, there is just one and only pink lake in Australia, the Lake Hillier.

It is a saline lake located on Middle Island. Middle Island is the largest of the Recherche Archipelago islands located off the shore of the south coast of Western Australia. A long and thin strip separates Lake Hillier and the Southern Ocean. 

Where we know lakes and water bodies are blueish, we have Lake Hillier, which is in vibrant pink color! It is one of nature’s most fascinating occurrences. 

The bubble gum pink lake has made many scientists, researchers, and tourists interested in it. It is one of the world’s most unique and mysterious natural wonders.

The lake remains a subject of mystery for many people.

1. Features of the Bubble Gum Pink Lake

The pink Lake Hillier is about 600 meters long and about 250 meters wide.  The thick forest of eucalyptus and the trees of paperbark surround the lake.

Its northern side is separated from the Northern shore of Middle Island by a thin strip of dunes of sand that are covered with vegetation. The most notable and distinguishing feature of Hillier Lake is its pink color.

Moreover, the vibrant pink color of the lake does not fade or vanish even when the lake water is taken into a container.

2. How Was the Rose-Colour Lake Discovered?

Matthew Flinders first discovered the lake. He was a cartographer and a navigator. He was the first one to visit the lake. On January 15, 1802, Flinders found the pink Lake Hillier on his journey.

Flinders saw the pink lake on his way to the Middle Island’s highest peak (now called Flinders Peak). He observed it and said that the small lake of rose color fascinated him. 

It was known that the lake’s saturated salt made the lake pink. He stated the existence of pink Lake Hillier in his journal from the sample he took from the lake.

The lake was named after William Hillier, a crew member from the Investigator.  William Hillier lost his life before the journey of Flinders began in 1803 when he visited the lake for the second time. Matthew Flinders named it.

In the 19th century, there was great curiosity among different researchers and scientists in the pink lake. There was a growing interest in extracting salt from the lake.

However, the mining enterprises that extracted the salt were known to have been failing because of the consumption toxicity of the salt that was collected.

3. The Mystery of the Pink Colour

The most defining and breathtaking feature of Hillier Lake is its pink color. Lake Hillier amazes us by maintaining its bubble gum pink vibrant watercolor.

It has been a constant matter of interest and excitement why the color of this lake is pink. The beautiful, shiny color of Hillier Lake attracts many tourists and visitors from all over the world.

3.1 Scientific Explanations

There has been a lot of research and scientific explanation that comes into play. Furthermore, several hypotheses and theories have tried to explain the color’s origin.

One important theory suggests that the pink color results from the highly saturated salts in the water of Lake Hillier. In addition, microorganisms, such as microbes, are found in the water.

Some microorganisms, such as Dunaliella salina and Halobacteria, are said to be present in the water of Lake Hillier. The pink color of Lake Hillier is a natural process.

It cannot be assured due to the variations in the lake.

Another theory is that large, bright blue waters separate Lake Hillier. It is because of this reason that the pink Lake Hillier collects certain bacteria and microorganisms that are only found here.

3.2 Some More Explanations

There have been many theories and explanations regarding the pink color of Lake Hillier. However, the exact phenomena of the color of the lake still remains a mystery.

The view from the surface shows less focus on the pink color. The pink color is highlighted from the top or when seen from above.

However, Lake Hillier is more saturated in color pink than other pink lakes worldwide.

Lake Hillier was used to extract salt crusts for some years. Nowadays, Lake Hillier is mainly used by tourists and as a tourist attraction.

Even with the unusual hue, the lake does not show any harmful effects on humans.

4. The Environment Around the Lake

The Lake Hillier is one of the most beautiful-looking lakes. It is also a highlight of the Middle Island, which is a part of the Recherche Archipelago. The geology and environment around the lake is the one where everyone cannot stop appreciating it.

The eucalyptus trees and paperbark trees surround the island, making it a lush green vegetation.

The rich green color contrasts with the vibrant pink color, giving an incredible sight. This natural and beautiful contrast attracts a lot of attention from people. You can enjoy the contrast and capture some fantastic pictures!

4.1 Isolated Location

The Middle Island of the Recherche Archipelago is located at a unique location. It is not connected to any large or big landmass. This might be another factor or reason for the color of the pink Lake Hillier.

Since the exact reason for the pink hue of the lake is unknown, many researchers assume that it may be due to a combination of things. A combination of microorganisms with the environment and geology of the lake, along with the climatic conditions, may act as a reason for the pink color.
