The most famous of these is Lake Hillier, located on Middle Island in the Recherche Archipelago off the coast of Cape Aride, east of Esperance. Other well-known pink lakes in Western Australia include Hutt Lagoon, Lake Warden, Lake Eyre, Lake Bumbunga, and Lake Hart. These lakes get their distinctive pink hue from a combination of factors, including high salt concentrations, specific types of algae, and bacteria. The colour of the lakes can vary depending on the season, time of day, and weather conditions, ranging from delicate pink to deep purple.

What You'll Learn
Lake Hillier, Middle Island
Western Australia is known for its pink lakes, which are a result of high salt content and the presence of the Dunaliella salina microalgae. One of the most famous pink lakes in the region is Lake Hillier, located on Middle Island in the Recherche Archipelago, off the south coast of Western Australia. The lake is about 600 metres long and 250 metres wide, and it is surrounded by a rim of sand, eucalyptus and paperbark trees, and the deep blue ocean. The vibrant pink colour of the lake is permanent and does not alter when the water is taken in a container, although it is less noticeable when viewed from the surface.
Lake Hillier was first discovered in 1802 by navigator and cartographer Matthew Flinders, who ascended the island's highest peak (now called Flinders Peak) and observed the pink lake. Flinders also noted the high salt content of the lake, which was later subject to salt mining in the late 19th century. However, the enterprise failed due to the toxicity of the salt collected for consumption. Today, Lake Hillier is a popular tourist attraction, accessible mainly by air tours and boat cruises. Scenic flights depart six times a day from Esperance Airport, offering stunning views of the lake and the surrounding area, including Cape Le Grand National Park. Cruises are also available for those who want to view the isolated lake and surrounding forest.
It is important to note that visitors are not allowed to disembark on Middle Island. Swimming in Lake Hillier is safe, despite the high salt content, and the water is clear and harmless to human skin. The Dunaliella salina algae found in the lake are also completely harmless. The unique pink colour of the lake is believed to be due to the presence of Dunaliella salina, a type of microalgae that thrives in highly saline environments and produces carotenoid red pigments. However, the exact reason for the lake's colour is still not fully understood by scientists.
Lake Hillier is not the only pink lake in Western Australia or even in Australia. There are dozens of vibrant pink and rainbow lakes in the Esperance region, ranging from pastel pink to sparkling orange and deep red. Hutt Lagoon, located less than a six-hour drive north of Perth, is another notable pink lake in Western Australia that changes colour from red to pink to purple depending on the season, time of day, and cloud coverage. Other accessible pink lakes in Australia include Lake Bumbunga, located less than a two-hour drive from Adelaide, and Lake MacDonnell in South Australia's Eyre Peninsula.

Hutt Lagoon, Coral Coast
Western Australia is known for its vividly hued nature, including its pink lakes. One of these is the Hutt Lagoon, located in the Coral Coast region of Western Australia. The lagoon is a salt lake with a red or pink hue, which is caused by the presence of carotenoid-producing algae Dunaliella salina, a source of β-carotene, a food colouring agent, and vitamin A. The lagoon is also a site for the commercial production of Artemia parthenogenetica brine shrimp, which is used as a specialty feed for prawn and fish farmers and the aquarium fish trade.
Hutt Lagoon is located at Port Gregory, just over an hour's drive north of Geraldton or 45 minutes to an hour south of Kalbarri. It can be easily accessed by road, and there is a dedicated (unsealed) Pink Lake Lookout on Port Gregory Road, where visitors can pull over, park, and explore. Alternatively, visitors can stop along George Grey Drive, though they must allow enough time to safely pull over and park off the road. There are also multiple tour options available, including guided buggy tours from Port Gregory and guided coach tours from Geraldton or Kalbarri. For those seeking aerial views of the lake, scenic flights are offered from Geraldton or Kalbarri.
The lagoon covers an area of approximately 70 square kilometres, with most of it lying a few metres below sea level. It is separated from the Indian Ocean by a beach barrier ridge and barrier dune system. The village of Port Gregory is located near the mouth of the Hutt River, which was originally developed to serve the Geraldine Mine—the first site for mining in Western Australia. Today, Port Gregory is a popular holiday destination for fishing and diving, and the surrounding area features a pinkish, garnet sand that is a popular spot for picnicking, kayaking, and pelican spotting.
The Coral Coast region is known for its colourful nature, with red cliffs and bright blue waters. The Pink Lake at Hutt Lagoon is one of the region's highlights, offering a unique spectacle of colours that change from red to pink or purple depending on the season, time of day, and cloud coverage. The best time to visit the lake to catch its colourful spectrum is during mid-morning or sunset.

Esperance's Pink Lake
Esperance, a gorgeous beach town in Western Australia, is known for its pink and rainbow lakes. The Esperance Pink Lake Tourist Park is a popular destination for families and nature enthusiasts, offering a range of accommodation options and natural wonders to explore. However, it is important to note that the famous Pink Lake in Esperance has lost its vibrant pink hue. While it was once a vivid pink, attracting travellers and locals alike, the lake has not been pink for several years. This colour change is attributed to salinity alterations caused by human activity.
The Pink Lake in Esperance was previously known as Lake Spencer and is located in the Goldfields-Esperance region. It is situated about 3 kilometres west of Esperance and used to be a popular tourist attraction due to its distinct pink colour. The pink hue was a result of the high salt concentration in the lake, which, along with external changes and weather conditions, played a crucial role in determining the colour of the water. The lake's colour could vary from pastel pink to sparkling orange and deep red, depending on various factors.
The loss of the pink colour in Esperance's Pink Lake has led to proposals to either change the name of the lake and the town back to Lake Spencer or find a way to alter the salinity to restore its distinctive pink shade. The surrounding area, arterial road, and local businesses initially adopted the name Pink Lake, and the lake was a significant attraction for tourists visiting Esperance. However, with the lake no longer displaying its famous pink colour, visitors have expressed disappointment.
Despite the loss of its pink hue, Esperance's Pink Lake still offers a serene and naturally captivating experience. The lake has been identified as an Important Bird Area by BirdLife International due to the significant populations of hooded plovers and banded stilts that it supports. The lake is surrounded by pristine beaches, national parks, eco-tourism options, historic sites, and the Esperance foreshore, providing a diverse range of attractions for visitors. Scenic flights are also available, offering a unique perspective of the lake and the surrounding landscapes.

Lake Bumbunga
While Western Australia is known for its pink lakes, Lake Bumbunga is located in the state of South Australia. It is a salt lake situated between the town of Lochiel and the farming locality of Bumbunga, approximately 125 kilometres (78 miles) or a 1.5-hour drive from Adelaide. Covering 15 square kilometres (5.8 square miles), it is easily visible from Highway 1 for a distance of 10 kilometres (6.2 miles).
The lake's unique colour is due to the presence of algae, specifically Dunaliella salina, which thrives in salty environments. Salt has been mined at Lake Bumbunga almost continuously since 1881, and it has become a significant tourist attraction. The lake features a "Loch Eel Monster" sculpture in the middle, adding to its appeal. The name "Bumbunga" is derived from the word "parnpangka" in the local Aboriginal language (Kaurna), meaning "rainwater lake". The lake lies in the traditional lands of the Kaurna people.
While Lake Bumbunga is a popular destination for its striking visuals, some visitors have noted the presence of flies and a pungent odour in the area surrounding the lake. It is recommended to check the latest images posted on social media to gauge the pinkness of the lake before travelling there.
