5-day fun trip to the pink waters of Lake Hillier – Tiasa and’s eyes

Wanted to get away from the hustle and bustle of Melbourne’s busy city and get close to nature. Tiasa had already said, “Go on a trip!” Our destination is Lake Hillier – the famous pink lake on the west coast of Australia. Needless to say, the colour looks like someone poured pink paint on the canvas.

Day 1: Depart from Melbourne

Our journey begins with a flight from Melbourne. The flight takes about 4 hours, and costs about $350 (往返) per person. We arrived via Perth to the city of Esperance, and from there, we took a helicopter ride to Lake Hillier.

• Transport Cost: The flight and helicopter total cost about $1200 for the two of us.
• Accommodation: Booked a nice Airbnb in Esperance, $130 per night — $650 for 5 nights.

The first da,y we just wandered around the town of Esperance. Walked along the sea-bridge, and Tiasa kept saying, “The air here smells so different and fresh!”

Day 2: First visit to Hillier Lake

This day was one of the most exciting days of our lives. We boarded the helicopter to fly over Lake Hillier. The pink water of the dream came into view! The pink lake in the middle of the dark green trees is like a wonderful wonder of nature. Can’t go down, so I saw from above. But the experience is incredible.

Tiasa was so excited sitting in the helicopter, saying over and over, “It’s scary and it feels good!” We laughed so hard that the pilot himself laughed.

Day 3: Beach, Coffee and Cold Bridge

This day was spent relaxing. We went to Twilight Cove and Lucky Bay. I saw a kankoala like a koala in Lucky Bay! Tiasa saw a kangaroo and said, “Hey baby kangaroo!”

Sat on the beach and drank coffee, took some pictures, and made a drone video that is still going viral on our Instagram. Travelled by rental car — car rental $60 per day, $300 total.

Day 4: Local food and market

Tiasa said, “If I don’t eat the food of the place I’m going to, does the trip end?” So I went to a local kitchen restaurant — had grilled barramundi and Queensland prawns. The cost was roughly $80.

Then I went to the local handicraft market. Bought pink lake-themed earrings and a wooden photo frame – to decorate back home in Melbourne.

Day Five: Farewell Morning

When it was time to go back, I was upset. Tiasa was saying, “Wouldn’t it have been another day?” I was also silent. Truly, the kind of peace, laughter and natural beauty I experienced in ese 5 days — is completely invimechanisedhe mechanized life of the city.

How was the environment and the people?

From the helicopter pilot to the restaurant waiter — everyone was super friendly. No arrogance anywhere, just wanting to help. The environment was crystal clear, fresh air, blue sky and bird calls always accompanied by a background score like a movie.

Did something go wrong?

Only one problem — I got Tia’s bag a little late at the airport. It was a bit of a bummer, but it was fixed within 2 hours, and we breathed a sigh of relief.

What do you like the most?

The best moment for both of us was the helicopter ride over Lake Hillier. The sight of that pink water, before our eyes, it seemed as if we were in a dream.

What else did you want to do?

I wanted to get off the helicopter and sit by the lake. But that was prohibited, as visitors cannot go to the lakeside due to environmental protection. But what I saw from above, my mind is full.

Lake Hillier was a chapter in our lives that we will remember again and again. The beauty of the pink lake, Tiasa’s smile, and some private moments between the two of us — these are the real gems of life!

What is Lake Hillier, and where is it located?

Lake Hillier is a stunning, pink-colored lake located on Middle Island, the largest island of the Recherche Archipelago off the coast of Western Australia. This unique natural wonder is located near the south coast of the country within the Goldfields-Esperance region.

What makes Lake Hillier different from other lakes?

The most distinctive feature of Lake Hillier is its permanent pink colour, which remains vibrant throughout the year. Unlike other pink lakes that change shade based on environmental factors, Lake Hillier’s colour remains consistent due to its unique chemical and biological makeup. The lake’s high salinity level and the presence of specific microorganisms make it an unusual and scientifically interesting water body.

When and how was Lake Hillier first discovered?

Lake Hillier was first documented in 1802 by British navigator and cartographer Matthew Flinders when mapping the Australian coastline. He recorded his observations in his journal, noting the lake’s striking pink hue. Since then, Lake Hillier has become a subject of fascination for scientists, travellers and nature enthusiasts.

2. Geographical and natural features

What are the size, depth, and shape? Lake Hillier?

Lake Hillier is about 600 meters (2,000 ft) in length and about 250 meters (820 ft) in width. Although its depth varies, it is relatively shallow compared to other natural lakes. The lake is oval and is located near the coastline of the central island.

What is the surrounding environment and geological landscape?

The lake is surrounded by dense forests of eucalyptus and pepperbark trees, which create a striking contrast against the bright pink water. Beyond this green boundary, the island has sandy beaches and rugged coastal cliffs, giving the area a varied and picturesque landscape.

Is Lake Hillier connected to the ocean, or is it completely isolated?

Although Lake Hillier is located near the Southern Ocean, it is completely isolated from direct ocean water flow. A narrow strip of land separates the lake from the ocean, and despite their proximity, the lake maintains its high salinity and unique characteristics without mixing directly with seawater.

3. The science behind the colour pink

What chemical or natural element is responsible for the pink colour of the lake?

The pink colour of Lake Hilia is mainly due to the presence of certain microorganisms and chemical compounds in its highly saline water. Key contributors include:

• Dunaliella salina – a type of algae that grows in high salinity environments and produces red pigments called carotenoids.
• Halobacteria (halophilic bacteria) – These salt-loving microorganisms contain pink-red pigments, which intensify the distinctive colour of the lake.
• High salt concentration – The lake’s high salinity enhances the effect of these microorganisms, helping to maintain its vibrant hue.

How do Dunaliella salina and halobacteria contribute to lake colour?

Dunaliella salina produces beta-carotene, a pigment that absorbs light and gives the reddish-pink colour. Meanwhile, halobacteria contain bacterioruberin, a pigment that also enhances the pink hue of water. The interaction between these microorganisms and the lake’s high salt levels creates a stable pink colour that remains visible even when the water is collected in a container.

Does the colour of the lake change with the seasons or weather?

Unlike other pink lakes that change shade depending on temperature, salinity and rainfall levels, Hillier Lake maintains its pink colour throughout the year. However, during periods of extreme environmental change, slight variations in intensity may occur, but the lake never completely loses its signature pink hue.

How does Lake Hillier compare to other pink lakes like Lake Retba in Senegal?

Lake Hillier is often compared to Senegal’s Lake Retba (Lac Rose), another well-known pink lake. However, there are key differences:

• The color of Retba lakdependingtes Depending on the time of day, evaporation rate and salt concentration, Lake Hilia maintains a constant pink shade.
• Retba Lake Salt Extraction Industry is affecting its ecosystem, whereas Lake Hillier remains largely intact.
• Lake Hillier is isolated and protected, making it a more pristine natural wonder, while Retba Lake is actively used for commercial purposes.

 Chemical and biological properties

What is the salinity level of Lake Hillier, and is it saltier than the ocean?

Lake Hillier is a hypersaline lake, meaning its salt concentration is significantly higher than that of seawater. Where the average salinity of sea water is approx 3.5% (35 grams of salt per litre of water), it may exceed the salinity of Lake Hillier ৩৫%, making it nearly ten times saltier than the ocean in some areas. This extreme salinity is a key factor. Why lakes support unique microorganisms, viz Dunaliella salina and Halobacteria, which contributes to its pink color.

Is Lake Hillier’s water safe for human consumption?

Despite its visually appealing pink colour, Hillier Lake water is not fit for drinking Due to extremely high salt content and presence of certain bacteria. However, water itself is non-toxic, meaning brief exposure, such as touching or swimming, is not harmful. Unlike the Dead Sea, where the high salt concentration allows people to float easily, Hillier’s waters are generally not open to public swimming due to conservation efforts.

How does high salt concentration affect lake biodiversity?

High salinity levels create extreme environments, making it difficult for most aquatic organisms to survive. Although preferred by salt-tolerant microorganisms, Dunaliella salina and Halobacteria Prosper in this abode. Larger aquatic organisms, such as fish and amphibians, cannot survive due to osmotic pressure. The extreme conditions prevent the development of a diverse ecosystem within the lake itself, but some microorganisms have adapted to these harsh conditions.

5. Ecosystems and Biodiversity

What kind of microorganisms and bacteria live in Lake Hilia?

Primitive life forms occur in Lake Hillier. Halophilic (salt-loving) microorganisms have adapted to their extreme environment. The two main contributors to lake ecosystems are:

• Dunaliella salina (Microalgae): These unicellular algae grow and produce in hypersaline, environments Carotenoid pigments, giving the lake its pink hue.
• Halobacteria (salt-loving bacteria): These contain archaea Bacterioruberin, a red-pigmented protein that helps them survive in extremely salty conditions.

What plants or animals can survive in this environment?

Due to the extreme salinity of the lake, Fish and larger aquatic species cannot survive. However, microorganisms present in water adapt to such harsh conditions. In contrast, the surrounding environment of the central island supports A diverse range of plant and animal life, including Eucalyptus trees, paperbark trees and coastal shrubs.

What kind of flora and fauna are found around Lake Hilia?

Although the lake lacks complex life forms, nearby island ecosystems are home to a variety of species, including:

• Bird: The middle island serves as a residence for sea ​​birds and migratory birds.
