Pink Lakes in Western Australia: Hutt Lagoon, Lake Hillier and How to Visit in 2026

Western Australia is home to some of Australia's most unusual natural landscapes, including lakes that can appear pink, rose-coloured, or even reddish depending on their environmental conditions. These striking colours attract photographers, nature lovers, and travellers looking for something different from the country's familiar beaches and city attractions.

Two of the most talked-about examples are Hutt Lagoon, near Port Gregory on the Coral Coast, and Lake Hillier, on Middle Island in the Recherche Archipelago near Esperance.

Although both are known for their unusual colours, they offer very different travel experiences. Hutt Lagoon is accessible by road, making it a practical stop on a Coral Coast road trip. Lake Hillier is much more remote and requires careful planning because it sits on an island off the southern coast.

There is also an important detail for anyone planning a 2026 trip: Lake Hillier's famous pink colour is not guaranteed to be visible today. Tourism Western Australia notes that the lake's colour has changed, and a local cruise operator reports that heavy rainfall turned the water brown. Hutt Lagoon's colour also changes with natural conditions.

This guide explains where to find these lakes, what causes their colours, how to plan a visit, what to photograph, and how to explore the surrounding region responsibly.

1. What Are Pink Lakes and Why Do They Change Colour?

Pink lakes are saline or salt-rich bodies of water that can develop unusual colours because of microorganisms, pigments, mineral conditions, and environmental factors.

The colour is not necessarily permanent. Depending on the lake, changes in salinity, water levels, sunlight, temperature, and biological activity can influence whether the water looks pink, orange, red, purple, or less colourful.

The role of salt-loving microorganisms

Some pink lakes contain microorganisms that thrive in highly salty environments. Certain algae, including Dunaliella salina, can produce pigments that contribute to reddish or pinkish colours. Salt-loving microorganisms such as halophilic bacteria can also play a role.

However, the exact cause of a lake's colour can vary. It is not accurate to assume that every pink lake has the same biological explanation.

Why the colour can change

Several factors may affect a lake's appearance:

• Salinity: The concentration of dissolved salt can influence which microorganisms thrive.
• Rainfall: Heavy rain can dilute the water or carry sediment into a lake.
• Water levels: Changes in depth can affect how light interacts with the water.
• Sunlight: The angle and intensity of sunlight can alter how colours appear in photographs.
• Biological activity: Microorganisms and their pigments can change with environmental conditions.

This is why an old photograph of a bright pink lake may not reflect what a visitor sees on the day of arrival.

2. Hutt Lagoon: A Pink Lake You Can Visit by Road

Pink lakes are natural bodies of water that can develop unusual shades of pink, red, orange, or purple. These colours are often associated with high salt concentrations, microorganisms, pigments, and environmental conditions.

Some salt-loving microorganisms produce pigments that can influence the colour of the water. The algae Dunaliella salina, for example, can produce reddish-orange pigments under certain conditions. Salt-tolerant microorganisms may also contribute to the appearance of some saline lakes.

However, not every pink lake gets its colour in exactly the same way. The chemistry and biology of each lake can differ, so a single explanation does not necessarily apply to every location.

Why does the colour change?

A lake's appearance can vary throughout the year and even during a single day.

Several factors can influence its colour:

• Salinity: Salt concentration affects the organisms that can survive in the water.
• Rainfall: Heavy rainfall may dilute the water or introduce sediment.
• Water levels: Changes in depth can alter how light interacts with the water.
• Sunlight: The angle and intensity of sunlight affect how colours appear.
• Biological activity: Microorganisms and their pigments can change with environmental conditions.

These factors explain why a lake may appear bright pink in one photograph but pale, reddish, or brownish in another.

For travellers, the main takeaway is simple: pink lakes are natural environments, and their colours cannot be guaranteed.

2. Hutt Lagoon: One of Western Australia's Most Accessible Pink Lakes

Hutt Lagoon is one of the most recognisable natural attractions on Western Australia's Coral Coast. Located near Port Gregory, the lagoon is known for its changing shades of pink, lilac, red, and sometimes purple.

Its appearance can vary depending on the season, time of day, and weather. Tourism Western Australia notes that the lagoon's colour is influenced by its highly saline waters and that visitors can view it from locations along Port Gregory Road.

Where is Hutt Lagoon located?

Hutt Lagoon lies near the coastal settlement of Port Gregory, north of Perth.

It is commonly included in road trips between Perth, Geraldton, and Kalbarri. According to Tourism Western Australia, the drive from Perth takes just under six hours, while Kalbarri is approximately 30 minutes away by road. Actual journey times depend on traffic, stops, and the route selected.

What makes Hutt Lagoon special?

Hutt Lagoon stands out because it combines unusual colours with relatively straightforward road access.

Visitors can:

• View the lagoon from suitable roadside locations.
• Photograph its changing colours and surrounding landscape.
• Include it in a Coral Coast road trip.
• Explore nearby Port Gregory and Kalbarri.
• Consider a scenic flight for a broader aerial view, subject to availability.

The lagoon's colours are a natural phenomenon. Visitors should not expect the same shade shown in every travel photograph.

Best time to visit Hutt Lagoon

Tourism Western Australia recommends visiting on a clear day, particularly around mid-morning or sunset, when the colours may be especially striking. The lagoon can also change with the seasons.

For the most enjoyable experience:

1. Check the local weather forecast.
2. Allow enough time to explore the surrounding area.
3. Choose safe, permitted viewing locations.
4. Avoid entering restricted land or fragile salt surfaces.
5. Keep in mind that the lake may look different from online images.

3. Lake Hillier: The Famous Pink Lake Near Esperance

Lake Hillier is located on Middle Island in the Recherche Archipelago, off the southern coast of Western Australia near Esperance.

The lake became internationally famous for its distinctive pink appearance. From above, its water contrasts with the surrounding vegetation and the blue ocean, creating a striking natural landscape.

Lake Hillier is approximately 600 metres wide and is located around 11 kilometres from the coast of Cape Arid National Park.

Why is Lake Hillier famous?

Lake Hillier was recorded by explorer Matthew Flinders in 1802. Its unusual colour and remote island location have made it one of the most recognisable natural landmarks in Western Australia.

However, the lake's appearance has changed over time.

Tourism Western Australia currently notes that Lake Hillier is no longer consistently the vivid bubblegum pink shown in many historic photographs. Its colour is a natural phenomenon and cannot be guaranteed.

This is an important consideration when planning a visit in 2026.

Can you visit Lake Hillier?

Lake Hillier is not a typical roadside attraction. It is located on a remote island, so visitors need to plan transport and access carefully.

Depending on current availability, viewing options may include:

• Scenic flights over the island.
• Organised boat-based excursions.
• Other authorised experiences offered by local operators.

Access arrangements, weather, and conservation requirements may affect what is possible. Confirm the exact itinerary and viewing arrangements before booking.

What should you check before booking?

Before arranging a Lake Hillier excursion:

• Ask whether the lake is visible from the planned route.
• Confirm whether the trip includes an island landing or only an aerial view.
• Check departure locations and total journey time.
• Review weather-related cancellation policies.
• Follow all environmental and access restrictions.

The lake's colour may differ from the images used to promote the destination, so plan to enjoy the wider island landscape as well.

4. Hutt Lagoon vs Lake Hillier: Which One Should You Visit?

Both lakes are worth learning about, but they suit different travel plans.

Hutt Lagoon: Ideal for a Coral Coast road trip

Hutt Lagoon is a practical choice for travellers who want to explore Western Australia by car.

It can be combined with:

• Kalbarri National Park.
• Port Gregory.
• Coastal viewpoints along the Coral Coast.
• Other regional attractions between Perth and Kalbarri.

Because it is accessible by road, travellers can include it in a flexible itinerary and adjust their plans according to weather and local conditions.

Lake Hillier: A remote island experience

Lake Hillier is better suited to travellers who are already visiting Esperance and want to arrange a specialised excursion.

The journey requires more planning, and availability can depend on weather, transport, and access conditions.

Its remote setting and surrounding island landscape are part of the experience, even if the water is not bright pink.
