Western Australia’s spectacular landscapes are known to draw international tourists from far and wide, but none are as bright and unique as the pink lakes scattered throughout our state.
They’re weird, wonderful, and make for incredible photo opportunities, but where are these pink lakes and why are they so pink?
What makes the pink lakes so pink?
While the precise conditions that create each lake’s shade can vary, scientists agree that the colour comes from a combination of high salinity, light, and pigmented microorganisms such as Dunaliella salina and Halobacterium salinarum
With high salinity (many of the lakes are very close to the ocean), the salt concentration can reach levels much higher than that of sea water, and with lots of light — which, of course, WA has a lot of, the algae and archaeon take on a pigment called beta-carotene, the same pigment found in carrots. Its colour? You guessed it. Pink. These lakes turn pink due to the interaction of algae, archaeon, and environmental conditions, which influence the intensity and shade of the pink hue.
How many pink lakes are in Western Australia?
By our count, there are four extremely photogenic pink lake sites in WA to tick off the list, and one isn’t even on the mainland. These sites are famous for their bright pink hue, attracting guests and visitors hoping to catch the lakes at their most vibrant moments. Many guests explore these areas on foot, following a path to scenic viewpoints or nearby attractions like Lucky Bay. Under certain lighting conditions, the sky or reflections on the water can even appear purple, adding to the visual spectacle. Esperance’s Pink Lake, in particular, has a fascinating past and is a highlight for those visiting the region.
Hutt Lagoon
One of the most famous pink lakes in WA, this site is located right next to the coast, with the blue of the ocean bringing out the lake’s iconic bright pink hue. Plenty of films and series have been shot here, including international ones — and for good reason. So you’ve probably seen this particular pink lake on one screen or another!
Hutt Lagoon is located between Geraldton and Kalbarri, about five and a half hours from Perth. Given its soaring popularity, some pretty cool tours have popped up that you can book to really experience the lake. Guests on these tours often try to catch the lake at its most vibrant, especially when the sunlight creates a purple reflection on the water. And did we mention that these tours take place thousands of metres above the ground? That’s right, there’s no better view than the one from the sky. So hop on a plane, and get a bird’s eye view of this remarkable site. For those who prefer to explore on foot, there is a path along the shoreline offering unique perspectives of this incredible natural wonder.
Lake Hillier
This beautiful pink lake is located near Esperance, and by near, we mean a short boat ride away. That’s right, Lake Hillier is on an island — Middle Island, to be specific. While quite small, Lake Hillier is striking, with its bubblegum-pink hue set against white salt fringes and the deep blue waters of the surrounding Southern Ocean. The lake can be viewed from the air, with scenic flights departing from Esperance offering a truly breathtaking perspective.
For those visiting the island by boat and exploring on foot, local guides often share stories of Middle Island’s intriguing past. In the 1830s, it was reportedly home to Australia’s only known pirate — Black Jack Anderson — who is said to have operated along the south coast, using the island as a hideout. While there’s little visible trace of his camp today, the tale adds a sense of mystery and folklore to this remote spot.
Visitors should note that access to the lake itself is restricted to protect its delicate ecosystem, so swimming or walking near the water’s edge isn’t permitted. But the view alone makes it well worth the journey. And if you’re in the area, don’t miss Lucky Bay — nearby on the mainland and famous for its squeaky white sand and beach-loving kangaroos.
Quairading Pink Lake
Just under two hours from Perth, Quairading Pink Lake offers a fascinating twist on the typical pink lake experience. Unlike others that are entirely pink, this lake sometimes appears split in two — with one side a vivid pink and the other a deep blue. This rare contrast is thought to result from differing salinity levels between the two halves, influenced by seasonal water evaporation and rainfall.
The colours can shift dramatically depending on the time of year and light conditions, making it a favourite among photographers chasing something unique. On the right day, reflections on the water’s surface can even create a soft lilac or purple hue. It’s an easy day trip from the city — and a chance to witness nature’s palette at work.
Rottnest Island Pink Lake
Rottnest Island Pink Lake is a notable site, famous for its pink hue that captivates guests, especially at sunrise and sunset. While not as vibrant as others on this list, the lake’s color is a key attraction, and under certain lighting conditions, the sky or reflections can even appear purple, adding to its unique beauty. Unlike some other pink lakes, you can explore this site on foot, following a path that brings you right up to the water’s edge. Many guests try to catch the perfect photo of the lake’s changing appearance, aiming for that iconic shot that looks as if you’re walking on water.
What Makes WA’s Pink Lakes So Unique
There’s something surreal about stumbling across a lake the colour of fairy floss or rose quartz. Western Australia’s pink lakes don’t just impress — they mesmerise. Each has its own personality, with colours that can appear soft and pastel one moment, then vivid and saturated the next.
Lake Hillier is especially striking. Tucked away on Middle Island off the coast of Esperance, its bubblegum-pink water contrasts beautifully with the surrounding white salt crust and deep blue ocean — a spectacle best seen from above. Hutt Lagoon, closer to the Coral Coast, is equally photogenic. On clear mornings, its waters glow in vibrant pinks and corals, especially when the surface is calm enough to reflect the sky like a mirror.
No matter where you go, these lakes create a dreamlike experience that feels almost too perfect to be real, and they make for some of the most unique photographs you’ll ever take.
Planning Your Visit: Tips to Know
If you’re heading to WA’s pink lakes, a bit of planning can help you make the most of the experience — and ensure these natural wonders are protected for others to enjoy.
- Stay on marked paths: These environments are fragile. Walking on the salt crust or lake beds can cause damage and may be unsafe. Opt for designated paths or join guided tours where available.
- Choose the right time: The best lighting for photography is often in the morning or late afternoon, when the sunlight enhances the pink tones. Summer tends to bring the most vibrant colour.
- Check local conditions: Some lakes may appear more pink than others depending on rainfall, evaporation, and cloud cover. A quick check before heading out can help you time it right.
- Pack thoughtfully: Bring a wide-brimmed hat, water, and your camera — these are landscapes you’ll want to capture and remember.
By treading lightly and travelling responsibly, you’ll help preserve these delicate places for future visitors.
Protecting These Natural Wonders
The unique beauty of Western Australia’s pink lakes is matched by their ecological sensitivity. Over the years, some lakes have been affected by human activity and environmental change.
Esperance’s Pink Lake — officially known as Lake Spencer — once boasted a vivid pink hue but has since faded due to changes in water flow from nearby development and the closure of commercial salt harvesting. Restoration proposals have included reintroducing salt brine from the nearby Lake Warden system to increase salinity, though no project is currently underway. Experts remain hopeful that with the right conditions and support, the colour could one day return.
Lake Hillier, meanwhile, has remained consistently pink, but scientists continue to monitor it closely. Climate change, shifting rainfall patterns, and rising sea levels may all affect its delicate balance over time.
You can help protect these incredible landscapes by choosing eco-conscious tour operators, respecting local guidelines, and leaving no trace behind. With care, these lakes can continue to inspire awe for generations to come.
