Discover the stunning pink Lake Hillier in Western Australia. Learn why it’s pink, how to visit, and everything you need to know about this natural wonder.
Lake Hillier, Australia is one of the most stunning pink lakes on Earth.
Imagine flying over a tiny island in Western Australia and spotting a bright pink lake surrounded by deep blue ocean. Sounds unreal, right? That’s Lake Hillier, one of the most eye-catching natural wonders on Earth. With its bubblegum-pink color and stunning contrast against the greenery and sea, Lake Hillier is a must-see — especially for curious travelers and nature lovers.
Let’s dive into the mystery, science, and how to visit this magical lake.
Where is Lake Hillier Located?
- Island: Middle Island, the largest of the Recherche Archipelago
- Region: Goldfields-Esperance, Western Australia
- Nearest Town: Esperance (off the south coast)
- Accessible only by air or boat
Why is Lake Hillier Pink?
The exact reason for the bright pink color is still a bit of a mystery — but scientists believe it’s due to:
- Dunaliella salina – a type of salt-loving microalgae that produces a pink/red pigment called beta-carotene
- Halobacteria – microorganisms that also contribute to the color
- High salt concentration + natural chemical reactions = the vibrant pink
Fun Fact:
Even if you take the water in a bottle — it stays pink!
Is It Safe?
Yes — Lake Hillier is not toxic. It’s just too salty for swimming (almost as salty as the Dead Sea). However, swimming is not allowed to protect the environment.
