1. Lake Hillier, Australia
A lake in a shade of millennial pink? There might not be a natural landmark quite so fitting for sharing on Gen Y’s favourite app. Situated on the edge of Middle Island in Western Australia, the saline lake’s bubblegum hue is not fully understood by scientists, although it’s suspected to be related to the presence of microalgae. While this isn’t the only pink lake in the world, it’s arguably the most vivid. A snap requires some effort as you’ll need to experience the landmark from above (since normal tourists can’t physically visit the lake), taking a helicopter service to Middle Island from the town of Esperance. Handily, Esperance is a visual treat in its own right too – thanks to piercingly blue-watered beaches and offshore sightings of dolphins, fur seals and sea lions.
