Did You Know {7} ~ Pink Lake Hillier, Australia

Fly over Western Australia for a rare visual treat: nestled among dense emerald-green woodlands surrounded by the deep blue of the Southern Ocean are a series of lakes in a shocking shade of bubblegum pink. One of the most well known is Lake Hillier, a 600m-long lake on the edge of Middle Island in the Recherche Archipelago off Western Australia’s south coast. Surrounded by a thin ring of sand and an expansive forest of paperbark and eucalyptus trees, the rosy pink lake punctuates a stunning landscape.

But even more surprising than its Pepto-Bismol shade is that “nobody seems to be able to definitively explain its distinctive colour,” according to Quora user Garrick Saito. Possible causes include the presence of green algae that can accumulate high levels of beta-carotene, a red-orange pigment; haloarchaea, a type of microorganism that appears reddish in large blooms; or a high concentration of pink brine prawn.

Most tourists admire the chromatic splendour of Lake Hillier from a helicopter or plane ride. For on-the-ground visitors, there’s an added treat: Lake Hillier is highly saline but the water isn’t toxic, so pack your swimsuit and go for a swim. Thanks to its high salinity, you’ll bob like a cork.

Did You Know {2} ~ The Black Sun, Norway

The Black Sun (Sort Sol in Danish) is one of the most magnificent natural phenomena in Denmark that’s worth seeing at least once. Thousands of visitors from all over the world travel to the Scandinavian country to watch the sunset being blocked by massive flocks of birds, as for a few minutes Denmark’s sky resembles a painting.

Every year in spring and autumn, up to one million starlings migrate from Norway, Sweden and Finland, and on their way to France, Britain, Belgium and the Netherlands they create one of the most unique natural phenomena in Denmark.

The Black Sun, or ‘Sort Sol’ as the Danes it call it, occurs in southwestern Jutland in Denmark during autumn from August until the end of October, and in spring from the middle of March to the middle of April – when the starlings returning to the north make a stop at Wadden Sea National Park’s marshlands to rest and find food.
