Lake Hillier is a bubble-gum-pink lake right on the edge of Recherché Archipelago’s largest island in Australia. It’s literally just a few steps away from a “normal” coloured Southern Ocean, but despite the pressure from its neighbour it refuses to compromise its pink colour. Scientists cannot figure out why Lake Hillier is pink, speculating that it’s caused by a reaction of sea salt and sodium bicarbonate (which you know as baking soda), or caused by red halophilic bacteria in the salt crusts. But, it is equally likely that there is a giant underwater strawberry farm.
Farm or not, you’re probably just wondering whether or not you can swim in Lake Hillier. Well, good news: as any Aussie will attest, it’s really just a salt lake; really salty, but perfectly safe to swim in. At the same time, being Australian toughens one up to swim in just about anything, including molten lava. We were also unable to find any photographs of Aussies swimming in Lake Hillier, but that could be just because they are too tough to swim in a pink lake in the first place. Presumably their only use for this pink lake is to bottle and export it as treatment for non-Australian problems like upset stomachs, nausea, heartburn, diarrhea, and indigestion.
