The Pink Salt Lake of Torrevieja, Spain

The Pink Salt Lake of Torreviega (Salinas de Torrevieja) is a sight to behold. Looking like a strawberry milkshake, the colour is the result of algae and bacteria that thrive in salty water. The water is perfectly safe and it can be fun to float around in the pink water. Keep a camera handy, as flamingos are known to visit the pink lake to enjoy the shrimp that lives there. Atlas Obscura writes that their food is the cause of their pink colouring.
