Lake Retba is pink because of its high mineral content that generates a chemical reaction with the high salt content and because it has so much salt, everything on the water floats. It’s a great place to teach people to swim because you will not sink. Retba can change to a violet or mauve color after the sun goes down. Surprisingly just a few yards from the salty lake is pure fresh water where fish and frogs happily swim around in the fresh water – not affected at all by the salty lake nearby.
There are 8 Pink Lakes in the world!
