2. Lake Retba, Senegal

This beautiful pink stretch of water is found not too far from the Senegalese capital of Dakar, just north of the Cap Vert Peninsula. Lake Retba is also known as Lac Rose/Rose Lake, so that’s pretty obvious. The cause of pink water in nature is either due usually to a high content of certain salts and minerals or algae. In the case of Lake Retba it’s algae, namely Dunaliella Salina. The water also affects its surroundings with the samphire bushes growing in the terracotta dunes being magenta-colored. Like the Dead Sea, the salts create fantastic buoyancy if you fancy a float.
