They look as though someone has tipped in a load of pink dye while no one was looking. But in fact these pink lakes are a natural phenomenon.
From the vibrant Lake Hillier, Lake Retba and Torrevieja, these shots show how algae can look so beautiful.
Lake Hillier on Middle Island is a small pink-coloured lake.
Lake Retba, in the Cap Vert peninsula of Senegal, has a high concentration of salt which is harvested by local people.
Some of the most urban of the world’s pink lakes are found next to the Spanish city of Torrevieja, in South West Spain.

Awesome pink lake phenomenon
