Lake Retba is situated in Northwest Africa, in Cap-Vert Peninsula Senegal and lies 30 km northeast of the capital, Dakar. This lake is famous because of its unusual yet vivid naturally occurring pink color. The color of the lake is caused by the Dunaliella salina bacteria, which is attracted by the lake’s salt content.
This color is especially visible during the dry season which starts in November and ends in June. It is not the only pink lake in the world. It is also known as Lac Rose by the locals.
