Chamarel is a village on the south-western part of Mauritius that has a piece of land with 7 colours. This natural site composed of different shades ranging from tan to orange, to ocher. These shades, which attract the curiosity of thousands of people each year, are due to volcanic ashes that were made bare by erosion. The space occupied by the sand dunes is not very large, but this does not detract tourists from the dazzling spectacle offered by nature. Even if we try to mix seven colours together, these dunes mysteriously and automatically resume their original colour, just after a few hours. The scientific explanation of this place is still very vague. There was a time when Chamarel was a hotbed of witchcraft, but today it is a major tourist destination, which fascinates young and old alike.
