The Seven Colored Earths in Chamarel is one of the most unique natural wonders of Mauritius. It features small dunes of sand in seven distinct colors—red, brown, violet, blue, green, yellow, and purple—formed naturally due to volcanic activity. What’s fascinating is that even when the sands are mixed, they separate back into layers of color. The site is surrounded by lush greenery and also includes a waterfall, a giant tortoise park, and scenic viewpoints, making it a must-visit spot.
