Located in Southern Mauritius , in the village of Chamarel , the Seven Colored Earth Geopark is home to a rough 7 - million - year - onetime , one - of - a - sort geological marvel . In keeping with Earth ’s taste for making thingsrainbow - colored , the guts dune of Seven Colored Earth are capably named due to their spectacular display of seven distinct colors .

There are a few rainbow - hued geological admiration around the reality , from China’sRainbow Mountainto theGrand Prismatic Springin Yellowstone National Park . It ’s also not the only place where you’re able to find colored guts . Namibia hasbizarre blue sandwhile Alaska is famous for itsjewel - like gumption . However , this is the only position known to have seven unlike types and colours of sand rubbing up next to each other .
One of the many fascinatingqualitiesof the colored sand found on the dunes is that if you take each different coloring and flux them together , eventually they will still separate and nail down into their own several mathematical group .
