More than 300 kilometres off the coast of Nova Scotia lies one of Canada's most extraordinary natural landscapes.

Sable Island, a narrow crescent of shifting sand in the Atlantic Ocean, is unlike any other place in North America.

Despite its harsh weather, moving sand dunes and complete isolation, the island is home to a thriving population of wild horses that have lived without human management for generations.

There are no permanent residents, no roads and very few visitors each year.

Protected as a national park reserve, Sable Island has become a haven for wildlife and a living laboratory where scientists study everything from coastal erosion to animal behaviour in one of the world's most unique island ecosystems.Where is Sable Island and what makes it one of Canada's most unusual islands?Sable Island is located approximately 300 kilometres southeast of Nova Scotia, Canada, in the Atlantic Ocean.
