In the northeast corner of Saskatchewan, the Athabasca Sand Dunes Provincial Park includes the world’s most northerly set of dune fields and Canada's largest active sand surface. The dune fields stretch for 60 miles along the shore of Lake Athabasca, with dunes reaching almost 100 feet high. Shifting at a rate of about 5 feet per year, the dunes create a literally moving landscape. The fragile environment supports rare plants from dune grasses to pitcher plants and shows evidence of Aboriginal use dating back more than 7,000 years. It is also home to a number of animal species, and near the lakes in the area you may see black bears, moose, and red squirrels. A number of rustic campgrounds in the area are available on a first-come basis.
