Take a tour of The Great Dune of Pilat in France – part of the World’s Greatest Attractions series by GeoBeats. This massive sandy expanse seems like it should be in the middle of a desert. But in fact, the Great Dune of Pilat is located on the west coast of France. This enormous sand hill is roughly 2 miles long and 300 ft. tall. It's one of the most popular recreational areas on the French coast. The Great Dune and its beach are a great spot to tan, picnic, swim, or play. Or, merely spend the afternoon on top of the dune and catch a beautiful seaside sunset. There are also shops, restaurants, and campgrounds near the beach.
