This is a must see if you are anywhere near Carnac. There are a number of fields containing the upright stones scattered about the area. There is a visitors center adjacent to several fields and this is a good place to get oriented and start exploring. There is a small tourist "train" that will take you around the area but we found this to be not worth the price. You can achieve the same thing with a car, a map, and a brochure. If the menhirs (stones) fascinate you, be sure to visit the Locmariaquer site (nice although small museum with a very informative film in either English or French) and the Prehistoric Museum in the center of the town of Carnac.
