Sign up for a one-hour guided visit at the Maison des Mégalithes, which explores the history of the site and has a rooftop viewpoint overlooking the alignements. Tour times vary considerably depending on the time of year but they run twice a day (in French) during the summer. English tours are available at least once or twice a week in July and August – call the Maison des Mégalithes to confirm times.
