Lastours is about 12 miles north of Carcassonne, in the Montaigne Noir. This small town is famous for the group of four castles, towers really. The path up there is steep in places, but well maintained and safe. The views from the top are magnificent, especially when there is a dramatic sky. The view of the castles below is from a special ‘belvedere’ on the hill opposite. You have to pay an entrance fee to get to that viewpoint, unless you have paid the fee for climbing up the path to the castles.
