Crowning the village of Les Baux, these dramatic, maze-like ruins date from the 10th century. The clifftop castle was largely destroyed in 1633, during the reign of Louis XIII, and is a thrilling place to explore – particularly for rambunctious kids. Climb crumbling towers for incredible views, descend into disused dungeons and flex your knightly prowess with giant medieval weapons dotting the open-air site. Medieval-themed entertainment and hands-on action – shows, duels, catapult demonstrations and so on – abound in summer.
Joint tickets are available with the Carrières de Lumières (adult/child €18/16 in summer).
