Once a royal hunting estate, the 63-sq-km Forêt de Chantilly is criss-crossed by walking and riding trails. Long-distance trails here include the GR11 , which links the Château de Chantilly with the town of Senlis ; the GR1 , from Luzarches (famed for its cathedral, parts of which date from the 12th century) to Ermenonville; and the GR12 , which heads northeast from four lakes known as the Étangs de Commelles to the Forêt d’Halatte.
The tourist office stocks maps and guides.
