Forêt de Chantilly
Forêt de Chantilly information
Lonely Planet review
South of the château is the 63-sq-km Forêt de Chantilly, once a royal hunting estate and now criss-crossed by a variety of walking and riding trails. Long-distance trails here include the GR11 , which links the château with the town of Senlis and its wonderful cathedral; the GR1 , which goes 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.
