Château de Chailly is a good starting point for a bike ride as there are many pretty little hamlets and small rural villages in the area. The setting is very picturesque and the small roads are ideal as there is not much traffic. We can suggest some routes given the length of your desired bike ride.
For a more leisurely bike ride, we recommend riding on the Burgundy canal (either starting from Pouilly-en-Auxois, which is about 20 minute bike ride from Château de Chailly, or starting from Vandenesse-en-Auxois, which is about a 45 minute bike ride from Château de Chailly).
We rent bicycles for 10€ per day at Hôtel Golf Château de Chailly.
For visitors who are more interested in a organized bike tour, we recommend Escapade Gourmandes
