The Centre mentioned is not worth it but Dijon is worth a couple of days. There are lots of OK hotels just out the train station for around 40 euros a night. Visit the Mustard Museum. The Visitor Centre is fairly helpful and just out of the train station -- they rent mountain bikes there.
Dijon is the historical and commercial capital of Burgundy. It is home to many historical buildings from the time of Guillaume the Conqueror who ruled a region more than 5 times the size of present-day Burgundy. Some of these historical places have been converted into museums which are interesting to visit.
When you stay in a Dijon hostel we recommend immersing oneself in the center of the city and taking a walk on the cobbled streets, browsing the souvenir shops and sampling the specialty foods (mustards, ‘pain d’epice’ (a kind of gingerbread), Dijon ham, berry liquors and more). This can be a nice and cheap way of spending a day in Dijon.
The famous burgundy wineries are only a small train hop away (it is not recommended to drink and drive), as is the city of Beaune. Dijon has also an artificial lake with well-maintained trails used by the locals for walking and running. In early September, Dijon hosts a festival called: ‘Les Fetes de la Vigne’, during which many dancing groups come from all over the world to perform.
There are limited choices for hostels in Dijon (as seems to be the case in most of French cities). Dijon hostels tend to be situated in the suburbs of the city, or near the University. You can reach the main attractions from your Dijon hostel by public transportation. Although if you have your own means of transportation, you can visit the countryside and, in the autumn, enjoy the celebrated golden colours of the leaves.
