One base worth knowing about if you're counting on public transport in the area is the pretty but otherwise unexciting hillside town of MONTBARD, which is on the main railway between Dijon and Sens and where buses leave for both Chatillon and Semur. It has well-priced accommodation options, including La Sirène, on avenue Leclerc (Tel:03.80.92.07.21; Price: Under 50), with simple rooms above a bar in a nice spot by the canal.
