Public transportation in Burgandy
I will be traveling witrh my wife to France in late September. We will spend a couple of days in Paris and then take the train to Auxerre. From there we have to travel to Baye, on the Naivernais canal, for a week's voyage north to Mailly-la-Ville.
It seems next to impossible to find transportation information, including costs, for travel within Burgandy. Specifically, where can I get bus schedules and prices for Auxerre to Baye, and for Mailly-la-Ville to Auxerre? I would prefer to travel by bus, but failing that, how much must I budget for for a taxi for each trip?
Any advice will be gratefully accepted.
