Fontainebleau and Vaux-le-Vicomte

The train that goes from Paris to Fontainebleau Avon (where you get a local bus to the chateau) goes through Melun where you can get a taxi from the station to Vaux le Vicomte. So you could go early to Fontainebleau and then take the same train back to Melun and head for Vaux le Vicomte.

Note that Vaux le Vicomte is closed most of the winter. I also would just pick one or the other than rush through each. Vaux le Vicomte during the spring summer and fall is spectacular and has a magnificent garden -- it is worth a day.

But if you are planning this now, Vaux le Vicomte is likely to be closed except for December Christmas events. The problem with those is getting back to Paris afterwards. I don't know when the last train is, but I would want to be sure to have my transport lined up before commiting to that. I can imagine going to Fontainebleau during the day and then to the evening program at Vaux.

Thank you so much! Have a great day

We are going to Vaux Le Vicomte 12/26 for the Christmas lights…. Thought about the train but now planning on car service… we are splitting the charge between 3 of us
