Has anyone taken a train or bus from Cannes to Monaco?
I'll be doing so tomorrow. Trains leave almost every hour and the trip is about an hour. No reservation necessary.
Train it, it is easy.
Which part of Monaco do you want to go to on arrival? There are four exits from the station which go to different districts of the country.
If you take the bus it will take longer and is cheaper but not a lot cheaper. Because of the distance I believe you will be more comfortable.
Sit on the right facing forward. Then just look out the window!
