Last year we visited Paris and used the trains for the first time. We are very familiar with train travel in the UK, but were initially hesitant about doing the same sort of travel in France. Having now discovered that France train travel in general is a non issue, we are planning another trip.
What we have in mind is flying into Paris and at some point taking the train to Nice, from where we would fly out.. As this is something like a 5 1/2 hour train trip we thought we might break up the trip into several segments by stopping overnight at various small towns along the way.
Which brings me to the actual question, does anyone have suggestions for what stops, along the main train routes might be interesting ? Our major interest is photography, which means old quaint villages, ruins, cathedrals, castles, that sort of thing. Not big on museums, reenacted jousting tournaments, or that sort of production. We customarily walk long quite a bit during our sightseeing so that is not a problem.
