My first trip to France took me from Mont St.Michel in the north down to Marseille in the south.
The trip included a visit to amphitheater in Arles.
As a technical site-note: Since Calais was on the way, it was easy to do a short detour to the hovercraft landing site. Back then, there weren't any fences or barriers, so you could walk across the dunes right up to where the hovercrafts came in. I was duly impressed by watching it come in, but it took me about 17 years before I actually got around to using one. See here. [Btw, the boy in the lower left of the picture is not me, just some random spectator. I was quite a bit older than that in 1983.]
