Another peculiar little country is Monaco which looks like the the French Provence surrounding it. Marvellous sea views from the famous road along the Mediterranean Sea, Corniche. Monte Carlo is mostly Casino and expensive yachts in the harbour. We had ice cream and watched staff taking care of these massive boats before continuing our way on the Corniche (or back to Cannes… not sure)
When we went by car to Barcelona from Hamburg in 1996, I saw the opportunity to make my parents go to Andorra. It was interesting – a real city which surprised my teenage self out of some reason. Very mountainous and with a ski area. And woops, we had left this little country again.
