Although I've visited France on a number of occasions, and even passed through Paris while catching sleeper trains to other parts of Europe, I'd never actually stopped to see the city.
That changed (a bit) on the return leg of my Round the World III trip. I'd flown from Lima into Madrid, and caught the sleeper train from Madrid to Paris. I arrived early in the morning, and had a Eurostar ticket for departure in the afternoon.
So I dumped my bag in the left luggage in Gare du Nord, and headed out on the Metro. First stop was to Notre Dame de Paris, which was packed with tourists. I got a few good photo's and then walked down the River Seine, the bad news is that the weather is very overcast, and when I see the Eiffel Tower it's top is hidden in the low cloud.
I stop off and buy a real French croissant for breakfast - and it's very, very good! After a look at the tower (by the time I got up close the cloud had burned off) I headed up to Montmartre for some great views over the city, and had a look around Sacre Coeur. All to soon it was time to head back to the Eurostar terminal and get on the train to London.
