Two weeks ago I was able to spend a day in Paris thanks to the super speedy Eurostar. You can jump on the Eurostar from Kent or London and it will get you to Paris in just 2 hours. I've done this before and if you book the tickets in advance you can get them for £69 return.
When in Paris we decided to hire a moped for the day to get around as this is a much quicker way of seeing the city especially when you only have 12 hours. Then of course we saw all the tourist spots, ate crepes and even had a little sunbathe (sleep!) under the Eiffel Tower.
The sun was shining and it was such a perfect day. I hope you enjoy the photos :)
