On my way from Cannes, via Paris I stopped in between flights from CDG to see the Tiara Château Hotel Mont Royal Chantilly. I couldn't believe, in my incessant hotel research something so beautiful could be so close to an airport. I spent a few hours at the property, touring and having lunch. Driving from the airport the scenery when entering the town of Chantilly to a picturesque sight, driving down roads and finally winding up at this beautiful Chateau.
