You must take this tour. It's up in the mountains and it gives you a different perspective. The guide was excellent. Unfortunately, the weather did not let us appreciate the views of the mountain.
The pass was awesome. It allowes you to save money. It is really easy to pick up the pass at the hard rock. It comes with tickets for the metro, a museum pass, and the paris pass card and the book is really helpfull. it tells you how to get to an attraction by metro and gives the closes metro exit.
