Only available on-line at www.paris-pass.com, the Paris Pass is essentially a repackaging of the Paris museum pass and a Paris Visite travel pass.
But the Paris Pass does include entrance to some attractions that are not included in the museum pass such as the
Paris Opera House,
a one hour boat trip with Bateaux Parisien,
Musee Grevin, and the
A free wine tasting is also offered.
The Paris Pass also offers discounts at many shops and restaurants, contact the website for specific details.
The claims made on-line about bypassing the long ticket queues with a Paris Pass are also true of the museum pass.
However buying a museum pass and either a carnet, (book of public transport tickets), or a Passe Navigo Decouverte (travel pass) is considerably cheaper than purchasing the Paris Pass.
A two day Paris Pass costs 89 euros, and a two day museum pass costs 32 euros, add a carnet with ten trips for 11 euros and you can see that you could be paying 46 euros more.
Research what you wish to do and calculate the costs to see if the Paris Pass is of value to you.
Remember, Paris Pass is run by a company that offers passes in many cities, for a premium!
