It covers things like entry to the Louvre, Musee de Orsay and Georges Pomidou Center and no lines people!! Others included Arc de Triomphe and Notre Dame amongst many more. After all the museums and monumnets I visited whilst in Paris it more than paid for itself and the convenience was really wonderful... just flash the pass and you are through.
