The tourist offices in Avignon and Villeneuve-lès-Avignon distribute free Discovery Passports . After paying the full admission price for the first museum you visit, you and your family receive discounts of 20-50 percent on the entrance fees of all subsequent museums in Avignon. The pass also gives you discounts on tourist transport (such as petits trains , riverboats and bus tours), and is valid for two weeks after its first use.
