The most celebrated merrymaking in festive Mainz is the All Fools capers at Carnival each spring, on the Monday and Tuesday before Ash Wednesday, where merrymakers act like fools, jesters, and clowns. This festival is broadcast throughout Germany the way the Macy's parade is throughout the U.S. There's also an annual Wine Fair the first week in August and the first week in September. For information, contact the tourist office at tel. 06131/286210.
Trams and buses fan out across the city from the Hauptbahnhof from 5am until around midnight. Fares start at 2.50€ and vary depending on how far you go.
