Party with the Locals in Viareggio: This crowning event of the six-day festival has an intoxicating, joyful flair. Begins on January 27th and ends on February 17th.
Carnaval di Viareggio: Its main characteristic is given by the parade of floats and masks, usually made of paper-pulp, depicting caricatures of popular people, such as politicians, showmen and sportsmen; the parade is held on the Viareggio avenue located alongside the local beach.
Beaches: The coast is lined with sandy beaches, most part of privately owned facilities although there is a free beach area in the south part of the city. Most facilities have a snack bar too. The sea is usually calm and good for swimming.
Promenade: A long seafront promenade lined with shops, cafes, and restaurants runs between the beach and town. The south end has Liberty-style architecture.
Pineta di Ponente: The large pinewood park, just two blocks from the beach, is a good place for walking and escaping the sun.
