The Patras tourist office (EOT) can provide information about local festivals and events linked to the EU's designation of Patras as the 2006 Cultural Capital of Europe.
For nightlife in Patras, in general it's best to ask around when you arrive, as the scene changes. On the northern side of Platia Martiou 25 are the steps at the head of Gerokostopoulou street, below the odeon. Closed to traffic along its upper reaches, this street has myriad cafés and music bars, making it a good choice for a relaxing evening. It is the place to be for the young and hip of Patras.
