The large Slavs and Vikings festival in Wolin (usually August, several days) – right nearby if you're in the area. Address for the festival office: ul. Recław 37, 72-510 Wolin (info on jomsborg-vineta). Three days of shows and lots of hustle – great for history fans, less so if you're looking for absolute peace. Check online beforehand to see what's planned.
