For Film buffs there are two highly regarded international festivals to choose from each summer, one at Motovun (July and August) www.motovunfilmfestival.com and one at Pula (July) www.pulafilmfestival.hr.
The hill-top village of Groznjan has classical music concerts throughout the summer, as does Rovinj and there are concerts every Friday throughout the year at the Euphrasius Basilica in Porec. For a unique sporting experience, how about a round of golf at the restored 18-hole course on the Brijuni islands? Originally built in 1922, this has to be one of the most spectacular settings for a golf course in the Mediterranean. http://www.brijuni.hr/en/Home.aspx?PageID=47
