When the lake in front of the extravagant Vajdahunyad Castle freezes over, this is the biggest skating rink in Europe. This area between Hero's Square and the castle is an extraordinary setting. And Hungarians make the most of it: as a spectacle of massed entertainment, it's hard to beat. Tragically, the lake rink is closed this year for reconstruction, but instead you could head to the new rink on top of West End City Centre: the biggest shopping mall in Central Europe!
