Crossing the tail of the serpentine lake, follow the path that leads along the embankment until you hit the Amphitheatre, also known as the Theatre on the Island. Built to resemble the amphitheatre at Herculaneum, the theatre hosts productions throughout the summer, though unless you fancy seeing Henry V in Polish these will hold little interest for foreign visitors. (There are exceptions: ballet and contemporary dance sometimes get put on here). It is enough just to admire the setting before heading for one of the kitsch (one features an enormous swan) but irresistible gondolas that ferry up and down the lake during the warmer days beginning in April (weather permitting). A short trip costs 8/6zł per person, and trips depart throughout the day - you may have to wait for the boat to fill up before the gondolier sets off however.
