Plzeň's most popular attraction is the tour of the Pilsner Urquell Brewery, in operation since 1842 and arguably home to the world's best beer. Entry is by guided tour only, with three tours in English available daily. Tour highlights include a trip to the old cellars (dress warmly) and a glass of unpasteurised nectar at the end.
Reservations are possible only for groups of 10 or more. Email the brewery to arrange.
