Known as the birthplace of the Pilsner beer, Pilsen (Plzeň) is more than just a good beer. Just under 50 miles west of Prague, this Bohemian city has much to offer. The second-biggest city in Bohemia after Prague, Plzeň’s other attractions include a pretty town square and historic underground tunnels, while the Techmania Science Centre joins the zoo and puppet museum to make this a kid-friendly destination. The city is close enough to Prague to see the sights in a long day trip.
