Prague, Czech Republic

With its historic center coated in snow, Prague is a stunning winter destination. Prague is known as "the City of a Hundred Spires" because of its Gothic churches and the medieval Astronomical Clock. Walking across the Charles Bridge, which is blanketed in snow and flanked with sculptures of Catholic saints, is one of the nicest things to do on Valentine's Day.

Prague was originally a secret jewel, overshadowed by its flashier western neighbors. But the city couldn't keep its wonders hidden for long, and it's now a haven for travelers looking for awe-inspiring experiences at reasonable prices. Even today, key attractions such as the famed Charles Bridge and the ancient Prague Castle are free to enter, and many hotels provide rooms at a fraction of the price of other European cities.
