Christmas Day and Christmas Eve is the most important day of the Christmas Holidays for all Czechs. It's a day that most Czechs spend at home with their families. With less crowds especially in the afternoon, this is a wonderfully peaceful day to explore Prague. Especially as the squares are often dusted with snow or a heavy frost, giving the city a real 'olden day' charm.
For visitors, there is still sightseeing and plenty of activities and entertainment on offer. But hours are limited and only a small number of shops, bars and restaurants are open, so it takes a little planning.
Christmas markets (Vanocni trh) are a key ingredient of the festive magic in the Czech Republic, and the Prague Christmas markets are among the most impressive. The markets light up the city, bringing locals and tourists together in a true 'winter wonderland' setting.
In the company of your personal guide, walk around the brightly decorated wooden huts selling traditional handicrafts of the market. There is a variety of Christmas trees and locally crafted ornaments, candles, and ceramics. Buy some gifts or souvenirs to take home. Your guide will point you in the direction of the best spots to purchase what you're looking for. Taste some traditional foods as "cukroví" (christmas cookies, they come in a hundred different forms and recipies :-)) and, of course, mulled / hot wine.
