The nearest Christmas Market is always held in Wrocław (capital of Lower Silesia- 1,5 h drive). It is beautifully spread all over the main market square. In the small wooden houses you can find anything you can think of! Mulled wine, spirits, juices, sausages, smoked hams, cheeses, homemade bread, rolls and pastries, gingerbread, cookies, ornaments, scarves, hats and gloves and so much More. And the atmosphere is just amazing! Starts late Nov and goes on till end of Dec. Krakow, Poznań, Warsaw and Gdansk have their own Christmas markets too.
Speaking of Christmas ornaments- have you heard of VITBIS, the world famous producer of Polish glass ornaments? It is only 30 min drive from Bolesławiec in Złotoryja! You can buy the goods at very affordable prices (from 1 USD !) and also visit the factory and even make your own ornament! Do not miss the opportunity. I can obviously organize a tour to that place too.
