Here’s a short Instagram video from a weekend trip to Oberwiesenthal in January. What more is there to say?
Located in Krkonoše Mountains, it’s similar to Klínovec / Fichtelberg, but reachable only by car, 4+ hr drive. The local food and its abundance are worth special notice.
Probably the nearest skiing place to Berlin; one-day bus trip from 69eur including ski pass (also includes a luxurious wake-up at 4am).
