Experience Christmas in Sopot. Although it’s probably too cold for swimming (except a quick drop after sauna) it’s still a great vacation time. Some hotels in Sopot like the Mera Spa Hotel have even special christmas offers like “Christmas with your family by the sea”. The town is much calmer then in summer but most of the restaurants and bars are still open. Except on christmas eve, where most restaurants close earlier.
A great idea is also to stay longer and also enjoy silvester in sopot. What could be a better place to start the new year then in Sopot in Poland?
