The problem as I can see, and not only in this thread, is that many people living outside Europe have a skewed and restricted picture of Europe. In topics on WE branch at least 90% of visitors ask the same typical questions about the same typical places like London, Amsterdam, Barcelona, Venice, etc. Only in recent 10 years they've added Prague and Krakow plus a few others.
With a few rare exceptions, even in this thread, countries that are discussed are France, Spain, Italy, the Netherlands. Someone has mentioned here Modlova and Albania. That is still today cosidered very adventureous by most Americans or Canadians.
Europe is about 50 countries. Those 90% of typical travellers think and talk about 6 or 10 of them. I've travelled for 35-40 years and still haven't managed to see them all, and I know there's so much left to discover.
Has anyone here considered visitng Caucasus, the other end of Europe?
Two weeks ago I returned from a trip to Georgia.One of the oldest civilisations in Europe, a country that became Christian in 4th century (2nd in Europe). There're historical monuments from 6th, 8th 12th century. There're places that are mentioned in Greek mythology (Kolkhida/Colchis - the destination of Argonauts and place of Amazons). The legend of Saint George has spread from Georgia to most of Europe, including England where St George became saint patron of the country.
Georgia was probably the first country to produce wine, 3-4000 years ago. Food is very good, culinary traditions are very old and rich (read about supra). Georgians are extremely friendly and hospitable people. The landscape is beautiful and varied, the highest mountrains of Europe with green valleys and rivers, and the vast coast of Black Sea.
The country is still very cheap, very safe and easy to travel. Europe, at least in that part, is not over yet and far from it. Actually, there're hardly any westerners there, which for a visitor like me is quite nice. I too, like OP, don't like to travel with big crowds.
