Poland
Avoid traveling to Krakow and Warsaw in the summer if they are your main destinations because they are not always inexpensive. The spring months of March and April are the best times to visit urban Poland because the weather is warming up, the cost of living is still affordable, and the castles and palaces that were closed for the winter are now reopening, often at discounted prices.
You won't waste time standing in line because Poland's most well-known attractions, such as the Auschwitz-Birkenau camps, the Wieliczka Salt Mine, and Schindler's factory, are significantly less crowded in the off-season. The Old Town Hall tower in Krakow, the 13th-century Castle of the Teutonic Order in Malbork, and the historic Bialowieza Forest are some of the places to see in the nation that are cheap or free. The Royal Castle in Warsaw is free to enter on Wednesdays, while the Chopin Museum is free on Sundays. This is a common practice among museums in larger cities. Although trains in Poland aren't usually particularly affordable, buses can take you practically any place for very little money. You can travel to even the smallest towns in Poland on comfortable, free Wi-Fi-equipped long-distance buses like those from Flixbus.
