When is the best month to travel to Europe?

I think the best tourist month in Europe is summer (June to August). The weather is warm and suitable for outdoor activities. However, there are more tourists, the scenic spots are crowded, and the prices of air tickets and accommodation are rising. If you like to avoid the peak season, spring or autumn is better, the weather is pleasant and there are fewer tourists. Some countries have special activities in certain seasons, such as Oktoberfest in Germany and Venice Carnival.
