What are some of the heapest countries in Europe (east and west) to travel to that are still exciting?

Answer 1

All countries in Europe are exciting, if you do what you like.
You can go for outdoor sporting, like rafting or long hikes, or for city visits and see history or nightlife, or for views and see mountains, flat country, a beach holiday and so on.

So select a few countries for which you have a good reason, like family roots, because you have always wanted to go there, because the sport options attract you, or select purely because of prices.
And you can have as much fun as you want.
