Apart from the trail in Slovakia, these are secluded places, not contaminated with the tourist plague. You won't see too many tourists there, and there aren't many guided tours available. Unless, of course, they are not aimed at exploring places off the trail in Slovakia. Contrary to appearances, although Slovakia is highly appreciated by tourists, you can easily find places there that are not heavily crowded by them. You will definitely visit Žilina and Banska Bystrica . Both are treated by most people as a passing point during a longer route. However, both cities have a nice old town, perfect for a walk. You can also count on an intimate atmosphere in Nitra , where you will find an impressive castle.
