If you are have an interest's in castles, I will recommend you do not miss the castle in Bojnice (Slovakia) - we have been impressed a lot. Close to the castle located thermal pools, so you can see a sightings and warm your body in hot water under the sky.
I wrote small report in Russian about our trip in 2010, you can see some photos about Slovakia
at least. If you will like I will let you know how to get it.
This year we are going to ride there again.
