August 2024 - After visiting family near Cracow, we drove through Slovakia next day without omitting Kezmarok, Levoca, Spissky Hrad and Slovensky Raj. 
We arrived at the campground at Baradla in the evening and had a clear sky to see probably all stars of the northern hemisphere. 
Next morning, my birthday, we signed up for a tour to Baradla Cave. Really fascinting stalagnites and a nice 1,5h tour which our kids enjoyed as well. It is probably one of the easy accessable, yet fulfilling experiences. 
From there we continued to Tokay.

August 2016 I had visited Dobcinska Ice Cave after a day hike in Slovensky Raj.
