I only managed to reach four of the listed caves, three in Slovakia and one in Hungary.

Dobsinska Ice Cave : similar to the Dachstein ice cave in Austria, but easier of access. Entry E6. Access by bus from Poprad-Tatry station.

Jasovska cave : featured splendid caramel coloured rock formations. Entry E5. Access by bus from Kosice.

Ochtinska cave : featured spaghetti-like stalactites. Entry E5. Access by bus from Kosice or Roznava, then 2km walk.

Kossuth Cave : found the entry, but was closed. Access by bus from Aggtelek-Josvafa station.
