Great holiday in Slovenia

I have just returned from a great holiday in Slovenia. I was very impressed by the beautiful landscapes: mountains, waterfalls, lakes and hills. Ljubljana is a small but very attractive and friendly capital. The mediterranean was hot but beautiful. Piran was very pretty, yet rather busy. But most of all I was impressed by the original Karst: rills, gulleys, Dolines, huge sinkholes, natural bridges, a veeery large Polje and of course the caves. I was especially impressed by the huge canyon in the Skocjan cave.
