Thanks for sharing. It really should be on more peoples travel list. I went 15 years ago.. i went to the cave you show and the mountains too. It was just beautiful and I am so glad I went. I didnt realise but my grandpa was Slovenian! I was born in Australia to a german Dad who migrated after WW2. The family name was Omachen. It used to be Omahen but when they migrated bureaucracy changed the spelling. So when I was in Ljubljana someone said oh yes, its a common name here (in Australia it was very rare and no one.could pronounce or spell it). I rang Mum and she said yes, my Grandpa was from there! I dont know much about him as he died when I was young.
