hi
i've traveled last year through croacia...
i´ve began in klagenfurt - austria, pass slovenia, until dubrovnik - croacia.
It´s a amazing trip but every one that want to do it must be prepared for climbing. it´s sea side but with a lot of mountains
i can give some more detailed information, but i have only written in german and sloven, i´m workin in the portuguese and english versions.
let me know if it would help you.
you can se my work in progress in my webpage.... but it´s really incomplet until now.
i have only the first 7 days, from klagenfurt until ssibenik, but i intend to finish it really soon.
And only the german version is available
