The Slovenian leg of our trip will be over around May 21-22, and we will be heading to Italy. I've looked through my Lonely Planet Slovenia, and this is my understanding of how to get to Italy. There is a small chance we will stay in Trieste, but most likely we will push through to Bologna.
If we're leaving from Ljunljana, we can take a bus or train to Trieste and then transfer to an Italian train. If we're coming from the coast (iran, Izola or Koper) then we take a bus to Trieste. Apparently the ferries won't be running yet.
Are there any other options (not interested in driving or flying)? Is there anything else I need to be aware of? Thanks!
