On our drive from Bohinj to Piran? Is that a lot out of the way? Thanks
Check ViaMichelin.com for driving-time estimates (probably somewhat optimistic).
Not at all, it is close to the exit of the highway in Divaca.
Do we need reservations?
No, just show up twenty minutes or so before the tour to buy the tickets. The tours run every hour from 10am to 5pm in the summer months.
