A well marked trail! Mostly on paved bike paths or sidewalks, through small villages, around a port with big ships. About 10 miles and it was hot and humid. Going to the mountains might have been a better idea after all. But the paths through olive groves and past gardens make it pleasant.
There was no border crossing and Slovenia is on the Euro, so that is easy.
Containers arrive on ships from Asia with cars. Looks like the cars are wrapped for the trip.
