I have a question about one of the bus journeys on the Best of the Adriatic tour. The itinerary says that on day three the tour will have "a scenically winding, mountain-pass drive to the breathtaking Soča River Valley." I assume the "scenically winding mountain-pass" is the Vrsic Pass. I base that on a Cameron Hewitt blog post in 2016 in which he said that the best scenery in Slovenia is deep in the Julian Alps and the best route for seeing it is the one-day drive over the Vršič Pass, then back down along the Soča River Valley. He said the Rick Steves Best of the Adriatic Tour was designed to include a day for this journey. The photos on that blog post are stunning.
Somewhere, I'm almost positive I read that the Vrsic Pass is a summer only experience, that it is closed after summer. But now I can't find that again. If we take the Best of the Adriatic tour in late September or early October, will something else be substituted for the Vrsic Pass & Soca River Valley drive? Or is it possible that drive will still be done, but it's weather dependent, no one can know in advance?
