We will be traveling to Slovenia in late September, and renting a car from our first stop, which is Bled (after taking the train from Munich to Lesce-Bled). After hiking in the Bled/Triglav National Park area for a few days, we'd like to drive to the Goriska Brda region. Ideally, we'd like to stop at Kobarid along the way to Goriska Brda because that area sounds fascinating too. After a few days in Goriska Brda, we'd like to drive to Piran for a couple days. After Piran, we'd like to drive to Ljubljana for the remainder of our trip.
Does this sound like a doable driving route? Are the roads decent? We are from the US midwest and not accustomed to serious mountain driving. We're a party of six adults and will have two cars. Do you have any tips for this route, or suggestions for modifying it? We have hotel reservations at each stop, but I believe we can modify them as needed. Your input is very much appreciated!
