After a few days in Salzburg, I'm planning on a few days in Ljubjlana. It appears to be only a 3.5 hour drive between the two, but I wouldn't mind spending a night or two at a scenic lake. We are hikers so a pretty town with nice trails and good beer for dinner will be fine. We will have a rental car, and will be starting in Munich, and probably driving back there again after our time in Slovenia. This will be the first 2 weeks of September.
I think I've decided not to go to Hallstatt, too touristy.
Suggestions appreciated, thanks.
