We drove a rental car south from Warsaw...stopping in Sandomierz, of course. Don't miss that town either...it's great. The roads are good although only two lane. Traffic moves along pretty well and there aren't many cars on the road. We came upon construction in a few areas which slowed us slightly, but when on vacation, you really shouldn't fret about little delays. Gives you a chance to look for storks in the fields or mistletoe in the trees!
Branów Sandomierski is a small town 7 km SW off the maine Route 9 [E371]. You can get there on the secondary road 985. Really, driving will be the fastest way to get there. Just to give you an idea of where it is located:
- about 230 km south of Warsaw, and 135 km NW of Krakow
- the closest major town is Tarnobrzeg, 9 km to the NE
If you want to use public transport, it'll be a bus. If you can't find a direct one, choose any that goes to Tarnobrzeg, and then take a bus from there.
