Your first stop when visiting Bernkastel Kues should most definitely be the tourist information center. They have a ton of info about these two little towns and it is all free. Once you walk across the bridge you will see this gorgeous building to your left, so it's not even out of the way. The staff was very friendly and the woman who helped us spoke great English,which was appreciated even though I know I should speak German! She told us a a few tips, informed us about the wine train which we chose to pass on, and gave us a great intro to the area. It's easy and free, so why not stoping?!
