Bicycle tour along the Danube River

I am back--and added Austria to my list of international cycling spots. Our day trip to Durnstein & Wachau are known as two of the most scenic views along the Danube River. Sharon & I set out with a group and took an hour train ride from Vienna to begin our bicycling tour with winery stops! This person I found online explains the trail here. Along the way we had a chance to hike to the top of a ruin and take pictures! We could see the trail we had just biked. It was also nice seeing communities of bikers while we rode. I'd love to do the whole trail one day!
