Danube Bike Tour from Passau to Vienna: We did the tour along the Danube in May 2014. Everything was perfect from the moment that we first got in touch with RFH. Mel took care of every detail and we didn´t have to worry about a thing. The hotels (Category B) were all lovely. The breakfasts were great and the dinners on half board were surprisingly good. The hire bikes were excellent quality, if a little heavy for someone (like me 🙂 used to a lightweight road bike. The route is lovely. We had perfect weather and enjoyed every day. There is no danger of getting lost, even if you do head off to visit some of the sites that are away from the river. Next up: The Salzburg lakes!
