Patti and I will be cycling the Danube Bike Path at the beginning of September. We have a flight into Zurich and will most likely start cycling from there to Donaueschingen, rather than taking the train. Can anyone suggest any routes? We are aware that we are going to be climbing for long stretches and that it will possibly be one of the tougher stretches of our entire trip, which ends at the Black Sea in Romania. What kinds of grades can we expect on that stretch? and how long are some of the climbs? Is traffic generally a problem? are there amenities along the way?
Any information would be greatly appreciated.
