EuroVelo weaves about either side of the what was the Iron Curtain. There is great variety. The route mostly keeps away from major through routes but after the big hydro dam that is a border crossing point into Romania there is a 10k horror section with heavy trucks inches away... Mostly though, its very well done and ideal for an 'adventure bike', with a nice mix of surfaces and very little traffic. Scenery is frequently stunning. The Danube section is popular with anglers. The Romanian side is a disgrace of junk left by angler campers.
