Having just come off 2 weeks biking in France we had something to compare this trip with.
The first 3 days or so were magic - lovely views, fantastic track surface and finally cool weather. The accommodation was great,especially after we were upgraded twice, and can be recommended.
The bike gear was top class but my bike however was not. Euro Velo bike hires have to realise that the standard puffy commuter seat they supply are not comfortable for guys used to proper bike seats - enough said. Also on the second day when I went to use the smallest front chain ring it turned out that 2 of the mounting bolts were missing and it got wrecked so one third of my gears were gone. Managed to get this repaired after a couple of days but wasn't really satisfactory. This should not happen!
The directions and maps hardly ever match up completely on these type of trips but we were certainly not happy to discover at the end of a long hot day that the instructions for the approach to Salzberg were in fact for someone coming from completely the opposite direction - a victim of cut and past to be sure, as was the odd paragraph still in Austrian, but this should have been edited properly. A shame as the general standard of the material presentation was of a high quality.
Be aware if you want to do this trip that the last few days are along the stop bank beside the river and are boring - very little in the way of scenery and culture. Next time we will detour inland.
Sorry but overall a 3 star effort.
Warning - in case you may be considering a taxi ride from Innsbruck to Krimml to start your trip make sure that the driver is legitimate. Ours was a temporary fill in, had not driven out of town for 4 years and was a thoroughly unsafe driver. Much too fast and I suspect maybe on something. He almost ran off the road a number of times and clipped the inside kerb a couple of times . Haven't been so scared in our lives as passengers apart from jeep trips in Nepal and Pakistan. This should not happen in a first world country and if it had been practical solution we would have got out and walked!!
