Anyone got any "must ride/must see" roads between H of H and Croatia. Particularly keen on roads alongside rivers, stunning views etc… We haven't fixed a route yet, as we like to travel "on spec" but always glad to receive recommendations. May go out via Czech and down through Austria and back Northern Italy/ France or even Switzerland. Best Alpine pass any one?
…and before anyone moans about “planning your own route..blah, blah, blah….” I am perfectly capable of reading a map and have done many continental trips… I’m just looking for guidance for the tourist in me…..OK?

...and we're off in about 19 days or so...
