I think Kendenton went to Mugello last year and posted a trip report here on ST.N.
If I only had a week or so for riding, I would stay in Tuscany and explore the hill towns. Just Google Tuscan hill towns. While there are some nice riding roads in Tuscany, there is also a lot of towns and thus, a lotta traffic. Nothing wrong with that as long as you ride in tour mode rather than sport mode. The Chianti Region has pleasantly twisty roads and scenic hill towns. The Val d'Orcia has the classic Tuscan landscapes that you see in travel brochures. I stayed at the Cisterna nel Borgo
in Rocca d'Orcia, run by a young couple. The wife speaks English. Passo della Futa between Mugello and Bologna was part of the old Mille Miglia road race route. Just north of Tuscany is the Cinque Terre region with its picturesque villages clinging to the mountainous coast.
The foothills of the Alps can be reached via a 6 or 7 hour blast up the autostrada, which will cost you a day. decisions, decisions
The same goes for the south of France. The Italian Lake District is very romantic and will score you points with the spousal unit, but the congested roads around the lakes aren't conducive to sport riding.
