The Passo Rombo, or Timmelsjoch, is one of the international border crossings between Austria and Italy, and one of its highest at 2474 metres. In the past it was a strategic crossing, but these days most traffic between the Tirol and Italy goes by the Brenner Pass, which leads into the Italian autostrada network and is passable at most times of the year. The Passo Rombo is not passable in the winter, but for most of the summer months it provides a very scenic way to travel between the two countries. Be warned that like the Brenner motorway pass it is a toll road; in June 2013 cars were charged €13 one way, payable about 5k north of the border. .
Allow plenty of time for your drive, since the Italian side is particularly narrow and needs due care and attention. In summer there are plenty of cyclists and motobikers around, and extra care is required.
The pictures were taken at the end of June 2013, and the temperature was about 7C.
