As an alternative to the Brenner highway highly recommended. Always a slight up and down. Only at the beginning there are a few steep climbs. Matrei then go on the Brenner highway. Until then, very little traffic.
Couped, winding road in good condition with great views of the Brenner motorway, surrounding mountains and the valley. Not unappealing to drive. Hardly motorized traffic and lots of sun in contrast to the valley.
