The best way to get to the Umbrail Pass is by postbus, but the 1,125-meter climb can also be done on the mountain pass road by bike. The difficult part of the ascent, however, begins only after the top of mountain pass road. On a single trail, bikes need to be pushed and carried over 500 altitude meters up to Piz Umbrail at 3,033m above sea level. The ascent is strenuous but pays off.
The descent to the Lai da Rims is alpine entertainment of the highest level. The well-rideable trail winds through rugged mountainous landscape. After Lai da Rims, the route becomes somewhat more technical and is scattered with many turns, but is nonetheless good and fun to ride. Finally the stream is reached in Val Vau, at which point a descent of more than 1,000 altitude meters has already been driven. Many already know the subsequent final section from other tours into the well-known Val Mora. The next trails first avoid a gravel road which then subsequently has to be taken until a mountain ridge is reached, where a new trail branches off to the right through dense forest to the village of Santa Maria.
