The «Trans-Altarezia» is considered potentially the most attractive multi-day mountain bike tour in Graubünden. At each of the four to five stages there are highlights such as the Fimberpass, the Val d‘Uina, and the Bocchetta di Forcola that approaches the Val Viola or the route to San Romerio in Val Poschiavo.

Ideally, you will start the „Trans Alta Rezia“ in Scuol, catching the postal bus towards Samnaun, and then getting on the gondola to Alptrider Sattel. This stretch is still hard enough, so this first ascent can be replaced by the train journey with a clear conscience. The tour starts with a highlight, the wonderful single trail over to Zeblasjach. Later, you reach the Heidelberger Hütte, a mountain hut from which point you will have to push your bike onto the Fimberpass. Now you will enter onto the bumpy single trail to the Val Sinestra. After Zuort, a magnificent single trail with impressive hanging bridges runs along the valley floor toward Ramosch and onwards toward Sur-En. It is advisable to make your first camp either here or in nearby Scuol.

The second day is dedicated to the Val d‘Uina. A steep little road runs the length of the narrow valley until high up, near the top, the famous cliff path begins. You will have to push your bike for this section; in doing so, you will be at your leisure to enjoy the surreal cliff-side world that one finds oneself in here. After the rocky passage, you roll down over the Schlinigpass to Sesvennahütte and later on continuing to the cart part toward Schlinig. We continue along the Melzbach to Schleis, further toward Laatsch and on the final climb into the Münster Valley. The second stage ends in Müstair or in Sta. Maria

On Day Three I am starting the journey onto the Umbrailpass. You can master the arduous 1100 metres of altitude with the help of the postal bus. On the Umbrailpass, you go up a flowing single trail on high to Bocchetta di Forcola and later you reach the Bocchetta di Pedonolo, which represents the peak-time departure point for the Cancano Lakes. As a result, a ridgeway that is as flat as a pot‘s lid leads to Arnoga. We elongate the stage with the Pass da Val Viola, and with the departure to Poschiavo. The beautiful climb through the Val Viola is quite feasible, even if the way is very steep at the end. All the more fun is the exit. The trail was expanded a little extra for mountain bikers and leads past the uniquely beautiful lakes in the Val di Camp. On the section after the Rifugio Saoseo, a good amount of driving skill is again necessary, where the trail passes further below into a delightful flow trail down to the valley floor at Poschiavo.

The final stage leads over San Romerio to Tirano. After the first stage of ascent, the path goes from beneath Cansumé into the first wonderful single trail along the height, then there is again a ramp to Sclupetoir and then the world-class trail across to San Romerio. In the up-and-down on the gravel road, we continue on to the green border to Italy, where again a successive first-class trail is in place over Roncaiola to Tirano. Go back to Scuol from here with the help of the Rhaetian Railway.

Tip: The route is fully sign-posted as a mountain bike trail (32 - Trans Altarezia bike route), whereas the route suggested here differs in a few portions in order to raise the amount of time spent on a single trail.
