National Park Bike-Marathon [SwitzerlandMobil no. 444]

The route leads from Scuol through the Val S-charl, past the Swiss pine forest God da Tamangur to Alp Astras and then on a flow trail over the Pass da Costainas (2251 m). Then on to Alp Champatsch and along the forest road to Lü and Tschierv.

From Tschierv follows a longer section through the forest to Valchava before the long ascent to Döss Radond (2234 m). The gravel road then leads into Val Mora with its famous singletrail to the Swiss-Italian national border. From the border, the path continues to Lago San Giacomo and further over the Alpisella (2299 m) to Livigno.

From Livigno, a very steep climb leads to the summit of the tour at Pass Chaschauna (2694 m), from where a perfectly groomed singletrail leads to Alp Champatsch. From S-chanf begins the 'easiest part' of the tour through the Lower Engadin villages past Zernez, through Susch, Lavin, Guarda and Ftan back to Scuol.
