From the station in Pontersina (1774 m) take the Val Roseg unpaved road. The road is closed to traffic but a service of horse drawn carriages is available. From Hotel Roseg follow a marked trail along the bottom of the valley to Alp Ota Suot. From here begin the climb towards the right that brings you to Margun da l'Alp Ota (2257 m). On the right go up over curves to then follow a gradual diagonal towards the south, passing by the level area of Plaun dals Suts (2679 m). Descend a gentle slope to the slopes of the moraine below the western part of the small glacier of Roseg and, making a last arc towards the southeast, you'll come to the mountain hut. b) From the intermediate station of the Corvatsch gondola (2699 m) take the road that runs halfway down the mountainside and follows the head of the moraine valley of Murtel in a semicircle towards the east (signs). This takes you to the opposite side below Fuorcla Surlej (2755 m), which you get to after a short climb. Just below the pass, on the opposite side, take the trail that turns off on the right. This takes you due south first with a gentle descent then levelling out below Piz Corvatsch at 2569 m (2 hrs; marked trail E).

From Hotel Roseg keep to the bottom of the valley until you get to the small glacier of Roseg, which you then follow for a short way to 2400 m of elevation. Ascend the lateral moraine on the left and follow it, heading for the base of the rocks of Plattas then up to the mountain hut. It is also possible to go around the butress on the right to come to the summer trail in the last meters.

To Chamanna Tschierva 2583 m. Route over moraines and detritus. It's not easy and is often impossible due to the necessity of crossing the large rivers that come from the Roseg and Sella glaciers (E; 2 hrs). To Marinelli-Bombardieri 2813 m. Long but magnificent route mainly on a glacier (F; 5 hrs).

To Pizzo roseg 3973 m, along the "Via Normale" (normal route). Elevation Gain: 1300 m. Time: 5 - 6 hours. Difficulty: PD+. First Ascent: A.W. Moore, Horace Walther and Jacob Anderegg on July 28, 1865. Route: From Chamanna Coaz (2610 m) go up on the small glacier of Roseg first towards the south and then in an arc heading southeast and east. Climb over the outcropping (3057 m) on the ridge that divides the glacier from the small glacier of Sella. From Vadret da la Sella head east nearly to the slopes of Piz Roseg (around 3200 m). Here you'll find the southernmost outlet gully of the small hanging glacier suspended below Spalla at 3598 m (F; 2 hrs). From here you can also get to Parravicini bivouac by going up the nearby Sella Pass and down the small glacier of Sella (F; 1 hr). Go back up teh gullly to the glacier adn continue along an ever steper incline to enter a small steep gully that takes you to Spalla (1 hr and 30 min; 4 hrs - 4 hrs and 30 min). Now following the wide snowy northwest ridge come to the false northwest summit. Go down to the saddle below and climb it over the easy but unstable rocks that take you to the top.
