Plaun da Lej - Blaunca - Piz Grevaselvas - Sils-Baselgia

From the orientation point of view, the tour causes little difficulty.

From Plaun da Lej you can warm up on the road via Grevaselvas up to Blaunca.

The section from Blaunca up to Plaun Grand is not marked, but easy to find. In Blaunca you turn right before the bridge, follow the path between the houses and come directly behind the houses to a rock slab (glacier cut), which is exposed to SE. If the wind can be endured, this is a nice resting place. From here you can see the path that pulls up orographically to the left of the stream, first in a serpentine to the right. Just follow this path until you reach Plaun Grand with the signpost. 

From there you simply follow the marker up to Lej Nair, from there continue to the NE saddle of Piz Grevaselvas and then turn left hianuf to the summit. The climb is quite steep. Above the lake there are longer passages over glacier cuts. Below the saddle there is also a block passage.

Due to its height and its location close to the triple watershed, the Piz Grevaselvas offers a great panorama to N, W and S. Only in the E does the Piz Lagrev "disturb" something. The only drawback in the view: from the Upper Engadine lakes you can see relatively little. If you value it, you have to switch to the neighboring Piz Lunghin (200 m lower, maybe a bit lighter).

On the descent you follow the same route to Plaun Grand. There the signpost leads you to the left towards Grevaselvas. Always following the marking you reach the small saddle north (above) of Grevaselvas. If you want, you can of course descend from here via Grevaselvas directly to Plaun da Lej.

To leave and because of the views, however, it is recommended to descend to the left, following the Via Engiadina, down to Sils Baselgia. The views over the lake are unique and the mostly pleasant slope is as I said just right to run out after the long tour with steep passages in the ascent and descent.
