This is an incredibly scenic tour suitable for both skis and snowboards. Two relatively short ascents give a lot of descent for your effort.
From the Pischa top station over the Pischagrat to the Pischahorn. Then descend into the Novaier Tälli before once again climbing to the pass betweem Gitzihöreli and Lauizughorn. From here you can enjoy a 1200m descent to Monbiel and follow the XC ski trail back to Klosters.
This tour is in unprepared and uncontrolled terrain. The tour crosses through or under terrain over 30 degrees (sometimes over 40 degrees) a number of times. It is possible to get into a valley that it is not possible to get out of without entering either critical terrain or having to retrace steps up a long and steep slope. This tour should only be attempted in safe conditions by people with experience in assessing avalanche risk.
