This is a high alpine pass commencing on a glacial lake shore with a relaxed climb up to a prominent outcrop, then descending to the alpine railway station. The footing is gravel track leading to well-marked paths which become stony and zig zag frequently.

Take a short ride on the UNESCO listed Bernina Bahn, a train line which equals the Glacier Express for stunning views.  Getting off at Bernina Hospiz station, follow the easy circular walking route skirting Lago Bianco to Alp Grum and hike up to the mountain hut at Sassat Mason. The peace and tranquillity of this area is inspiring. Return to Pontresina by train. Ospizio Bernina/Bernina Hospiz Station Is a stop on request only station, listen for the announcements, one of which will be in English.

Piz Bernina

Piz Bernina, 4049m and ranked 5th in the Alps, forms part of the watershed between Switzerland and Italy. The mountain separates two glaciers, Vadret de Tschierva to the West and Vadret de Morteratsch to the East.

Lago da Bianco

Lago da Bianco, the “White Lake”, was formed when the two natural lakes, Lago Bianco and Lago della Scalla were both dammed. The associated hydroelectric system has powered the railway from its inception.

The Bernina Line

The Bernina Line was first established 100 years ago and has been a UNESCO World Heritage site since 2008.
