Tips from the Community
Since, as is often the case, the pass signs are completely covered with stickers, taking photos in front of them is no longer fun. Alternatively, you can use the boundary stone to take a "proof photo." On the other side of the road, there's another, smaller stone with the elevation: 2113 m.

Montespluga SO The mountain village of Montespluga is located at an altitude of 1908 m above sea level at the beginning of the Val San Giacomo (also called Valle Spluga), about three kilometers from the summit of the Splügen Pass. The place originated in a hollow rich in water and pastures, where the Valle Spluga meets the Val Loga, near the border peaks of the area such as Pizzo Tambo. In 1927, the construction of the dam about 2 kilometers south of Montespluga began, damming the Torrente Liro to form the Lago di Montespluga below the village. The village with its few houses, restaurants, hotels, and shops on the pass road and the old customs building "La Casa" has hardly changed. Until 1841, it housed the only hospice on the Splügen Pass and the only place of worship, the chapel of San Francesco d’Assisi. The latter was consecrated in 1832, the year after the completion of the new road to the Splügen Pass in 1822. As early as 1767, the apostolic nuncio in Switzerland and later Cardinal Luigi Valenti Gonzaga had granted permission to set up a small chapel in the hospice. Since the opening of the San Bernardino Tunnel, the pass has no longer been kept open in winter. The village, which consists of three streets (Via Dogana, Via Ferrè, and Via Val Loga), can be cut off from both Italy and Switzerland. Montespluga is the starting point for numerous hiking, mountaineering, and ski touring destinations in the surrounding mountains and a stage destination on the cross-border long-distance hiking trail Via Spluga.

Gallery at the Splügen Pass / La Galleria from 1843 Historic avalanche gallery at the Splügen Pass The historic avalanche gallery on the north side of the Splügen Pass was completed in 1843 and made it possible to keep it open in winter even in critical conditions. After the Second World War, the Splügen remained closed during the winter months and the gallery was bypassed with a summer road. The gallery has been restored in recent years with a restoration project so that at least hikers can use it again safely.

Beautiful highlight of the crossing from Sufers to Andeer (or vice versa). Hardly any traffic, great panorama including a world view of the Piz Tambo.
