On lonely paths from the Reschenpass to Tirano / CH and Italy: Once across the Alps! On this trekking tour we dedicate ourselves to the southern part of an Alpine crossing and follow a rather unknown route from South Tyrol to the Italian province of Sondrio. We hike on lonely paths from the Reschenpass through the UNESCO biosphere reserve Val Müstair into the upper Valtellina. Wild and romantic climbs lead us to the Dosde Hut and over the Viola Pass into the Val Campo. We continue past the idyllic lakes into the Bernina Group and down into the Poschiavo valley. We get to know the diverse aspects of these original mountain regions.
