No holiday in the Valtellina valley is complete without a ride on the Bernina Express (Rhaetian railway). The panoramic carriages with the unmistakable red hue of the Bernina Express begin their journey in Tirano, crossing the border between Italy and Switzerland, through the Valposchiavo valley with truly enchanting scenery to behold (do not miss the Brusio spiral viaduct). Then, it climbs up to an altitude of 2253 metres to the Ospizio Bernina station—experiencing inclines of up to 70 permille—before the descent to St Moritz.
