We recommend the use of an adaptable MTB with 29-inch 110-mm wheels and a flexible gear ratio (e.g. 28-36).
The tour we are suggesting in the Valtellina area involves a distance of 40 km on well-marked roads.
This is where one of the most amazing Gran Fondo competitions in Lombardy, the event which takes its name from the Alta Valtellina, has been staged over the last six years (the exception being the 2014 race).
Mount Stelvio, Campolongo, Mount Solaz (2050 metres)
Starting again from Bormio, at a height of 1195 metres, we head towards the village of Piatta, and then take the road for Campolungo, where we cross the Stelvio ski run.
From here on, the road becomes rough, with a series of gentle ups and downs followed by the climb towards Calvarana. The views are superb when you emerge at the top above the tree line.
You feel as if there is nothing between you and the sky, and you can gaze out over the Stelvio National Park and surrounding peaks.
The descent is on a dirt track as far as the FurvaValley, where we get to Teregua. Here we join the Ables military road, which takes us up Mount Solaz, to a height of 2050 metres.
We then descend towards the Zebrù Valley and cross the Valfurva road, following a spectacular single-track route which takes us through Stelvio National Park and back to Bormio.
This is a really beautiful circuit, clinging to the slopes of Mount Stelvio, climbing and descending in the immense silence of the National Park, with an overall change in level of 1430 metres.
We will definitely return.
