From the S. Michele cable car station go downhill for about 250m and take the first road on the right going uphill towards Faigolo.
When you get to Faigolo, at the fork in the road take the road on the right towards Prai. The uphill trek starts from here, about 3km long and of around 20% steepness which will take you around 2 hours to complete. The path is loose packed and shaded and, in places, quite muddy.
It has wonderful views over Lake Garda and Malcesine.
When you get to Prai, keep right and go downhill for about an hour passing Signor back to S.Michele from whence you started the walk.
