Up and down trail, on the main route of the well known monte Canto alto in Bergamo.

start and finish in Bergamo (Accademia Carrara)

Start at Bowness Knott car park and run anticlockwise around the lake along the footpaths, tracks and roads. Around most of the route, you can see the start point but cannot get there without completing it - no cheating or taking shortcuts here! Stunning views and a mixture of road, path and trail running with some scrambling make this route challenging but awesome in its beauty.
