This great gravel ride passes seven Cols (all well above 2000 metres) and three lovely little Alpine lakes. It’s primarily in Italy but it sneaks into France once and rides past a lot of border posts. This requires a mountain bike. The vast majority of the ride is on mediocre quality but beautiful/quiet gravel roads – although I occasionally took some trails to link cols.
