The Rollercoaster is one of the classics of the Finale Outdoor Region: an enduro trail in the Melogno area, number 170 on the official map, rated between intermediate and difficult.
It is a heavily shaped trail, long and fast, full of compressions, berms and small jumps: its managers describe it as pure flow. The ground is moderately rocky and often dusty, and it rides best when slightly damp.
Given its length, pace yourself and don't ride the brakes all the way down. Before you set off, check on the Finale Outdoor Region website that it is open: trails close for maintenance, races or bad weather.
