The H, also known as the Sentiero delle Neviere, is a Base Nato classic and one of the first trails built in this area: number 91 on the Finale Outdoor Region map, rated difficult.
It starts from the old helicopter pad, now disused, and heads straight downhill: fast and flowing, in the style of the other trails in the area.
On the way down it crosses a dirt road, and at the bottom it comes out onto a tarmac road: take care there. Before you set off, check on the Finale Outdoor Region website that it is open: trails close for maintenance, races or bad weather.
