“The lift service road passes through the forest before ending at a mountain hut.”

This is a short gravel road that connects the upper station for the Col Rasier lift with the Pieralongia lift. The Col Rasier lift doesn't allow bikes.
It's a bit of a steep climb if you're starting at Col Raiser, but the road is above the tree line, so the views of the surrounding mountains (the Geisler and Stevia groups directly in front of you) are quite impressive.
You can also continue downhill from Col Raiser on the Odles - Rifugio Firenze (4)
gravel road. A steep singletrack (also trail 4) continues downhill from Col Raiser, but this section is not recommended for bikes.
