The Bric Colombino is an easy dirt road that Spotorno riders also call "Pannelli Bassi": number 293 on the Finale Outdoor Region map.
It runs from the Quattro Strade junction below Vezzi Portio to Passo Stresso and can be ridden both ways.
It is a cross-country route with fun ups and downs through a lovely oak wood. Before you set off, check on the Finale Outdoor Region website that it is open: trails close for maintenance, races or bad weather.
