Reaching Oasi Zegna Park is easY: you can pass either through Biella or through Cossato-Trivero. In both cases, you just have to follow the many signs and you'll reach Bielmonte without any problem.

If you're coming from the motorway A4 (Turin-Milan), the closest exit is Carisio (or Santhià, if you're coming from Turin), if you're on the A26 (Genova-Gravellona T.), the exit is Romagnano Sesia.
