Takayama-Hokuriku Area Tourist Pass

Good evening,

May I know whether I can make use of the Takayama-Hokuriku Area Tourist Pass to go to Gokayama since the Nohi bus passes Gokayma before Kanazawa.

Thanks

No, the Nohi buses do not stop between Shirakawago and Kanazawa. You have to take a different bus to go to Gokayama, which is not covered by the pass:

To be more accurate: Two buses per day from Shirakawago to Kanazawa do actually make a stop at Gokayama, but passengers are only allowed to board the bus at Gokayama. Alighting is not allowed:
