Adventure Park Lago d'Orta le Pigne Italy, wrong location

I went to this location:

Adventure Park Lago d'Orta le Pigne.

Butt it's on the setting side of the Mountain and it's zending me into the wrong direction of a one way street!

I had to revert to Google maps which had the right location.

The people at the park told me, this problem exists in a lot of navigation apps and until recently also in Google maps.

Please solve this for future tourists?
