May I ask my gods, can the Jetta take the Duku Highway?

Yes, there are more winding roads on the Duku Highway, and you may feel a little less dynamic when climbing a hill, but there is no problem walking the whole way.

No problem, any car will do, the road is mostly in good condition. I think the difficulty of the Duku Highway is the weather, there may be snow or landslides. Under normal circumstances, driving on the road is no problem at all.

Basically, they are all roads, as long as the site is not too low. In the event of landslides, the road will be closed and people will not be allowed to enter.
