I guess what she wants to say is called {}.
It implies a road through areas such as forests, bushes, hills, etc. only wild animals like boars, bears, mountain goats take.
In a metaphorical sense, is used to describe an unusual lifestyle such as a life taking a risk other people would not want to. Ex) being an entrepreneur, not choosing the career path your friends usually go, teachers recommend, or a firm prepares, etc. which is different from the road well-maintained.
"Bushwalking" in Australia or "Death Road" in Bolivia seems dangerous to me, but normally there are tour-guides or fellow travelers with you. Again, probably she wanted to describe the road which it seems no one has ever taken, not well-maintained, savage, and so on.
