After the second fall of Sauron, which was the most dangerous area of Middle earth?

I am asking this because conflicts happened among the free people of Middle earth in the fourth age.

For example: Harad? Rhûn? Misty mountains?

I would probably list all of those places as being dangerous, but probably the Misty Mountains/Moria would have been pretty nasty, as would Minas Morgul when Faramir had to go clean that place out.

moria for sure, i highly doubt the goblins would give a toss about whether sauron was there or not, they didn't follow anyone

I have to disagree about Moria. King Durin VII expelled the goblins, and from then on there were Dwarves in Moria until the end of Middle-Earth, according to Tolkien.
And Harad was conquered by King Elessar (Aragorn) after he became King not to mention the reclamation of Arnor when he reestablished the North Kingdom., and the Dunlandings were probably crushed by the Rohirrim. Rhun probably fell to the Men of the West as well.

What about Forodwaith? It was just snow and ice there, roamed by wargs and spirits.

Mordor. Last I heard it was 10 feet deep in lava.

It depends on what you think of as "dangerous". If by dangerous you mean that there are creatures about that want to kill you, That'd be the eastern lands before they were overthrown, and Forodwaith after that, with Wolves and Spirits about, as Ingold said. If by dangerous you mean Hazardous, the Mountain ranges in Middle earth are still a place you can fall off very easily.

I put this doubt, because really Rohan and Gondor fought hardly in campaigns.

Even so, I think the Misty Mountains, Harad, Haradwaith, Forodwaith and the Mount Gundabad were very hostile areas during the fourth age.

Yes I understood what you said because Erebor became a peaceful place after the battle of Dale.

You wanted to say concerning the mountains of the north! Am I right?

Angmar would've been dangerous as well as the Barrow-Downs.
