it depends of your lvl and the way u hunt. If u have a good team and lvl enough to hunt at ferumbras ascendent quest that is the best place, as Zupa already said.
If u can't handle that u can go to Oramond swers, where I did myself, Paladins can hunt there easily lvl 350+, or hunt with team.
Demons from Yalahar are a good option if u hunt alone and are 200-
