This guide shows you one or more of the best and most efficient routes to farm Fel Iron Ore in World of Warcraft Classic and is exactly what you need if you want to gather materials yourself instead of spending your gold on it on the auction house. If Fel Iron Ore is not what you are looking for, you may take a look at all available farming guides.
Farming Fel Iron Ore on Hellfire Peninsula
Hellfire Peninsula is the best area to farm Fel Iron Ore because there are no Adamantite Deposits here. The respawn rate of the deposits should be enough that it is not necessary to permanently fly (or ride, as the case may be) over the entire area. Of course, you can choose which path to follow. The basic rule is always: stay at mountain ranges or around mountains, because only there (or in caves) you can find ores.
This route covers the second half of the Hellfire Peninsula.
Farming Fel Iron Ore in Terokkar Forest
If you don’t mind getting some Adamantite Ore on the side, Nagrand is a good place.
If the first route is overfarmed, here is a (less attractive) alternative:
Farming Fel Iron Ore in Zangarmarsh
Zangarmarsh are a good alternative to the Forests of Terokkar, although the amount of ore might end up being less. However, it’s very easy to follow this route, you don’t really have to pay attention to anything here.
At the very northwestern end on the small island is a cave, you should look into it as well as the cave in the south, because you can’t always see the ore deposits from outside on the minimap.
