The Mountains of Mirkwood lay in the central parts of northern Mirkwood, north of the Old Forest Road.

A jumble of fir-covered, low-lying hills to the west rose to greater heights in the east, together forming a range nearly one hundred miles in length.[1]


Oropher was also disturbed by the reports of Sauron's rising power and by the end of the Second Age, he ruled his Woodland Realm from the western glens of the mountains and his numerous people lived and roamed in the woods and vales westward as far as Anduin, north of the ancient Dwarf-Road. They knew the range as the Emyn Duir, the "Dark Mountains".[2]

During the Third Age, the power of Sauron spread across the Mountains as it did throughout the rest of the Forest. The Silvan Elves removed to the far northeast of the Forest and the mountains became populated by hideous creatures. Just as Greenwood the Great was renamed Mirkwood at this time, its northern hills also took on a new name: Emyn-nu-Fuin, the "Mountains of Mirkwood".[2]

After the passing of Sauron and the cleansing of Mirkwood, Mirkwood was renamed Eryn Lasgalen, or the Wood of Greenleaves. Thranduil took the area from the northern eaves of the forest south to the Emyn Duir for the Woodland Realm.[3]


The original Sindarin name Emyn Duir ("Dark Mountains") referred to the growth of fir trees on their slopes, without any evil connotations of Darkness.[2] The later name Emyn-nu-Fuin literally meant "Mountains under Night".[4]
