Trollshaws

The Trollshaws are the upland woods, consisting at least partly of beech trees, that lay to the west of Rivendell between the Rivers Hoarwell and Loudwater. They were the haunt of trolls. Three of these trolls waylaid Bilbo and his companions during the Quest of Erebor. Years later Frodo and his companions found them on their way to Rivendell, but they were inert stone.
