River Withywindle

A minor tributary of the River Baranduin or Brandywine. It rose above the house of Tom Bombadil and flowed approximately southwest to cut a valley through the trees of the Old Forest, before it met the Brandywine at Haysend near the southern edge of the forest.

Old Man Willow grew on the banks of the river, and through his malicious power the valley of the Withywindle was the most dangerous part of the Old Forest. Through his power over the trees, the Great Willow would draw unwary travellers to his domain on the banks of the Withywindle.
