Lost Valley Redoubt is a sprawling ruin at the southwestern portion of The Reach and is located about halfway between Markarth and Falkreath. It is situated at the river-head of the Karth River. The ruins are home to an encampment of Forsworn and Hagravens. At the top, by the waterfall, near Bard's Leap Summit (behind hide screens), a Word Wall is guarded by two Hagravens.
