Redwater Den is a location in The Elder Scrolls V: Dawnguard. It lies west of Boulderfall Cave, between the Atronach Stone and Faldar's Tooth. From above the surface it appears to be just a ruined cottage, but it has a trapdoor which leads to an underground area. It appears to be some sort of drug den; the place is littered with empty skooma bottles. There are people coughing, and tendrils of red smoke swirl in the air. Further into the depths, skooma is being made. It is a great area for acquiring rare potions, such as Redwater skooma, skooma and Sleeping Tree sap, as well as moon sugar. They respawn every eleven days.
