Osier is a populated place in Conejos County, Colorado, USA. It is an old railroad settlement and train stop approximately halfway along the Cumbres and Toltec Scenic Railroad where trains from both ends of the line meet and stop for lunch, making it possible for passengers to either continue in the same direction or return to their point of origin afterwards. This location by the river was the halfway point on the old toll road from Conejos, Colorado, to Chama, New Mexico, and can be reached by Forest Road 103 from State Highway 17.
