Mancos Valley is tucked between Mesa Verde Nat'l Park and the La Plata mountain area of Durango. This is ranch country plus thousands of acres of national forest, fit for outdoor adventure all year long. McPhee Reservoir in Cortez is 2nd largest lake in Colorado; good fishing, because it's the Dolores River. Golfing is good in Durango, Cortez, and Farmington. Mancos is a perfect base camp for historic and archeological wonders throughout 4 Corners and along Trail of the Ancients.
September is balloon fest time in Mancos (enlarge)
