I am thinking late July / early August. It has to be when the kids are out of school and when the snow has melted on the passes. I am leaning toward Durango as the base because it has more amenities and attractions than Creede (which is really nice but very small and somewhat isolated). Durango is close to Mesa Verde NP and has the Durango Silverton Railroad. Additionally it is closer to the better Jeep trails (around Silverton, Ouray and Telluride). We can easily run Engineer, Cinnamon, Ophir, Imogene, California and Corkscrew in just about any 4WD. For those looking for a little / lot more thrill we can run Poughkeepsie and Black Bear (although my wife has advised me she will never do Black Bear again and I won't do it with the kids). I have stayed at Alpen Rose and the KOA in Hermosa in the Durango area. Does anyone have a better recommendation in Durango?
