Colorado Springs RV Parks and Hy 160 from Alamosa to Durango

If you have time I would recommend the Cumbres & Toltec Steam Railway. Great scenic trip.
If you should do it, I recommend taking the train from Antonito to Chama and the bus back. Or take the bus from Chama to Antonito and the train back. The route from Antonito starts in the semi arid valley, climbs into the mountains, over passes, than down into the mountain town of Chama. Quite a dramatic change in scenery as you go along. I think it would be a little anticlimatic the other direction.
