We ride the train one day (going from Chama to Antonito) and chase it two days. One day being from Chama to Osier and Sublette and the other day (in the morning) we chase it on the Antonito side to Sublette. The dirt roads are easy, providing us with another way to see the train.
As for camp, we stay at a spot above the old track maintenance town of Sublette, NM. A wonderful spot against the aspens with good views of the San Luis Valley and the Sangre de Christos. We stay at the same camp for the trip.
