The Toltec Gorge area is one of the most spectacular sections of the old D&RGW Line between Antonito, Colorado and Chama, New Mexico. The railroad runs high on the mountainside, with a deep gorge on the south side....in this case, the Fireman's side....of the train. In late September and early October, the spectacular view from the train is enhanced by an explosion of color as the Aspen trees light up the hillsides in beautiful gold and orange colors. The view can be a little scary for those that have a fear of heights, however. Folks who are a little squeamish in that regard had best ride on the RIGHT side of westbound trains.
