Get on board with the Rio Grande Scenic RR. They offer trips in three directions from Alamosa. The staff has a great vibe -- they want you to ride with them and are proud to show off the equipment and the scenery.
We rode to LaVeta, the longest trip - it takes the full day (9 - 5). We recommend the dome car for the view and the seats. Dome passengers are welcome to wander the train.
Our conductor Steve was informative and funny. The rest of the crew was equally excited and enthusiastic.
