You are assigned to an enclosed train car, but then can select your own seats. Each enclosed car also has an outside observation car you have access to. Very nice.
The route follows the Verde River up into a canyon area. None of it is accessible except by four-wheeled drive over almost non-existent roads. It is unusual to see water in a river in Arizona this time of year, especially since there has been almost no rain in several months.
Overall, just a very pleasant, relaxing day out!
