Aguas Calientes is the town at the end of the railway to Machu Picchu. It's basically a conglomeration of hotels and restaurants that hold tourists between arriving/departing on the train and the bus trip up to see the ruins. We were lucky enough to stay at a hotel at the edge of town that had a few acres of grounds. Hotel staff put out feeders to attract the local birds. I was unaware of the variety of birds in the area so was very pleasantly surprised to see as many as I did.
