On the journey, the train makes a gentle climb to higher, and cooler, altitudes. The first half of the journey is dominated by the magnificent Andean mountains which towers over the deep valleys of the meandering Huatanay River. It then reaches the gentler, rolling Andean Plains, where vicuña and alpaca can be seen. If travelling aboard the Andean Explorer, the glass-walled observation car provides the perfect opportunity to view the beautiful scenery.
