When the Belmond Andean Explorer service through the Peruvian mountains launched earlier this year, headlines proclaimed it 'the most luxurious train in South America'. And for those keen on seeing the Andes' high altitudes in serious comfort, the hype is justified.
Passengers - up to 48 at any one time - can expect mahogany panelling, chandeliers and plush compartments. There's even an on-board library, for those times when staring out of the window at the cascading highland scenery doesn't cut it. But such moments should prove few and far between.
Starting in the one-time Inca stronghold of Cusco (gateway to the Sacred Valley and Machu Picchu), the route takes in natural marvels such as Lake Titicaca - the planet's highest navigable body of water - and Colca Canyon, a ravine twice as deep as the Grand Canyon and well primed for spotting Andean condors. It almost goes without saying that the route forges one of the highest railway lines in the world (over 4,250m in places).
The terminus - or start-point, depending on which direction you travel - is Arequipa, a city arguably less well known than Cuzco but just as spectacular on the eye. Ringed by volcanoes, its UNESCO-listed historic core is a vision of baroque buildings created from local white igneous rock. Pay a visit to its vast cathedral, which was first founded in the mid-1600s - even earthquakes and rebuilding work haven't dimmed its glory.
