Ride the Devil's NoseAlausi, Ecuador
For the engineers tasked with building a train line between Quito and Guayaquil at the beginning of the 20th century, the mountainous terrain of the Andes presented a challenge. The completed route traverses gorges, rivers, forests and a particularly harrowing mountainside descent known as the Devil's Nose, where more than 2,000 workers died during construction. The train winds down a sheer, rocky slope, travelling more than 500 vertical metres in a 12-kilometre journey, during which passengers are treated to breathtaking views of what is known as the Condor's Aerie.
In case the idea of riding a century-old train route down what is essentially a cliff makes you shudder, don't panic – the tracks and carriages have been refurbished, so you can white-knuckle your way down the mountain in comfort.
A three-day tour of Cotopaxi Volcano, Devil’s Nose and Cuenca costs US$765.
As far as train rides go, this is pretty intense, so hold on tight!
Ask for a seat on the right hand side of the train for the best views.
