The Andean chain is immense - to see even the small part we did, we spent over two weeks of our lives on buses travelling 14,000 km up and down the length of South America. That was an experience in itself, ranging from the luxury of the cama buses where you can sleep almost horizontally as they cruise through the long desert night to the clapped out Bolivian clanger, full of locals, produce, livestock and the smell of burning brakes as it creaked down the winding dirt road into a ravine.
We also travelled 2400km by car, 60km by train and 1500km by ship to get to and from places. When we reached our destinations we sailed 500km in a yacht, 200km on a riverboat, 20 km in a zodiac and 10km by kayak, rode 50km on mountain bikes and 30km on horseback, not to forget short positional changes by chairlift, tiroleser, swimming or simply sliding on our backsides down the snowdrifts of a volcano using an icepick for a brake.
