Globe Trekker Zay Harding ski tours the legendary Haute Route from Chamonix to Zermatt, traversing three Western European countries: France, Italy and Switzerland, and taking in Mont Blanc and the Matterhorn along the way. The trek begins with a training day on the world’s steepest and longest ski slope: La Vallée Blanche. After meeting up with his Irish mountain guide - Robbie Fenlon - Zay takes the highest cable car in Europe. Zay temps fate and frequent avalanches, masters the technique of off-piste skiing in powder-snow and learns how to negotiate his way out of a deep crevasse. Zay also visits a local cemetery where thousands of intrepid climbers have lost their lives in pursuit to concur the Alps.
