Blanc massif is now a significant tourist destination. The region attracts over sixmillion people per annum, with around one in five gaining access to its slopes by means of mechanical infrastructure (cable cars or funicular railways). Some surveys have shown that tourists mostly come to the Mont Blanc massif and its environs for winter sports such as skiing as well as summer outdoor activities like hiking, climbing and cycling. The Aiguille du Midi Cable Car in Chamonix attracts 500,000 people each year and gives views over much of the massif, and up towards Mont Blanc itself. From Chamonix it rises to the summit of the Aiguille du Midi at , and holds the world record for the highest vertical ascent of any cable car (). The building of the new Skyway Monte Bianco cable car on the Italian side of the massif is expected to increase visitor numbers to Courmayeur from 100,000 to 300,000 per annum, following complete replacement of an earlier cable car system in 2015. It takes tourists from La Palud up to the Torino Hut at its top on Pointe Helbronner. Costing over 105million euros, the Skyway Monte Bianco is regarded as the world's most expensive cable car installation. Other recent enhancements to tourist infrastructure across the massif have included construction of a new, and ultra-modern Goûter Hut to accommodate the increasing numbers of mountaineers attempting the popular Goûter Route to the summit of Mont Blanc, and investment of ½ billion euros in Les Grands Montets and other ski areas over a six-year period from 2014 onwards. Increasing numbers of mountain tourists, ease of access into the high mountain environment, plus promotion and encouragement by tour companies offering ascents of Mont Blanc to people with little or no previous alpine experience, have led to an increase in mountain accidents and even inappropriate demands to be rescued. With up to 30,000 climbing parties now attempting to ascend Mont Blanc each year, it has gained the reputation of being one of the world's deadliest mountains. Deaths from mountaineering-related accidents across the Mont Blanc massif average almost 100 a year, with the majority occurring on Mont Blanc itself. There have also been various stunts, some of which the local authorities have called reckless or stupid. In recent years, guards have been placed on the most popular route of ascent to Mont Blanc's summit at peak periods in order to ensure
