 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.
