Trek Italy’s wild and unspoilt western Alps from the Nufenen Pass on the Swiss border to Ventimiglia on the Mediterranean coast on the Grande Traversata delle Alpi (GTA). This often-overlooked long-distance route covers an epic 809km (503 miles) through the Lepontine, Pennine, Graian, Cottian, and Maritime Alps. Perfect for experienced and fit alpine trekkers, this comprehensive Cicerone guidebook describes the full GTA in 55 stages, each ranging from 7 to 26km (4–16 miles), with a total ascent and descent of over 57,000m. The route is presented in three sections, north, central, and south, enabling flexible planning for those wishing to break the journey into shorter trips, with convenient transport options at each section end. Discover the majestic peaks of Monte Rosa, Rocciamelone, Rocca la Meja, Monviso, and the Argentera spires, and immerse yourself in the wildness of the Italian alpine chain, where chamois skip across scree slopes, ibex clash horns, and ancient sheepdogs still guard flocks against elusive wolves. Each stage is clearly described, with distance, ascent/descent, and estimated walking time, plus details on accommodation and refreshment options to help you plan every day of your GTA adventure. Handy route summary tables, 1:100,000 mapping, and downloadable GPX files for every stage ensure straightforward navigation and itinerary planning, whether you aim for the full two-month journey or wish to complete the GTA in shorter sections. Includes essential advice on preparation, weather and when to go (best walked from early June to late September), transport, mountain safety, local wildlife, history, and what to pack, ensuring you are ready for every aspect of your trek across the Italian Alps. The GTA is suitable for any reasonably fit walker; while the daily ascents and descents are strenuous, no technical skills are required. Public transport options let you tailor your route and avoid less interesting road sections, making the trek accessible to a range of abilities and timeframes. Experience authentic Walser culture, Nebbiolo vineyards, and the slow food movement as you traverse remote landscapes largely untouched by modern tourism. Plan your journey across Italy’s Grande Traversata delle Alpi with the definitive Cicerone guidebook, and discover a classic long-distance trek where every stage brings new alpine vistas, and the spirit of wild exploration guides you from the high Alps to the shores of the Mediterranean.
