Hiking in the Mountains of Italy can be very tiring at times and many times you are above 2000 meters, experience, good equipment, sure footing, absence of vertigo and good physical condition are indispensable to ensure safety.
Often dangers are undervalued in the mountains: a rapid change in weather, an unexpected storm, a premature snowfall, an icy patch of ground, and fast-moving rivers all can turn a pleasant, light-hearted trip into a ordeal, even on well-marked stretches of path. Good self control is perhaps one of your most valuable skill sets.
A fundamental condition for trekking along the High Altitude Trail paths is good weather! Therefore you should find out weather conditions first from the available sources. If, despite all the above precautions and excellent equipment, an accident nevertheless happens (a slip, twist, fracture, injury from falling rocks, lightning, illness, vertigo etc.), try not to panic (difficult though this is) and follow the recommended indications where possible.
The CNSAS (National Speleological Mountain Rescue Organization, a special section of the CAI, Italian Alpine Club, whose emergency telephone number is 118, active 24 hours) and the Austrian Mountain Rescue normally operate in so-called hostile environments and in all inaccessible areas of the province. This does not only mean, areas such as, cliff faces or vie ferrate (equipped paths), but also above all snowfields and glaciers, ice falls, avalanches, cable cars, ski slopes, caves, ravines, gorges and gullies, rivers and all other types of environment not necessarily at high altitude (hills, woods, etc.), that due to access or movement problems, or in special weather conditions, require the intervention of qualified personnel that have expertise in all areas of mountaineering and speleology techniques and rescue.
Keep in mind that the refuges located along the mountain trails are equipped with public telephones (except the fixed bivouacs); in addition, all refuge managers are trained to help send correct and quick requests to Mountain Rescue.
