Pack your walking gear and get ready for one of the most sensational treks in the world. Alta Via 1 is a 12-stage trek across the foothills of the Eastern Dolomites. Each day-long stage takes you through a series of stop-overs and winds up at a mountain refuge where you can rest for the night. The site is a veritable treasure-trove of information, with short descriptions of each stage, maps, details on wildlife in the area, weather forecasts and clothing advice. Warning: once you visit this site, you'll want to head for the hills.
