Alta Via 1
Alta Via 1 is a 150-kilometre-long high-level public footpath which runs through the eastern Dolomites in Italy. It is also known as the Dolomite High Route 1. It passes through some of the finest scenery in the Dolomites. The path runs south from Pragser Wildsee, near Toblach, to Belluno. Prags can be accessed by bus, and Belluno has both train and bus services. 

This is the classic high route in the Dolomites, and also the easiest. It gets slightly more difficult as it goes south, but the only section which might present difficulties is the descent from Schiara, and this can be bypassed. About 10–15 days are required to complete the full route. A typical day on the route might involve about seven hours walking, with ascents and descents of about 800 metres. It can be attempted during the period July to September, when the route should be largely free of snow. The route is signposted by dark blue triangles with an inset number one.

Walking the path 

Camping is forbidden along the route, but there is ample accommodation available in mountain refuges and in valley hotels. There are refuges all along the route. During August advance booking is essential. 

The Alta Via 1 passes by several Via Ferrata, but none are incorporated in the route, and no special climbing equipment is required.

The highest point on the route is Monte Lagazuoi at 2,750 metres. There is a large refuge on Monte Lagazuoi which has a restaurant and accommodation for 69 people. The route from Monte Lagazuoi descends to Falzarego Pass and then continues south. There is a cable car from the Refugio Lagazuoi to the Falzarego Pass, but a better way to descend would be through the Via Ferrata Lagazuoi Tunnels. This is a World War I tunnel which runs down through the mountain. It is also possible to descend via the Kaiserjaeger Trail and the Martini Ledge. This route passes a number of relics of the fighting that took place here during World War I. The area around Monte Lagazuoi and 5 Torri is a World War I open-air museum.

There are a number of other high-level routes in the Dolomites, including the Alta Via 2, which runs from Brixen to Feltre.
