The “Tre Cime di Lavaredo” (Three Peaks of Lavaredo), which are located in the Three Peaks Nature Park, were declared a UNESCO World Heritage Site in 2009. A symbol of the Dolomites, they are three rocky obelisks of great charm that stand out among the other mountains. The ski area includes five connected mountains where there is a variety of gentle and challenging slopes.

The Dolomites are regarded as the most beautiful mountains in the world because of their spectacular vertical walls, peaks that rise to almost 3,500 metres above sea level, deep valleys, a unique pale colour and distinctive sculptural forms. The Dolomites are characterized by carbonate sedimentary rocks, or dolomite rocks. Their geology, which includes plenty of fossil records, gives an insight into marine life in the Triassic period .

The highest point of the Dolomites is the Marmolada, which reaches a height of 3,342 metres, Punta Penia.This is also why the Marmolada, with its pale dolomite limestone rocks is called the “Queen of the Dolomites”. The eastern slope is an impressive sheer wall, a challenge for mountaineers from all over the world, while the northern slope slopes gently, forming a basin that contains the largest glacier in the Dolomites. Thanks to its perennial snow, the mountain has been the protagonist of mountaineering and skiing history.

The most impressive mountains of the Ampezzo Dolomites are the Tofane, three majestic peaks that exceed 3000 meters in height: Tofana di Mezzo (3244 meters), Tofana di Dentro or Tofana Terza (3238 m) and Tofana di Rozes or Roces (3225 m). All three are criss-crossed by numerous paths and equipped routes that offer endless possibilities for walking, via ferratas and climbing of all levels. It is possible to reach the highest peak with a cable car departing from the center of Cortina: this 5 km long cable car deserves the evocative name of "Arrow in the Sky".

The Ledrensi Alps and the Judicaria area have been granted the status of Biosphere Reserves. The pile-dwelling sites of Fiavé and Ledro, in Trentino, are in the list of UNESCO’s World Heritage Sites, together with other ancient pile-dwelling settlements in the Alps. The "Pale Mountains" received one of the most prestigious acknowledgments in the world in 2009, when they were declared a World Heritage Site. This confirmed the universal significance of their geology and their outstanding natural beauty.

The Friulian Dolomites stand out not only for their beauty but also for their suggestive hiking trails, excursions and climbing routes. They are regarded as part of the Natural World Heritage by UNESCO. They belong to the Carnic Pre-Alps and they are situated in the provinces of Udine and Pordenone. Some of the most beautiful valleys in the area are: the Tagliamento valley, the Colvera valley and the Tremontina valley. They are situated in four mountain groups: the Cridola group, the Spalti-Monfalconi group, the Duranno group and the Prammaggiore group. These protected areas are part of the Friulian Dolomites Nature Park and the Forra del Cervina Nature Reserve, which protect the environment of Valcellina.
