In 2003 Messner started work on a project for a mountaineering museum. On 11 June 2006, the Messner Mountain Museum (MMM) opened, a museum that unites within one museum the stories of the growth and decline of mountains, culture in the Himalayan region and the history of South Tyrol.
The MMM consists of five locations: MMM Firmian at Sigmundskron Castle near Bozen is the centerpiece of the museum and concentrates on man's relationship with the mountains. MMM Juval at Juval Castle in the Burggrafenamt in Vinschgau is dedicated to the "magic of the mountains", with an emphasis on mystical mountains, such as Mount Kailash or Ayers Rock and their religious significance. MMM Juval houses several art collections. MMM Dolomites, known as the Museum in the Clouds, is located at Monte Rite (2181 m) between Pieve di Cadore and Cortina d'Ampezzo. Housed in an old fort, this museum is dedicated to the subject of rocks, particularly in the Dolomites, with exhibits focusing on the history of the formation of the Dolomites. MMM Ortles at Sulden on the Ortler is dedicated to the theme of ice. This underground structure is situated at 1900 metres and focuses on the history of mountaineering on ice and the great glaciers of the world. MMM Ripa at Brunico Castle in South Tyrol is dedicated to the mountain peoples from Asia, Africa, South America and Europe, with emphasis on their cultures, religions, and tourism activities. MMM Corones, opened in July 2015 on the top of the Kronplatz mountain (Plan de Corones in Italian), is dedicated to traditional climbing.

Alta Badia is a ski resort in the Dolomites of northern Italy, in the upper part of the Val Badia (German: Hochabtei) in South Tyrol. It is included in the territories of the municipalities of Corvara, Badia, and La Val. Centered on Corvara, the extended area's lift-served summit elevation is 2,550 m (8,366 ft) on the Sella group, with an overall vertical drop of 1,226 m (4,022 ft) to Pedraces. Alta Badia is a regular stop on the World Cup schedule, usually by the men in mid-December. Its giant slalom course, the classic Gran Risa, is one of the most challenging on the circuit. Nearby World Cup venues are Val Gardena to the west (over Gardena Pass) and Cortina d'Ampezzo (over Valparola Pass) to the east.
