Contributor Alberto Ardit created this beautiful drone video of some of the most spectacular mountains in Italy. The Dolomites are a subchain of the Alps which extend across portions of the northeastern regions of the country. The tallest peak of the chain is Marmolada, which straddles the Trentino-Alto-Adigio and Veneto autonomous regions. It's height is just over 3.3k meters, just under 11k ft. above sea level. The video covers Marmolada as well as the neighboring Sella and Pordoi Passes.
