Since 1983 this 13th-century castle in the hills above the hamlet of Stava has been the home of the south Tirolese climber and polar adventurer Reinhold Messner—the first climber to conquer Everest solo. Part of the castle has been turned into one of five in Messner's chain of Dolomite museums, where guided tours (Italian and German only) are required to view his collection of Tibetan art and masks from around the world. It's a five-minute shuttle ride from Naturno (there's no parking at the castle), or an hour hike on many local trails. The walk from where the shuttle lets off to the castle is steep and about 3/4 mile. It's paved, but can be a difficult walk.
