Where only an eagle's nest should be, a quartet of hotels—dating from 1873, 1904, 1991, and 2007—take luxury to new heights, literally. Perched 1,600 feet over Lake Luzern, this complex was masterminded by the Frey family, who are famous for turning it into a celebrity hotspot in the 1950s. At this writing, the entire compound is undergoing massive renovation, with one hotel opening after another: the first in 2011, the last by 2014. Once done, the resort will include
some 500 rooms, a "medical wellness" sanatorium, a residence hotel, a conference center, and a full-service spa with massage therapy, milk baths, sulfur baths, and plain old outdoor hot tubs. This isn't the first bit of updating to be carried out: in the 1990s, hillsides were blasted out to accommodate pools and a stunning golf course. Long host to kings, queens, and celebs like Walt Disney and Charlie Chaplin, the resort still welcomes VIPs (who often arrive on the helipad). Guest rooms are all being completely modernized as the fin de siècle splendor is slowly refurbished: 19th-century frescoes, Art Nouveau wickerwork chairs, stained-glass windows, and the 14th-century late-Gothic chapel are all getting a facelift. Bring along your hiking boots, as the resort has a restaurant perched on top of the nearby Hammetschwand Peak, along with one down by the lake. The food is nouvelle and slimming but, of course, your wallet will need to be fat.
