Originally built at the turn of the century as a palace for star violinist Mary Portman, this out-of-the-way jewel in the Alps makes for a perfect stopover on the way to or out of the city. Now a wellness hotel, the arts-and-craft style building has added an all-inclusive spa with outdoor pool. Kin Ludwig II's home in Schachen is also only a three-hour hike away. Packages start at 600 Euro per person for a double room.
