Schloss Elmau Luxury Spa Retreat & Cultural Hideaway

The Bavarian Alps resort that holds a Michelin Guide 3 Keys distinction doubles as a working cultural institution, with a concert hall, two libraries, and a ballroom that regularly host jazz, classical music, and author readings. Four separate spas, including an adults-only Badehaus with a rooftop heated pool, handle the relaxation side. The castle exterior promises old-world grandeur; the rooms inside deliver contemporary five-star comfort. Children are welcome at most of it, which either helps or doesn't.
