At the foot of Austria’s Wilder Kaiser mountains, Stanglwirt has become one of Europe’s most successful tennis camps, run by Peter Burwash International (PBI) since 1978. The 175-room resort and spa boasts 14 tennis courts, six of them indoors, allowing year-round play. Its stunning location, just an hour and a half from Munich and an hour from Salzburg, attracts a diverse international following. Though the camp offers just two hours of group lessons daily, the breathtaking mountain backdrop and well-maintained red-clay courts make it a unique tennis destination.
