This luxury hotel houses not only multiple restaurants, spas and golf courses but also Olympic-standard sports facilities - and a high-spec clinic boasting 80 medical staff, who offer guests everything from sleep therapy to dietary advice and surgery. Grand Resort Bad Ragaz lies in the shadow of an ancient gorge, the thermal waters of which have lured visitors for centuries.
