The third-largest of Germany’s 16 provinces both in terms of size and population, Baden-Wurttemberg in the country’s southwest borders both France and Switzerland and is home to the Black Forest, Heidelberg, Mannheim and Stuttgart. In many areas, residents speak Swabian (Schwäbisch) or Badisch, dialects so strong that speakers of standard German can find them difficult to understand. With over 40 million annual overnight stays, Baden-Wurttemberg is second only to Bavaria in terms of visitors.
