Erupting above the immense plains of Dakota and Wyoming, the Black Hills are a grandiose concentrate of nature, strewn with caves, canyons, lakes and prairies where bison graze, as in Custer State Park... The hills are steeped in history, first as the tribal land of the Sioux Native-Americans, then as a settling land for German and Scandinavian pioneers; without forgetting the iconic Mount Rushmore. Home to a host of marvels, it is well worth spending time here.
