Course Overview
This approximately 35 km drive starts from Ddeunbongsaem, the birthplace of the 500-ri Geum River, crosses the Jangsu highland plateau at 500-800 m elevation, and reaches the silver grass plains of Jangansan Mountain (1,237 m). Summer stays cool at this altitude, and autumn brings golden waves of silver grass.
Jangsu is also famous for its premium Korean beef (hanwoo), making this a drive that combines highland scenery with culinary pleasures.
