Geography

Daejeon lies between latitudes N36°10'59" and N36°30'1" and longitudes E127°14'48" and E127°33'35" near the middle of South Korea. It is 167.3 km (104.0 mi) from Seoul, 294 km (183 mi) from Busan and 169 km (105 mi) from Gwangju.

Known historically as 'big field,' the city lies inside a great circle surrounded by several mountains, with Gyeryongsan National Park straddling the city border on the west, and the foot of the Sobaek Mountain range just beyond the city to the south and east. Three rivers run through the center of the city: Gapcheon (갑천), Yudeungcheon (유등천), and Daejeoncheon (대전천). These flow roughly from south to north, eventually joining the Geum River which borders the city on the northeast. The river changes direction after leaving Daejeon, turning to the southwest and eventually emptying into the Yellow Sea near Gunsan.
