Mountain park · South Chungcheong, Daejeon
Gyeryongsan
계룡산국립공원
A ridge of jagged peaks and old temples on the edge of Daejeon.
The name means 'rooster dragon mountain', after a ridgeline said to look like a dragon's back with a cockscomb. It was one of the first three parks designated, back in 1968.
Two substantial temples sit on opposite flanks — Donghaksa on the east, Gapsa on the west — and the classic day walk crosses between them over the ridge.
Getting there from Seoul
Door-to-door estimates for a normal day; they stretch on a holiday weekend. Check the timetable before you rely on a last bus back.
Train
KTX to Daejeon, about an hour, then city bus 107 to the Donghaksa entrance. This is the quickest national park day trip from Seoul.
Bus
Express coach to Daejeon or Gongju, roughly 2h.
Car
About two hours. Donghaksa and Gapsa are on opposite sides, so if you cross the ridge you'll need to bus back round to your car.
Wildlife & plants
Animals
Wild boar, roe deer, raccoon dog and marten. The valleys are good for woodpeckers, and flying squirrels are present though rarely seen.
Trees & flowers
Mixed oak and pine with dense fern in the valleys. The stretch of road up to Donghaksa is lined with cherry trees and is a well-known spring drive.
Korea’s wildlife is shy and mostly nocturnal — you’re far more likely to see tracks than animals. Wild boar are the one to know about: keep your distance, don’t run, and never get between a sow and her young.
