(Please verify the exact route using a map app)

Course Overview

Chungnam's west coast features multiple seawalls built from large-scale land reclamation projects. This course starts at Sapgyoho Seawall, passes through Ganwolho Seawall, and continues through the Cheonsuman Bay area.

Driving atop the seawalls presents a unique contrast between ocean on one side and farmland on the other. During autumn harvest, golden rice paddies against the sea create a spectacular scene.

Section Highlights

Section 1: Sapgyoho Seawall (approx. 15 km)

A straight road connecting Dangjin to Seosan, with open vistas on both sides.

Section 2: Ganwolho Seawall (approx. 20 km)

Drive between Ganwolho Lake and Cheonsuman Bay. Detour to Ganwoldo for Ganwolam Temple.

Section 3: Cheonsuman to Taean (approx. 20 km)

Pass through Cheonsuman tidal flat areas toward Taean. Winter brings migratory birds for birdwatching.

Driving Tips

  • Strong winds on seawalls — smaller vehicles take care
  • Speed limit mostly 80 km/h with speed cameras
  • Check tide tables when visiting Ganwolam Temple
  • Autumn harvest (October) offers the most beautiful contrast of paddies and sea
