Three peaks rising from the river
Along the Namhan River in Danyang, three rock peaks rise from the water at Dodamsambong. Danyang County presents the area as a place to observe karst features and river-shaped landforms. The view is beautiful on its own, but a short geology walk adds another layer: how rock and water shaped the landscape.
Sambong Trail: look closely at the riverside
Danyang Geopark's official walking guide lists Sambong Trail as a 2.0 km route. The mapped area includes the riverside ecological sports park, the old Sambong path, Ihyangjeong and Dodamsambong. Visitors can look for river terraces and limestone features, including the Geumgul cave area. Check the official map and on-site signs for the exact trailhead and any restricted sections.
Seokmun Trail: a gate made by geology
Seokmun Trail is a separate 3.8 km geological route. The Seokmun natural arch is described as a remnant of a collapsed limestone cave; nearby vegetation and river landforms offer other things to notice. The 2.0 km and 3.8 km figures describe separate published routes, not a verified walking time between attractions. Choose a route to suit your energy, weather and the current trail conditions.
Practical information
For Dodamsambong, use the Korean map search name '도담삼봉' and the visitor address 644 Sambong-ro, Maepo-eup, Danyang-gun, Chungcheongbuk-do. Danyang Tourism Corporation lists standard parking fees of KRW 3,000 for a small car and KRW 6,000 for a large vehicle at the Dodamsambong car parks. The car park itself is registered at 83-3 Hagoeri, Maepo-eup; that is not the same as the attraction's visitor address. Boat rides and Sambong Story Hall have separate operating arrangements.
Current trail access, walking times, slopes, weather-related restrictions, facility hours and transit schedules have not been independently confirmed. Check official updates before setting out, especially after rain or snow.
