Seoraksan National Park

Seoraksan is South Korea's oldest national park, established in 1970, and the one most Koreans name when asked to describe the country's most dramatic mountain landscape. Its 163.6 square kilometres contain a concentration of geological, botanical and cultural diversity that is unusual for a park of its size.

The park is divided into Inner (Naebu) and Outer (Oebu) Seoraksan. Outer Seoraksan is where most visitors go, with its trail network, waterfall views and the park's most photographed structure — a painted wooden footbridge spanning a turbulent mountain stream in a valley of granite boulders.

What makes Seoraksan botanically remarkable is its position at a biogeographic crossroads: warm-temperate species from the southern Korean peninsula meet boreal species from the north, creating a diversity of plant life in a relatively small area that is unusual at this latitude.

The granite peaks of the outer park are the most visually memorable aspect of the landscape — pale grey rock faces rising abruptly from forested slopes, the result of ancient volcanic activity and subsequent glacial sculpting over tens of millions of years.

Autumn is when Seoraksan reaches its most famous visual register: the maple and oak slopes turn through yellow, orange and deep red in sequence, creating the phenomenon known in Korean as koong-chae-wool-yeom — the valleys of heaven and earth. Photographs from this season are what most foreign visitors have seen before arriving.

Summer transforms the park differently — the monsoon season brings heavy rain that swells every stream and waterfall into rushing white water, sometimes closing trails and creating an entirely different kind of landscape intensity. The summer green is lush but the conditions are demanding.

Winter closes the higher trails entirely but brings a different kind of visitor: those who come for the snow-covered ridgelines and the way the frozen streams and frost-covered trees give the granite landscape a stripped-back severity. Daecheongbong at 1,708 metres becomes a serious winter mountaineering objective.

Two Buddhist temples — Baekdamsa and Sinheungsa — sit within the park, their weathered stone walls and forested settings offering a quiet counterpoint to the park's more dramatic natural scenery. Sinheungsa's position at the valley floor, backed by a granite cliff, is particularly striking.

The park's cultural depth adds another layer to the natural landscape. Baekdamsa Temple, deep in the inner valley, requires a longer hike to reach but offers one of the most secluded temple settings in any Korean national park — the approach through a narrow valley with granite walls on either side feels like entering a space set apart from the ordinary world. Sinheungsa at the valley entrance is more accessible and is notable for its position beneath a granite cliff face: the temple's weathered wooden buildings and stone lanterns are set against a backdrop of pale grey rock that changes colour through the day as light rakes across it. The combination of ancient tree cover, tumbling streams and the constant sound of moving water makes the entrance area of Outer Seoraksan one of the most immediately calming natural environments in Korea. In autumn, the area around Sinheungsa fills with photographers attempting to capture the temple framed by the famous Seoraksan maples — the resulting images are among the most reproduced in Korean visual culture, and arriving early in the morning before the crowds allows a glimpse of the scene without its usual gathering of tripods.

Seoraksan is South Korea's oldest national park (1970) and its most scenically dramatic, with granite peaks, glacial valleys, and one of the most diverse plant ecosystems in East Asia at this latitude.

The park is a UNESCO biosphere reserve (1982) and a Korean government World Heritage tentative list candidate, confirming its international scientific significance.

The iconic painted footbridge, waterfalls, and autumn foliage make it one of the most photographed natural landscapes in Korea.
