A volcanic hill with water at its heart
Some of Jeju Island's volcanic hills, known as oreum, shelter wetlands in their summit craters. Mulyeongari Oreum in Namwon, Seogwipo, is one of them. As Visit Jeju explains, the word “mul,” or water, points to this remarkable high-altitude wetland. Beyond the open pasture and forest, this is another way to discover the island's volcanic landscape.
What old pastoral stone walls tell us
The landscape on the approach reflects Jeju's livestock-raising history. Jatseong are traditional stone walls built to mark grazing boundaries. Cedar trees and stairways take over as the path enters the woodland. Rather than racing straight for a summit view, pay attention to the shift from grassland to forest and to the human traces in the landscape.
The important access restriction: perimeter trail only
Older photographs and travel stories can give the impression that visitors may freely enter the crater wetland. The current official Visit Jeju attraction page, however, expressly says only the perimeter walking trail is available, with an estimated walking time of about 1 hour 40 minutes. Plan around the permitted circuit. Do not enter the protected wetland basin or closed routes. Historic descriptions and present-day access rules are not interchangeable.
Before setting out
The official address is 6101 Jungsangan-dong-ro, Namwon-eup, Seogwipo-si, Jeju (제주특별자치도 서귀포시 남원읍 중산간동로 6101). Mountain addresses on Jeju do not always pinpoint the correct car park or trail entrance. Confirm the open route, parking approach, weather restrictions and any temporary closures with Jeju Tourism Information Centre on 064-740-6000 before travel. We could not verify fixed daily opening hours or admission fees from these references. Wooden steps can be slippery in rain or mist.
You do not have to step inside a protected crater to appreciate it. Walking around the wetland while respecting its boundaries is part of what makes this Jeju experience distinctive.
