Wonsusan Wetland Eco Garden

Character

Wonsusan Wetland Eco Garden occupies a former rice paddy in a valley on Wonsusan’s lower slope, where a 20,000-square-metre restoration created aquatic planting beds, drier wetland areas and small ponds as an ecological classroom inside central Sejong

The project used the shape of the abandoned field rather than flattening it into a conventional park. Artificial structures were deliberately limited, while 26 species of aquatic and flowering plants — about 100,000 plants in total at opening — were introduced across several wetland conditions

That gives the garden a different scale from the mountain trails around it. The landscape is read at close range: shallow water, planted margins and small habitat changes occupy the foreground, while Wonsusan’s forested slope remains around them

The experience

Gentle approaches and deck paths make the wetland easier to move through than the nearby summit routes. Rest areas break up the short circuit, and the garden can function as a compact visit even without continuing farther into Wonsusan

The wetland types sit close enough together for their differences to be visible without a long hike. Aquatic planting beds hold wetter ground, drier wetland sections sit above them, and small ponds add another layer of open water. The layout was intended for observation and environmental education, especially for children

The surrounding Wonsusan facilities broaden that family use. An adventure playground was added nearby later in 2016 after resident feedback, placing more active play beside the quieter wetland and forest paths

History

The site began as an unused rice paddy in a valley below Wonsusan. During Sejong’s early development, the Happy City Construction Agency and LH turned the field into a wetland garden while retaining the existing valley form and minimizing new hard structures

Wonsusan Wetland Eco Garden opened to the public on August 31, 2016, establishing aquatic wetland, drier wetland and small-pond habitats across the valley

Later that year, additional family facilities were introduced around the Wonsusan recreational area, including an adventure playground developed after local residents asked for more places where children could play in the forest. The wetland itself remained the quieter ecological part of that larger network

Before you go

The garden sits within the wider Wonsusan landscape but does not require a mountain hike. Its compact scale suits a short standalone stop, while the surrounding paths allow the visit to continue into the forest and the larger Wonsusan trail system
