The arboretum occupies 103,386 square meters of land reclaimed from a former agricultural reservoir.
It is specifically designed to function as an 'eco-island' within the surrounding industrial and residential zones of Guro.
The arboretum's collection includes a dedicated 'Forest Education Center' that promotes native plant propagation.
The Hang-dong Railway line passing through the site was historically used by local chemical factories but is now a popular walking trail.
The park maintains a specialized 'Seed Bank' to preserve indigenous plant species from the Korean peninsula.
Pureun Arboretum is Seoul's first municipal arboretum, established as an eco-friendly space on the site of a former reservoir. The park features over 2,000 species of native and introduced plants organized into 25 distinct themed gardens. It integrates the Hang-dong Railway, a defunct track that cuts through the landscape, offering a juxtaposition of industrial history and natural preservation. The central reservoir, formerly used for agricultural irrigation, now serves as a wetland habitat for waterfowl and aquatic vegetation. Its design emphasizes sustainable forest management and biodiversity education within the Guro urban district. Visitors can traverse extensive boardwalks that hover above the marshy areas, providing views of the flora without disturbing the ecosystem.
The old railway tracks framed by the lush foliage and the wooden bridge overlooking the central reservoir.
Bring insect repellent during warmer months, especially when walking near the reservoir boardwalks.
Follow the old railway tracks to connect with the nearby walking trails that extend beyond the arboretum perimeter.
Visit the visitor center first to obtain a printed map of the 25 specific themed gardens to avoid missing remote sections.
Do not attempt to walk along the active railway sections outside the designated park area; avoid visiting during peak summer afternoons due to limited shade.
Closed on certain public holidays and occasionally on Mondays for maintenance.
Stay on marked paths to protect sensitive wetland flora; do not pick plants or disturb the wildlife.
