Bamseom, River island in Han River, Seoul, South Korea
Bamseom is a pair of sandy islets in the Han River between Yeouido and the north bank, stretching over a kilometer with distinct zones of vegetation. The islands host diverse plant communities including grasses, willows, and species adapted to wet soils.
Until 1968 the islands supported settled communities before being demolished for urban development projects. This transformation marked a shift from inhabited space to protected ecological site.
The name comes from the Joseon period and refers to the island's appearance in local tradition. Today it draws birdwatchers and nature enthusiasts who gather to observe migratory species that stop here during winter months.
Six observation platforms positioned around the perimeter provide viewing points for birdwatching and studying wetland ecosystems, especially during winter. Early morning visits offer the best chance to observe active wildlife.
Since its demolition more than 50 years ago, natural sediment deposition has dramatically enlarged the islands through continuous accretion. This growth demonstrates how riverine landscapes naturally rebuild themselves over time.
