The Han River Estuary Protected Area is a critical coastal wetland in South Korea known for its rich biodiversity and vital role as a habitat for migratory birds and aquatic life, offering unique opportunities for nature observation and ecological research.
Located where the Han River meets the Yellow Sea in Gyeonggi-do province, the Han River Estuary Protected Area encompasses expansive tidal flats, marshes, and brackish water habitat that supports a diverse range of flora and fauna. This estuary is internationally recognized as an Important Bird and Biodiversity Area (IBA) and a Ramsar Wetland Site, highlighting its global significance for conservation. The area’s unique geography includes extensive mudflats that sustain rich benthic communities, crucial for migratory shorebirds such as the endangered Saunders's gull, and numerous waterfowl species during winter. Historically, the estuary has long been valued for its fisheries and as a natural flood regulator. It also plays a key role in sustaining local livelihoods through sustainable fishing and eco-tourism. Visitors to the protected area can enjoy birdwatching platforms and guided nature walks, especially during migratory seasons in spring and autumn. The peaceful coastal landscapes provide excellent photographic opportunities, while environmental education programs offer insight into wetland conservation and estuarine ecology. The area's importance is further underscored by ongoing efforts to protect it from urban development, pollution, and habitat degradation, ensuring its preservation as a vital natural refuge in a rapidly developing region. Accessible yet well-protected, the Han River Estuary invites visitors to experience one of South Korea’s premier wetland ecosystems.
