Nakdonggang Estuary

Natural sand island where the river harmonizes with the sea

As the modern delta formed by Nakdonggang River meeting the South Sea, the attractions including sand bars, sand dunes and lagoons created by sand piles are the highlight of natural beauty.
A variety of plants and animals inhabit the wetland and Bird Sanctuary and a geotrail course leads from the Eco Center to Amisan Observatory


This is where the Nakdong River meets the Southern sea to create the largest modern estuary in Korea. Discover beautiful sights of barrier islands, dunes, and lagoons with migratory birds passing by.

Name and history

Nakdonggang River, the longest river in South Korea(basin area 23.384㎢, river length 510.36㎞), originates from Hwangji Pond in Hambaeksan Mountain, Taebaek, Gangwon-do, and flows through Gyeongsangbuk-do, Daegu Metropolitan City and Gyeongsangnam-do areas, dividing into two waterways at Daejeo-dong, Nam-gu, Busan, before reaching the South Sea.
Nakdonggang Estuary is a transitional area between the sea and river, located where Nakdonggang River begins to flow into the South Sea, with deltas formed around the estuary, which invigorated various agricultural and fishing activities from the past. With islands, sand bars and mudflats, it was a world-class bird sanctuary that attracted numerous species of migratory bird.
For Eulsukdo, the center for arriving migratory birds, located at Nakdonggang Estuary, there are two uncertain stories about the origin of its name: it might have been from “Eulsuk” which means wonderful in Chinese or from “island with clean water where numerous birds live”
In Eulsukdo, once the center for arriving migratory birds, construction of a landfill and sewage treatment plant and growth of onion patches resulted in more visitors and subsequent reduction of migratory birdlife, accelerating destruction of the ecosystem. However, due to Busan City’s Eulsukdo restoration project, the number of migratory birds is increasing again.

Representative vegetation

Argusia sibirica

Argusia sibirica is a herbaceous perennial similar to gromwell. It was named such because it grows from sandy ground. Clusters of several white flowers bloom in mid-summer, presenting pure beauty.

Asiatic sand sedge

As a plant of the sedge family growing on the seaside sandy ground, Asiatic sand sedge holds sand on the seashore, preventing loss and helping sand bar development. Asiatic sand sedge produces large fruits and black seeds which fall in September and are scattered on the sandy ground.


Reeds, a perennial herb belonging to the grass family, grow in colonies on the sand ground of wetlands, lakes and seashores. As an aquatic herb with part of the stems and roots under water, only the upper part of the stems reaches above the water. Reed stems are used to make blinds and brooms.

Scirpus planiculmis

Scirpus planiculmis, a perennial herb belonging to the Cyperaceae genus, grows in wetlands and tidal flats. At Nakdonggang Estuary, it grows in a wide range of colonies on a tidal flat, and the tubers produced in the winter are feeds for migratory birds such as swans.

Geological features of Nakdonggang Estuary

Around Nakdonggang Estuary, extensive mud flats accompany small and large sandy banks (offshore bar) exposed above the water, and formed by sand or pebble piles. As a brackish water area where sea water mixes with fresh water, the estuary is rich in biodiversity and home to an annual influx of migratory birds

Because it is cool in the summer and warm in the winter, it is suitable for birds laying eggs and multiplying with riverside sand and reeds, a paradise for the 130,000 migratory birds of 167 species that visit there.

Further, at Nakdonggang Estuary, there are sandy banks called Daemadeung, Maenggeummeorideung, Jangjado, Sinjado, Baekhapdeung, Doyodeung and Jinudo. Having sprung to life, the terrain is rapidly changing every year with deposits continuously flowing in from Nakdonggang River being displaced by the tide, piled up and dispersed repeatedly.

Explore Nakdonggang Estuary geotrails, exhibition halls of the Eco Center and Amisan Observatory and feel the vibrant “Earth” with understanding of geological features, topography and ecology of the Nakdonggang River that is full of life.
