About Seonginbong
Seonginbong is the highest point of Ulleungdo, the volcanic island in the East Sea, and the source of all its streams. Valleys radiate from the summit to the coast.
North of the peak lies the Nari basin, a caldera about 1.5 km by 2 km and the largest flat land on the island, with Albong, a central cone, rising inside it — a double volcano. It is the snowiest place in Korea.
The usual climb starts near Dodong, crosses the summit and drops to Albong and the Nari basin.
