Nari Basin

Nari Basin is a crater basin formed when the caldera collapsed after viscous trachyte, andesite, and tuff erupted in volcanic activity at the end of the Tertiary period of the Cenozoic Era. In the past, people who lacked food dug up and ate the roots of the Ulleungdo lily (seommal-nari), which gave rise to the place name 'Nari', and the basin came to be called Nari Basin after it.
It measures 1.5 km east to west, 2 km north to south, with an area of 1.5∼2.0 ㎢. Around the Nari Basin, mountains about 500 m above sea level surround it like a screen; the highest is Seonginbong (984 m) in the south, and inside the basin lies the cone-shaped central crater Al-bong (611 m). The Nari Basin was formed when the crater north of Seonginbong collapsed during a volcanic eruption and is about the size of 28 football fields. Thanks to its unique volcanic topography it was registered as a national geopark, and walking and trekking routes have been created around the basin. The most recommended routes are those around Al-bong at 538 m and Kitdaebong at 579 m. As an island area, it has plants native only to Ulleungdo, such as the Ulleung chrysanthemum, so visitors can walk while enjoying a unique forest scenery not found on the mainland.
