Taeha-ri is a fishing village located along the western coast of Ulleung-do. Hakpo harbor lies to southwest of the village. After the settlement policy (19th year of King Gojong’s reign, 1882) of Ulleungdo was proclaimed, people who moved to the area referred it as ‘Big Hwangtogumi’, or Big Red-clay Cave, after they spotted holes where red clay were dug out on the coast. Later, the name was changed to ‘Daeha’ and finally to ‘Taeha’, both in Chinese characters. Taeha Seaside Walkway starts after you pass Hwangtogumi at the entrance and climb up a spiral staircase. The walkway is 400 m long along the coast. Once you follow the walkway and the trail for about 1 km, you will arrive at Taeha lighthouse and Taeha observation deck. Rocks around the walkway are composed of trachyte and trachytic agglomerate. The walkway features beautiful and picturesque views, resulted from wind and wave erosions. Tafoni, honeycomb weathering in granular rock, are found in the surrounding rocks. Tafoni in basaltic trachyte are resulted from wind erosion and salt weathering, in which salts on the surface of rocks widen pits or dissolve the grains of rock apart. Along the walkway, there are ‘Hawk Rock’ which resembles the head of a hawk and “Gajegul Cave’ (‘Sea Lion Cave’ in the Ulleungdo dialect), formed by erosion. It is very likely that there were sea lions in Ulleungdo in the past. Daepoonggam cliff features well-developed columnar-joints. It is known for Chinese Juniper (Juniperus chinensis) that grows at the summit of the rocky cliff on very little amount of soil. Because the tree has grown under rare conditions for a long period of time and created an unique ecological environment, ‘Natural Habitat of Chinese Junipers in Daepoonggam’ has been designated and protected as Natural Monument (no. 49).
