Located in the Seogwipo area of Jeju Island, Soesokkak Estuary (쇠소깍) was originally called ‘Soedun’, which means a lying down ox, and it was only later that it became more widely known as ‘Soesokkak’. This is the mouth of the Hyodoncheon stream. As the fresh water meets the ocean, it broadens into wide slow flowing river. ‘Soe; means an ox, ‘so’ means a ‘pool of water’ and ‘Kkak means ‘the end’. Soesokkak Estuary is lined with cliffs of curious lava formations, which are overhung with pine trees. Here the water takes on the deep blue of the ocean, and the scenery is very picturesque. Soesokkak is also well-known for its small, flat wooden boats called “Teu” that have been used for hundreds of years to ferry people across the estuary. The boat is pulled across the estuary by a long rope that is strung between the two banks. Taking a leisurely ride on a Teu across the clear water of the estuary is a great way to enjoy the area’s magnificent scenery.Soesokkak Estuary is located in Hahyo-dong on the Southern side of Hallasan Mountain. The area is also well-known for its tangerines, and visitors are drawn to the area by the fresh scent of the fruit.
