Saseondae Tourist Resort was established around Saseondae located on the bank of Owoncheon Stream in the upper region of Seomjingang River. The name Saseondae originates from a legend of four immortals and fairies. The legend has it that two immortals of Maisan Mountain in Jinan and two immortals of Unsusan Mountain in Imsil gathered by Owoncheon Stream to enjoy the beautiful nature. Looking down at the immortals were four fairies, who fascinated by the picturesque scenery of the region, came down from the sky to join the hermits. Since then, the place has been called Saseondae and the stream Owoncheon. Unique rock formations, woods and clear water surrounding Saseondae create a magnificent harmony. The Unseojeong Pavilion (Regional Tangible Cultural Asset No. 135) situated in the dense forest of Saseondae also adds beauty to the scenery. Furthermore, visitors to Saseondae may also enjoy the handcrafted works of noted sculptors from the nearby art village in Ogung on display at Saseondae Sculpture Park.
