Yongyeon Valley is a 6 km-long valley located at San 1-0, Sagimak-ri, Sacheon-myeon, Gangneung-si, Gangwon State. The valley and its surrounding area are collectively designated as a nationally recognized geological heritage site. The valley follows the Sacheoncheon Stream flowing between Ungyebong Peak (530 m above sea level) and Cheonmabong Peak (1,015 m above sea level). The pools within the valley are called “Yongso (Dragon Pool)” due to a legend that a dragon once lived here and ascended to the heavens. The area features diverse fluvial landforms, offering significant geological and geomorphological value. It is also historically important, with nearby Buddhist ceremonies held at Yongyeonsa Temple and traditional ancestral rites performed at Yongso.

In addition to its clear flowing waters, Yongyeon Valley features Sagimak Reservoir. Further inside lies Yongyeonsa Temple, a temple established during the Silla Dynasty. The creation of the reservoir led to the disappearance of Yongyeon-dong Village. Above and below the reservoir, water flows through uniquely shaped rocks and wide flat bedrock, harmonizing with pine trees to create picturesque scenery that has long attracted visitors. During the summer, many vacationers gather on the wide rock surfaces below the reservoir to relax. On a tall rock nearby, the inscription “Gangneung Choi Clan Yongyeon Sejang-dong” is engraved.

From Yongyeon Valley, you can easily reach one of Gangneung’s famous attractions, Daegwallyeong Sheep Farm, by car in about 30 minutes. On the way, stopping by Daegwallyeong Museum allows visitors to learn more about the region, enhancing the experience of the scenic Daegwallyeong area. After visiting the museum, you may also enjoy forest bathing at Daegwallyeong National Recreational Forest. Nearby, the Daegwallyeong Sheep Farm offers expansive grasslands and grazing sheep, providing a relaxing atmosphere. For those who enjoy more active tourism, skiing is available at Alpensia Resort and Yongpyong Resort.
