Gangmun Sotdae Bridge, located at Gangmun Beach in Gangneung, serves as the dividing point between Gangmun Beach and Gyeongpo Beach. The sotdae is said to have originated from a tall pole with a pouch containing rice seeds hung high, symbolizing prayers for a bountiful harvest. It was also used in rituals wishing for abundance, and as a symbol of folk belief, often with a carved wooden bird placed at the top of the pole.

In Gangneung, this sotdae was traditionally called Jinttobaegi. In Gangmun, ritual ceremonies known as Seonangje are held three times a year—on the 15th day of the first lunar month, the fourth lunar month, and the eighth lunar month. It is believed that Jinttobaegi assists the village guardian deity, protects against the three disasters (flood, fire, and wind), and brings peace, abundant fishing, and a rich harvest to the village.

Looking at the structure rising from the water beneath Gangmun Sotdae Bridge, you will see three birds facing different directions; visitors often make wishes here. Toward Gangmun Beach, you can spot a structure resembling an observatory. Crossing the bridge leads you to Gyeongpo Beach.

As you walk along, you will also notice the nearby Seamarq Hotel, known for its excellent views. Through the trees, a triangular tiled-roof house can be seen—this is said to be the shrine where the Seonangje ritual is held. On the opposite side of the shrine, the water flows calmly like a quiet bay or lake. When viewed on a map, seawater appears to be enclosed between two bridges, forming a lake-like landscape.

At the corner where Gangmun Beach begins, there is a well-known restaurant in Gangneung called “Paul & Mary,” famous for its handmade burgers. Since there are often many customers waiting in line, it is recommended to visit early.

Additionally, along Gangmun Beach, there are several frame-shaped photo zones where visitors can take pictures, making it a great place to capture memories. Especially when seen up close, the scenery of Gangmun Sotdae Bridge offers an exotic atmosphere that is rare to find in Korea. Despite its strong local identity reflected in the name Jinttobaegi, the bridge also features structures reminiscent of European-style sculptures, making it a destination worth visiting at least once.
