Chuam Suspension Bridge

A slender pillar of rock rising from the sea among smaller rock formations, at the southern edge of the city. The sunrise behind it appears at the start of the national anthem on Korean television, and it is a popular place to watch the sun come up. In the Joseon era the official Han Myeong-hoe was so taken with this stretch of coast that he named it Neungpadae. A 72-m suspension bridge over the sea, opened in 2019, gives another view of the rocks; it closes in bad weather. The path to the rock itself is not suitable for wheelchairs.

A less popular but more picturesque beach a few km south of town.

There is a 2.2km sea path, so you can walk while looking at the sea. There is also a photo zone where you can take pictures in the Hanseom Light Tunnel.

A limestone cave in the middle of downtown, found in 1991 during construction work. About 700 m of its 1.4 km length is open to visitors, with stalactites, curtain-shaped formations and a flowstone "waterfall", and it stays at 14–15°C all year. In 2005 an endangered golden bat (red bat) was found living inside. Last entry is at 17:30, and the cave is not suitable for wheelchairs. On the hill above, a nature park has a boardwalk around sinkholes formed by the same limestone.
