Cheongju Sangdang Mountain Fortress - The majestic gate is perfect for photos.

Taking the bus to Sangdang Mountain Fortress, you need to climb a small slope to reach it. From a distance, you can see the South Gate, which is also a popular filming location for many movies. The entire mountain fortress is very large, and the pavilions and gates are brightly colored. I recommend taking photos from the gate's entrance for stunning pictures. Many people also come here for hiking. We only visited the gate and then left, but if you have time, you should explore the entire area. It looks quite vast!
