What is "gwanggyosan"

Gwanggyosan (582 m) is a small mountain in Gyeonggi Province, South Korea. It lies on the border of Suwon and Yongin, though the wider range extends north and so also borders Uiwang, Gwacheon, Seoul and Seongnam.

The summit offers views across Suwon, Yongin and Bundang. The mountain is commonly hiked from Gwanggyo Reservoir in Suwon.
