Cheonggyesan Mountain surrounds Seoul Grand Park, SeoulLand and National Museum of Modern and Contemporary Art, Gwacheon. The mountain boarders the area of Yangjae-dong, Seoul and Gwacheon-si, Seongnam-si, and Uiwang-si, Gyeonggi-do. The mountain is nestled at the foot of Gwanaksan Mountain, south of downtown Gwacheon. Dense forests, neat valleys, parks, and temples are available in the mountain, making it a suitable climbing course for families. Also, varied walking courses are set up. The top of the mountain, Manggyeongdae, is not open to public access as a government facility is situated on the peak. Guksabong Peak (alt. 538m) and another peak (alt. 545m) are connected through a mountain path.It is said that a faithful person, Joyun in the late Goryeo period entered Cheonggyesan Mountain from Songdo after the demolition of Goryeo by Yi Seong-gye who was the first King of the Joseon Dynasty. Also, it was referred to as “Cheongryongsan” because the area is regarded as the place where a blue dragon (Cheongryong; 청룡) ascended to heaven. Based on the principles of geomancy, Gwaksan Mountain and Cheonggyesan Mountain are called “Baekho” (White Tiger) and “Cheongryong,” respectively.
