How To Get There: From Songnae Station of Seoul Line 1, take Bus#16 to Grand Park's main gate.
For the first part of our trip here, we went with my wife's co-teacher, Julie and here kids for a picnic.
My wife and I came back to this park later on mainly to do some hiking to Mt. Gwanmosan (160m/525'). It is just a small mountain but the view of the surrounding is pretty nice. A much needed cool breeze from the top is also a must have when visiting the park on a very hot and humid day.
