Next to/Around the ever so fancy Yeonginsan Natural Forest are plenty of hiking trails and views. This one, on the edge of the park has trail access from inside the park and outside so it can either be an all day event or a 30 minute, hearty hike. Just depends on what you are looking for.
The trails aren't easily routed on Naver, but the long hike begins in the lower parking lot below Yeonginsan Natural Forest. There is a trail that follows the road and another that goes up the ridge to the peak. This is the one we recommend. Although on this day we cheated and just walked the ridge. It was still a workout.
Don't be like us. Be certain to take water with you even if you are taking the easy route. The hike is surprisingly intense right at the end and you are fully exposed at to the sun at the point. You are GOING to want water.
