Pros:
It is right off the #2 (green) Seoul subway line at the Sports Complex station. just walk to the gymnasium where the basketball games are held . The course starts around the perimeter of the building.
Cons:
I only found 3 baskets are they were all the holes were close enough to jump put. From the looks of it, this course might be seasonal. I saw a roped off section of land that had tee signs, but there weren't any baskets in the ground.
Other Thoughts:
I still made an 18 hole outing from these 3 baskets though. This is definitely a one putter course. The Koreans rarely provide any information about course statuses and when they do it's usually in Korean. It's worth noting that you could probably make your own safari course in the park across the main street, but not in the summer because of the increase in park goers and filling out of the trees.
