I didn’t really do this site justice; my experience was limited to one group of tombs at Seollung in the south of Seoul. These are by far the most accessible being just a short walk from the Metro station with the same name.
It was an enjoyable park to wander around for a little while and you were able to climb up and get a close up view of two of the three tombs within the site. I was surprised to see how large the statues guarding the burial mounds were, and I must admit to being quite impressed. The park now also contains a small museum with information about the tombs which are spread out across Seoul and its environs. A slight frustration came from not being able to get a closer look at King Jungjong’s tomb, from the base of the mound there isn’t really a huge amount you can see. It seems that this is a bit of a frustration at many of the tombs, and I am sure there are legitimate reasons for it but it does make the visiting experience a little limited.
If I had been in Seoul for a little longer then I am pretty sure I would have visited more of these sites, but the draw of the city’s other delights kept me busy.
