Given the height and proximity to the city, I imagine this is a popular family walk? I love how you can get a great view from all sides and when you turn inwards, you have a piece of history right in front of you.
ps I notice you posted from the HYBH community. Just so you know, it doesn't automatically pin posts to the Pinmapple unless you post from the HYBH app
The walls are usually crowded with people walking along them. That's why I tend to visit during winter or bad weather when it's less busy. I just got really lucky with the visibility that day, probably because it was a Sunday and right in the middle of COVID-19 so all the tourist programs were closed.
I wanted to try HYBH community and I like it. I'll give the app a close look soon, but I don't really like posting from my phone unless I have no choice (travelling without netbook). I pinned this location in my first blog about the larger fortifications and impressive buildings at the Northern End that I featured last fall. Suwon is actually worth visiting for tourists coming to Korea if they don't have time to get to somewhere far from Seoul because it's only a 40-minute train or bus ride and is an easy day trip.
