In my four visits in Korea, I’ve been to Nami Island 3 times, all during fall.
In my previous times in Nami Island, this little lovely islet about 2 hours from Seoul, I have squeezed out whatever you can do here. I have:
1. stared in awe over the glorous autumn foliage. Nami is an amazing sight all year round, but I think the view is incomparable during fall.
2. biked around the island. You can walk the entire Nami island in 30 minutes from one end to another end. If you go around the island, it would take you around 2 and half hours. It’s completely doable on foot, especially when a normal tour here on an organized bus group would have you spending the entire day here. But if you want to make things interesting, rent a bike and do it winter sonata style — you in a cute dress just pedaling away with the wind.
3. eat. I am me so I eat.
