Thanks to our tour guide, Janggun Oppa, for his excellent service. He explained the features and best photo spots at each attraction and even helped us take pictures together, resulting in many beautiful photos on my phone. He also gave us suggestions for Chinese food; the barbecue we ordered with friends was really delicious. It's definitely worth spending a day here for a relaxing stroll. The dawn redwood forest in winter is truly beautiful; enjoying the scenery along the way was leisurely and romantic. You can even try roasting marshmallows! While waiting for the return ferry, we found a red mailbox nearby. We picked out postcards at the souvenir shop across the street. The stamps were purchased at the visitor center. I was lucky enough to send a postcard from Nami Island; I look forward to receiving it... Next time, I'd like to come in a different season to experience the different natural beauty of Nami Island under different climates...
