I booked this tour well in advance, initially worried that rain might affect the activities, but luckily the weather was great. Plus, our guide, NIMO, had added us on Laid-off the day before for easy communication. He provided detailed explanations of each attraction's features and recommended a delicious place to eat: 31 Knife-Cut Noodles. His photography skills were also top-notch; he took beautiful photos of me in every single one. On the way back, he even recommended good restaurants near Seomyeon Station. I'm so happy to have participated in this trip; it was definitely worthwhile!
