When staying in Seoul, taking a day trip to Incheon is great idea for a day off! We took the subway to Incheon on Buddha's birthday (a national holiday) and were able to spend the day outside, seeing the coast, and experiencing a town other than Seoul. We went to a market for a delicious lunch, walked around Wolmi Island park, and got dinner in Incheon's Chinatown. Our dinner was amazing and it felt very authentic, which was cool to experience in Korea. Overall, it was great to see another part of Korea and spend our day experiencing new things!
