Chunghyeon Museum is 1.1 mi (1.8 km) from central Gwangmyeong, why not stop by during your stay. Why not take a stroll along the riverfront and watch the sunset while you're here? It's also full of great shops and restaurants, so you can spend the afternoon having a wander. If you want to experience more of the culture Gwangmyeong has to offer, head to Gasan Digital Complex, Guro Digital Complex, and Seoul National University.
