The city of Suwon was just 40 minutes away by bus. There wasn't a whole lot to do in Namyang, but I could pop in to Suwon to see a movie, or go to Outback Steakhouse. I could also catch the train into Seoul, which only took 35 minutes, so day trips to Seoul were quite feasible.
Suwon is also home to Hwaseong Fortress, a UNESCO world heritage site.
