My visit to Hwaseong happened to coincide with the Hwaseong Festival in October. As a result I was rewarded with seeing the spectacular buildings of the Haenggung adorned with people dressed in traditional costumes and performing traditional rituals.
To avoid a longish walk I took either buses 11, 13, 36 or 39 from the station to and from the fortress. Besides the metro, there are faster mainline trains from Seoul to Suwon.
