If you’ve ever taken the express bus from Sadang Station to Suwon, this is the charming lake you saw off the left-hand side of the road. The startlingly vivid autumnal colors make visits in the fall especially rewarding. This lake is relatively unknown to Seoulites, so don’t expect your Korean friends to know what you’re talking about when you mention it.
Getting there: Take Line 4 to Indeogwon Station and taxi up. It’s about 5 minutes from the station.
