Directions: Sadang Station (Line 2/1) Exit 4, walk 5 minutes and make a sharp right and walk up the hill. Follow other climbers or look out for hiking stores. It's not hard to find, fear not. And getting lost is always fun. We entered here at Sadang station, hiked for 3 hours to the peak, and then hobbled down on numb legs into Seoul National University which nuzzles its northwest boundary. From there we thankfully hopped on a bus and made our way home.
