How To Get There: I took the subway to Suyu Station of Seoul Line 4. I exited at #3 and crossed half the road to catch a blue bus #170. I rode the bus to the end of the line (right after it u-turns). I took the first road after the u-turn (landmark: North Face store). This road is flooded with outdoor gear shops and it leads to Doseonsa Temple and Baegundae's trailhead of Bukhansan National Park.
