How To Get There: We took the subway to Suyu Station of Seoul Line 4. We exited at #3 and crossed half the road to catch a blue bus #170. We rode the bus to the end of the line (right after it u-turns). We 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.
