This is the walk I send every first-time visitor on: Gyeongbokgung in the morning, Bukchon after lunch, Insadong to finish. It is self-guided, so the only real costs are the palace ticket (3,000 KRW) and whatever you eat — budget around 25,000 KRW for the day including a proper lunch.
Start at Gwanghwamun
Take Line 3 to Gyeongbokgung Station, exit 5, and you surface inside the palace grounds. I prefer entering through Gwanghwamun itself, so I walk around to the front gate. The changing of the guard ceremony runs at 10:00 and 14:00 — arrive by 9:40 for the morning one and stand on the left side of the gate for the best angle.
Inside, do not rush to the throne hall with everyone else. Cut left toward Hyangwonjeong, the pond pavilion, which stays quiet for the first hour. The main courtyard, Geunjeongjeon, is genuinely impressive but it is the side corridors and the National Folk Museum corner that make the place feel lived-in.
Bukchon Without the Crowds
Exit the palace's east gate and walk ten minutes uphill into Bukchon Hanok Village. The famous photo spot on Gahoe-dong's hilltop alley gets mobbed by 11:00, so go straight there first, then wander the smaller lanes toward Samcheong-dong. Residents actually live here — keep your voice down and do not peer into courtyards.
Lunch and Insadong
For lunch I always end up at Tosokchon Samgyetang near the palace's west side — the ginseng chicken soup is rich without being heavy, and the line moves fast. Afterward, walk south into Insadong's main street for ssamziegil's craft courtyard and a cup of omija tea. If your legs still work, Cheonggyecheon stream is five minutes south and makes a flat, easy cool-down walk to end the afternoon.
