Seoul in 4 Days — Palaces by Day, Neighbourhoods by Night

Budgeted at ₩18,000, and this is the single best-value decision of the trip. Seoul's base subway fare is ₩1,550 with a card, and a day of this itinerary is four to six rides — so four days of pay-as-you-go lands around ₩30,000. The Climate Card short-term tourist pass costs ₩15,000 for five days of unlimited Seoul subway and Seoul city buses, plus ₩3,000 for the physical card itself: ₩18,000 all in. Checked 25 July 2026 and there is a live caveat. Seoul is retiring the 30-day Climate Card — it can only be recharged until 31 July 2026 — and a successor called Climate Card Plus is still 'under discussion' with no launch date. The 1/2/3/5/7-day tourist passes are unaffected as of the check date, but confirm at the station machine, and if the product has moved, a plain T-money card (₩2,500–4,000, sold at every convenience store) does everything at ₩1,550 a ride. Two things the Climate Card does not cover: the Airport Railroad express and the Shinbundang Line. Neither matters here — every stop in these four days is on a Seoul line — but the airport is on you. From Incheon, the AREX all-stop train to Seoul Station is about ₩4,750 and takes ~60 min; the nonstop express is roughly ₩11,000 and saves ~15 min, which is rarely worth it.

₩3,000, and closed every Tuesday — this single fact fixes the shape of the whole trip. Hours are seasonal: 09:00–17:00 Nov–Feb, 09:00–18:00 Mar–May and Sep–Oct, 09:00–18:30 Jun–Aug, last admission an hour before. Time your arrival for the Changing of the Royal Guard at 10:00 (repeated at 14:00) in the Heungnyemun courtyard, which is inside the free outer zone — you do not need a ticket to watch it, and the ₩3,000 is for everything behind that gate. Two smaller ceremonies, the Gwanghwamun Gate Guard on Duty, run at 11:00 and 13:00. All of it can be cancelled or cut short in rain, snow or 'very unhealthy' fine-dust days, because the costumes and instruments do not tolerate moisture — do not build the morning around it in bad weather. Behind the ceremony the palace itself is the largest of the five and the most comprehensively rebuilt: burned in the 1592 Japanese invasions, left in ruins for 270 years, reconstructed from 1867, then systematically dismantled under Japanese rule and re-reconstructed from 1990 onward. What you are walking through is a 20th-century argument about national memory as much as a 14th-century palace, and Geunjeongjeon's throne hall and the Gyeonghoeru pavilion on its pond are the two set pieces. Free entry if you arrive in hanbok — rental shops ring the palace at ₩15,000–30,000 for four hours, which is a wash on the ticket price but a genuinely popular thing to do here and not remotely mocked by locals.

₩10,000 and the most fun lunch in Seoul that is not a restaurant. Go to the Doshirak Cafe on the second floor, buy an empty lunch tray and a bag of yeopjeon — traditional brass coins, ₩500 each, minimum 20 recommended per person — then walk the market floor spending them: one to three coins per portion at any stall flying the participating sign. Tteokbokki, jeon, fried things, braised things, mayak gimbap. Unused coins are refunded on the way out, so over-buying costs nothing. Closed Mondays and the third Sunday of the month (official Visit Seoul listing) — note that this is a different closure day from Gyeongbokgung's Tuesday, which is precisely why day 1 can be neither a Monday nor a Tuesday. The cafe runs roughly 11:00–15:00 on weekdays and 11:00–16:00 at weekends, and the coin desk stops selling around an hour before it closes, so 12:00 is not a lazy start here, it is the sensible one. Ten minutes' walk from Gyeongbokgung Station exit 2, through Seochon — the low-rise neighbourhood west of the palace that Bukchon's crowds never reach.

Free, and it sits inside the Gyeongbokgung grounds at the southwest corner — Gyeongbokgung Station exit 5 puts you at the door. This is the counterweight to the morning: the palace shows you rebuilt architecture, the museum shows you the surviving objects, which is where Joseon actually still exists. Royal seals, the astronomical clocks, the king's palanquin, and the Uigwe — the obsessively illustrated royal protocol manuals that made the reconstructions upstairs possible in the first place. Open 10:00–18:00, with late opening to 21:00 on Wednesdays and Saturdays, last admission an hour before. Sources genuinely conflict on whether it closes Mondays: the national tourism listing gives only Jan 1, Seollal and Chuseok as closures, while several aggregators state a Monday closure. Since this itinerary's day 1 can only fall on a Wednesday or Thursday the question never bites, but check gogung.go.kr — the museum's own site is the authority — if you reorder the days. Seventy-five minutes covers the two floors that matter, and it is air-conditioned in August and heated in January, which on a Seoul day 1 is not a trivial argument.

Free. Start at Cheonggye Plaza near Gwanghwamun and walk east, down at water level, a full storey below the traffic. Until 2003 this was a covered sewer with an elevated motorway on top of it; tearing the motorway down and daylighting the stream was the most argued-about civic project in modern Seoul and is now the thing every other city sends delegations to look at. The stone stepping-crossings and the strip of shade make it the best possible use of the flat mid-afternoon, and it deposits you eastward toward Euljiro. Two practical notes: after heavy rain the walkways are closed and gated at street level, without much explanation, and there is very little shelter down there — this is a fine-weather stop with an easy street-level bail-out at any bridge. If you would rather rest, this is also the natural point to drop back to the hotel for an hour before the evening, which genuinely runs late.

₩11,000 for the kalguksu and the noodles are refilled free. A Michelin Bib Gourmand every year since the Seoul guide launched in 2017, a Seoul Future Heritage site, and open since 1966 — and it serves four dishes, total. Order the kalguksu: hand-cut wheat noodles in a heavy chicken-and-anchovy broth, dumplings sitting on top, minced pork underneath. The mandu is ₩12,000 if you want a second thing on the table. The kimchi served with it is a garlic kimchi made specifically to stand up to the broth and it is genuinely fierce — this is not the polite hotel-breakfast version. Expect a queue at peak; it moves fast because nobody lingers, and there are annexe branches within a couple of blocks if the main room is impossible. No reservations, cash and card both fine. It is the exception to everything in the note below about eating in Myeongdong.

Budget ₩8,000 and treat this as dessert and spectacle, not dinner. The carts set up around 16:00 and the street is at full volume 17:00–22:00: egg bread, tornado potato, grilled cheese lobster, hotteok, ₩5,000–8,000 tteokbokki. It is a real thing worth seeing once and it is also, unambiguously, the most touristed strip in Seoul. The rule that saves you: never eat sitting down on the main street. Any restaurant on Myeongdong-gil with a six-language menu board and a photograph of every dish is priced for people who will not come back — walk one block off the strip and the same meal costs a third less. The carts themselves are fine, priced openly, and mostly cash. This is also the K-beauty district, so if anyone in the party wants that, now is the hour rather than a separate trip. Myeongdong Station is Line 4; you are ten minutes' walk from the cable car base.

Skip the observatory. It is ₩26,000 per person to ride a lift up a tower in order to look at a city you are already standing above — the Seoul Tower Plaza at the base of the tower is free, open late, and gives you the same 360-degree view of the basin with the mountains black behind it. Spend the money on tomorrow's dinner. Get up Namsan for nothing: the 01A and 01B Namsan circular buses run to the tower itself every 6–9 minutes (01A) and 15–18 minutes (01B), first bus 06:30 and last 23:00, and they are ordinary Seoul city buses, so the transit pass you bought this morning already covers them — but they are cashless, card or phone only. Pick them up at Chungmuro Station exit 2 or Dongguk University Station exit 6. The Namsan Cable Car is the paid alternative and the one figure in this itinerary I could not pin down: published adult round-trip fares ranged from ₩8,000 to ₩15,000 across sources on 25 July 2026, so check the board before you commit — the free Namsan Orumi inclined elevator takes you to its base station either way. Walking up from Myeongdong is 30–40 minutes on a stepped path, pleasant in spring and autumn, punishing in August. Going after dark is the entire point: Seoul at night from up here is the image people come home with, and the padlock fences are on the way to the plaza.

₩3,000, closed Mondays, and the better palace of the two — which is why it gets the fresh morning rather than a tired afternoon. Where Gyeongbokgung is a rebuilt grid asserting royal authority on a north-south axis, Changdeokgung was laid into the contours of the hill behind it, and that decision is why UNESCO listed it in 1997. It was also the palace that actually worked: kings preferred it, and it stayed in use as a royal residence into the 20th century. Hours 09:00–18:00 Feb–May and Sep–Oct, to 18:30 Jun–Aug, to 17:30 Nov–Jan, last entry an hour before. Sixty minutes covers the throne hall, Injeongjeon, and the astonishing Nakseonjae complex — unpainted wood, deliberately austere, built for a concubine and later home to the last of the royal family until 1989. Do this first, then the garden, because the garden tour will not wait for you.

₩5,000 on top of the ₩3,000 palace ticket, and book it online before you leave home — this is the one genuinely reservation-critical item in four days. Entry is by timed guided tour only, capped at about 100 people per slot, and the English tours run roughly 10:30, 11:30 and 14:30 with an extra 15:30 slot February to November. Slots sell out days ahead in the autumn foliage weeks and cherry blossom fortnight; a limited number are released on the day at the ticket office, which is a gamble rather than a plan. Book through the official Korea Heritage Service reservation system, and note the times drift seasonally — confirm the exact English slot when you book rather than trusting any blog, including this one. What you get for ninety minutes of not being allowed to wander: a 78-acre royal garden that was closed to the public until 1976, built as a sequence of ponds and pavilions revealed one at a time as the path turns. Buyongji pond with its square-and-circle cosmology, the Juhamnu library above it, and Ongnyucheon, where a stream was carved into a channel so that the court could float wine cups down it while composing poems. Go in mid-October if you have any choice in the matter.

₩12,000 and a 2026 Michelin Bib Gourmand that has been in the same spot since 1982. Sujebi is hand-torn dough dropped into anchovy broth — peasant food, and the least glamorous thing in this itinerary, which is rather the point after two palaces. Get the potato pancake alongside: grated rather than blended, so it fries crisp at the edge and stays chewy in the middle. No reservations, walk-in only, and it is always busy; arriving at 12:30 rather than 13:00 is worth ten minutes of queue. Cash and card. It sits at the top of Samcheong-dong's main street, which means you can walk down through the galleries and small shops afterward straight into Bukchon rather than doubling back.

Free, and legally restricted in a way most guides still have not caught up with. Since November 2024 the core residential block around Bukchon-ro 11-gil is a designated Special Management Area: tourist visits are permitted only between 10:00 and 17:00, and entering outside those hours for tourism carries a ₩100,000 fine, enforced since March 2025 after a grace period. From 1 January 2026 chartered tour buses are also banned along a 2.3 km stretch of Bukchon-ro, Bukchon-ro 5-gil and Changdeokgung 1-gil at all times. A 14:00 arrival sits comfortably inside the window and gets you out before it shuts. The reason for all of this is the thing to keep in mind while you are there: roughly 6,000 people live in these houses, the alleys are their front doors, and the residents lobbied for years to get the curfew. Keep your voice down, do not photograph into courtyards, and obey the signed quiet zones — there are staff on the corners now. What you came for is the run of tiled rooflines stepping down the hill with the modern city stacked up behind them, best from the upper end of Bukchon-ro 11-gil looking south. Ninety minutes is plenty; this is a place to walk through, not to consume.

Free to walk. Insadong is the old antiques-and-calligraphy street, now half craft shops and half tourist tat, and the trick is knowing which half you are in: the good stuff — hanji paper, brushes, ceramics, tea — is up the side alleys, and the main drag is souvenirs. Ssamziegil is the one built thing worth going into: a shopping complex designed as a single continuous ramp spiralling up four floors around an open courtyard, so there are no stairs and no dead ends, just small independent studios the whole way up. Free, open to about 20:30. Insadong is also the easiest place in Seoul to sit down for a proper tea — the traditional teahouses signposted off the alleys serve omija, jujube and citron rather than anything green. If you would rather trade this for something newer, Ikseon-dong is fifteen minutes' walk east: the same era of hanok housing, converted into small bars and restaurants instead of shops, and considerably more fun after dark.

Budget ₩15,000 and come hungry. Korea's oldest permanent market, open since 1905, and the food alley at its centre is the loudest, most crowded, most enjoyable eating in the city — plastic stools, no menus in any language, vendors shouting. The three things to actually eat: bindaetteok (mung-bean pancakes ground fresh and fried in a shallow pool of oil — Sunhee-ne Bindaetteok is the Netflix-famous stall and therefore the longest queue; any stall where you can watch the stone mill turning is as good), yukhoe (raw seasoned beef, sold along its own dedicated alley at the eastern end), and mayak gimbap, tiny mustard-dipped rice rolls whose name translates uncomfortably as 'narcotic gimbap'. One caveat you should not skip. A 2024–25 run of viral videos exposed vendors serving tourists short portions at inflated prices, it became a national news story, and Seoul city and the merchants' association responded with posted prices and spot checks. It is much better than it was, but the habit that protects you costs nothing: look at the posted price and confirm it before you sit down. Expect roughly ₩5,000–8,000 a plate. Most stalls take card now; carry some cash anyway. Weekday evenings are the sweet spot — Saturday afternoons are genuinely unpleasant, and a minority of stalls close on the fourth Sunday.

Free, and deliberately the last thing you do today rather than a daytime stop — Zaha Hadid's building is a far better object lit at night, when the aluminium panels stop reading as grey and the whole thing looks like it was poured rather than built. The exterior plazas and the walkable roof are open 24 hours and cost nothing; the interior halls run roughly 10:00–19:00 and close Mondays, and the Design Museum's ticketed exhibitions are ₩8,000–15,000, none of which you need at this hour. The LED Rose Garden — 25,550 lit roses on the mound beside the building, installed as a temporary piece in 2015 and kept because nobody wanted it removed — switches on at dusk and is the reason to come after dark. Dongdaemun around it is a wholesale fashion district that genuinely trades through the night, so the streets are busy at 21:00 in a way that surprises people. One stop from Gwangjang on Line 2/4/5 at Dongdaemun History & Culture Park, or a fifteen-minute walk if the evening is mild.
