Quick answer: Korea has two holidays that change how the whole country moves: Seollal, the lunar new year, and Chuseok, the autumn harvest festival. Both follow the lunar calendar, so the dates shift every year, and both run as three-day national holidays that in practice become four or five days of travel. Millions of Koreans move to their home towns at the same time: intercity rail and express coaches sell out weeks ahead, expressways run at a crawl, and a large share of independent restaurants and small shops close for two or three days. The mistake agents make is assuming Korea shuts down. It does not — the palaces, the major museums and the big attractions stay open and are often at their best — but the supply chain around a group changes shape, and a programme written for an ordinary Tuesday will not survive the week. Explera DMC Korea plans around the holiday calendar rather than discovering it late: coaches and guides are blocked early, restaurants are confirmed in writing as open, and the itinerary is built for the traffic that will actually be on the road.
The two holidays that matter, and the ones that also catch people out
Korea's holiday calendar mixes fixed dates with lunar ones. The fixed dates you can plan a year ahead; the lunar ones move, so confirm them for your travel year before quoting.
- Seollal — lunar new year, three days. Falls in late January or February. The single heaviest domestic travel period of the year, with the outbound crush before the holiday and the return crush after it.
- Chuseok — the harvest festival, three days. Falls in September or early October. Comparable movement, warmer weather, and a higher chance of a long weekend when the dates land next to a Saturday or Sunday.
- Buddha's Birthday — also lunar, in spring. Temples are busy and beautifully lit, which is an opportunity rather than a problem, but temple stays and temple visits need earlier booking.
- The fixed public holidays — New Year's Day (1 January), Independence Movement Day (1 March), Children's Day (5 May), Memorial Day (6 June), Liberation Day (15 August), National Foundation Day (3 October), Hangeul Day (9 October) and Christmas Day (25 December).
- The clusters — early May and early October each carry several holidays close together. When they fall beside a weekend, domestic demand behaves like a mini-Chuseok: full trains, full coastal hotels, and higher resort rates.
- Substitute holidays — when certain holidays fall on a weekend, a replacement weekday is observed. It is announced rather than fixed, so check the official calendar for your travel year instead of assuming.
What actually changes on the ground
Transport fills first, and it fills early
Intercity rail and express coaches are the pressure point. Seats for the holiday window open on a defined sale date and are gone quickly, so a group that needs rail on those days has to be ticketed the moment the window opens, not when the file is confirmed. Expressway journey times can double, which matters most for airport transfers and for any day trip that leaves the capital. Where the itinerary allows it, the answer is to keep the group inside one city for the peak days and move on either side of them.
Restaurants are the real risk, not attractions
Family-run restaurants often close for the holiday itself, and many do not announce it far in advance. A group of forty arriving at a closed door is the failure mode here. Hotel restaurants, department store food halls and larger chain operations stay open and are the safe base for holiday lunches and dinners, with independent venues used only where the DMC has written confirmation that they are trading.
Palaces and museums are open, and often free
The major palaces and national museums stay open through the holidays and have in past years waived or reduced admission over Seollal and Chuseok — worth confirming for your dates, because when it applies it turns a busy day into a good one. Expect Korean families in hanbok, seasonal folk programming in the palace grounds, and much larger domestic crowds than a normal weekday.
Hotels move in two directions at once
City-centre hotels in Seoul can soften as residents leave, which occasionally makes the holiday a buying opportunity for a city programme. Resort areas, Jeju and the east coast do the opposite and price up hard. Treat the two as separate markets rather than assuming one national trend.
Staffing needs stating in the contract
Guides, drivers and on-site staff work the holiday at premium rates, and the good ones are committed early. Agree the holiday supplement at contracting rather than at operation, and confirm in writing that the named guide is working — not that a guide will be found.
How to build a programme that works that week
- Block coaches and guides before anything else. Vehicles and licensed guides run out sooner than hotel rooms in the holiday window, and they are the components a DMC cannot manufacture at short notice.
- Plan a city-anchored itinerary for the peak days. Palaces, museums, markets that stay open, a hanbok afternoon and a night programme all work without the group getting on an expressway.
- Move the long transfers to the shoulder days. Arrive before the outbound rush or after it; keep the internal repositioning off the two heaviest travel days entirely.
- Confirm every meal in writing. Named venue, confirmed open, confirmed group size, with a fallback venue held for each holiday service.
- Add time to every transfer. Airport runs in particular: what takes an hour on a normal Wednesday needs a realistic allowance on the days either side of the holiday.
- Use the upside. Folk programming, palace events, lantern displays around Buddha's Birthday and the quieter business districts are genuinely better than the ordinary week, and they sell — if the itinerary is written to catch them rather than to avoid them.
What Explera does with the holiday calendar
Explera DMC Korea works the Korean holiday calendar as a planning input rather than a surprise: lunar dates confirmed for the travel year before anything is quoted; coaches, licensed guides and rail blocked at the earliest possible moment; holiday supplements agreed at contracting and shown in the costing; every holiday meal confirmed in writing with a named fallback; transfers timed for holiday road conditions rather than normal ones; and a 24/7 operations desk on Korea ground time for the days when the country is moving at once.
