The short answer: For Seoul pop-up stores in October 2026, start with your dates and reservation access. Mrs. GREEN APPLE in Yeouido ends October 5; BTS DALMAJUNG in Yongsan ends October 11. For Seongsu, use our separate neighbourhood guide rather than trying to fit every district into one day.
Checked September 30, 2026 (Korea time). This is a selected early-October planning guide based on organiser notices, not a complete city calendar or a report of personal visits. Booking availability has not been verified. All dates below are in 2026.
Which Seoul pop-ups fit your October trip?
| Area / event | Announced dates | Before travelling |
|---|---|---|
| Yeouido: Mrs. GREEN APPLE “POPS” | September 26–October 5 | Naver advance reservation |
| Yongsan: BTS DALMAJUNG | September 29–October 11 | Weverse reservation; purchase QR required |
| Seongsu: separate neighbourhood selection | Dates vary by event | Read the linked event-by-event guide |
October 1–5 falls within both featured events’ announced runs. October 6–11 leaves BTS from this pair. Neither is a later-October option. If your trip starts after October 11, do not book transport around either listing.
Yeouido: how do you book Mrs. GREEN APPLE “POPS”?
The artist’s announcement places the pop-up at The Hyundai Seoul, fifth floor, EPIC SEOUL. It combines album-related displays and experiences with original merchandise. This is the Yeouido event, not a Seongsu shop.
Paste into Naver Map: 더현대 서울 — 서울 영등포구 여의대로 108. The department store’s directions describe an underground connection from near Yeouido Station Exit 3 to its B2 entrance. Your destination inside is 5F.
The September 24 booking and merchandise notice requires a Naver reservation, with slots offered in 30-minute intervals. That describes the booking interval, not a verified maximum stay. The notice limits identical items to two per person and warns that stock and purchase limits can change.
Before making this a fixed stop, try completing the reservation with your own account. We have not verified the foreign-account booking flow or remaining slots. A published booking link is not confirmation that you can reserve, and a reservation is not a guarantee of merchandise stock.
Yongsan: can you visit BTS DALMAJUNG without a booking?
Venue: HYBE Yongsan 1F, 서울 용산구 한강대로 42. The official visitor guide lists 11:00–20:00 KST. Book through its Weverse link using a registered account; each reservation admits one person. Show the live reservation QR, not a screenshot.
The important distinction is viewing versus shopping. Staff may allow unreserved visitors to view or experience the pop-up when conditions permit, but merchandise purchases require a reservation QR. Do not rely on walk-in access if buying merchandise is your reason for going.
The guide asks reserved visitors to arrive ten minutes before their slot, treats arrivals more than twenty minutes late as no-shows, and allows up to one hour inside. It lists credit cards, Samsung Pay and Apple Pay for merchandise; cash is not accepted, and some cards may be declined. These are event-specific rules, not a promise about every overseas card.
Should you choose Seongsu instead?
If Seongsu is already part of your trip, start with the October Seongsu pop-up dates and reservation guide. It covers TWS, ENHYPEN, 10MONTH and T Factory separately. Keeping those venue details together makes it easier to plan a neighbourhood visit without duplicating the full guide here.
Our planning suggestion: secure the event you most want first, then choose nearby activities around that booking. Treat Yeouido, Yongsan and Seongsu as separate stops with travel between them—not as a single walkable pop-up route. Avoid consecutive reservations until you have checked a route for your actual departure time.
What if you are visiting before a flight?
A pop-up reservation does not make a tight airport schedule workable. Use the before-flight planning guide to work backwards from departure. For a connection between flights, start with whether you can leave Incheon Airport during a layover, before committing to a Seoul booking.
Frequently asked questions
Can one BTS reservation cover a couple? No. The visitor guide says one reservation admits one person; arrange each person’s booking separately.
Does “October pop-up” mean it runs all month? No. Both featured events finish in the first half of October. Match the final operating date to your visit, not just the month in the title.
Can I assume a sold-out online session accepts walk-ins? No. Follow the organiser’s specific rules. BTS distinguishes conditional viewing access from merchandise purchases; the Mrs. GREEN APPLE notice specifies advance reservations.
