Seoul Park Music Festival, June 20–21: global K-pop and Korean indie bands on one outdoor lawn — and how foreigners book it

Most K-pop concerts give you one lane of Korean music. Seoul Park Music Festival gives you the whole road. On June 20–21, 2026, Olympic Park's 88 Lawn hosts 29 acts that run from arena-filling global K-pop — MONSTA X, CNBLUE, Sandara Park — straight into the Korean indie and live-band scene that foreign listeners are only now starting to discover: Jannabi, Silica Gel, 10cm, Jung Seung-hwan, Kwon Jin-ah. It's a rare weekend where the same stage holds both the names you flew in for and the bands you'll fly home obsessed with. Here's the lineup, the prices, and the one booking detail foreign visitors keep getting wrong.

The numbers, locked-in

• Dates: Saturday, June 20 and Sunday, June 21, 2026.
• Venue: Olympic Park — 88 Lawn (88잔디마당) plus the Ticketlink Live Arena (the Handball Stadium), Songpa-gu, Seoul.
• Acts: 29 total, across two days.
• 1-DAY ticket: ₩119,000.
• Sales channels: NOL Ticket and Naver booking (Korean side); NOL World for foreign passports (more below).
• Format: outdoor lawn festival — bring it for weather, not for a roof.

Why this lineup is different — global K-pop meets the Korean band scene

Most festivals pick a lane: a pure K-pop bill, or an indie/band bill. Seoul Park Music Festival deliberately doesn't. The 29-act roster spans four worlds at once, and the overlap is the whole point.

• Global K-pop names: MONSTA X, CNBLUE, and Sandara Park (formerly of 2NE1) — all acts with established international fandoms who tour and chart well beyond Korea.
• Korean indie / rock bands: Jannabi and Silica Gel — two of the most important names in Korea's current band scene, both with fast-growing overseas recognition. If you only know Korean music through K-pop, these are the acts that rewrite what you think the country sounds like.
• Ballad and singer-songwriter: 10cm, Jung Seung-hwan, Kwon Jin-ah — the voices behind the OSTs and streaming staples you've probably already heard without knowing the names.
• Rising bands: ONEWE, Damons Year, and more across the two days.

That spread is the reason to choose this festival over a single-artist concert. A K-pop-only ticket shows you one slice of the industry. This shows you the full spectrum of how Korea actually makes and plays live music — idols, bands, balladeers, and the indie underground — across one outdoor weekend. For a foreign fan, it's the most efficient crash course in Korean live music you can buy.

The foreign-passport channel — NOL World

Here's the part international guides skip. The Korean-side tickets sell through NOL Ticket and Naver booking — and Naver booking typically requires a Korean ID to clear verification. If you're a foreign visitor, that's a wall, not a bug in your browser.

The route built for you is NOL World, the English/multilingual sister platform of Interpark's domestic ticketing site — the same channel that handles Weverse Con and SEVENTEEN's foreign-passport ticketing.

• English checkout: the whole flow runs in English, with foreign credit cards accepted.
• Passport verification: NOL World verifies the passport you upload to confirm foreign-national status — keep it ready before you start.
• Separate pool: foreign visitors book from a channel built for them, instead of fighting the Korean-ID-gated Naver queue. Same ticket, a route that actually lets you through.

If you've tried Naver booking with a foreign ID and it bounced you, you're not doing it wrong — you're on the wrong channel. Move to NOL World. We covered the exact same dual-channel design for Weverse Con Festival and SEVENTEEN's CARAT LAND; this is the Korean live-event standard, not a one-off.

The 2026 lineup

The festival confirmed a 29-act bill spanning indie, bands, K-pop, and ballad. Highlights across the two days:

• K-pop: MONSTA X, CNBLUE, Sandara Park.
• Bands / rock: Jannabi, Silica Gel, ONEWE, Damons Year.
• Ballad / singer-songwriter: 10cm, Jung Seung-hwan, Kwon Jin-ah.
• …and more across the 29-act roster — check the official site for the day-by-day split and set times, which firm up closer to the date.

If you're building a trip around a single name, check which day they play before you buy — the 1-DAY ticket covers one date only, and the lineup is split across Saturday and Sunday.

Getting to Olympic Park

• Subway: Line 5 Olympic Park Station (올림픽공원역), Exit 3 — a short walk to the park grounds. Or Line 9 Hanseong Baekje Station (한성백제역), Exit 2.
• 88 Lawn: the open green inside Olympic Park used for the outdoor stages — follow festival signage from the station exits.
• Ticketlink Live Arena (Handball Stadium): also inside Olympic Park, a few minutes' walk from the lawn — same metro access.
• Arrival timing: for an outdoor general-admission lawn, get there early to claim a spot near the stage; entry queues compress at the gate before headliners.

June weather — this is the one to plan for

Late June in Seoul is the front edge of the monsoon season (장마). An outdoor lawn festival in this window can mean heat, humidity, sudden showers, or all three in one afternoon. Plan accordingly:

• Check the forecast the morning of — and pack a packable rain poncho. Large umbrellas are usually restricted at lawn events because they block sightlines.
• Sun and heat: 88 Lawn has minimal shade. Sunscreen, a hat, and a refillable water bottle go a long way.
• Footwear: wet grass plus a full day on your feet — closed shoes you don't mind getting muddy beat sandals.
• For the bigger picture on timing a June trip around the rains, see our Korea monsoon 2026 guide.

Don't buy from a stranger — the resale trap

When a festival ticket sells out, the scalper market wakes up. K-pop and band events in Korea are a recurring target for resale scams — fake "extra ticket" posts on social media, inflated DM resales, screenshots that turn out to be nothing. Book only through the official channels above. If a deal lives on someone's social feed instead of a ticketing platform, treat it as a scam until proven otherwise. We broke down exactly how these run in our K-pop concert ticket scam guide.
