The Jamsugyo guitar flash mob is the key May 24 program for visitors looking at the Jamsugyo Picnic schedule. Officially titled “Romantic Hangang Guitar Flash Mob,” the free special program is listed for Sunday, May 24, 2026, from 5:30 p.m. to 6:30 p.m. at the special stage on Jamsugyo Bridge.1
For readers planning around Jamsugyo Picnic or the broader car-free Jamsugyo festival, the practical points are simple: the performance is free, it uses an advance reservation process, and it is part of the 2026 Car-Free Jamsugyo Ttukbeok Ttukbeok Festival running at Jamsugyo Bridge and Banpo Hangang Park.12
Jamsugyo Guitar Flash Mob: Time, Place, and Format

The program is scheduled for a one-hour evening slot, from 5:30 p.m. to 6:30 p.m., on the special stage installed at Jamsugyo Bridge.1 The Seoul Future Hangang Headquarters event notice also identifies the May 24 guitar flash mob as a special-stage acoustic guitar performance featuring singer-songwriter Beomjin and about 300 citizens.2
That format matters for planning. This is not described as a standard seated concert, nor as a general busking session; the source material presents it as a large-scale acoustic guitar joint performance. Financial News, through a News1 report, also describes the May 24 “Romantic Hangang Guitar Flash Mob” as a large acoustic guitar collaboration with Beomjin and roughly 300 players.3
The official festival page lists the program as free, but it also states that it is operated by advance reservation. It separately notes consent for collection and use of personal information and an external advance reservation process.1 Because the source material does not provide a ticket price, ticket sale time, or refund policy, the available guidance is limited to what is confirmed: it is free and reservation-based.
How It Fits Into the 2026 Car-Free Jamsugyo Festival
The guitar flash mob is part of the 2026 Car-Free Jamsugyo Ttukbeok Ttukbeok Festival, held every Sunday from April 26 to June 14, 2026, around Jamsugyo Bridge and Banpo Hangang Park.2 Seoul Culture Portal’s release describes the first-half 2026 festival as an eight-week Sunday event and notes that popular content such as the acoustic guitar flash mob and sunset yoga was strengthened, alongside expanded play zones and photo zones.4
For visitors, the broader festival context affects timing and movement. Dong-A Ilbo reported, citing Seoul City, that during the festival period vehicle traffic is restricted every Sunday from 11:00 a.m. to 11:00 p.m. across an approximately 1.1 km section.5 That car-free setup is central to the event’s identity, but it also means visitors should plan around pedestrian access and the festival’s Sunday operating pattern rather than expecting ordinary road traffic conditions.
The Korea Tourism Organization’s Visit Korea festival listing also places “Romantic Hangang Guitar Flash Mob” in the fifth-week special program lineup, alongside regular festival areas such as Dalbit Playground, Dalbit Restaurant, Dalbit Market, and Dalbit Rest Area.6 In practical terms, that means the guitar flash mob is one scheduled special program within a larger Sunday festival environment, not the only activity available around the bridge and Banpo Hangang Park.
Planning Notes for Visitors and Participants
If your main goal is to see the guitar flash mob, the verified time window is 5:30 p.m. to 6:30 p.m. on May 24, 2026.1 The sources do not state a separate admission fee for spectators, and the official program page identifies the special program as free.1
If your goal is to take part, the key confirmed detail is that the official page describes the program as advance-reservation based.1 The source material does not give a full public participation procedure beyond the external advance reservation and personal-information consent notice, so readers should treat registration as a required step rather than assuming walk-up participation is available.
For schedule planning, it is also useful to separate the flash mob from the full festival hours. The broader festival takes place on Sundays during the April 26 to June 14 period, while the May 24 guitar flash mob itself occupies the 5:30 p.m. to 6:30 p.m. slot.2 The traffic restriction reported for the festival period runs much longer, from 11:00 a.m. to 11:00 p.m. on Sundays, across about 1.1 km.5
Because the source material identifies Jamsugyo Bridge and Banpo Hangang Park as the festival area, visitors should expect the flash mob to be integrated into that riverside festival setting. The official program location, however, is more specific: the special stage on Jamsugyo Bridge.1
