Firefly programs across Korea open and close on very different schedules depending on species and region — for July and August 2026, Muju's late-season firefly tours (from late August) and its festival pre-booking window are the most reliable options right now.
Fireflies are visible in Korea anywhere from June to September depending on the species and location, which makes it genuinely hard to tell from a search result alone whether an event is still running or already over. This list sorts out what's actually bookable or open as of July–August 2026, program by program.
We've kept a few already-closed early-July programs on the list too, since they're the ones travelers most often get confused about. Match the timing you're planning around — early July, mid-July, or late August onward — and always double-check the organizer's latest notice before you go.
