As the lingering summer heat retreats and autumn settles in, October deepens the season's colors and textures across the country. From golden rice paddies and lanterns drifting on dark rivers to ancient fortress walls, forests burning red and the quiet perfume of late-blooming flowers, festivals nationwide are ready to stir the senses. Here is a look at some of the standout events that promise to leave a lasting impression at the height of autumn.

Wishes set adrift on an autumn night

Jinju, South Gyeongsang Province, will host the 2026 Jinju Namgang Yudeung Festival at Jinjuseong Fortress and along the Namgang River from Saturday through Oct. 18. The festival traces its origins to the Imjin War, when the people inside Jinjuseong lit lanterns to signal their safety to family members outside the walls and to kindle the spirit of resistance. It is held in autumn, when clear, dry nights make the lanterns' reflections on the Namgang River most vivid.

Throughout the festival, the lanterns are lit daily from 6 p.m. to midnight. Watching them drift slowly with the gentle current in the cool night air evokes both the memory of fierce battles fought long ago and the quiet lyricism of autumn evenings.

On the water, rows of floating lanterns combine with illuminated fortress walls framing Chokseongnu Pavilion to create a spectacular sea of light. Visitors can cross a pontoon bridge connecting both banks of the Namgang for a close-up view of the lanterns, and hands-on programs — including a wish-lantern hanging activity and a lantern-floating experience — invite direct participation. Drone light shows and fireworks add to the spectacle each night.

An autumn renaissance along the fortress walls

The 63rd Suwon Hwaseong Cultural Festival, a traditional arts festival set against the graceful curves of the UNESCO World Heritage-listed Suwon Hwaseong Fortress, runs from Sunday through Oct. 11 at the fortress and Hwaseong Haenggung Palace.

Beneath a clear autumn sky, the sight of yellowing wild grass against the fortress's weathered brick walls creates a tranquil atmosphere unique to Hwaseong in fall. Walking the fortress path in the crisp autumn breeze, visitors can almost feel King Jeongjo's passion for his people and the brilliance of late Joseon-era craftsmanship.

The festival's centerpiece is the reenactment of King Jeongjo's royal procession on Sunday, recreating the king's 1795 journey to Hwaseong with his mother, Lady Hyegyeonggung Hong, in a meticulously researched parade that transforms the city center into a scene from a grand historical drama. A themed performance inspired by a nighttime military drill, "Suwon Fantasy Yajo," runs from Wednesday through Oct. 11 at 8 p.m. on a special stage at Yeonmudae. At Yongyeon Pond below Banghwasuryujeong Pavilion, a water performance called "Seonyumong" takes place from Monday through Oct. 11 at 7 p.m.

A quiet healing forest painted in autumn colors

Hwadamsup forest in Gwangju, Gyeonggi Province — one of the greater Seoul area's most celebrated autumn foliage destinations — will hold its 2026 Autumn Foliage Festival from Oct. 23 to Nov. 15. Spanning 165,000 square meters, the forest offers a restorative natural retreat just a short distance from the city.

True to its name, which evokes the idea of sharing warm conversation, Hwadamsup in autumn invites visitors to set aside the pressures of daily life. The crunch of fallen leaves underfoot and autumn sunlight filtering through a canopy of red and yellow foliage make even a simple walk feel like a moment of calm.

The forest is home to more than 400 varieties of maple, including Korean maples and downy maples, producing a delicate, richly varied display of red that resembles a watercolor painting come to life. Visitors can stroll along gently sloping deck walkways or ride a monorail through a tunnel of red maples to take in a panoramic view of the forest. The festival operates entirely on a pre-booked, capacity-controlled basis — about 1,000 visitors per hour and a maximum of 11,000 per day. Reservations are available through the official website.

A golden sea of abundance from the earth

The 28th Gimje Horizon Festival runs from Thursday through Monday at Byeokgolje and surrounding areas in Gimje, North Jeolla Province. Set against the vast Honam Plain, the festival celebrates the roots and labor of a people who have worked the land for generations.

Under a high, clear autumn sky, golden rice paddies stretch to the horizon like an inland sea, conveying the generosity of the earth. Standing before waves of ripening grain, visitors are reminded of the value of the soil beneath their feet.

Festivalgoers can step into yellowed rice paddies to harvest stalks with a sickle, catch grasshoppers leaping through the straw, and cook freshly harvested new rice in a cast-iron cauldron over a wood fire. After dark, lighting installations illuminate the Byeokgolje grounds, and visitors can enjoy nighttime experiences — including an LED torch play — as part of an event called "A Night on the Horizon Lit by Light." Traditional performances round out the program, among them the Byeokgolje legend twin-dragon play, a tightrope-walking show and a national farmers' music competition.

A gentle fragrance to close out autumn

The 23rd Iksan Ten Million Chrysanthemum Festival will bring autumn to a fragrant close at Jungang Sports Park in Iksan, North Jeolla Province, running for 10 days from Oct. 23 to Nov. 1. The event centers on the chrysanthemum — Iksan's official city flower — which blooms even as late-autumn frost sets in.

Chrysanthemums release their deepest fragrance at the very end of autumn. Encountering ten million blooms along a path that has grown cold and bare offers quiet comfort to weary visitors.

The park will feature oversized chrysanthemum sculptures evoking the national treasure Mireuksa Temple Stone Pagoda and the spirit of Baekje King Mu, telling the story of a millennium of Baekje history through flowers. Carefully tended chrysanthemum bonsai works showcase the artistic essence of the season, while an illuminated evening walkway at dusk creates a romantic, storybook atmosphere among the blooms.
