Seosan Chrysanthemum Festival 2026 Dates, Stage Times, Radish Harvest – Before Visiting the Gobuk-myeon Mum Maze

It’s the season when the fields of Gobuk-myeon, Seosan,
fill with the scent of chrysanthemums in late autumn 🌼

The 26th Seosan Chrysanthemum Festival (제26회 서산국화축제)
runs from November 6 (Fri) to 15 (Sun),
for ten days around 31-1 Boknamgol-gil,
Gobuk-myeon, Seosan.

Admission is free.

I’ve summarized the official blog of the
Seosan Chrysanthemum Festival Promotion Committee:
its festival notice (October 5), leaflet (October 6)
and garden updates (October 7 and 8).

🎪 About the Festival

This year’s poster slogan is
”Follow the flower path, follow the maze, meet autumn.”

The Seosan Chrysanthemum Festival Promotion Committee
hosts and organizes it,
with Seosan City and Seosan City Council as sponsors.

The leaflet’s greeting introduces a wide chrysanthemum garden
grown by local residents’ hands, mums set among apple trees,
and a gourd tunnel.

On October 8 the committee’s blog said
the chrysanthemums were still green
and expected them to start blooming around the fourth week of October.

🌼 What Can You See?

This year’s highlight is the Chrysanthemum Maze Garden.
The committee’s blog says it was built
over a larger area than in other years,
and teases that a secret is hidden in the maze.

Here’s what the leaflet lists.

The rock-planted and bonsai mums are works
made by the “chrysanthemum keepers” (국화지기)
while taking a prize-mum growing class this spring.

✨ What’s On and When?

Stage performances are concentrated
on opening day and the two weekends.
Here is the leaflet’s performance schedule by date.

The leaflet notes that the performance schedule
may change depending on circumstances.

🥬 What Experiences Are There?

There are two experience programs:
chrysanthemum picking and
altari radish harvesting.

The altari radish harvest runs only three days,
the 11th (Wed), 14th (Sat) and 15th (Sun),
and you need to sign up in advance with the
Agricultural Technology Center’s Technology Extension Division (041-660-3935).

The performance schedule also lists
an altari radish kimchi-making demonstration
on the 8th (Sun) at 15:00.

🚗 How Do You Get There?

These are the leaflet’s directions.
Both routes take National Route 29.

The map below shows the Gobuk-myeon Administrative Welfare Center,
which the leaflet also gives as a navigation keyword.
The festival grounds are around 31-1 Boknamgol-gil in the same Gobuk-myeon.

👨‍👩‍👧 If You’re Visiting with Kids

The committee’s blog picks the Topiary Plaza
as the place children like most.
On the venue map it shares a spot with the chrysanthemum tower near the entrance.

The leaflet’s venue map marks
a nursing room, two restrooms
and the general information office.

The blog also says the maze garden spreads out
in front of the willow photo zone and the central observatory.
