Hantangang Stone Festa 2026 at Bidulginang Falls (Pocheon) — Schedule, 4K Trek Sign-up & Parking Before You Go

Autumn colors are settling
into the Hantan River canyon 🍂

The Hantangang Stone Festa
(한탄강 돌멩이 페스타 — “dolmengi” means pebble)
runs Sat, Oct 17 – Sun, Oct 18,
two days, around the multipurpose plaza
at Bidulginang Falls (비둘기낭 폭포) in Pocheon.

At the trail race held in the same place,
a 4K trek for walking together as a family
is new this year.

We put this together from
Pocheon City’s press releases (October 1 and 7)
and the notices on the race website.

🎪 What kind of event is it?

Its full name is ‘Hantangang Stone Festival (Festa)
with the Geopark Partners’.
The Hantangang UNESCO Global Geopark hosts it,
and Pocheon, Yeoncheon and Cheorwon run it together.

It’s a hands-on geology program
that uses Hantan River stones
to explore how the geology, volcanic activity,
columnar joints and canyons were formed.
The idea is that you see, touch
and try things for yourself.

It’s held together with
the ‘2026 Hantangang Ultra Lake Trail’ race.

✨ What’s on, and when?

The Festa runs both days,
and the 4K trek is on the morning of Sunday the 18th.

The schedule on the race website
lists a ‘Geo Fair’ (지오페어) on both days.

There are 50 booths in all.

Whether you came to see Bidulginang Falls
or you’re running in the mountain race,
anyone can join in freely.
Costs and booking for each activity
aren’t in the notice yet.

🥾 Is the 4K trek still taking sign-ups?

As of October 7,
sign-ups are still open.
The 4K sign-up button on the race’s official
registration site (InTheTrail) is live,
and the geopark notice also says ‘now accepting’.

But it’s first come, first served,
so it closes as soon as the 400 spots fill.
There’s no set closing date.

Children under 14 sign up for the ‘under 14’ option
and guardians for the ‘4K general’ option —
each one separately.
The refund and cancellation deadline (October 5)
has already passed.

You have to pick up your bib number yourself
with your ID (no pickup on someone else’s behalf).

🚗 Getting there & parking

The venue is the multipurpose plaza
inside the Hantangang UNESCO Global Geopark.
The race website gives the address as
410-2 Daehoesan-ri, Yeongbuk-myeon, Pocheon,
and Pocheon City’s tourism page gives
410-3 Daehoesan-ri as the navigation address
for Bidulginang Falls.

The race website warns that
nearby car parks will be congested
because of the Geo Fair
and weekend tourists.

Getting in may take a while,
so they ask you to arrive with time to spare.

👨‍👩‍👧 Going with kids

The 4K has no time limit,
so you can walk at your kids’ pace.

Bring your bib number
and you get perks at nearby attractions
on both days, the 17th and 18th.

If you use these perks,
you can’t also get the local gift voucher refund.
