This post is less a review
than a record.
All we kept were
the submarine booking confirmation,
the timestamps on our photos,
and a one-line review
we left for a hairtail restaurant.
We never noted down
the tastes or what the kids said,
so we leave those out
and add the official
Udo Submarine information instead.
🚗 May 1, by ferry from Nokdong
On day one we loaded our car
onto the ferry at Nokdong Port
in Goheung, South Jeolla,
and arrived at Jeju Port.
We have no photos
from after we got off the ship,
so we leave the rest of that day out.
🌊 May 2, 12:45 — Udo Submarine
The heart of day two
was the Udo Submarine.
We booked it on Naver on April 29,
and the confirmed sailing was
Saturday, May 2 at 12:45 pm.
The product name said
“[Early-bird] special price!!”,
and the confirmed total was
140,000 won.
The confirmation screen
didn’t say how many people
that covered, so we stop there.
We have no photos from inside
the submarine or under the sea.
So here is only
what the official site says
(checked September 2026).
at Seongsan Port, not on Udo!
Be at the terminal ticket office
20 minutes before sailing
Where to board
Seongsan Port Ferry Terminal,
submarine ticket office inside —
fill in a boarding form, then get tickets
The route
Seongsan Port → the dive → Seongsan Port
It’s not a ride you take
after going over to Udo
The submarine
Yonggung No. 51, up to 54 people
12 viewing windows on each side
coral colonies at 30 m, a feeding show
and an “undersea wine” performance
(as the official info describes it)
ID
Every passenger brings an original ID —
children need a document too,
such as a passport
Weather and cancellations
It sails in the rain,
but swells and sea conditions
can stop it — check that morning!
Cancel the day before: full refund;
same-day cancellation or no-show: no refund
The current official base timetable
09:45 · 10:30 · 11:15
13:30 · 14:15 · 15:00
doesn’t include the 12:45 sailing
we booked.
The site says sailings change
with sea weather and minimum passenger numbers,
so go by the times
on your booking screen.
📸 15:48 — Udo’s white stairs
Our next record after the submarine
is 3:48 pm, on Udo island.
We took our car
over to Udo by ferry, too.
On black basalt rocks
stands a single white staircase
leading up into the sky,
with ‘우도 비양 카페’ (Udo Biyang Cafe)
on the front.
Udo — the white-stair photo spot marked '우도 비양 카페' (Udo Biyang Cafe), with basalt rocks and the sea beyond
The sky was overcast that day.
The kids spread their arms
at the top of the stairs,
and we took eight photos
in two minutes —
all of them show faces,
so we only share
the bottom of the stairs.
We have no record
of where else we went on Udo.
🐟 Evening — Seongsan Bada Punggyeong
Dinner that night was in Seongsan, at
Seongsan Bada Punggyeong (성산바다풍경), Seongsan Ilchulbong branch.
The one-line review we left on Naver:
good value, fast turnover,
tasty, and
”the free whole hairtail was the best!!!”
For keywords we picked
’generous portions’,
‘good side dishes’
and ‘fresh ingredients’.
📍 Seongsan Bada Punggyeong (성산바다풍경) — open in Naver Map
Banner — order braised fish, get a whole grilled hairtail free; large-small 39,000 · large-medium 59,000 · large-large 79,000
The wall banner (when we visited, May 2026) said:
“Order braised fish, and
a whole grilled hairtail is free”
Bada Punggyeong braised fish
large-small 39,000 won (small hairtail)
large-medium 59,000 won (medium)
large-large 79,000 won (large)
“Order by how hungry you are,
not by the number of people” —
four people who aren’t very hungry
can pick small or medium,
two hungry people medium or large.
Second banner — hot pot, obunjagi hot pot and whole grilled Jeju hairtail; the LED clock on the left reads 19:44
Bada Punggyeong ttukbaegi (hot pot) 16,000 won
Obunjagi (small Jeju abalone) ttukbaegi 19,000 won
(only when the haenyeo divers are working)
Whole Jeju hairtail, grilled
small 28,000 · medium 38,000 · large 48,000 won
Extra side dishes are self-service,
and the origin labels end with
”Owner — product of Jeju”.
Since our review says
the free whole hairtail was the best,
we read it as: we ordered braised fish
and got the free hairtail.
We have no photo
of which size we ordered.
The wall clock read 7:44 pm.
📅 May 3
Not a single photo from this day.
With no record, we leave it blank.
⛴ May 4, leaving Jeju
The last day’s record is
six minutes from 4:38 pm
on the deck of a ferry leaving Jeju Port.
The deck floor is all blue,
and among a thatched-house and Hallasan sculpture,
a dol hareubang (stone grandfather)
and a tangerine sculpture
stands a JEJU letters photo zone.
Our family photos there all show faces,
so we leave them out.
4:44 pm — walking along the deck, Jeju Port and the city beyond the railing
From 4:42 pm we stood at the railing
and watched the sea.
As the ship cleared the breakwater,
the sun behind the clouds
lit the sea white.
The ferry home was
the Queen Jenuvia, Jeju Port to Mokpo,
with our car on board too.

All that’s left of our four days
is the afternoon of May 2
and the last day’s deck.
Still — the Udo Submarine
leaves from Seongsan Port
on a round trip back to Seongsan Port,
and Seongsan Bada Punggyeong’s braised fish
comes with a free whole grilled hairtail.
Those two things are useful right away
for whoever goes next, so we leave them here.
