02More about the top three

The ranking is above. Here is more about the three places at the top: what they are, why they are here, and what is worth knowing.

The three are compared on different ferry measures: winter stoppage days, no regular ferry at all, and a normal crossing time.

1Ulleungdo Lighthouse

No. 1 — Ulleungdo Lighthouse. On the lists of 8 of 10 AIs; median place there: 4. The AIs liked its dramatic volcanic scenery and trails, but winter ferry stops and a long crossing hold it back.

Did you know

  • Ulleungdo Lighthouse sits on a cliff and is described as the first staffed lighthouse in Ulleung County. Nearby you can also see Daepungam, the Hyangmok Observatory and Elephant Rock.

    Source ↗
What it is
A volcanic island with many trails and a cliff-top lighthouse.
Its edge
Has a real ferry route and the most to see on land.
Who it suits
Suits hikers with flexible dates; not people on a tight schedule.
  • Ferry access reliabilityFerries halt 15–20 days (Dec)
Why it is here

  • A reported plan would leave all 6 ferries serving Ulleung stopped for 15 days in December 2025. That risk of being cut off weighs on trip planning, even for an island with many walking trails. — (voice only)

    Source ↗
History

  • In 1979, more fishing boats near Ulleungdo led to the lighthouse being changed from unmanned to manned. The shift marked its growing role in guiding boats in the area. — (voice only)

    Source ↗
Keep in mind

  • The Pohang–Ulleungdo ferry takes about six hours overnight. Dokdo tours take about four hours round trip, with roughly 30 minutes on the islets if weather allows landing. Rough waves can delay or cancel sailings.

    Source ↗
Where to go further

  • Start with Daepunggam (Taeha) Lighthouse on the northwest tip: a 20 m tower built in 2011. Then look at Malpbawi, a 19 m lighthouse reached only by boat.

2North Gyeokryeolbi Island Lighthouse

No. 2 — North Gyeokryeolbi Island Lighthouse. On the lists of 8 of 10 AIs; median place there: 5.5. The AIs split on it: famous as the 'Dokdo of the West Sea' with a concert, but no regular ferry runs.

Did you know

  • The tower is only 9.7 m tall, but it stands on a 107 m summit. Its light can be seen from 35 to 40 km away.

    Source ↗
What it is
A remote lighthouse island about 55 km out in the Yellow Sea.
Its edge
The most remote and unusual of the three, with a concert tie-in.
Who it suits
Suits people who like the story; not anyone who wants to actually visit.
  • Ferry access reliabilityNo regular ferry; 55 km
Why it is here

  • The lighthouse was first lit in 1909 and became a staffed lighthouse again on July 1, 2015. Its long history gives the isolated setting a distinctive draw, even though it is not a regular passenger-ferry destination. — (voice only)

    Source ↗
Did you know

  • The lighthouse was first lit in June 1909. Its old lenses, each about 116 cm tall, were used until recently. Four of them are now shown in the National Lighthouse Museum in Pohang.

    Source ↗
History

  • In 1994, harsh living conditions on this remote island led to the lighthouse becoming unmanned. It returned to manned operation in 2015, after agencies concluded regular staffing was needed. — (voice only)

  • Ferry access reliability~2½-hour ferry from Mokpo
Why it is here

4What we looked at

  • Compare ferry operations and passenger counts with reported visits to individual tourist sites.
  • Judge each island’s concert-trip potential by access, visitor interest, weather exposure, remoteness, and the appeal of its setting.
  • Korea Maritime Transportation Safety Authority, via Korea’s Public Data Portal — Monthly passenger-ship operations by departure port, including planned and actual sailings, passengers carried, and wea

  3. 3
    Dokdo (Dongdo Lighthouse)

    A high-stakes patriotic pilgrimage 87 km east of Ulleungdo, where East Sea swell prevents ferries from berthing 25% to 30% of the time, forcing live sets to double as maritime cliff maneuvers.

    Udo Island (우도), Jeju, South Korea

    One island, three published visitor counts for the same period — 500,064, 530,000 and 2.59 million — because nobody counts an island the same way twice.

  2. 2
