South Korea

Jeju

A volcanic island off Korea's south coast, centred on Mount Hallasan. No rail at all; the bus is how Jeju moves.

Island boats (dohangseon and yeogaekseon)

Every island boat is ticketed at the port desk: you fill in a boarding form and each adult shows an original photo ID. Marado has two ports and two operators, so you come back with the one you booked.

    Only electric or hydrogen rental cars cross to Udo

    A rental car whose garage is not registered on Udo cannot be carried across, and nor can a chartered coach or a rented petrol motorbike, moped or e-scooter. The exemption is for what the province calls a class 1 low-emission vehicle - electric or hydrogen - along with electric two-wheelers and 16-seat coaches; no notice puts a hybrid on that list. Cars carrying a disabled, elderly or infant passenger are also exempt. It is the vehicle that is stopped, not you - on foot you board normally. Ask at the port whether the car you hired counts as exempt.

How to ride

  1. 1
    Check which port you sail from
    Marado has two ports with different operators, Unjin and Songaksan. Udo sails from Seongsan or Jongdal, Biyangdo from Hallim.
  2. 2
    Reach the ticket desk 40 minutes before
    Unjin: pre-booked tickets 40 minutes before, all sales close 10 minutes before. Songaksan issues every ticket 30 minutes before.
  3. 3
    Hand in the boarding form and your ID
    Every adult needs an original photo ID such as a passport - a copy or an image stored on a phone is refused.
  4. 4
    Collect the ticket and board
    Collect the ticket at the desk and show it at the quay. Sailings are capacity-limited, so a full boat means the next one.
  5. 5
    Return on the same operator's boat
    A Marado return ticket is only valid with the operator you booked, and your time ashore is set by the sailing.

Heads-up

  • Copies and phone photos of ID are refused

    Ticketing needs a boarding form and an ID for every adult; for a visitor that means the physical passport. A copy, an image saved on a phone and a foreign driving licence that is not an international permit are all refused, while Korea's government mobile ID is accepted. The check is not the operator's discretion but a duty under the Shipping Act enforcement rules, so without it you do not sail.

  • Cancellations are decided on the morning

    Whether boats run is settled after 08:00 on the day itself, and rain is not a reason to cancel - wind speed and wave height are. On the day of a crossing, check the live status for the return leg as well before you set out.

  • Bicycles cannot be loaded at Unjin

    Boats from Unjin carry no adult bicycle, no kick scooter and no personal mobility device of any kind; children's bikes and scooters are allowed only if they are not electric. Songaksan takes a folding bicycle free as hand baggage, and for Udo you have to ask the operator in advance. Gapado cannot be reached with a bicycle at all; Marado only with a folding bike from Songaksan.
