Tongyeong Passenger Ferry Terminal is a major island gateway at 234 Tongyeonghaean-ro. Reference information lists routes serving islands such as Hansando, Bijindo, Somaemuldo and Yokjido, but route patterns and vessels can change, so treat those as orientation rather than a permanent timetable.
Before you travel, identify the exact island and landing point, then confirm which operator and sailing you are actually booked on. On the day of travel, use KOMSA's passenger-ferry operation information to check whether the sailing is operating, cancelled, delayed or under review. KOMSA explicitly warns that forecast status can still change and that passengers should confirm operation on the travel day.
For a same-day island trip, check the return sailing before boarding the outbound ferry. Do not assume that the last return is late enough for a long hike or beach visit. If weather is marginal, keep the city-side part of your itinerary flexible.
Bring the identification required for domestic ferry boarding and arrive with enough time for ticket and boarding procedures. Operator-specific ticket, vehicle and baggage rules should be checked with the actual carrier rather than generalized from another route.
