Jeju City to Tongyeong: A Scenic, Ferry-Backed Road Trip Guide

Jeju City sits at the northeast corner of Jeju Island, while Tongyeong anchors the southern coast of the Korean mainland. The shortest route between them requires a 108-km drive on Jeju's expressways (Route 1135 and 1115) to the port at Seongsan or Jeju City, followed by a 2.5-hour car ferry to Wando, then a 90-minute drive on National Route 13 and the Namhae Expressway Branch to Tongyeong. The entire journey spans roughly 380 km of road and sea, with a total travel time of 6 to 7 hours excluding ferry wait times.

The route is unique for its dual-modal nature, crossing the Jeju Strait, a body of water known for its strong currents. Ferries operate year-round, but schedules are subject to weather; the most reliable crossings depart from Seongsan Port (34.0°N, 126.9°E) to Wando (34.3°N, 126.7°E).

Driving on Jeju Island is straightforward: roads are well-paved, and navigation via Naver or Kakao Maps is reliable. Fuel costs on Jeju are notably higher than on the mainland—about 1,200 KRW per liter for gasoline versus 1,100 KRW on the mainland—so consider filling up after docking in Wando. Along the mainland leg, highway rest areas every 30-40 km provide fuel, food, and restrooms; notable stops include the Hadong Rest Area on the Namhae Expressway.

• All major routes are toll-free on Jeju; the mainland's Namhae Expressway Branch has a toll of about 5,000 KRW for a standard car.
• Rental cars on Jeju must be returned before the ferry; the ferry does not carry rental vehicles. If you need a car in Tongyeong, consider a one-way rental with drop-off.
• Parking at Seongsan Port is ample, with long-term lots costing 10,000-15,000 KRW per day.
• For real-time ferry schedules and reservations, use the Wando Ferry Terminal website or app.

For planning the best stops along any road trip, tools like how to find the best stops and hidden gems between cities can be invaluable. Always book ferry tickets in advance during peak seasons (July-August and Korean holidays) to avoid sold-out sailings.

Both Jeju and mainland routes have excellent safety records. On Jeju, watch for free-ranging horses near Hallim Park (33.2°N, 126.3°E) and occasional fog on the expressway. On land, the Namhae Expressway is well-lit and signposted in Korean and English. The Hallyeohaesang tunnel, at 290 meters, is the only submerged tunnel in Korea and adds a brief underwater thrill.

For families, the route is highly suitable. Jeju offers the Teddy Bear Museum and the Jeju Stone Park, while Wando has a sand dune beach at the nearby island of Bogil-do that suits small children. In Tongyeong, the Sanyang Beach and the maritime cable car appeal to all ages. Food stops along the way consistently provide highchairs and children's menus; consider the Hadong Rest Area's food court, which includes a dedicated kids' zone with play equipment.

To manage fatigue during the drive, plan a break every 2 hours. On the sea crossing, take a walk on the deck. On land, rest areas like the Jinju Rest Area on the Namhae Expressway offer walking paths and quiet lounges. After the ferry, the drive to Tongyeong is relatively straight and easy, but ensure you stay hydrated and avoid driving during the post-lunch dip (1-3 PM) if you can stop for a short rest. Pet-friendly infrastructure is expanding, but note that ferries to Wando do not allow pets except service animals; plan accordingly by booking a ferry that permits pets (some do on a limited basis) or leaving pets at a trusted facility.

The route's landscapes shift dramatically: Jeju's volcanic basalt fields and UNESCO-listed Geomunoreum Lava Tube system give way to the scenic islands of the Hallyeohaesang National Park as you approach Tongyeong. On the Jeju side, don't miss the Seongsan Ilchulbong, a tuff cone crater that is also a UNESCO World Heritage Site, rising 182 meters above the sea. The short hike to its rim takes about 30 minutes and rewards with 360-degree views of the coast.

In Wando, a quick detour to the Wando Arboretum offers a walk among camellia and fir trees—a peaceful break before returning to the car. Along the mainland leg, the drive parallels the southern coast, with the distinct shape of Mireuk Island visible in Tongyeong's harbor. This island hosts a cable car that ascends to Mireuksan Mountain, providing panoramic views over the 63 islands of the Hallyeo Marine National Park.

Local commerce thrives on this route: Jeju's famous hallabong oranges are sold at roadside stands near Seongsan, and Wando's seagull-shaped bread, galchi (hairtail) specialties, and green tea products make memorably tasty purchases. Tongyeong is renowned for its honey bread (kkulppang) and the bustling Jungang Market, where you can sample fresh raw fish and dried seafood.
