A Backpacker’s Guide to Cheap Jeju Island Travel

A Backpacker’s Guide to Cheap Jeju Island Travel

The bus pulls away from Jeju City Intercity Bus Terminal and the first thing you notice is the sea light. You paid ₩1,200 in cash and you already have a seat. That is the moment the car anxiety should evaporate. Jeju Island has a reputation for being nearly impossible without a rental vehicle. That reputation is wrong. It is based on outdated information and a habit of comparing Jeju to cities with subways. The bus network here is thorough, cheap, and purpose built for reaching the volcanic cones, coastal walks, and trailheads that make this island worth the flight. You just need to know which bus to take and when.

The central question this page answers is whether you can travel Jeju cheaply without a car. The answer is yes, with caveats. You will trade speed for cost. You will need to plan around bus schedules instead of driving on impulse. What you gain is a trip that costs less than ₩50,000 for transport across a full week and a rhythm that forces you to slow down and walk the coastline rather than rush past it. Let’s make it work.

Getting There: Flights Over the Ferry

Jeju Air, Jin Air, T’way, Air Busan, and Korean Air all fly from Seoul Gimpo to Jeju. The route carried 13,560,000 passengers in 2023. OAG ranked it the world’s busiest domestic route. A flight takes 65 to 70 minutes. The one way fare ranges from ₩20,000 to ₩120,000. The cheapest booking window is 6 to 8 weeks before departure. This is the only way to arrive. Skip the ferry. The ferry from Busan takes over 11 hours, costs more than a budget flight, and arrives at a port that is inconveniently far from Jeju City’s bus station. The ferry makes sense only if you are bringing a car, which you are not, so book the flight.

Set a price alert on Jeju Air and Jin Air for your dates. When you see a one way fare under ₩40,000, buy it. Do not wait for ₩20,000. Those seats exist but they vanish within moments of release. Budget for ₩50,000 each way and consider anything less a win. Arrive at Gimpo 90 minutes before departure. The security line for domestic flights is short but the gate can be a walk.

The Bus Network: Red, Blue, and Green

The Jeju Special Self Governing Province runs the bus system. There are three types. Express buses are red. They run long distances on main roads with few stops. Trunk buses are blue. They connect towns and major tourist zones with more stops than express routes. Branch buses are green. They feed into the trunk and express lines and reach smaller villages, trailheads, and coastal paths.

Express Route 101: Jeju City to Seogwipo

This is the bus you take when you are moving between the island’s two main cities. Route 101 runs from Jeju City Intercity Bus Terminal to Seogwipo via the south coast. The ride takes about 80 minutes. The fare with a T money card is ₩1,850 to ₩2,850 depending on distance. Paying cash costs ₩2,000 to ₩3,000. Carry exact change. The driver gives no change. Buy a T money card at any convenience store. Load it with enough to cover multiple inter city trips and all your local travel.

Trunk Route 202: West Coast Attractions

Route 202 runs from Jeju City to Seogwipo via the west coast. It is slower than the 101 but it passes through Hallim Park, Hyeopjae Beach, and the O’Sulloc Tea Museum. If you are heading to the west coast attractions this is your line. The fare works the same as the express lines. T money is cheaper than cash.

Coastal Buses and Key Stops

Branch buses run along the coastal roads and stop at trailheads for the Olle trails and the Hallasan non summit hikes. Route 700 runs the full east coast loop from Jeju City past Seongsan Ilchulbong to Seogwipo. It takes about two hours and costs under ₩3,000. Hop off at Seongsan Ilchulbong, hike the crater, and catch the next bus heading south. Buses run every 20 to 40 minutes on major routes. The frequency drops on branch lines. Check the Jeju Bus Information app for real time arrivals.

Free and Cheap Sights Reachable by Bus

Jeju’s best attractions cost very little or nothing. The price of admission proves that the island was not designed exclusively for package tourists.

Seongsan Ilchulbong

UNESCO listed Sunrise Peak is a 182 meter volcanic tuff cone. The admission fee in 2025 was ₩2,000 for an individual. A group of ten or more pays ₩1,600 each. Open 07:00 to 20:00 in summer and 07:30 to 19:00 in winter. Take bus 700 from Jeju City Intercity Bus Terminal. It drops you about 500 meters from the entrance. Arrive by 08:30 to beat the package tour crowds. The hike up the stairway takes 20 to 25 minutes. The view is identical to the expensive helicopter tour. Skip the helicopter.

Hallasan Non Summit Trails

You can hike Hallasan without a summit reservation. The non summit trails are Eorimok (4.7 km), Yeongsil (3.7 km), and Donnaeko (7 km). No reservation is required. The summit trails Seongpanak and Gwaneumsa cap daily visitors and require a free reservation released one month in advance at 09:00 KST. The non summit trails give you the same volcanic landscape and the same views of the crater rim above the tree line for free. Take a bus from Jeju City to the Eorimok trailhead or to the Yeongsil trailhead. Bring water and snacks. There are no shops on the trail.

Olle Trails

27 routes covering 437 km. Route 7 starts in Seogwipo, runs 13.8 km along the coast and over an oreum, and ends near the sea. The Jeju Olle Foundation sells a passport for ₩20,000 that you stamp at the start, midpoint, and end of each route. The passport is a souvenir, not a requirement. You can walk any section for free. The coastal walks are where Jeju reveals itself. You get cliffs, basalt shorelines, and the sound of the sea without a ticket or a queue. Take a branch bus to the nearest trailhead marked on the Jeju Olle map and walk until you are tired. Then catch the next bus back.

Seafood Markets

Dongmun Market in Jeju City is the main seafood market. Arrive before 10:00 for the freshest catch. A bowl of hoe (raw fish) with banchan costs about ₩10,000 to ₩15,000. Grilled mackerel and a bowl of rice runs around ₩8,000. You do not need a restaurant reservation. Walk the aisles, point at what looks good, and eat standing at one of the shared tables. The market is a short walk from Jeju City Intercity Bus Terminal. The best budget meal on the island is here.

Budget Accommodation Without a Car

The guesthouse dormitory bed in Jeju City costs ₩15,000 to ₩25,000 per night in 2025. That is the cheapest option. The dormitories cluster around the bus terminal and the airport area. You walk everywhere. No ride share needed. A minbak room in a coastal area costs ₩30,000 to ₩50,000. These are family run guesthouses with private rooms and a small kitchen. If you are Muslim and need to self cater, book a minbak with the kitchen filter on Booking.com. Bring halal certified meat from Seoul. E mart Yongsan has a KMF certified halal section. There is no halal certified restaurant on Jeju. The Korea Muslim Federation database lists zero certified restaurants for 2025. Three restaurants self declare as Muslim friendly: Makan Halal Korean Restaurant in Jeju City, Bagdad Café in Jeju City, and Halal Korean Food in Seogwipo. None hold KMF certification. The Jeju Islamic Center in Nohyeong dong has a musalla but no KMF certification. There is no permanent prayer facility in Seogwipo.

Honest Caveat

This approach works only if you accept the trade off. You will not visit all 27 Olle trails. You will not catch sunrise at Seongsan Ilchulbong unless you are willing to leave Jeju City by bus at 05:00. You will miss the isolated beaches that require a long walk from the nearest bus stop. The bus network covers the major sights but it rewards patience over efficiency. The people who love Jeju without a car are the people who planned one hike per day and let the bus schedule decide the rest. The people who hate it are the people who tried to see the whole island in three days. Pick your pace. Spend the money you saved on a second bowl of hoe at Dongmun Market.
