Busan Public Transport Guide 2026: Subway, Bus, and Transport Cards Explained

TL;DR: Busan's public transport network in 2026 includes four subway lines, the Donghae Line, the Busan-Gimhae Light Rail, and an extensive color-coded bus system. Grab a T-Money, Cashbee, or Hanaro card at any convenience store for discounted fares and free transfers (up to two within 30 minutes). Use Naver Map or KakaoMap instead of Google Maps for accurate real-time arrival info. Metro fares start at 1,300 KRW for the first 10 km.

Busan is South Korea's second-largest city, stretching along the southeastern coast with beaches, mountains, temples, and markets spread across a wide area. While that sprawl might sound intimidating, the city's public transport system is one of the best in Asia. Subways, buses, and light rail connect virtually every neighborhood, and a single rechargeable card covers them all. Whether you are spending 3 days in Busan or a full 5-day itinerary, understanding the transport network will save you money, reduce stress, and open up parts of the city that most tourists never see. This 2026 guide covers every mode of transit, fare details, payment options, and practical tips you need to navigate Busan confidently.

Transport Cards: T-Money, Cashbee, and Hanaro

Before you ride anything in Busan, pick up a rechargeable transport card. Three major options work across the entire network:

• T-Money — The most widely recognized card in South Korea. Works on all Busan subways, buses, and even in taxis and convenience stores. Available at any CU, GS25, or 7-Eleven.
• Cashbee — Equally accepted throughout Busan and preferred by some locals. Also sold at convenience stores and subway station machines.
• Hanaro Card — Busan's official regional transit card. Provides the same transfer discounts and is rechargeable at Busan Bank branches, subway stations, and convenience stores.

All three cards cost around 2,500 KRW to purchase (non-refundable card fee). Load 10,000 to 20,000 KRW to start and top up at subway station machines or any convenience store. Using a card instead of cash gives you a discount on every ride and, crucially, enables free transfers — up to two transfers within 30 minutes of tapping off (extended to 60 minutes after 9:00 PM). Cash riders pay higher fares and receive no transfer discount. For budget planning, see our Busan travel budget tips.

Busan Subway: Lines, Fares, and Key Stations

Busan's metro is the backbone of the city's transit system. It runs daily from approximately 5:00 AM to midnight, with trains arriving every 4 to 8 minutes during peak hours. The network consists of six lines:

• Line 1 (Orange) — The oldest and most useful tourist line. Connects Nopo (north) to Sinpyeong (south), passing through Busan Station, Nampo-dong (for Jagalchi Market and BIFF Square), Seomyeon, and Dongnae (for Beomeosa Temple).
• Line 2 (Green) — Runs east-west from Jangsan to Yangsan. Essential for reaching Haeundae Beach, Gwangalli Beach, Centum City, and connects to Seomyeon (transfer with Line 1).
• Line 3 (Gold) — Links Sujeong to Daejeo. Useful for getting to Mandeok, Sports Complex, and connecting to Line 1 at Yeonsan.
• Line 4 (Blue) — A shorter automated line connecting Minam to Anpyeong. Less tourist-heavy but handy for residential eastern areas.
• Donghae Line (Sky Blue) — Connects Bujeon to Ilgwang and extends toward Ulsan. Perfect for reaching Gijang, Osiria (home to Lotte World Adventure Busan), and the eastern coastal area.
• Busan-Gimhae Light Rail (Purple) — The airport connector. Runs between Gimhae Airport and Sasang Station (where you transfer to Line 2). Essential for airport arrivals. For a full breakdown, see our Busan airport transportation guide.

Fares: Metro rides cost 1,300 KRW for the first 10 km with a transport card, plus 200 KRW per additional 10 km. Crossing the Busan-Ulsan boundary on the Donghae Line adds 200 KRW, with a maximum fare of 2,500 KRW. Cash single-use tickets cost 1,400 to 1,600 KRW depending on distance.

Station signage is displayed in Korean, English, Japanese, and Chinese, and train announcements are made in all four languages. Most stations have elevators, escalators, and barrier-free access.

Buses: Color Codes, Routes, and Practical Tips

Busan's bus network reaches areas the subway cannot, including cliffside villages, coastal parks, and mountainside temples. Buses are color-coded by route type:

• Blue buses — Major trunk routes connecting large districts across the city.
• Green buses — Neighborhood feeder routes linking residential areas to subway stations.
• Red buses — Express routes covering longer distances with fewer stops.
• Yellow buses — Circular routes within specific zones, useful for tourists exploring a concentrated area.

Tap your transport card when boarding (front door) and again when alighting (rear door) to register transfers correctly. If you forget to tap off, you will be charged the maximum fare and lose your transfer discount. Press the buzzer near the rear door before your stop to signal the driver.

Bus fares: Standard adult bus fare with a transport card is around 1,300 KRW for city buses and 1,800 KRW for express (red) buses. Cash fares are 100 to 200 KRW higher.

Navigation tip: Do not rely on Google Maps for Busan bus routes. Naver Map and KakaoMap provide accurate real-time bus locations, arrival countdowns, and route planning that Google Maps simply cannot match in South Korea. Download either app before you arrive.

Buses are especially important for reaching Gamcheon Culture Village (buses 1-1, 2, 2-2 from Toseong Station), Taejongdae Park, and Huinnyeoul Culture Village — all of which sit outside the subway's reach.

Mobile Passes and QR Tickets

If you prefer going cardless, Busan's metro system supports mobile payment options in 2026:

• Busan Subway App — Available on both Google Play and Apple App Store. Purchase mobile passes (1-day, 3-day, or 30-day commuter options) directly in the app and scan at turnstiles.
• QR single-use tickets — Available from ticket vending machines inside every metro station. Useful if you only need a one-off ride without buying a physical card.
• NFC-enabled phones — Some Android phones with Korean carrier SIMs can load T-Money directly onto the device.

For short visits (1 to 3 days), the day-pass options can save money if you plan more than four rides per day. A 1-day metro pass typically costs around 5,000 KRW. Not sure how long to stay? Our guide on how many days in Busan helps you decide the ideal trip length.

Taxis, Ride-Hailing, and Ferries

Public transport does not run 24 hours, so taxis fill the gap after midnight. Busan taxis are metered and reasonably priced — the base fare starts at approximately 4,800 KRW for the first 2 km. Ride-hailing through Kakao T is the most reliable method. The app supports English, shows fare estimates upfront, and allows card payment so you avoid cash disputes. Flagging taxis on the street also works, though communication can be difficult without Korean.

Busan also operates coastal ferries to nearby islands and between waterfront districts. The most popular tourist ferry runs between Songdo and Amnam Park, offering scenic ocean views. For day trips outside Busan, the KTX high-speed train from Busan Station reaches Seoul in under 2.5 hours, and regional trains connect to Gyeongju and other destinations.

Getting from the Airport to the City

Gimhae International Airport connects to central Busan via the Busan-Gimhae Light Rail. Take the light rail from the airport to Sasang Station, then transfer to Subway Line 2 toward Haeundae or Seomyeon. The entire journey to Seomyeon takes roughly 45 minutes and costs under 2,000 KRW with a transport card.

Airport limousine buses also run to Haeundae and other major hotel districts, costing around 7,000 KRW. Taxis from the airport to Seomyeon cost approximately 15,000 to 20,000 KRW, and to Haeundae around 30,000 KRW.

Insider Tips for Getting Around Busan in 2026

• Transfer timing matters. Your free transfer window is 30 minutes from the moment you tap off (60 minutes after 9 PM). Plan connections accordingly to avoid paying double.
• Avoid rush hours. Subway cars get packed between 7:30 to 9:00 AM and 5:30 to 7:30 PM on weekdays. If possible, shift your sightseeing schedule slightly outside these windows.
• Seomyeon is the hub. Lines 1 and 2 intersect here, making it the most important transfer station and a logical base area. Check our guide on where to stay in Busan for accommodation near key stations.
• Last train warning. Services end around midnight. If you are out late, check the last train time for your specific station in Naver Map. Missing it means a taxi ride.
• Keep your card loaded. Running out of balance at a turnstile is annoying. Maintain at least 5,000 KRW on your card to avoid delays.
• Accessibility. All subway stations have elevators and most buses have low-floor boarding. Busan is one of the more accessible cities in South Korea for wheelchair users and stroller-pushers.
