Getting around Busan is easy once you understand the system, and it’s one of the cheapest, most reliable ways to see the city. The metro is clean, frequent and fully signed in English, the buses fill in the gaps, and a single tap-and-go transit card covers all of it. This guide explains the four subway lines and what they reach, which card to buy and how, how to actually ride and transfer step by step, fares and day passes, the buses, and the two extra rail lines (to the airport and the east coast). For getting from the airport into the city specifically, see our airport guide; for the rest of your trip, see our complete Busan Travel Guide.

1. Busan’s public transport at a glance

Busan’s network is bigger than first-timers expect, and almost all of it is English-friendly:

• Metro (subway), Lines 1–4 — the backbone, reaching downtown, the beaches, the markets and more.
• Busan–Gimhae Light Rail (BGL) — the elevated line that serves Gimhae Airport.
• Donghae Line — a commuter rail along the east coast to Songjeong, Osiria (for Haedong Yonggungsa) and beyond.
• City buses — they cover the hills and corners the metro misses, including the way to some big sights.

One transit card works across all of them. Pair it with a maps app and you can reach almost everywhere a visitor wants to go.

2. The metro lines & what they reach

Four numbered lines, each a color, cover the city. Here’s what matters to a visitor:

For most trips you’ll live on Lines 1 and 2: Line 1 runs north–south through the old downtown (Busan Station, Nampo, Seomyeon), and Line 2 curves east along the coast to the beaches (Gwangalli, Haeundae). They cross at Seomyeon, the central hub.

3. Transit cards — get one first

Before your first ride, buy a rechargeable transit card. Tap it boarding and exiting and you get a small fare discount plus free or cheap transfers — and you never queue for tickets.

1. Buy the card At any convenience store (CU, GS25, 7-Eleven) or a station machine — a few thousand won for the blank card.
2. Load cash onto it Ask the cashier to top it up, or use a charging machine in any station (cash).
3. Use it everywhere Tap on metro, buses and many taxis, and even to pay at convenience stores.

4. How to ride the metro, step by step

The first ride is the only one that feels unfamiliar. Here’s the whole flow:

1. Find your route In KakaoMap/Naver Map, search your destination and pick transit — it tells you the line, the direction and which exit to use.
2. Enter & tap in Tap your transit card on the gate reader (or buy a single-journey ticket from the machine — English available — if you have no card).
3. Find the right platform Follow signs for your line (by color and number) and the direction — platforms are marked with the terminal station name, so know which end you’re heading toward.
4. Ride & count stops Stations are announced and displayed in English; screens show the next stop and transfers.
5. Transfer if needed Follow the colored signs to the other line — you stay inside the gates, so no extra tap for a metro-to-metro change.
6. Tap out Tap your card again at the exit gate (fares are distance-based, so you must tap out). Then follow your exit number to the street.

5. Fares, transfers & day passes

Busan’s metro is distance-based and cheap. Approximate adult fares (always confirm current prices — they change):

• Transfers: with a transit card you get a discounted/free transfer between metro and bus (different route) within about 30 minutes, up to twice per trip — a big saving on mixed journeys.
• Day pass caveat: the metro day pass covers the subway only — not buses, the Donghae Line or the airport light rail. For mixed travel, a topped-up transit card is usually better value.

6. Buses — for everywhere the metro doesn’t reach

Some big sights (like Taejongdae and Haedong Yonggungsa) need a bus for the last stretch. Buses are easy with a card and a maps app:

• Types: regular city buses, faster express buses (red, fewer stops), and small village (maeul) buses for the hilly neighborhoods.
• Paying: tap your transit card boarding (and tap off on some routes); cash is accepted but a card is cheaper and gives transfers.
• Finding the stop: let KakaoMap/Naver Map tell you the exact stop and the live arrival — bus numbers and stops are hard to guess otherwise.

7. The light rail (airport) & Donghae Line (east coast)

Two extra rail lines fill in where the metro stops, and visitors use both:

Busan–Gimhae Light Rail (BGL)

The elevated light rail that connects to Gimhae International Airport, linking it to Metro Lines 2 and 3. It’s the rail option to and from the airport — see our dedicated airport guide for the full comparison with the limousine bus and taxis.

Donghae Line

A commuter train running up the east coast, useful for visitors heading to Songjeong Beach, Osiria (the stop for Haedong Yonggungsa and the resort area) and beyond. It connects with the metro at a few stations.

8. Tips, etiquette & the bottom line

A few final pointers for smooth riding:

• Rush hour: roughly 8–9am and 6–7pm are busy; trains are frequent so just wait for the next one if it’s packed.
• Last trains: the metro stops around midnight — check the last-train time in your maps app or the Subway Korea app if you’re out late.
• Etiquette: leave the pink/marked priority seats for the elderly, pregnant and disabled; keep calls quiet; line up at the platform markings.
• English: signs, maps and announcements are all in English, so you really can’t get too lost.

That’s the whole system. Plan your days and stops with our complete Busan Travel Guide.
