Bangkok’s mass transit system moves over 2 million passengers daily across three rail networks: the BTS Skytrain, MRT subway, and Airport Rail Link. These elevated and underground trains are the fastest way to navigate Bangkok’s traffic, connecting major shopping districts, tourist attractions, business areas, and both airports. A single trip costs 16-62 THB ($0.45-1.75 USD) — far cheaper and faster than taxis during rush hour.

BTS Skytrain
The BTS (Bangkok Mass Transit System) is an elevated railway running above Bangkok’s busiest roads. It’s the most useful transit line for tourists, connecting Siam Square, Silom, Sukhumvit, Chatuchak, and the riverside areas.
Sukhumvit Line (Light Green)
Runs north-south from Khu Khot in the northern suburbs through central Bangkok to Kheha in Samut Prakan. Key stations for tourists:
- Mo Chit (N8) — Chatuchak Weekend Market, the world’s largest outdoor market
- Saphan Khwai (N7) — Local street food area, Chatuchak Park
- Siam (CEN) — Interchange station. Siam Paragon, MBK Center, Siam Discovery
- Nana (E3) — Bumrungrad Hospital, Sukhumvit nightlife
- Asok (E4) — Interchange to MRT Sukhumvit. Terminal 21 mall
- Phrom Phong (E5) — Emporium/EmQuartier malls, Benchasiri Park
- Thong Lo (E6) — Trendy restaurants, bars, cafes
- Ekkamai (E7) — Eastern Bus Terminal (buses to Pattaya, Koh Chang)
- On Nut (E9) — Budget accommodation area, Lotus’s
Silom Line (Dark Green)
Runs from National Stadium through Siam (interchange with Sukhumvit Line) to Bang Wa in the west. Key stations:
- National Stadium (W1) — MBK Center, Jim Thompson House
- Ratchadamri (S1) — Erawan Shrine, Central World
- Sala Daeng (S2) — Interchange to MRT Si Lom. Patpong Night Market, Lumpini Park
- Saphan Taksin (S6) — Chao Phraya Express Boat pier (access to Grand Palace, Wat Arun, Wat Pho)
- Krung Thon Buri (S7) — ICONSIAM shuttle boat
Tip: To reach the Grand Palace, Wat Pho, and Wat Arun, take the BTS to Saphan Taksin and catch the Chao Phraya Express Boat upriver. It’s cheaper and more scenic than a taxi through Old Town traffic.
MRT (Mass Rapid Transit)
Blue Line
The MRT Blue Line operates as a loop connecting areas the BTS doesn’t reach, including Chinatown, the old city (Rattanakosin), and Hua Lamphong railway station. Key stations:
- Chatuchak Park — Interchange to BTS Mo Chit. Chatuchak Weekend Market
- Sukhumvit — Interchange to BTS Asok. Terminal 21
- Si Lom — Interchange to BTS Sala Daeng. Silom business district
- Hua Lamphong — Bangkok’s main railway station (Hua Lamphong terminus)
- Wat Mangkon — Chinatown (Yaowarat Road). Best station for street food
- Sanam Chai — Wat Pho, Grand Palace (10-minute walk), Museum of Siam
- Itsaraphap — Closest to Wat Arun (short walk + ferry)
- Bang Sue — Krung Thep Aphiwat Central Terminal (new main railway station for long-distance trains)
Yellow Line (Opened June 2023)
The Yellow Line is a monorail running 30 km from Lat Phrao (interchange with MRT Blue Line) east and south to Samrong (interchange with BTS Sukhumvit Line extension). It connects Bangkok’s eastern suburbs with both the BTS and MRT networks. Most useful for residents rather than tourists, but it provides a useful connection between the MRT and BTS without going through central Bangkok.
Pink Line (Opened November 2023)
The Pink Line is a monorail running 34 km from Khae Rai (Nonthaburi, near MRT Purple Line) to Min Buri in eastern Bangkok. It passes through the government complex area and Muang Thong Thani. Like the Yellow Line, it primarily serves suburban commuters, but it does connect to the IMPACT Exhibition Center (Muang Thong Thani station).
SRT Red Line (Opened 2021)
The SRT Red Line is a commuter rail service connecting Krung Thep Aphiwat Central Terminal (Bang Sue) to the northern suburbs. The Dark Red Line runs 26 km north to Rangsit via Don Mueang Airport station — making it the only rail link to Don Mueang. The Light Red Line runs 15 km west to Taling Chan. Fares are 12-42 THB and trains run every 12-20 minutes from approximately 5:30 AM to midnight.
Airport Rail Link (ARL)
The Airport Rail Link connects Suvarnabhumi Airport to central Bangkok in approximately 30 minutes. The line runs from Suvarnabhumi Airport to Phaya Thai station (interchange with BTS) with 6 intermediate stops.
- Fare: 15-45 THB depending on distance (airport to Phaya Thai: 45 THB)
- Frequency: Every 10-15 minutes
- Hours: 5:30 AM – midnight
- Key interchange: Makkasan station connects to MRT Phetchaburi
The ARL operates a single city line stopping at all stations. The former Express service (non-stop airport to Makkasan) was discontinued — all trains now stop at every station.
Tip: For Don Mueang Airport (used by AirAsia, Nok Air, and other budget carriers), take the SRT Red Line from Krung Thep Aphiwat Central Terminal (accessible via MRT Blue Line at Bang Sue) to Don Mueang station — about 25 minutes, 12-42 THB. Bus A1 from Mo Chit BTS (30 THB) is another option. A free shuttle also runs between Don Mueang and Suvarnabhumi if you have a connecting flight.
Fares and Tickets
Single Journey Tokens
Buy at station ticket machines using coins or banknotes. BTS machines accept coins and small bills; MRT machines accept coins and up to 1,000 THB notes. Fares are 16-62 THB based on the number of stations traveled.
Rabbit Card (BTS)
The Rabbit card is a reloadable stored-value card for the BTS Skytrain. Cost: 200 THB (100 THB deposit + 100 THB credit). Reload at any BTS station or 7-Eleven. The Rabbit card also works at many shops, restaurants, and vending machines. It does NOT work on MRT or ARL.
MRT Stored Value Card
Separate stored-value card for MRT lines. Cost: 180 THB (80 THB deposit + 100 THB credit). Available at MRT station ticket offices. Does NOT work on BTS.
One-Day Pass
BTS offers a one-day unlimited ride pass for 140 THB — worth it if you plan to make 4+ trips in one day. MRT does not currently offer a tourist day pass.
Important: BTS and MRT use separate ticketing systems. A Rabbit card won’t work on MRT, and vice versa. If you’re transferring between systems, you’ll need to tap out and buy a new ticket or use the other system’s card. There is no single card that works across all Bangkok transit networks.

Practical Tips
- Avoid rush hour — 7:30-9:00 AM and 5:00-7:00 PM. Trains are extremely crowded, especially at Siam, Asok, and Mo Chit stations.
- Stand right on escalators — Keep left clear for people walking. This is enforced by social convention.
- No eating or drinking — Food and beverages are prohibited on all trains and station platforms. Fines apply.
- Air conditioning is strong — Trains and stations are heavily air-conditioned. Carry a light layer if you’re sensitive to cold.
- Last train is around midnight — Plan accordingly. After midnight, you’ll need a taxi or Grab.
- Use Google Maps — Bangkok transit is well-mapped in Google Maps. It shows real-time train schedules and walking transfers between BTS and MRT stations.
- Grab/Bolt for the last mile — Many attractions are a 5-15 minute walk from the nearest station. Use ride-hailing apps for short hops — they’re cheap (40-60 THB for short trips).
Other Public Transport
Chao Phraya Express Boat
River boats run along the Chao Phraya River connecting many riverside attractions. Board at Sathorn Pier (BTS Saphan Taksin). The orange-flag boat (15 THB flat fare) runs most frequently. Tourist boats (blue flag, 60 THB) have audio commentary. Boats run approximately 6:00 AM – 7:00 PM.
Khlong Boats (Canal Boats)
The Khlong Saen Saep Express Boat runs east-west along Bangkok’s main canal, connecting the Golden Mount area to Pratunam and on to Ramkhamhaeng. Fare: 10-20 THB. Fast and cheap but can be crowded and wet (water splashes in during the ride).
Buses
Bangkok’s bus network is extensive but confusing for visitors. Air-conditioned buses cost 12-25 THB. The ViaBus app shows real-time bus locations. Useful routes: A1/A2 from Don Mueang Airport to Mo Chit BTS, and route 556 from Don Mueang to Khao San Road.
Frequently Asked Questions
What’s the cheapest way to get from Suvarnabhumi Airport to central Bangkok?
The Airport Rail Link (ARL) at 45 THB to Phaya Thai is the cheapest option. From Phaya Thai, transfer to the BTS Skytrain (16-44 THB) to reach your destination. The total cost is under 90 THB ($2.50 USD). A taxi costs 300-500 THB depending on traffic, plus 50 THB airport surcharge and expressway tolls.
Can I use one card for both BTS and MRT?
No. The BTS Rabbit card and MRT stored-value card are separate systems. You need a different card (or buy single-journey tokens) for each network. When transferring between BTS and MRT, you’ll exit one system and enter the other at interchange stations like Asok/Sukhumvit, Sala Daeng/Si Lom, or Mo Chit/Chatuchak Park.
How do I get to Don Mueang Airport by train?
Take the SRT Red Line from Krung Thep Aphiwat Central Terminal (accessible via MRT Blue Line at Bang Sue). The ride takes about 25 minutes and costs 12-42 THB. Don Mueang station is a short walk from the terminal. Alternatively, bus A1 from Mo Chit BTS (30 THB, every 10-15 minutes) or a taxi from central Bangkok (200-350 THB) also work. A free shuttle bus runs between Suvarnabhumi and Don Mueang airports if you have a connecting flight.
Is Bangkok’s train system safe to use at night?
Yes. BTS and MRT stations are well-lit, have CCTV cameras, and security guards are present at all stations. The trains run until approximately midnight. After midnight, use Grab or Bolt (ride-hailing apps) rather than hailing taxis on the street.
What’s the best transit option for getting around Bangkok as a tourist?
For most tourists, a combination of BTS Skytrain and MRT covers the main attractions. Buy a Rabbit card for BTS and single-journey tokens for MRT. Use the Chao Phraya Express Boat to reach riverside attractions (Grand Palace, Wat Arun). For areas not covered by rail, use Grab or Bolt. Tuk-tuks and motorcycle taxis are options for short distances but negotiate prices first.
