Bangkok BTS Skytrain

The BTS Skytrain covers Bangkok’s tourist and commercial belt in two elevated green lines and one short connector. It reaches the shopping districts, the weekend market, the Silom nightlife strip, and the Chao Phraya piers. It does not cover the Grand Palace, Chinatown, or Khao San Road. Knowing that boundary before you board saves an expensive Grab ride in the wrong direction.

The Three Lines

The Sukhumvit Line runs from Mo Chit in the north down to Kheha in the southeast. This is the line most visitors use most often, passing through Siam, Asok, Phrom Phong, and On Nut.

The Silom Line runs from National Stadium to Bang Wa. It crosses the Sukhumvit Line at Siam station, a free interchange with no second tap required. The Silom Line covers the business district, Sala Daeng nightlife, and Saphan Taksin, the pier station for river access.

The Gold Line branches off the Silom Line at Krung Thon Buri and runs three stations to ICONSIAM and Khlong San on the riverside. It is operated by the same company as the Green Lines but ticketed separately. The Rabbit Card works on all three lines.

Fares and Tickets

Fares run from THB 17 to THB 65 per trip, calculated by distance. A One-Day Pass costs THB 150 and covers unlimited rides on the Green Lines; it expires at midnight on the day of purchase, not 24 hours from first use. The Bangkok Rabbit Card guide covers how to buy one, top up, and collect one at the airport.

Operating Hours

First trains leave terminal stations at 05:15 on the Sukhumvit Line and 05:30 on the Silom Line. Last trains depart central stations around midnight and reach the end of each line by approximately 00:45. The Gold Line operates from 06:00 to midnight. Frequency is every 3 to 8 minutes on weekdays and every 5 to 8 minutes on weekends and public holidays.

Key Stations and What’s Nearby

Sukhumvit Line

• Mo Chit. Northern terminus. Chatuchak Weekend Market is a short walk southeast (Saturday and Sunday only). Also connects to MRT Chatuchak Park for the Blue Line.
• Phaya Thai. Connection point for the Airport Rail Link to Suvarnabhumi Airport, around THB 45 and 30 minutes. Exit the BTS paid zone and buy a separate ARL ticket at the platform below.
• Siam. Free interchange between Sukhumvit and Silom lines across two platform levels. Closest BTS stop for Siam Paragon and MBK Center. Check the terminal name on the platform sign before boarding; first-timers frequently board in the wrong direction here.
• Chidlom. Erawan Shrine is directly outside Exit 1. CentralWorld and Gaysorn Village are a short walk from the same exit.
• Phrom Phong. EmQuartier and EmSphere connect directly to the station. Benchakitti Forest Park is about 10 minutes on foot heading south.
• Thong Lo. Bangkok’s main dining and bar strip for the expat crowd. Most venues spread along Sukhumvit Soi 55 heading east from the station.
• Ekkamai. Eastern Bus Terminal sits adjacent to the station, with buses to Pattaya and the eastern seaboard.
• On Nut. Budget accommodation hub with noticeably lower prices than the Asok and Phrom Phong stretch. Big C supermarket is in the station building.

Silom Line

• National Stadium. MBK Center and the Bangkok Art and Culture Centre are directly opposite the station.
• Ratchadamri. One block from the Erawan Shrine and the Red Sky rooftop bar at Centara Grand.
• Sala Daeng. Silom nightlife and Patpong Night Market are a few minutes on foot. Connects to MRT Si Lom station via a covered walkway.
• Chong Nonsi. King Power Mahanakhon building, with its glass-floor skywalk, is one block from the station.
• Saphan Taksin. River access point for the BTS network. Chao Phraya Express boats depart from the pier below for stops along the river, including Tha Chang pier (N9) for the Grand Palace. ICONSIAM also runs a free shuttle boat from this pier roughly every 30 minutes, operated by the mall itself — if you are already at Saphan Taksin, this is faster and free compared to doubling back to take the Gold Line.
• Krung Thon Buri. Transfer station for the Gold Line. Exit the Silom Line paid zone and board the Gold Line separately.

Gold Line

• Charoen Nakhon. ICONSIAM, use Exit 3. Also reachable by the free shuttle boat from Saphan Taksin pier.
• Khlong San. Terminal station. Mostly residential, with a few riverside restaurants.

Transfers to the MRT

Three BTS stations connect to the MRT Blue Line. Each transfer requires exiting the BTS paid zone and paying a new MRT fare. The Rabbit Card does not work on the MRT; use a single-journey token or tap a contactless Visa or Mastercard directly at MRT gates. For a full breakdown of MRT lines and stations, see the Bangkok MRT guide.

• Asok (BTS) / Sukhumvit (MRT). Connected by a covered walkway. The two stations carry different names because they were built by separate operators at different times.
• Mo Chit (BTS) / Chatuchak Park (MRT). Short above-ground walk between exits.
• Sala Daeng (BTS) / Si Lom (MRT). Street-level connection, under two minutes on foot.

Where the BTS Does Not Reach

The Grand Palace, Chinatown, and Khao San Road all sit outside the BTS network and catch first-timers off guard.

• Grand Palace and Wat Pho. Take the BTS to Saphan Taksin, then a Chao Phraya Express boat north to Tha Chang pier (N9). Alternatively, Grab from anywhere in the city center takes around 20 minutes outside peak hours.
• Chinatown (Yaowarat). MRT Blue Line to Hua Lamphong or Wat Mangkon station.
• Khao San Road. No BTS or MRT within practical walking distance. Grab is the standard option from the BTS network.
• Dusit and the Royal Palaces district. MRT Blue Line or Grab. No BTS coverage in this area.

Tips for First-Time Riders

• Direction signs. Platform signage uses terminal station names, not compass directions. On the Sukhumvit Line, trains run toward Mo Chit (north) or Kheha (southeast). On the Silom Line, toward National Stadium or Bang Wa. Know which terminal is in your direction before descending to the platform.
• Siam interchange. Switching between Sukhumvit and Silom lines at Siam costs nothing. Walk between platform levels inside the paid zone without tapping out.
• Peak hours. 07:00 to 09:00 and 17:00 to 19:00 on weekdays. Trains are noticeably less crowded after 10:00 and before 16:30.
• Cold carriages. Air conditioning runs strong on all BTS trains. A light layer helps on longer rides.
• Durian. Banned on all trains and platforms. If you have been to Chatuchak or any market, make arrangements before entering the station.
• Navigation. Google Maps handles BTS routing accurately and shows arrival estimates. It will tell you which line, which direction, and which exit to take.
