Your Travel Guide to Thailand
All information & tips to prepare your trip in Thailand
For tourists, the most useful lines for getting around Bangkok and visiting the main sights are the original BTS lines and especially the MRT. First of all, the MRT Blue Line, which stops in Chinatown and near the Grand Palace, the Temple of the Emerald Buddha and Wat Pho (Sanam Chai station). The Airport Rail Link easily connects downtown Bangkok with Suvarnabhumi International Airport, while the new Red Line goes to Don Muang Airport. The Gold Line's only real interest is to reach the gigantic, upscale ICONSIAM shopping mall.
Bangkok's metros connect with the Chao Phraya Express boats at BTS Saphan Taksin station (Sathorn pier on the Chao Phraya Express), and with the boats on the khlongs (canals): at MRT Phetchaburi station for the Khlong Saen Saep boats and at Hua Lamphong for the Khlong Phadung Krung Kasem boats.
In general, the metro and Skytrain, possibly combined with the river boats, are the best way to get around Bangkok. They are affordable and air-conditioned, you don't get stuck in traffic jams, and you don't breathe exhaust fumes as you do in a tuk-tuk. Once you've started using them, I'm sure they will quickly become your favorite way to get around the city – especially since the network is growing faster than ever!
I recommend downloading the ViaBus smartphone app to plan your public transport journeys in Bangkok. Available on Android and iOS, it brings together all the public transport networks and shows you every possible route from your starting point.
