Bangkok Chao Phraya River Boats
Thai Smile Boat is one more addition to the system of Bangkok public transportation, where water transport plays quite an important role.
Even if these boats are operating on the same part of the Chao Phraya River as the Chao Phraya Express Boat, Thai Smile Boat routes are a bit different and served by larger electric boats, providing more comfort on board. As all Bangkok riverboats use the same piers, you can easily choose a preferred type of boat for your trip.
Bangkok cross-river ferries connect both banks of the Chao Phraya River in the Thai capital. They can be used in combination with Thai Smile Boat or other boats operating along the river in case you find yourself at the pier that is not on the route of the river boats.
As a tourist, you can also charter a boat and explore the city’s canals or join one of Bangkok river cruises and admire the city views from the river while enjoying dinner on the boat.
You can also use the Chao Phraya Tourist Boat, which lets you explore the attractions along the Chao Phraya River by hopping on and off the boats with a day pass.
Here you will find the most important information about the electric Bangkok riverboat service, Thai Smile Boat.
Thai Smile Boat Routes
The Thai Smile Boat service operates at around 20 piers along the Chao Phraya River, so it is not as widely available as the Chao Phraya Express Boat. However, the most important tourist attractions can be visited by using the electric Bangkok riverboat. The starting point of Thai Smile Boat routes is the Central Pier, also known as Sathorn Pier. Sathorn Pier is conveniently connected with BTS Saphan Taksin station and can be easily reached from anywhere in Bangkok by using city trains. In 2025, the City Line was extended, and now it's starting at Siam Charoen Nakhon Pier, but boats still make a stop at Sathorn Pier.
Currently, there are 2 routes served by Thai Smile Boat:
- City Line (green one)

Thai Smile Boat Tickets & Fare

Boat tickets can be purchased at the desk of Thai Smile Boat found at the passenger piers along the route. If there is none, you should be able to buy a ticket on board.
If you are planning to use the boat several times a day or are going to also use the electric Bangkok bus of the same company (Thai Smile Bus), consider getting an HOP Card that can be used to tap and pay for fares for public electric buses and boats.
With this card, you save time needed to purchase separate single-trip tickets. HOP Card can also help you save money if you will be using the service several times a day. There is a promotion for HOP Card holders called Daily Max Fare, which lets you travel by Thai Smile Boat all day for only 40 THB or choose to travel by bus and boat all day for only 50 THB.

Tips

While Thai Smile Boat can be used for exploring the attractions along the Chao Phraya River, it misses some of the popular spots, such as Khao San Road, Asiatique, and a few others. To visit all the main attractions conveniently, get a day pass for the Chao Phraya Hop-on Hop-off Boat.
