The River
The Chao Phraya
The river that orders this part of the city, and the western edge of the district Bangkok Gem Hotel stands in.
In Bang Rak the Chao Phraya is not scenery you visit — it is a route people use. Boats run to timetables, piers have numbers, and for a good part of the day the water moves across the city faster than the road beside it.
Two different boats
The services on the river are not one system. The Chao Phraya Express Boat is the commuter operator: scheduled boats running under flag-coded lines — orange, yellow, green-yellow and red — several of which terminate at Sathorn. It is a local transport service, priced and timed as one.
The Chao Phraya Tourist Boat is a separate hop-on-hop-off operation with its own route, its own ticket and its own stopping pattern, departing every 30 minutes and calling at eleven piers. A ticket for one is not a ticket for the other, which is the single most common mistake visitors make at the pier.
Sathorn is the interchange
Both operators call at Sathorn Pier, and the tourist boat identifies it in its own material as the BTS Saphan Taksin interchange. That pairing — the Silom Line station at the river end of the district, and the pier beside it — is the connection the whole riverside works around.
Currently out of service: the operator lists Oriental Pier (N1) as closed for renovation. No route on this site is planned through it. Checked 16 August 2026 — the operator is the only authority on when it reopens.
What this page will not tell you
No timetable, no fare and no pier-by-pier list appears here. All three are set by the operators, all three change without notice, and a copy held on a hotel website is wrong the moment it is published. The operators’ own pages are linked below and are the only version worth trusting on the day you travel.
