Quick Answer: Which Boat Should You Take?

Pick by what you want from the ride. Sightseers get the most from the tourist boat, which costs ฿150 for an unlimited day ticket or ฿30 for a single trip. Budget riders and commuters do better on the orange-flag boat at ฿15. Services without the orange flag run on weekdays at peak hours only, so check the day and time before you plan around them.

• First-timer: blue-flag tourist boat, Sathorn to N13, daily 09:30-16:00.
• Temple-hopper: tourist boat or orange flag to N8 Tha Tien, N9 Tha Chang and N13 Phra Arthit.
• Budget rider: orange flag at ฿15, daily 06:00-19:00.
• Weekday commuter-hours rider: green, yellow or no-flag boats, which skip many piers.

Chao Phraya Express Boat Types by Flag Color

Each flag marks a different stopping pattern, price and operating window. Orange is the everyday line, at ฿15 and roughly every 15 minutes from 06:00 to 19:00. Green, yellow and no-flag boats only run on weekdays in the morning and late-afternoon peaks. Tourist boat tickets are sold ahead of boarding, while other boats collect fares on board. All figures are provisional, so check the operator's timetable and fare page for current services.

Key Piers for Sightseeing

Piers north of Central Pier carry an N prefix, and piers to the south carry an S prefix. Most visitor sights sit between Sathorn and N13, a ride of about 30 minutes on the tourist boat. Pier names and numbers can change, so match them against the posted pier map when you board. Sathorn also sits beside Saphan Taksin station, which makes it an easy hand-off from the BTS Skytrain network.

How to Ride: Tickets, Boarding, Getting Off

Tourist boat tickets are sold at Central Pier and N13. They are also sold at Saphan Taksin and Siam BTS stations, though you should confirm that is still the case. Other services collect the fare on board, so keep small change ready. Exact fare helps the conductor. Move toward the front after boarding. Passengers who want the next stop stand near the rear. Boats only call at a pier when someone is waiting or getting off, so stand early. Not every service stops at every pier either. Check the route map at the pier before you board.

Cost and Time Trade-Offs

For a temple-area trip, the boat is usually the cheapest option per ride. An orange-flag fare of ฿15 beats nearly any road alternative. The tourist boat costs more, with ฿30 for one trip, but it is less crowded and has English commentary. A ฿150 day ticket only pays off if you ride several legs. Rail is faster when you only need to reach Sathorn, since Saphan Taksin BTS leads straight to the pier. See our Skytrain station guide for the exit details. When MRT plus a short walk works better for the old town, check the MRT routes near Rattanakosin. For door-to-door trips or evenings after the boats stop, compare Grab rides with tuk-tuk rides and agree on the price first.

• Boat: lowest fare, scenic, but fixed piers and set hours.
• BTS/MRT: air-conditioned and reliable, but needs a walk or ferry to the river temples.
• Grab or tuk-tuk: door-to-door and available after dark, but traffic can slow the old town.

Sample Routes

Use these sequences as outlines. Skip timings until you have checked the current timetable.

• Temples loop: board at N8 Tha Tien for Wat Pho, cross by ferry to Wat Arun, return and continue to N9 Tha Chang for the Grand Palace.
• Chinatown to Khao San: start at N5 Tha Rachavongse for Chinatown, then ride north to N13 Phra Arthit.
• Commuter-hours ride: on a weekday morning or late afternoon, take a green, yellow or no-flag boat and confirm its stops at the pier before boarding.

Cross-River Ferries and Hotel Shuttle Boats

Small cross-river ferries serve most piers. Fares run about ฿2 to ฿4, usually paid at the pier entrance before you board. Seating is limited, so expect to stand for the short crossing. At N8 Tha Tien, this is the ferry that reaches Wat Arun. Hotel shuttle boats are free and run between riverside hotels such as The Oriental, The Peninsula and Bangkok Marriott, mostly via Central Pier. Treat them as meant for hotel guests and diners unless the hotel says otherwise. If you are arriving by plane, our airport-to-city options explain how to reach a riverside hotel.

Mistakes to Avoid

Most problems come from timing and boarding. Weekday-only flag boats do not run on weekends, so do not rely on them outside the peak windows. Orange-flag boats stop at 19:00, so do not assume a late evening ride. Watch which side of the pier your boat uses, since services dock at different points. Stand near the rear before your stop, because boats can leave quickly. Midday heat and rush-hour crowding can make a long ride tiring, so carry water and plan for the 09:30-16:00 tourist boat window if you want a seat.

• Using a peak-hour-only flag boat at midday.
• Missing your pier by waiting too long to stand.
• Assuming every service stops at N8 or N9.
• Expecting ferries or boats to run late into the evening.
