What confuses first-time visitors to Bangkok is that a pier has several boats in different flag colours, each stops for only a moment, then leaves — so which one do you board? In reality the boats on the Chao Phraya fall into four main groups: the express boats (the commuter boats), the cross-river ferries (short hops to the other bank), the blue-flag tourist boats (a 9-pier hop-on route), and the evening dinner cruises. Understand these four groups and getting around riverside Bangkok is easy.
Chao Phraya Express Boat — the commuter boat
The Chao Phraya Express Boat is the local commuter line that Bangkokians ride to work every day. It runs the long stretch from Nonthaburi down to Ratchawong–Sathorn, and it's fast and very cheap. The key thing to know is that the boats are split by flag colour on the bow, and each colour stops at a different set of piers — check the flag before you board or you may sail past your stop.
- Orange flag — the main, most popular line. It stops at nearly every important pier, runs all day every day, costs around 18 THB for the whole line, and is the best fit for travellers.
- Yellow flag — the limited-stop express. It skips most piers and runs faster, around 23 THB, focused on weekday rush hours, morning and evening.
- Green–yellow flag — the long-distance line all the way to Pak Kret, with few stops. The fare is by distance, around 16–35 THB, and it runs only during weekday rush hours.
- No flag (local boat) — stops at every pier, the slowest but cheapest, running only at certain times. Good if you're not in a hurry and want a smaller pier.
Keep it simple
If you're a traveller and don't want to overthink it, just remember the orange flag. It stops at Tha Tien (Wat Pho / Wat Arun), Tha Chang (Grand Palace), Phra Athit (Khao San) and Sathorn (BTS Saphan Taksin) — every spot a traveller wants — and it only costs a handful of baht.
Boarding is easy: walk onto the pier, buy a ticket from the conductor holding a coin tube (or at a ticket window at some piers), tell them where you're getting off, then wait for the boat. When it pulls in, board quickly — it stops for only a few seconds. To get off, move toward the back of the boat before your pier; the conductor calls out every stop.

Cross-river ferry — across the river for a few baht
The cross-river ferry is a small boat that cuts straight across the river from one bank to the other in just 2–3 minutes, and the fare is dirt cheap at around 4–5 THB a trip. It's the unsung hero of temple-hopping, because the major temples sit on opposite banks.
- Tha Tien ↔ Wat Arun — the most famous crossing. Get off at Tha Tien, walk to Wat Pho, then ferry across to Wat Arun on the other side for around 5 THB.
- Tha Chang ↔ Wang Lang (Siriraj) — from the Grand Palace side across to Wang Lang Market, packed with food.
- Si Phraya ↔ Khlong San (IconSiam) — cross from the Charoen Krung side straight to the IconSiam mall.
Don't mix them up
The cross-river ferry and the express boat use a different side, or a different bay within the same pier. The ferry cuts straight across, while the express boat runs parallel along the river. Look for the ‘Cross River' sign at the pier and you'll find it.
Blue-flag tourist boat — hop-on hop-off
If you don't want to gamble on flag colours and would rather sit comfortably, there's the blue-flag Chao Phraya Tourist Boat. It runs only the key central stretch, from Sathorn (BTS Saphan Taksin) up to Phra Athit (Khao San), stopping at around 9 main sightseeing piers. There's an English-speaking guide on board and the seats are comfier than the express boat.
- One-Day Pass — around 150 THB for unlimited hop-on, hop-off all day. Worth it if you plan to see several temples.
- Single trip — around 40 THB a ride, fine if you only need one journey.
- Boats run roughly 08:30–19:40 every 30 minutes, and in the evening the route extends to Asiatique.
The difference from the express boat is that the blue flag costs several times more, but you trade up for comfort and commentary. If it's your first Bangkok trip and you're temple-hopping all day, the one-day pass pays off. But if you just want a single ride from Sathorn to Wat Pho, the orange-flag express boat at a few baht is far cheaper.
Key piers — which stop for what
Sathorn (Central Pier)
The biggest pier, linked to BTS Saphan Taksin exit 2. The starting point for almost every type of boat and for several dinner cruises.
Tha Tien (N8)
Step off and walk straight to Wat Pho, then take the cross-river ferry to Wat Arun on the far bank. Cute cafés and pretty river views nearby.
Tha Chang (N9)
The closest pier to the Grand Palace and Wat Phra Kaew, a short walk away. A good start for the old Rattanakosin quarter.
Phra Athit (N13)
The northern end of the line, a short walk to Khao San Road and the Phra Nakhon district. Great for backpackers.
Wang Lang (N10)
On the Thonburi side, next to Siriraj Hospital, with Wang Lang Market full of cheap, busy food stalls. A good lunch stop.
Ratchawong (N5)
An easy walk into Yaowarat (Chinatown): browse the markets by day, eat street food after dark.
Save time
From 08:00–09:00 in the morning and 17:00–18:30 in the evening the express boats are packed with commuters. If you're sightseeing at a relaxed pace, avoid those two windows — the boats will be quieter and you can take in the views and photos properly.
Dinner cruise — dining and city lights after dark
After dark the Chao Phraya shifts mood: Wat Arun lights up, and IconSiam and the Rama VIII Bridge glow. This is dinner-cruise time — big boats that drift slowly for around 2 hours with a buffet and live music. Most leave from IconSiam, River City, or Asiatique, with prices that vary by the boat's class and food.
Chao Phraya Princess
A popular two-deck boat that's been on the river for over 30 years. A Thai-international buffet with seafood like river prawns and mussels, plus live music. A good pick if you want a solid, standard cruise at an affordable price.
Wonderful Pearl
A large boat with a modern pearl-shaped design and a lively atmosphere, with a cabaret show and live music. A good fit for groups of friends or a special occasion where you want some fun.
Saffron Cruise
A premium cruise from Banyan Tree serving a chef-made Thai set menu, focused on quality food and a quiet, refined atmosphere. Best for couples or a special meal where you don't want a show.
Loy Nava
Bangkok's first dinner cruise, running since 1970, aboard a small antique teak rice barge serving a traditional Thai set menu. A classic, peaceful atmosphere with limited seats, so book ahead.
Straight talk
Dinner cruises are about the atmosphere and the views first. The food is mostly ‘good enough', not Michelin level, so if you're hoping the meal is the star you may be let down. But if you're here to see Wat Arun and the bridges by night in the breeze, it's well worth it. Book ahead, especially on weekend and festival nights.
Fares and quick tricks
- The cross-river ferry is cheapest at ~4–5 THB · orange-flag express ~18 THB · blue-flag tourist boat ~40 THB/trip or ~150 THB for the whole day.
- Keep coins and small notes ready for the fare — conductors aren't keen on breaking large bills.
- Express boats stop for only a few seconds, so move to the back of the boat before your pier.
- When the tide is high or the boat is full, the walkway can sway — watch your belongings and hold the rail firmly.
- In the rainy season (Jun–Oct) bring an umbrella, as the seats along the side catch spray and rain.
