The logic behind this plan is to treat the river as your main road. Nonthaburi Pier happens to be the northern start/end point of the Chao Phraya Express Boat, so it's an easy place to hop on. Day one you head south into Bangkok's old city, and you can either spend the night around Rattanakosin or come back to sleep on the Nonthaburi side. Day two you loop north to Koh Kret and close the trip out with food by the water.
The boats you'll use on this trip
There are several boat lines on the Chao Phraya, each at a different price, and picking the right type keeps things cheap and simple. The two you'll use on this trip are the express boat that locals actually commute on, and the tourist boat with a hop-on-hop-off all-day pass.
- Chao Phraya Express Boat (orange/yellow flag) — the commuter line for people heading between Bangkok and Nonthaburi. The Nonthaburi–Sathorn stretch runs about ฿24 end to end, and Pak Kret–Nonthaburi is around ฿17. Cheap and fast, great for getting around like a local, but there's no guide or commentary.
- Chao Phraya Tourist Boat (blue flag) — the tourist line. The All Day Pass lets you hop on and off all day for about ฿150 (a single ride is ฿30). It runs between Sathorn Pier, ICONSIAM, and up to Phra Athit, with English commentary on board — handy on day one when you want to stop at several piers.
- Cross-river ferries — used to cross over to Koh Kret (Wat Sanam Nuea–Wat Poramai Yikawat); fare is about ฿2–4, paid when you step off. The Tha Tien–Wat Arun ferry runs about ฿5 and operates roughly 05:00–19:00.
Know before you board
Since 2024 the Chao Phraya Express Boat no longer stops at the Wat Arun pier. If you want to visit Wat Arun, get off at Tha Tien first, then take the cross-river ferry to the other bank. Fares and schedules can change, so it's safer to check chaophrayaexpressboat.com before you set out.

Food you shouldn't miss along the way
Boat Noodles, Nonthaburi Pier
Nonthaburi is boat-noodle country — rich, dark broth in small bowls you can put away several of. A great way to start day one's breakfast at the pier market.
Thot Man No Kala, Koh Kret
A specialty unique to Koh Kret — fish cakes made with crunchy galangal shoots, hard to find anywhere else. Easy to grab and eat while you cycle.
Khanom Jeen Nam Ya, Koh Kret
Several shops on the island make Mon-style nam ya — well-balanced and mellow, eaten with fresh vegetables. A solid day-two lunch.
Mon Sweets (thong yod, bua loi, khanom kong)
The Mon community on Koh Kret has been making these sweets for generations, many of them fresh at the shopfront. Just sweet enough, and good to take home.
Tha Maharaj Riverside, Bangkok
Sit with a view of Wat Arun across the river. There's both Thai food and cafés — a good afternoon break on day one after temple-hopping.
Pa Thong Ko & Old-Style Coffee, Nonthaburi Pier Market
A simple breakfast before you board — hot old-style coffee with freshly fried pa thong ko, in a classic morning-market setting.
Where to stay during this trip
Rattanakosin side (Bangkok)
Stay near Wat Arun–Khao San so you can wander the old city at night and visit the temples easily first thing in the morning.
Nonthaburi Pier side
Come back to the Nonthaburi side so you can set off for Koh Kret quickly on day two. Rooms here tend to be cheaper.

- Avoid rush hour — the morning and evening express boats get packed because commuters genuinely rely on them. If you're traveling at a relaxed pace, starting after 9 a.m. makes for a more comfortable ride.
- Bring small cash — the cross-river ferries and most shops on the island take cash only, so keep coins and ฿20 notes on hand.
- Koh Kret is full on weekends, quiet on weekdays — on Saturday–Sunday every shop is open but it's crowded; if you prefer cycling in peace, go on a weekday, though some shops will be closed.
- Sun and rain protection — a lot of this trip is outdoors and by the water. A hat and a folding umbrella help with both the sun and the rainy-season showers.
