If you assume a trip near Bangkok has to be expensive, Nonthaburi will change your mind. Almost everything here is built around public transport. The MRT Purple Line runs from Tao Poon to Khlong Bang Phai, passing the Nonthaburi Civic Center, the Ministry of Public Health, and out toward Bang Yai — and from there you can cross the Chao Phraya River to Koh Kret for spare change. We walked it and checked the real prices: fares, ferries, and food, so you can plan with hard numbers instead of guessing.
The real per-person cost of one day in Nonthaburi
Let's start with the numbers, because this is exactly why people pick Nonthaburi for a cheap day off. Here's roughly what one person spends in a day, coming in from central Bangkok by metro.
- MRT Purple Line — flat 20 THB per ride, so 40 THB round trip (you have to register for the fare cap in the Thang Rat app first, otherwise it's the distance-based 14–42 THB)
- Ferry to Koh Kret — 6–10 THB round trip, depending on the pier and the day
- Lunch + riverside snacks — 100–200 THB if you stick to local stalls
- Coffee / Thai sweets / small souvenirs — 50–120 THB
- Temple and site entry — mostly free; donate as you wish
- Full-day total — about 250–450 THB per person, not even half a thousand
Register first for the cheapest fare
The flat 20 THB cap on the Purple Line is a benefit you have to register for: link your national ID in the Thang Rat app and connect a Rabbit card, an EMV card, or MRT Plus ahead of time. Tap a plain card and you'll pay the standard 14–42 THB. Sort it out at home before you head out.
Book the activities in your Nonthaburi trip ahead
Booking online ahead on Klook or GetYourGuide is usually cheaper than the gate and skips the queue. Pick only the experiences you actually want — prices and availability are shown live on each site.
How to chain the metro and ferry for the best value
The whole budget plan hinges on smooth transfers. The Purple Line connects to other lines at several points, so you can reach Nonthaburi from almost any corner of Bangkok without touching a car.
- Coming from the city center — take the Blue Line (MRT) to Tao Poon and walk across the platform straight onto the Purple Line; you never leave the system
- Coming from the east — the Pink Line meets the Purple Line at Nonthaburi Civic Center station (Sun Khae Rai); get off and transfer right there
- Getting to Koh Kret — take the cross-river ferry from Wat Sanam Nuea pier to Wat Pramai Yikawat pier, 3 THB during the day (5 THB early morning and evening); the Wat Klang Kret–Pa Fai pier route costs the same
- Cruise the river — from Tha Nam Non you can board a Chao Phraya Express boat for a low double-digit fare if you want the full riverside view
Weekdays are cheaper and quieter
Some piers charge 5 THB on weekends but 3 THB on weekdays. The difference is small, but the real bonus is that Koh Kret is far less crowded on a weekday — much easier to wander, take photos, and graze on snacks.
Day-by-day blocks — pick by how much time you have
We've laid out two options. Day one is a full day on Koh Kret and the riverside; day two is a temple–market–café crawl along the metro line. If you only have one day, do day one. If you're staying over or coming back for a second round, run them back to back.

Cheap eats you shouldn't miss
The value of Nonthaburi lives in its food, because it's still priced for the community, not for tourists. Here's what to track down, ranked by how worth-trying and how wallet-friendly it is.
Tod man no kala (bamboo-shoot fish cakes)
Koh Kret's signature dish — fried fish cakes made with no kala, a local bamboo shoot. Firm, fragrant, and eaten with cucumber relish. If you come to the island, you order this.
Mon-style khao chae
Rice in chilled, flower-scented water, eaten with an array of sides — fried shrimp-paste balls, sweet shredded pork, stuffed sweet peppers. An old-fashioned way to beat the heat.
Auspicious-name Thai sweets
Thong yip, thong yod, met khanun, ja mongkut — made fresh in the Koh Kret community and cheap, pretty gifts to take home.
Boat noodles & made-to-order at Tha Nam Non
The Tha Nam Non market has rice-and-curry shops, made-to-order stalls, and noodle vendors lined up in a row at true community prices — a full meal for a few tens of baht.
Khanom tuay fu (flower steamed cups)
Colorful steamed rice cups shaped like flowers, handmade by the community and hard to find in Bangkok. Very cheap and easy to snack on while you walk.
Nonthaburi durian (seasonal)
If you come in durian season, Nonthaburi is a famous source. It costs more than usual because the real thing is rare — but tasting it once is worth the experience.
Extra ways to save
- Bring a water bottle — walking Koh Kret under the midday sun, buying bottle after bottle adds up fast; carrying your own helps a lot
- Eat your main meal at Tha Nam Non, snack on Koh Kret — spend smart: fill up at the community market and save room for the island's standout bites
- Skip the stalls right at the main entrance — the shops deeper inside the community are usually cheaper and genuinely better
- Check the last ferry time — the cross-river ferry stops running in the evening; don't get so caught up that you miss it
- Buy souvenirs on the island, not at the entrance — Thai sweets and pottery inside the community are priced better than at the tourist spots
