A lot of people treat Phetchaburi and Samut Songkhram as two separate trips, when in reality the two provinces practically run in a straight line. Driving from Bangkok along Rama II Road (Highway 35) takes you through Samut Sakhon, into Samut Songkhram, then onto Highway 4 for the last ten or so kilometres up to Phetchaburi. From downtown Phetchaburi back down to Amphawa is roughly 60–70 km — an easy hour's drive. That makes it a natural cross-province trip of 2 days and 1 night, picking off the highlights of both towns without ever doubling back.
We've set this trip up with day one in Phetchaburi, since it sits further north — tackle Khao Wang and the old temples in the morning while it's still cool, then drift south to spend the night in Amphawa. Day two covers Samut Songkhram: the railway market, the floating market and a firefly boat ride before heading home. This rhythm means you never drive against your own route, and you get a full night sleeping right by the canal.
Pick the right day for the markets (read before you plan)
Markets are the heart of this trip, and each one runs on a different schedule. Get the day wrong and you'll miss the best of it — this matters more than anything else. Plan around the days the markets are open first, then slot everything else in around them.
- Amphawa floating market — only buzzes Friday to Sunday, from early afternoon into the evening (roughly 11:00–20:30). On weekdays it's quiet with few stalls open, so aim to have your overnight fall on a Friday or Saturday night.
- Maeklong railway market (Talad Rom Hoop) — open every day, but the highlight is the moment the train rolls through. You'll need to check the timetable carefully (it's in the next block).
- Tha Kha floating market — a traditional morning market that only opens on the 2nd, 7th and 12th days of each lunar fortnight (roughly every 5 days). Stop by if the date lines up; if not, skip it — it's not a must.
- Firefly boat ride — runs for most of the year, but the fireflies are at their best from the rainy season into early winter, and on nights without a full moon.
Short version
To catch both the Amphawa floating market and the fireflies, base your overnight on a Friday or Saturday — and everything else falls into place on its own.
Book the activities in your Phetchaburi 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.
Day 1 — Phetchaburi: Khao Wang, old temples, mor kaeng custard
Phetchaburi → drift down to Amphawa
About where to stay
The popular canalside places in Amphawa book out fast on Friday and Saturday nights. If you're planning a weekend trip, reserve at least 1–2 weeks ahead. Rooms facing the canal cost a fair bit more than the inner ones.
Day 2 — Railway market, floating market, Wat Bang Kung, fireflies
Cover all of Samut Songkhram before heading back
Can you stretch it to 3 days?
If you have an extra day and want to go deeper, it's easy to expand this into 3 days and 2 nights. Add one nature day and the pace eases up a lot — you won't have to cram markets and temples into a single day.
Add a Kaeng Krachan day
Before dropping down to Amphawa, stop at Kaeng Krachan National Park in Phetchaburi to catch the morning sea of fog at Phanoen Thung — great for nature lovers and photographers.
For beach loversAdd a Cha-am beach day
This trip runs very close to Cha-am, so it works nicely to slot in a half-day at Cha-am beach — eat seafood and stroll the sand before heading into Phetchaburi town.
Add the Tha Kha morning market
If the date falls on the 2nd, 7th or 12th of the lunar fortnight, get up early for Tha Kha floating market — a traditional market where vendors still paddle their boats to sell, far less crowded and genuinely old-school.
Rough costs (per person, 2 days 1 night)
- Canalside stay in Amphawa — around 800–1,800 THB/night (split between 2 people per room, that's 400–900 THB each). Canal-view rooms cost more.
- 4–5 meals + market snacks — around 500–800 THB.
- Khao Wang (tram + entry) — from a few tens of baht up to the low hundreds.
- Firefly boat ride — 60–80 THB/person (whole-boat charter ~600 THB).
- Petrol + tolls, Bangkok round trip — around 600–900 THB/car, split by the number of people.
- Rough total — about 1,500–2,500 THB/person, depending on your accommodation and how many share the car.
Save even more
With 4 people sharing one car, petrol and accommodation come down a lot — and there's no need for a tour since the route is easy to drive yourself, with clear signs the whole way.
Tips to keep this trip smooth
- Driving yourself is by far the best option — the sights are spread out and public transport between Phetchaburi and Amphawa is awkward.
- Book your canalside stay ahead if you're going on a weekend; canal-view rooms sell out fast.
- Bring an umbrella or hat for Khao Wang — the sun is strong and there's little shade at the top.
- At the railway market, leave buffer time for the train rounds rather than cutting it fine, and stand back along the line where the vendors tell you to.
- Bring mosquito repellent for the firefly ride — the canalside gets buggy after dark.
- Buy all your souvenirs in one go on the way back — Phetchaburi mor kaeng custard plus coconut sugar / Maeklong mackerel.
