What makes Lopburi fun is that you get two completely different trips in one province. The first is the old town around the railway station, where the ruins from King Narai's reign are nearly all within walking distance of each other — step off the train and you can start sightseeing on foot, no car required. The second is the nature side outside the city, around Phatthana Nikhom district, with the big dam and the sunflower fields up on the hill — and for that you do need wheels. So this plan keeps day one inside the city and saves the out-of-town stuff for day two, which means no driving back and forth.
Lopburi is at its best in the cool season, roughly November to January: the sunflowers are in bloom, the weather is comfortable for walking the old town, and it's the only window when the floating train runs. Come at other times of year and you can still do the old town and the dam — you just won't get the flower fields or the special train.
Before you go — how to get there and where to stay
If you're set on doing the old town car-free on day one, taking the train from Bangkok (Hua Lamphong) or Krung Thep Aphiwat Central Station to Lopburi station is the easiest move. It runs about 2–3 hours depending on the service, and the moment you step off you can walk straight into the ruins. But if you want to reach the dam and the sunflower fields on day two, it's best to drive your own car or rent one, since the out-of-town spots are spread apart and public transport is thin.
- Stay in the old town — within walking distance of Phra Prang Sam Yot, Narai's palace and the food. Ideal if you arrive by train; get up early and walk before the sun gets harsh.
- Stay in the new town (near Sa Kaeo roundabout / Central) — newer hotels with easy parking. Good if you drive in and plan to head out of the city on day two.
- Stay near Pa Sak Jolasid Dam — there are riverside resorts around Phatthana Nikhom, good if you want to wake up to the dam view first thing. Just note it's far from the old town.
Book ahead in the cool season
November to January is Lopburi's high season. Old-town and dam-side rooms fill up fast on long weekends and on the Saturdays and Sundays the floating train runs. If you're planning to come during this window, booking your room and train tickets several weeks ahead will save you a lot of stress.
Book the activities in your Lopburi 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 — Narai's Old Town + the monkeys
Day one is all within walking distance. The main ruins sit around Lopburi railway station — start a little early for nicer light and before the sun gets strong. Entry fees at each spot are only a few tens of baht, and the whole day still comes in under 100 THB.

What you need to know about the monkeys
The monkeys in Lopburi's old town are smart and very fast. Don't walk around holding plastic bags or sweet drinks, and keep your phone and bag held tight. Feeding them yourself isn't a good idea — they'll swarm and can turn aggressive. If a monkey climbs onto you, stay still and slowly walk away; don't flick it off or hit back.
Day 2 — Pa Sak Dam + the sunflower fields
Day two heads out of the city toward Phatthana Nikhom district. It's about an hour's drive from town to Pa Sak Jolasid Dam, and the dam, the sunflower fields and the viewpoint are all in the same area — easy to loop in one day before heading back. You'll need a car for this part.

When do the sunflowers bloom?
Lopburi's sunflowers don't all bloom across the province at once — each plot is planted at a different time. Before you go, check the Facebook page of the specific plot or TAT Lopburi to see which fields are in bloom right then, so you don't show up to a plot that's already been harvested. The surest window is mid-November to early January.
Want to take the floating train instead — how to adjust the plan
If you'd rather have the experience of riding the floating train than drive, you can rework the plan. The special service leaves Bangkok (Hua Lamphong) around 06:00, reaches the mid-dam viewpoint around 09:20, stops for photos, then pulls in at the Pa Sak Jolasid Dam halt around 10:35, leaving you time to explore the dam through midday. The return leaves the dam around 15:30 and gets back to Bangkok around 18:50 — a day trip out in the morning and back in the evening.
- Runs Fri–Sun only, Nov–Feb — it's a seasonal special service, not daily. Check that year's schedule with the State Railway first.
- Round-trip 3rd class (fan) around 350 THB — air-conditioned coaches (OTOP Train / JR-West) run around 620 THB.
- Book via D-Ticket or at the station — tickets go on sale in advance and sell out very fast, especially the air-con cars, so book the moment they open.
- If you take the floating train, you only get the dam zone — there's no onward transport from the dam to the sunflower fields. If you want the fields too, drive yourself instead.
Which should you pick?
If you're traveling with a couple of people and want both the sunflowers and the dam in one day, driving yourself is more flexible and better value. But if you want the experience of riding the train and taking in the views without driving, the floating train is more fun — you just trade it off against only being able to see the dam zone.
Rough budget per person
Lopburi can be done cheaply — ruin entry fees are low and food isn't expensive. The biggest chunks are accommodation and transport. Here's a rough estimate for 2 days 1 night if you drive yourself.
- Day-one ruin entry fees — Phra Prang Sam Yot, Narai's palace, Ban Vichayen and Wat Phra Si Rattana Mahathat together, around 120–150 THB.
- 1 night's accommodation — old-town guesthouses start around 500–800 THB; mid-range hotels around 900–1,500 THB per room.
- Food over 2 days — eating at local spots, around 400–600 THB per person; add a bit more if you sit down at a riverside place by the dam.
- Sunflower-field entry + parking — around 50–100 THB.
- Rough total — around 1,500–2,500 THB per person (not counting fuel / getting to Lopburi), for an easy, no-frills trip.
Combining Lopburi with other provinces
Lopburi connects to several provinces. If you have more than two days or want a longer route, it links up easily.
Lopburi + Ayutthaya
Two historic cities right next to each other — you can do a continuous ruins trip, driving or taking the train on the same line.
On the wayLopburi + Saraburi
Saraburi is right on the way between Bangkok and Lopburi — add a stop at Wat Phra Phutthabat or the Saraburi sunflower fields.
Long tripLopburi + Phetchabun
Drive further north to Khao Kho and Phu Thap Boek, building on Lopburi's nature side — good for a longer multi-day trip.
