Getting around
Lopburi

The train is the most commonly recommended way to reach Lopburi for anyone planning to explore the old town, because Lopburi railway station sits right in the heart of it. Phra Prang Sam Yot is directly across from the station, practically a street crossing away. San Phra Kan Shrine is just a short walk further, while King Narai's Palace and the Royal Ambassador's Residence (Ban Vichayen) are within a few hundred meters on foot. Once you step off the train, there's barely any need to transfer to another vehicle — you can cover the main ancient sites on foot in a comfortable half-day. Lopburi sits on the northern and northeastern rail lines, with several trains running from morning to evening, departing from both Krung Thep Aphiwat Central Station and, for some services, Hua Lamphong. The distance is around 150 kilometers, taking roughly two and a half to three hours depending on the train type.

What makes the train worthwhile is its very low price — ordinary 3rd class costs just tens of baht, while express trains or better seating classes still only run to around a hundred baht. It's also the most fitting way to see Lopburi's old town, since you skip the hassle of finding parking, which is limited and tight in the old town. One thing to keep in mind is that Thai trains can sometimes run behind schedule, so build in extra time if you have a tight connection. 3rd class carriages are fan-cooled without air conditioning, so it can get fairly hot during the day. Also, if you want to visit sites further out like the Pa Sak Jolasid Dam or the sunflower fields, the train alone won't get you there — you'll need to transfer to a songthaew, hire a car, or use a tour service.

Buses and vans are an option for travelers who want to reach Lopburi faster than the train and with more departures to choose from. Most services run from the Mo Chit 2 bus terminal on the northern side, with frequent vans as well as scheduled buses that pass through Lopburi on their way to towns further north. Van fares run just over a hundred baht per trip, while buses are a bit cheaper still. If the roads aren't congested, the journey takes about two to two and a half hours to reach town. The advantage over the train is that it's usually faster and offers more departure times throughout the day, which suits travelers leaving Bangkok a bit later or wanting flexibility on their return time.

What to keep in mind is that traffic entering and leaving Bangkok can add significant time, especially during rush hour and long holiday weekends. Van seating tends to be fairly cramped with limited luggage space, so travelers with a lot of bags may find it less convenient. Another key difference from the train is that bus/van drop-off points are usually at a bus station or roadside in town, not right in the old town next to the ancient sites like the train station is. This means you'll need to transfer by songthaew, motorcycle taxi, or Grab to reach your hotel and the old town. Before boarding, ask the ticket seller clearly where exactly the drop-off is and how close it is to where you're headed, so you can plan your onward transfer.

Self-drive car rental is the most flexible option for travelers who don't want to limit themselves to just the old town, but also want to reach sites scattered outside Lopburi town. Several of Lopburi's well-known attractions lie further out with no convenient public transport access, such as the Pa Sak Jolasid Dam in Phatthana Nikhom district, the sunflower fields that bloom in the cool season, and Khao Chin Lae. Rental cars are available both from Bangkok, for a self-drive journey of about 150 kilometers taking roughly two and a half hours, and within Lopburi town itself. A typical sedan costs around 1,000-1,800 baht per day depending on the model and season, not including fuel and toll fees. The advantage is that if you're traveling with several people splitting the cost, it becomes worthwhile, letting you cover both the old town and outlying sites in a single day without waiting on songthaews or hoping to catch a Grab.

Something specific to know about Lopburi is that the streets around the old town near the train station are fairly narrow, with limited parking, and finding a spot can be difficult on busy days. Sightseeing in just the old town by private car is therefore less convenient than arriving by train and walking. Another point not to miss: Lopburi is famous for its large monkey population in the old town, especially around Phra Prang Sam Yot and San Phra Kan Shrine. The monkeys are used to people and mischievous, often climbing onto parked cars, pulling off windshield wipers, grabbing items, or prying open windows left slightly open. Park away from areas with lots of monkeys, keep windows fully closed, and keep valuables and food bags out of sight, and never leave a door open. If you're only visiting the old town, arriving by train and walking is still more comfortable and cheaper than driving in to find parking.

Among Thailand's old towns, Lopburi is one of the easiest to explore entirely on foot, because the main ancient sites cluster around the train station within walking distance of each other. Phra Prang Sam Yot sits directly across from the station, San Phra Kan Shrine is just a few steps further, and King Narai's Palace and the Royal Ambassador's Residence are a few hundred meters away. Travelers arriving by train can walk to all the main sites in a comfortable half-day without needing any vehicle at all. For those who'd rather save their legs, bicycles can be rented in a few places in the old town for around 50-100 baht a day — though it's worth noting honestly that Lopburi has far fewer bicycle rental shops than Ayutthaya, and at times you may not find one available right away. If you plan to cycle, it's worth asking your hotel in advance.

Something everyone should be prepared for before walking Lopburi's old town is the monkey population. The area around Phra Prang Sam Yot and San Phra Kan Shrine is home to large numbers of long-tailed macaques that are very used to people and quite bold. They often jump onto visitors, pull at bags, snatch food or water bottles from hands, and like to grab small items such as glasses, hats, or phones held loosely. While walking around, avoid visibly carrying food or plastic bags, keep valuables in a securely closed bag, avoid direct eye contact, and don't provoke them. If a monkey approaches, stay calm and slowly walk away. The midday sun in the old town is fairly strong and the ancient sites are open ground with little shade, so it's best to walk or cycle in the morning or late afternoon, bringing water, a hat, and sunscreen for a more comfortable visit.

Grab and hired taxis are options for travelers without their own car who want to reach outlying sites occasionally without driving themselves. It has to be said plainly that Lopburi is a mid-sized provincial town, and the number of Grab cars in the system is far fewer than in Bangkok or major tourist cities. In town, at certain times you may call one and wait a long while, or find no cars available at all, especially around midday when fewer drivers are working, or in the evening. Relying on Grab alone is therefore risky, and you should build in extra time and have a backup plan if you need one. Another option locals use is contacting a local taxi or van driver to hire for a trip to an outlying site, such as the Pa Sak Dam or the sunflower fields, charged per trip or per day.

Hiring a car to an outlying site typically costs from the high hundreds of baht per trip up to a thousand-plus per day, depending on distance, number of stops, and negotiation. The advantage is not having to drive yourself, not needing to find parking, and more flexibility than a songthaew running a fixed route. This suits small groups or families wanting to visit just one or two outlying sites and return. Before agreeing, ask clearly whether the price includes waiting time between stops, how many stops are included, and how long the driver will wait. If your hotel or a local can recommend a driver at a fair price, that's more reassuring than hailing a stranger. For sightseeing within just the old town, Grab or taxis are barely necessary since everything is within walking distance.

The songthaew is Lopburi's cheapest form of local transport — a converted pickup truck with a roof and long bench seats on either side, running fixed routes within town and connecting to surrounding districts. Fares are very cheap, just tens of baht per ride depending on distance, and it's genuinely how locals get around. It suits budget travelers who want to soak up the everyday atmosphere of the town and aren't in a rush. Board at a stop or flag one down along the road, and pay when you get off. If you're not sure which direction a songthaew is headed, it's best to ask the driver or another passenger before boarding.

What's important to understand is that songthaews don't run on a fixed timetable — frequency depends on the route and time of day. Some in-town routes run often, but routes to farther districts may have long waits and limited runs. Many stop running in the evening. Anyone planning to use a songthaew to reach an outlying site should ask locals or their hotel which route goes where they want and what time the last return run is, to avoid getting stranded. Seating is open-sided long benches, which gives good airflow but also exposes you to dust and heat depending on road conditions. For sightseeing in just the old town district around the train station, a songthaew is barely necessary since the ancient sites are all within walking distance — but for reaching a market, a hotel area further out, or an outlying district on a budget, the songthaew is the most cost-effective choice.
