Doing It Yourself by Train

Yes, easily, and from about 15 baht. Here is the honest version, including the part where doing it yourself is not always cheaper.

Both Bangkok stations serve it

This is the detail most guides get wrong. Hua Lamphong was not fully closed when long-distance services moved to the new terminal — it still runs ordinary trains to Ayutthaya.

From Hua Lamphong: about eleven ordinary services a day, third class only, 15–20 baht. These cannot be booked ahead; you buy on the day at the station. Journey around 1h35 to 2h.

From Krung Thep Aphiwat Central Terminal (Bang Sue, on the MRT Blue Line): sixteen to nineteen services, the faster Special Express, Express and Rapid trains. 45 minutes to about 1h25. Third class from around 20 baht, second class with a fan around 61, second class air-conditioned 245–310.

So the choice is a two-hour crawl for the price of a bottle of water, or under an hour in air conditioning for roughly the price of a meal.

On arrival: a 5-baht ferry crosses the Pa Sak River from beside the station to the island where the ruins are.

The fares are ranges, deliberately

We are quoting these as ranges because they come from consistent secondary sources rather than a tariff we could pull from the railway itself. They agree with each other closely enough to plan on, and not closely enough for us to print a single figure and call it exact.

The same applies to the minivans from Mo Chit, every 20–30 minutes, one to one and a half hours: quoted anywhere between 60 and 150 baht depending on source and operator, with the most recently updated source at the top of that range. The government bus is around 56 baht with only three departures a day.

One practical tip that is worth more than the fare: on the bus or minivan, do not get off at the bus station outside the old city. Stay on to the last stop on Naresuan Road, which is on the island.

The part that actually costs money

Here is the finding that reframes the whole comparison.

The park itself is free. There is no gate around the historical park, and walking among the ruins costs nothing. You pay per temple.

Since 2 June 2025, for foreign visitors that is 80 baht per temple, or a 300-baht combined ticket covering seven monuments — Wat Mahathat, Wat Ratchaburana, Wat Phra Ram, Wat Phra Si Sanphet, Wat Chaiwatthanaram, Wat Maheyong and Wat Kudi Dao. Thai nationals pay 10 and 40 respectively.

The fee rose from 50 baht, and a great many guides have not caught up — some still publish “50 baht, confirmed for 2026”. They are quoting a rate that changed over a year ago.

Dual pricing is openly published Thai policy across historical parks, not an improvised charge. The ratio here is 8:1.

What a day actually costs

Budget — train, ferry, bicycle:

Comfortable — air-conditioned train, tuk-tuk on hire:

So the honest comparison: a budget self-guided day undercuts every tour on the shelf. A comfortable one costs more than the two cheapest tours and less than the other eight — and you are still doing your own navigating and your own explaining.

And notice what dominates both columns. It is the 300-baht ticket, not the travel. The train can be 30 baht round trip. Anyone telling you the transport is the expensive part has not added it up.

Getting around once you are there

The ruins are spread across the island, not clustered. Bicycles run 50–100 baht a day and are the pleasant option in the cool season. A tuk-tuk is roughly 200–250 baht an hour or about 1,000 for the day — agree the price and the list of stops before you set off, not after.

In April, when highs average 35.4°C on open brick with no shade, the bicycle stops being the pleasant option.

When the tour is the better buy

We sell tours, so treat this as the biased party conceding ground.

Take the tour if you want the history explained, if you are travelling in the hot season and would rather not cycle, if you want hotel pickup, or if the 300-baht ticket plus a hired tuk-tuk was going to cost you more than the tour anyway — which, as the second table shows, it does against the cheapest options.

So if the sums came out that way, here is that tour’s live calendar rather than a link somewhere else:

Go independently if you want to choose your own temples, linger, and travel on 30 baht of train tickets. It is a genuinely good day and the trains are part of the pleasure.

The guided days are here, including the honest note on which of the two big sellers we would actually book.
