Bangkok to Khao Yai (Pak Chong) — Train, Minivan or Northeastern Bus, and Why "No Transport Inside the Park" Is the Real Problem
Khao Yai is easy to reach and hard to explore. How to get to Pak Chong by train, van or bus, and how to get around Thailand's most visited national park when you did not drive.
Khao Yai is a case where getting there is easy and getting around is hard. Reaching the gateway town of Pak Chong is cheap and there are plenty of options, but inside the national park there is no public transport, and the viewpoints, waterfalls and trails are tens of kilometres apart. The decision that matters is not "how do I get there" but "how will I move once I arrive".
Getting to Pak Chong
| Option | Time | Departs from | Notes |
|---|---|---|---|
| Train | About 3–4 hours | Krung Thep Aphiwat Central Terminal | Almost every northeastern service (Nakhon Ratchasima, Ubon, Nong Khai lines) stops at Pak Chong |
| Minivan | About 2.5–3 hours | Mo Chit 2 | Can drop you in Pak Chong or near the park road on request |
| Northeastern bus | About 3 hours | Mo Chit 2 | Buses to Khorat or Khon Kaen pass Pak Chong; tell the ticket seller you are getting off there |
| Self-drive | About 2.5–3 hours | – | The option that makes the trip easiest |
The train: comfortable, with early and late departures
Every northeastern line passes Pak Chong, so you can choose a morning rapid train or an evening express. Second-class air-conditioned seats are comfortable for the three hours, and you avoid the Mittraphap Highway traffic on long weekends. The drawback is that Pak Chong station is in the district town, about 25 km from the park checkpoint, so another ride is needed.

The real problem: transport on the ground
Without your own car, three approaches work in practice.
- Songthaew Pak Chong → park checkpoint. These shared pick-ups run from the town to the checkpoint only and do not enter the park. From there you hitch or wait for passing vehicles, which is unreliable. Fine if you are staying on Thanarat Road and just want a short look.
- Charter a songthaew or pick-up for the day. Negotiate in Pak Chong or ask your accommodation to arrange it. Covers the viewpoints, Haew Suwat waterfall and the short trails in one day, and is good value split between several people.
- Rent a scooter in Pak Chong. For confident riders on a clear day. Park roads are steep and twisting, and fog is common in the early morning and late in the rainy season.
Where to stay
- Thanarat Road (the road up to the park) has the resorts, restaurants and farms, and is close to the checkpoint, but there is nothing to do on foot.
- Inside the park (bungalows or camping) suits people who want wildlife at dawn and dusk. Book ahead through the national parks department; there are no large shops inside.
- Pak Chong town is cheap and close to the station, but far from the Khao Yai atmosphere.
Common mistakes
- Arriving in Pak Chong expecting a bus into the park. There is none. Sort out transport before you leave Bangkok.
- Turning up on a long weekend without a booking. Thanarat Road accommodation sells out fast, and rates are several times the weekday price.
- Riding up at dawn on a scooter. Thick fog, slippery roads and animals crossing.
Summary
In a group of three or four, take the train or a minivan to Pak Chong and charter a vehicle for the day; it is the cheapest and easiest formula. Travelling solo or as a couple without a car, choose accommodation that offers park transport or tours. Do not arrive planning to "figure it out there".
