Before you plan a Khon Kaen trip, the first thing to sort out is how you'll get there and how you'll move around once you arrive. The good news is Khon Kaen has options for every budget: a one-hour flight from Bangkok, a relaxed train ride, an overnight bus, or driving yourself up the Mittraphap Highway. On this page we compare the time, price, and pros and cons of each.
Quick rundown of your options to Khon Kaen
If you want to decide fast, here's the overview of each way to get there from Bangkok. Pick based on whether you care most about time, money, or the flexibility to stop along the way.
- Flight — fastest, around 1 hour in the air, tickets from a few hundred to low four-figure THB. Best if you're short on time.
- Train — slow but relaxed, and it drops you right in the city centre. Around 7–8 hours. Best if you enjoy the ride and the scenery.
- Bus — cheap, with lots of departures day and night. Around 6–7 hours, tickets roughly 380–600 THB.
- Drive yourself — the most flexible, with stops in several provinces along the way. Around 450 km up the Mittraphap Highway, roughly 6–7 hours.
How to choose
Short 2–3 day trip? Fly — the time you save is worth it · Several days, or want to stop in Korat or Pak Chong on the way? Drive yourself · Tight budget and not in a rush? Take an overnight bus and you'll wake up right as you arrive.
Flying into Khon Kaen Airport (KKC)
Khon Kaen Airport (code KKC) is only about 6 km from the city, which is a real advantage — getting into town is quick and cheap. Flights from Bangkok run out of both Don Muang and Suvarnabhumi, take around 1 hour, and several airlines fly the route, so fares stay fairly competitive.
- Airlines on this route — AirAsia, Thai Lion Air, Nok Air, Thai Airways, and Bangkok Airways, with several departures a day to choose from.
- Fares — budget carriers start in the low hundreds of THB if you book ahead; typically around 700–1,500 THB one way, more during holiday periods.
- Flight time — about 1 hour, plus check-in and baggage; even so, far quicker than going overland.
- Location — the airport sits within the city limits, so you can reach the centre in around 15–20 minutes.
How to get from Khon Kaen Airport into town
Once you land there are several ways into town — pick based on how many of you there are and how much of a hurry you're in. The distance is short, so nothing costs much whichever way you go.
- City bus / airport bus line — cheapest, with fares from a few baht up to around 40 THB. It runs past the main spots in town, so it's good if you're not rushing and there are only a few of you.
- Metered / airport taxi — there's a counter at the airport; around 100–150 THB into town. Handy if you've got a lot of luggage.
- Grab — book through the app, prices similar to a taxi, around 100–150 THB to the city centre. Good if your hotel is tucked away.
- Hotel shuttle / transfer — many hotels offer an airport pickup; check when you book. Some are free if you stay several nights.
Money-saving tip
Travelling solo and not in a rush? The city bus is best value — a few baht and you're at the Bueng Kaen Nakhon area · But if there are 3–4 of you, one Grab split between you comes out cheaper and drops you right at the hotel door.
Taking the train to Khon Kaen — the Isan line into town
Khon Kaen sits on the Northeastern (Isan) rail line, which departs from Bangkok's Krung Thep Aphiwat Central Terminal (Bang Sue). The part a lot of people love: Khon Kaen station is right in the city centre, so you can walk or hop in a songthaew straight to your accommodation — no trek out to the edge of town like with the bus.
- Departure point — Krung Thep Aphiwat Central Terminal (Bang Sue); the Isan train passes Korat and Bua Yai before reaching Khon Kaen.
- Travel time — around 7–8 hours depending on the service; the special express is faster than the ordinary train.
- Classes — there's budget-friendly 3rd class with fans, air-conditioned 2nd class, and sleeper cars on the overnight services.
- Who it suits — anyone who loves the feel of a train ride, isn't in a rush, and wants to land right in the centre without a long transfer.
Straight talk
Thai trains run late fairly often, so leave buffer time and don't bank on the schedule to the minute. If you've got a connecting flight or an important evening appointment, flying is the safer bet · But if you want the experience of rolling past the Isan fields, the daytime service is a fun ride.
Buses and minivans — arriving at BKS3
The bus is a popular choice thanks to frequent departures day and night and friendly prices. From Bangkok you board at Mo Chit 2 bus terminal and arrive at the 3rd Bus Terminal (BKS3), which is Khon Kaen's main station these days. It sits on the outer edge of town, so you'll need a short onward ride into the centre.
- Operators on this route — Nakhonchai Air, Cherdchai Tour, Sombat Tour, and BKS 999, with several seat grades to choose from.
- Fares — roughly 380–600 THB depending on the operator and seat class; VIP coaches with wider seats cost a bit more.
- Travel time — around 6–7 hours, with morning departures from about 07:30 right through to late night.
- Destination — you arrive at BKS3 on the edge of town; transfer by songthaew, taxi, or Grab into the Bueng Kaen Nakhon–Si Chan area.
Insider tip
The overnight service is the best use of time — board late, sleep through, and arrive in the morning, saving a night's accommodation too · Book ahead over long weekends, as seats fill fast, especially the VIP coaches.
Driving yourself up the Mittraphap Highway — distance from Bangkok
If you like flexibility, driving yourself is the most freeing option. The main route is the Mittraphap Highway (Route 2), the wide, easy-driving Isan road with rest stops, petrol stations, and restaurants all the way. It's roughly 445–455 km from Bangkok to Khon Kaen, around 6–7 hours of driving including breaks.
- Route — Bangkok–Saraburi–Pak Chong–Nakhon Ratchasima (Korat)–Khon Kaen, mostly along the Mittraphap Highway.
- Distance — about 450 km from Bangkok; it's a main highway, so it's easy to follow with clear signage.
- Driving time — around 6–7 hours, plus a bit extra if you stop around Pak Chong or Korat.
- Stops along the way — Pak Chong, Khao Yai, and Korat are easy places to break for food and rest, or to extend the trip.
Driving it comfortably
The Pak Chong–Khao Yai stretch has hill climbs and bends, so take it carefully, especially at night or in the rain · Stop for a break every 2 hours to stay alert — there are large petrol stations and roadside cafés all along the Mittraphap.
Renting a car in Khon Kaen for trips out of town
Several of Khon Kaen's standout sights sit outside the city — the Phu Wiang Dinosaur Museum, the Ubolratana Dam, and the King Cobra Village at Khok Sa-nga — and public transport to them is awkward. So renting a car makes a lot of sense if you plan to head out of town. There are rental counters both at the airport and in the city.
- Rental prices — small eco-cars from around 480–700 THB a day; mid-size sedans or SUVs around 900–1,500 THB a day.
- Where to pick up — there are counters at Khon Kaen Airport, such as Thai Rent a Car, plus local operators like Chic Car Rent, so you can collect a car straight after you land.
- Documents — you'll need a driving licence and ID card; some operators take a deposit via credit card, others don't require one — check the terms before booking.
- Hire with a driver — if you'd rather not drive, there are day-rate cars with a driver, good for heading out of town as a group.
Worth it or not
If you're only seeing the city, skip the rental — walking and Grab are cheaper · But if you're heading to Phu Wiang or the Ubolratana Dam, a one-day rental beats taking Grab there and back, and gives you far more freedom over your timing.
Getting around Khon Kaen once you've arrived
Central Khon Kaen isn't large — the main sights like Bueng Kaen Nakhon, Wat Nong Waeng, and the food districts are close together and walkable in stretches. So getting around town is easy; just pick whatever's most convenient.
- Songthaew — several lines run around the city, fares from around 10–15 THB. Cheap, but you'll need to learn a little about which routes go where.
- Grab / taxi — easy to call; most in-town trips run around 50–120 THB. Good at night or when you're in a hurry.
- Motorbike rental — nimble for getting around town, from around 200–300 THB a day. Good if you like to ride yourself and reach every back lane.
- Walking — the Bueng Kaen Nakhon–Wat Nong Waeng–walking street zone is comfortably walkable in the cooler evening hours.
Bueng Kaen Nakhon–Si Chan area
City centre, close to food, markets, and the main sights. Stay here and you can walk to plenty without relying much on transport.
Kang Sadan area, near KKU
A cluster of cafés and student-priced spots that chilled-out travellers love, but you'll need a songthaew or Grab to reach the centre.
Around BKS3 on the edge of town
Handy if you arrive by bus and want to stay near the station, but it's far from the in-town sights and you'll need an onward ride.
Which option suits your style — a summary
- Short on time, want speed — fly into KKC, then call a Grab into town; door to door in 2 hours.
- Tight budget, not in a rush — take an overnight bus and save on both the ticket and a night's accommodation.
- Want to stop in several places — drive yourself up the Mittraphap and stop in Pak Chong, Khao Yai, and Korat as you please.
- Lots of out-of-town sights — fly in, then rent a car at the airport to reach Phu Wiang and the Ubolratana Dam easily.
- Only seeing the city — no car needed; walking, songthaews, and Grab have you covered.
