There are several practical ways to reach Nan. The best one depends less on finding a single “correct” route and more on where the traveller is starting, how much time is available and whether the journey itself is part of the trip.
Flying from Bangkok — Usually the Simplest Option for Limited Time
For travellers arriving through Bangkok, flying is usually the most straightforward way to reach Nan quickly. Nan Nakhon Airport is in Mueang Nan District, so arriving by air brings travellers directly into the provincial capital rather than requiring another long overland transfer.
Direct Bangkok–Nan services are currently offered from Don Mueang Airport by Thai AirAsia and Nok Air. Flight schedules and frequencies can change, so I would still check the airline directly before fixing the rest of the itinerary.
If time in Nan is limited, flying from Bangkok usually protects more time for the province itself.
Arriving at Nan Nakhon Airport
For me, one advantage of flying into Nan is that the arrival feels simple. The airport is already in the Nan Town area, which makes it easier to begin with the old town, collect a vehicle or meet a driver before travelling farther into the province.
Do Not Build a Tight Mountain Transfer Immediately After Landing
If the flight arrives later in the day, I prefer not to make the first afternoon depend on reaching Doi Phu Kha, Bo Kluea or Sapan before dark. Staying in Nan Town first can make the beginning of the trip calmer and leaves more flexibility if the flight is delayed.
Travelling from Chiang Mai — Overland Can Make More Sense
Chiang Mai and Nan are both in northern Thailand, but they are separated by a substantial overland journey. For travellers already in Chiang Mai, a bus, private transfer or self-drive journey can be more practical than routing back through Bangkok by air.
GreenBus currently operates Chiang Mai–Nan services, with departures listed from Chiang Mai Bus Terminal 3 and services to Nan Bus Terminal. Timetables can change, so I would check the operator again close to the travel date.
Think About the Whole Door-to-Door Journey
A flight is not automatically faster once airport transfers, check-in time and connections are included. From Chiang Mai, an overland journey can sometimes be the simpler decision even though the road itself takes several hours.
Long-Distance Bus from Bangkok — Useful When Time Is Less Important
Long-distance buses connect Bangkok and Nan, including services operated by established intercity companies. This can work well for travellers who prefer an overnight journey or want to avoid the cost of flying.
Nakhonchai Air currently lists a Bangkok–Nan route, and Sombat Tour also publishes Bangkok–Nan services. I would treat exact departure times and fares as changeable information and confirm them with the operator before booking.
The bus can save a hotel night, but it also uses more physical energy than a short flight.
Driving to Nan — More Freedom, More Responsibility
Driving can make sense for travellers who want flexibility after arriving in the province, especially if Pua, Doi Phu Kha, Bo Kluea, Sapan or other mountain areas are part of the trip.
The advantage is not simply having a car. It is being able to stop, change pace and decide how much time to spend between destinations.
The trade-off is that the driver has to manage fatigue, unfamiliar roads and the transition from long-distance driving to mountain routes.
Do Not Treat the Drive to Nan and a Mountain Day as the Same Day
After a long drive into the province, I would be cautious about immediately adding several hours of mountain roads. A quieter first evening in Nan Town can make the following days more enjoyable.
Private Transfer — Useful for Groups or Travellers Who Do Not Want to Drive
A private transfer can make sense for families, small groups, travellers carrying more luggage or anybody who wants the flexibility of road travel without driving personally.
The value is usually in convenience rather than simply speed. A private vehicle can connect the arrival point, accommodation and later mountain travel with fewer changes.
What About the Train?
Nan does not have a railway station. Travellers using Thailand's rail network need to continue by road from another city or station.
For most short trips, I find it easier to compare a direct flight, bus or road transfer rather than build the journey around a train connection unless rail travel is part of the experience the traveller wants.
Which Option Would I Choose?
If somebody has only a few days in Nan and is starting in Bangkok, I would normally look at flying first. If the traveller is already in Chiang Mai, I would compare bus, private transfer and self-drive rather than assume flying is automatically better.
For a group planning several days around the mountains, having a suitable vehicle after arrival can become more important than the way they reached Nan in the first place.
Before Booking, Check These Details
- Where the journey actually starts: Bangkok, Chiang Mai or elsewhere
- Arrival time in Nan, not only departure time
- Whether a mountain transfer is planned on the same day
- Current airline or bus timetable
- Baggage and equipment requirements
- Whether a vehicle will be needed after arrival
- Return transport, especially during holidays
One Final Thought
Getting to Nan is part of the planning, but it does not need to dominate the trip. I usually prefer the option that leaves enough time and energy to experience the province after arrival.
The fastest route on paper is not always the easiest journey. I would choose the connection that fits the traveller's time, energy and plans after reaching Nan.
