Quick Answer
The best way to travel from Nan Airport (NNT) to Si Nan National Park is a combination of train and bus, offering the optimal balance of cost, scenery, and reliability. Total travel time is 5-7 hours, and the total cost ranges from 300 to 800 THB per person. The journey requires a transfer at Nan Railway Station and a key transport hub like Den Chai or Phrae. For the most budget-conscious, a public bus is the cheapest (under 400 THB), while for groups or those with heavy luggage, a pre-booked private transfer, though costly (2,500-4,000 THB), is the most convenient.
Train from Nan Airport to Si Nan National Park: A Scenic & Authentic Journey
Taking the train is the most recommended method for travelers seeking an authentic Thai experience with a balance of comfort and value. It is not a single direct service but a connected journey through Thailand's rural north.
Step-by-Step Guide:
- Nan Airport (NNT) to Nan Railway Station: No direct rail link exists. Take a local white songthaew (shared taxi) right outside the terminal (30-40 THB, 25 mins) or a metered taxi (200-250 THB, 20 mins).
- Train from Nan Station: Nan is on a local spur line. You must take a train to a mainline junction.
- Option A (Recommended - More Connections): Take a train from Nan to Den Chai Junction. This is a slow, scenic local train (3-4 hours, ~50 THB for 3rd class).
- Option B (Less Frequent): Take a train from Nan to Uttaradit (approx. 4-5 hours).
- Connection to Si Nan National Park: From Den Chai or Uttaradit, take a local bus or songthaew to the town nearest your park entrance (e.g., towards Phrae). Final leg is a local songthaew (50-100 THB) to the park gates.
Train Types & What to Expect:
| Route Segment | Train Type / Class | Duration | Approx. Fare (THB) | Notes |
|---|---|---|---|---|
| Nan -> Den Chai | Ordinary / 3rd Class | 3-4 hrs | 40-60 | Basic seating, fans, open windows, stops frequently. Pure local experience. |
| Nan -> Uttaradit | Rapid / 3rd Class Fan | 4-5 hrs | 80-120 | Slightly faster, reserved seating possible. Still no air-con. |
JR Pass Note: Japan Rail Passes are not valid in Thailand. Thailand's own State Railway Pass is designed for tourists but is economically inefficient for this short regional trip. Point-to-point tickets are advised.
Luggage: Ample space for backpacks and suitcases on overhead racks and at the end of carriages on local trains.
Flying from Nan Airport: Is It Worth It?
Flying might seem logical, but for reaching Si Nan National Park, it's often the least efficient choice in terms of total door-to-door time and cost.
The Reality of “Door-to-Park” Time:
There are no airports at Si Nan National Park. The closest major airport is Chiang Mai (CNX), which is still 3-4 hours by road from the park.
- Flight (NNT to CNX): 1 hour airborne + 1.5-2 hours for check-in/security at NNT.
- Airport Transfer: 30-60 minutes from CNX airport to Chiang Mai Arcade Bus Terminal.
- Bus to Park Region: 3-4 hours from Chiang Mai to the nearest park gateway.
- Final Local Transport: 30-60 minutes by songthaew.
Total Estimated Time: 6.5 to 9+ hours, which is comparable to or longer than the train+bus option, and significantly more expensive.
Cost Breakdown (One Way):
- Flight (NNT-CNX): 1,500 – 3,500 THB (varies by airline & booking time).
- Taxi CNX to Bus Terminal: 200-300 THB.
- Bus to Park Region: 150-250 THB.
- Songthaew to Park: 50-100 THB.
- Total: 1,900 – 4,150+ THB.
Verdict: Only consider flying if your itinerary already includes a stop in Chiang Mai. As a direct transfer method, it is not recommended due to its high cost, multiple legs, and lack of time savings.
Bus from Nan Airport to Si Nan National Park: The Budget Champion
For travelers prioritizing cost above all else, the public bus system is your best friend. It's the cheapest method, though it requires patience and tolerance for multiple changes.
Step-by-Step Bus Route:
- Nan Airport to Nan Bus Terminal (Terminal 2): Take the local white songthaew (30 THB) heading towards the city. Ask for “Bor Kor Sor 2”.
- Long-Distance Bus to Gateway City: At the terminal, find buses bound for Phrae or Uttaradit. These run frequently from 6:00 AM to 5:00 PM.
- Nan to Phrae: ~2.5-3 hours, 120-180 THB.
- Final Connection to the Park: From Phrae Bus Terminal, take a local songthaew or a dedicated minibus (if available) to Si Nan National Park. This journey takes about 1-1.5 hours and costs 80-150 THB.
Night Bus Considerations:
There are no direct night buses from Nan to the park. You could take a late bus to Phrae and stay overnight there before proceeding in the morning. Do not count on arriving at the park entrance late at night as no transport will be available.
Key Advantages & Tips:
- Cost-Effective: Total cost is typically under 400 THB.
- Luggage: Stored under the bus. Weight limits are generous for standard backpacks/suitcases.
- Booking: You can purchase tickets at the Nan Bus Terminal counter. For peace of mind during holidays, book one day in advance.
- Comfort: Basic, reclining seats on standard buses. Bring a jacket as air-conditioning can be strong.
Taxi & Private Transfer: Door-to-Door Convenience at a Premium
This is the most straightforward but also the most expensive option by a significant margin. It eliminates all transfers, waiting, and luggage hauling.
Options & Pricing:
- Metered Taxi (Rare): You might find a taxi at NNT willing to do the long trip on the meter. The fare would be exorbitant (likely 3,500+ THB) and drivers are often reluctant.
- Pre-Booked Private Car/Van: The recommended method. Book online or via your hotel.
Vehicle Type Approx. Price (THB) Travel Time Best For Sedan (up to 3 pax) 2,800 - 3,500 3.5 - 4.5 hrs Couples, small families Minivan (up to 9 pax) 3,500 - 4,500 3.5 - 4.5 hrs Groups, families with lots of gear
When is it Worth It?
- Late-Night/Early-Morning Flights: When public transport is not operating.
- Groups of 4 or More: Splitting the cost can make it comparable to train/bus tickets per person.
- Travelers with Mobility Issues or Excessive Luggage: Eliminates all physical challenges of transfers.
- Tight Schedule: Provides the most predictable travel time.
Booking Tip: Use reputable local tour companies or global platforms like Klook or Viator for pre-booking to ensure fixed rates and reliable service.

Traveler Insights & Pro Tips for a Smooth Journey
Beyond schedules and fares, here's practical wisdom from experienced travelers to save you time, money, and stress.
Luggage Strategy is Key:
- Use a Luggage Forwarding Service: If you have large suitcases, consider using a service like “Takkyubin” (available at 7-Eleven or dedicated offices) to send your main luggage from Nan Airport directly to your accommodation near the park. Travel with just a daypack on the trains/buses. Cost: ~200-400 THB per piece.
- Pack Light & Use Backpacks: If you keep your luggage, backpacks are infinitely easier to manage during multiple transfers than wheeled suitcases on uneven platforms and bus steps.
Master the Transfers:
- Nan Station is Small: Don't worry about getting lost. Arrive 30-45 minutes before your train's departure to buy tickets comfortably.
- Den Chai Junction: This is a simple, small station. The bus stop for connections to Phrae is directly outside the station entrance. Ask the train conductor or station staff to point you in the right direction.
Timing & Seasonality:
- Avoid Thai Holidays: During Songkran (April) or New Year, buses and trains sell out. Book transport as far in advance as possible.
- Start Early: Aim to catch the first transport out of Nan (by 8 AM) to ensure you complete all connections and arrive at the park with daylight to spare for check-in and orientation.
- Weather Contingency: In the rainy season (July-Oct), road travel can be slower. Allow extra buffer time in your schedule.
Essential Apps & Phrases:
- Google Translate (Offline Thai): Invaluable for reading signs and communicating with drivers.
- Transport Apps: “12Go.Asia” is excellent for checking schedules and booking some bus/train/ferry tickets in Thailand.
- Key Phrase: “Pai Si Nan National Park dai mai?” (Can I go to Si Nan National Park?).
FAQs: Getting from Nan Airport to Si Nan National Park
Is there a direct train from Nan Airport to Si Nan National Park?
No, there is no single direct train. The journey requires a multi-step process: first, take a local bus or taxi from Nan Airport (NNT) to Nan Railway Station (approximately 20-30 minutes). From there, you will need to take a combination of regional trains and possibly a bus to reach the park entrance. The most common routing involves trains to a major hub like Den Chai, followed by a connecting bus to the park region.
What is the cheapest way to travel from Nan Airport to Si Nan National Park?
The cheapest option is by public bus. From Nan Airport, take the local shuttle bus (around 30 THB) to Nan Bus Terminal. From there, direct buses run to the town nearest Si Nan National Park (usually Phrae), costing between 150-250 THB. A final local songthaew (shared taxi) to the park entrance will cost about 50-100 THB. Total cost is typically under 400 THB.
Is it faster to fly or take the train?
For the entire door-to-door journey, flying is rarely faster and often more complicated. While a flight from Nan to Chiang Mai (CNX) takes about 1 hour, you must add: 1) Pre-flight time at NNT, 2) Transfer from CNX airport to Chiang Mai bus terminal, 3) A 3-4 hour bus ride to the park region. Total: 6+ hours. A well-planned train+bus combo from Nan can take a similar 5-7 hours but is often more scenic and cost-effective.
Can I use a Thailand Rail Pass for this journey?
The State Railway of Thailand's Rail Pass is primarily for long-distance travel on main lines. Since the journey from Nan involves regional/local trains and buses, the pass offers limited to no value. The cost of local trains from Nan is very low (e.g., Nan to Den Chai: ~50-100 THB), so purchasing individual tickets is more practical and economical for this specific route.
What should I do if my flight arrives late at night?
Options are very limited after ~8 PM. 1) Pre-book a taxi/private transfer: This is the most reliable but expensive option (2,500-4,000 THB). 2) Stay overnight in Nan: Book a hotel near the airport or in town, and start your journey fresh the next morning. Public buses and most trains do not operate late at night.
Is the journey suitable for families with young children or a lot of luggage?
It can be challenging. The multiple transfers with luggage and children are strenuous. Recommendations: 1) Use a luggage forwarding service to send bags directly to your park accommodation. 2) Consider a private van hire for door-to-door convenience for groups. 3) If using trains, pack light and use backpacks.
How many transfers are involved in the train+bus route?
A minimum of 3-4 transfers: 1) Airport to Nan Station (Bus/Taxi), 2) Train from Nan to a junction like Den Chai, 3) Local bus from the train station to the park's province (e.g., Phrae), 4) Final songthaew/taxi from the bus terminal to the specific park entrance. Schedules are not perfectly synchronized, so expect waiting time.
Should I book train and bus tickets in advance?
Yes, especially during Thai holidays (Songkran, Loy Krathong) and weekends. While trains from Nan are rarely sold out, connecting buses from hubs like Phrae to the park can fill up. You can book State Railway of Thailand tickets online via their official D-Ticket website 1-90 days in advance. For buses, booking at the terminal a day ahead is usually sufficient.
