Pai in December and January: Cold Nights, Viewpoints and the Mae Hong Son Loop Road

Pai in December is at its most popular with Thai travellers, and that changes how you should plan: book rooms early for the New Year period, pack for nights that are colder than most people expect, and leave the viewpoints for the early morning. Pai is a small valley town in Mae Hong Son province, about three hours by road from Chiang Mai along a famously winding mountain route. In December and January the days are bright and pleasant, the mornings often bring mist to the valley, and the town fills up around the holidays. This guide covers what the cool season is like, how to get there without a bad trip, the viewpoints worth an early alarm, and how Pai fits into the longer Mae Hong Son loop.

Pai in December and January: what to expect

The cool season in northern Thailand runs from about November to February, and December and January are the coldest part of it. In Pai, that means:

• Warm, sunny days. Daytime is comfortable for walking, riding and sitting at viewpoints. T-shirt weather is common in the afternoon.
• Cold nights and early mornings. The valley traps cold air overnight. Many budget bungalows have no heating and thin walls, so a warm layer and good blanket matter more than you might think.
• Morning mist. On many mornings the valley fills with mist that burns off by mid-morning. This is why the sunrise viewpoints are so popular.
• Crowds around holidays. Thai visitors come in large numbers over New Year and long weekends. Rooms, rental scooters and minivan seats can sell out.

If you want the cool weather without the busiest days, aim for early December or the second half of January. February is still cool at night, but haze from seasonal burning can start to build later in the month. Our guide to the Chiang Mai burning season explains why the north is best avoided from around March if you care about clean air.

Getting to Pai from Chiang Mai

Pai is reached by road on Highway 1095, which climbs and drops through the hills between Chiang Mai and Pai. The route is often described as having 762 curves. Whatever the exact number, it is a slow, twisting drive of around three hours, and many people feel motion sick.

Minivan. The most common option. Prempracha runs hourly minivans from Chiang Mai's Arcade bus terminal during the day, and Aya Service offers vans with hotel pickup in Chiang Mai. Book a day or two ahead in the cool season and further ahead for New Year. Fares are low, but prices vary between the counter, official websites and agents, so compare before you pay.

Private car or driver. More expensive, but you can stop when you want, which helps a lot with motion sickness. It also lets you visit viewpoints and hot springs on the way.

Scooter. Popular with experienced riders, but this is not a good road to learn on. The hills are steep, the bends are tight and there are trucks and vans. If you have not ridden a scooter on mountain roads before, take the van.

Flights. There were no scheduled flights to Pai when we checked. An airline had announced plans for new routes in northern Thailand that included Pai, but they were postponed while awaiting airport approval. Do not build a trip around a flight that is not yet on sale.

Tips for the van ride:

• Sit near the front if you can.
• Eat lightly before you leave.
• Take motion sickness tablets before departure, not halfway through.
• Ask the driver to stop if you feel unwell; they usually take a short break midway.

The viewpoints and sights worth getting up for

Most of Pai's best-known sights are outside the small town centre, so you need a scooter, a bicycle for the flatter routes, or a hired driver.

Yun Lai Viewpoint

A hill on the western side of the valley, close to the Chinese village of Santichon. It is the classic sunrise spot. Thailand's tourism authority lists a small entry fee that includes tea or coffee, and it opens before dawn. In the cool season, arrive by about six to watch the mist sitting in the valley as the sun comes up. It gets busy on holidays, so arriving earlier gets you a better spot.

Pai Canyon

A set of narrow sandstone ridges south of town, just off the main road to Chiang Mai. Entry is free. Sunset is the popular time, and the ridges get crowded then. Some paths are narrow with steep drops and no railings, and the ground is slippery after rain. Wear shoes with good grip and stick to the wider sections if you are not confident.

Other easy stops

• The bamboo bridge (Kho Ku So): a long walkway across rice fields to a small temple. Morning light and fewer people make early visits nicer.
• Wat Phra That Mae Yen: the white Buddha on the hill east of town, reached by a long flight of steps or a road to the top. Good at sunset.
• Hot springs: a warm soak is a good way to end a cold morning. Check entry rules and fees when you arrive.
• The walking street: the evening market in the town centre is busy every night in the cool season, with street food and stalls.

A 3-day Pai plan for the cool season

This plan uses early mornings for viewpoints, slow middays and evenings in town. Our 3 days in Pai sample trip follows a similar pattern. Copy it into RoamerPlanner and adjust it to your arrival time.

Day 1: arrive and settle

• Morning: Minivan from Chiang Mai.
• Afternoon: Check in, rent a scooter if you plan to ride, and walk around the town centre.
• Evening: Walking street for dinner. Go to bed early.

Day 2: sunrise and the east side

• Dawn: Yun Lai Viewpoint for sunrise and mist.
• Morning: Santichon village, then back into town for breakfast.
• Afternoon: Rest, or visit a hot spring.
• Sunset: Wat Phra That Mae Yen, the white Buddha.

Day 3: fields and the canyon

• Morning: The bamboo bridge and the rice fields around it.
• Afternoon: Cafes, a massage or a rest.
• Sunset: Pai Canyon. Leave a bit before dark so you are not riding back on unlit roads.

Pai and the Mae Hong Son loop

Pai is the first stop on the Mae Hong Son loop, a circuit of mountain roads through Thailand's north-west. The usual direction is Chiang Mai to Pai, then on to Soppong and Mae Hong Son town, and back to Chiang Mai via Mae Sariang and the long southern road. Across the whole loop the number of bends is in the thousands, which gives you an idea of how slow the driving is.

Things to know before you commit:

• Allow at least five days for the full loop by car, and more on a scooter. Shorter versions are very tiring.
• Distances are short, times are long. Mountain roads are slow, and fog can reduce visibility in the early morning.
• Fuel and cash: fill up when you can and carry some cash for small towns.
• Insurance: check that your travel insurance covers riding a scooter, and that you have the right licence. Many policies do not cover riding without one.

Where to stay

• In or next to the town centre: best if you do not ride. You can walk to the walking street and restaurants. It can be noisy at night.
• Just outside town: bungalows in the fields are quieter and have views, but you need transport. They can be the coldest places to sleep in December.
• What to check: whether rooms have hot water, extra blankets and a closed window. These matter more in the cool season than a pool.

What to pack for Pai in the cool season

• A warm layer, such as a fleece or a light down jacket, for early mornings and riding.
• Long trousers and socks for the evenings.
• Shoes with grip for Pai Canyon.
• Motion sickness tablets for the road in and out.
• A scarf or buff for dust and cold air on a scooter.

Combining Pai with the rest of northern Thailand

Most people visit Pai as part of a trip based in Chiang Mai. Our guide to Chiang Mai in December and January covers the city itself, and our 3 days in Chiang Mai itinerary is a good start before heading into the hills.
