Doi Inthanon is Thailand’s highest point, and it’s close enough to Chiang Mai that it’s a genuinely easy day trip rather than an expedition. You can be standing at 2,565 meters, jacket zipped up against the cold, by mid-morning, then back in the city for dinner.
This guide covers what the park actually costs to enter, how people get there (tour vs. self-drive), the sights worth building a day around, and the one thing almost every first-timer underestimates: how cold the top of the mountain actually gets. Every price and fact below is sourced and dated; see the Sources section for what we used.
What is Doi Inthanon National Park?
Doi Inthanon is a national park built around Thailand’s highest mountain, also called Doi Inthanon, which reaches 2,565 meters (8,415 feet) above sea level, according to Wikipedia and Thai National Parks. The mountain and park are named after Inthawichayanon, a former Chiang Mai prince who worked to protect the region’s forests; his remains were interred here after his death, and the peak was renamed in his honor.
Beyond the summit itself, the park covers waterfalls, cloud forest, hill-tribe villages, and one of northern Thailand’s better short hikes (Kew Mae Pan, covered below). It sits in Chom Thong District, part of Chiang Mai province, which is why it shows up on nearly every “best day trips from Chiang Mai” list. If you’re weighing it against other nearby options, see outthailand.com’s things to do in Chiang Mai guide for how it stacks up, or the Pai from Chiang Mai guide if you’re deciding between a mountain day trip and a multi-day trip north.
How to get to Doi Inthanon from Chiang Mai
The park entrance is roughly 80-100km from Chiang Mai city center, and the drive takes about 1.5-2 hours each way, per multiple route-planning sources including Rome2Rio and Chiang Mai Traveller. The route is straightforward: south out of the city on Highway 108, then onto Route 1009, which climbs all the way to the summit area on a paved, well-maintained road. You don’t need a 4x4; a standard sedan or a scooter in good condition can manage it.
Organized tour. The simplest option, especially for a first visit. A shared full-day tour from Chiang Mai commonly runs around ฿1,400 (US$42) per person, according to Bon Voyage Thailand, typically departing around 8am and returning by 5:30pm. Tours usually bundle a guide, lunch, hotel pickup, and sometimes the entrance fees, though check whether fees are included or paid in cash on the day, since pricing structures vary by operator.
Self-drive (car or scooter). Cheaper if you’re already comfortable driving in Thailand, and it gives you control over how long you linger at each stop. The road is in good condition, but expect a real temperature drop and possible fog on the way up, especially early morning or after rain, so headlights and a bit of caution on the switchbacks matter more here than on flat city roads. See outthailand.com’s getting around Chiang Mai guide for scooter rental basics and license requirements before you commit to riding rather than driving.
There’s no public bus route that conveniently covers the whole park (its sights are spread across many kilometers of mountain road), so independent travelers without their own vehicle generally still end up booking transport, whether that’s a private driver, a shared tour, or a rented car.
Entrance fees for foreigners
The national park charges a standard entrance fee plus a separate vehicle fee, and the Twin Pagodas charge their own fee on top of that. According to Thai National Parks and confirmed by current tour operator pricing pages:
| Fee | Price (THB) | Price (USD) |
|---|---|---|
| Park entrance, foreign adult | ฿300 | $9 |
| Park entrance, foreign child (3-14) | ฿150 | $4.50 |
| Vehicle fee, car | ฿30 | $0.90 |
| Vehicle fee, motorbike | ฿20 | $0.60 |
| Twin Pagodas (separate, not covered by park ticket) | ฿100 | $3 |
| Kew Mae Pan guide fee (per group, up to 10 people) | ~฿200 | ~$6 |
Conversions at ฿33 = US$1 (July 2026). Pay in cash at the park gate; card payment is not reliably available at the entrance booths. If you’re on a tour, confirm in advance whether these fees are included in the tour price or paid separately on the day, since both models are common.
Top sights in Doi Inthanon National Park
Most day trips combine four or five of these, since they’re spread along the same mountain road and can be visited in sequence.
| Sight | What it is | Note |
|---|---|---|
| Twin Royal Pagodas (Napamethinidon & Napaphonphumisiri) | Two chedis built in 1987 and 1992 to honor the 60th birthdays of King Bhumibol and Queen Sirikit | Separate ฿100 ($3) entry fee; gardens and viewpoints around each pagoda, often the most photographed stop in the park |
| Wachirathan waterfall | A wide, roughly 40-meter waterfall close to the main road | Easy to reach, one of the most visited falls in the park; can get crowded midday |
| Summit and Ang Ka nature trail | The literal highest point in Thailand (2,565m), with a short boardwalk loop through mossy cloud forest to a summit marker | Flat, easy walk, but cold and often misty; bring a jacket |
| Kew Mae Pan trail | A roughly 2.5-3km circular ridge trail at about 2,200m with some of the park’s best panoramic views | Open November 1-May only, closed in rainy season; compulsory local guide, about ฿200 ($6) per group of up to 10 |
| Ban Mae Klang Luang | A Karen hill-tribe village known for terraced rice paddies and shade-grown coffee | About 90 minutes from Chiang Mai; rice terraces are most scenic toward the end of the rainy season (September-October) |
The Twin Pagodas
Napamethinidon and Napaphonphumisiri sit on a ridge with landscaped gardens and, on a clear day, wide views over the surrounding hills. They were built to mark the 60th birthdays of the previous king and queen and are jointly run separately from the national park itself, which is why they carry their own ฿100 entrance fee rather than being covered by your park ticket.
Wachirathan waterfall
A roughly 40-meter waterfall a short walk from the road, with food stalls and seating nearby. It’s one of the more accessible falls in the park, which also makes it one of the busier stops, especially around midday when tour buses cluster.
The summit and Ang Ka boardwalk
The actual highest point in Thailand isn’t a dramatic peak with a view. It’s a boardwalk loop through dense, mossy cloud forest (the Ang Ka nature trail) that passes a marker and sign confirming you’re at 2,565 meters. The appeal here is the forest itself and the novelty of the elevation, not a panoramic vista, since the summit area is often shrouded in mist.
Kew Mae Pan trail
Widely rated the best hike in the park: a circular ridge trail at around 2,200 meters with open views that the summit boardwalk doesn’t offer. It’s only open November 1 through May, closed June-October during the rainy season, according to Chiang Mai Traveller. Every visitor must hire a local guide, usually from the Karen or Hmong hill-tribe communities, at roughly ฿200 for a group of up to 10 people. Plan on 2-3 hours for the full loop.
Ban Mae Klang Luang
A Karen (S’gaw Karen) hill-tribe village about six kilometers from the park headquarters, roughly 90 minutes from central Chiang Mai. It’s known for terraced rice paddies that are most photogenic toward the end of the rainy season (roughly September into mid-October, when morning fog often settles over the terraces) and for locally grown, shade-cultivated coffee, sold under a few different village-based brands. It’s a good stop for a slower, village-level contrast to the park’s nature-focused sights.
The summit is genuinely cold, not just “cooler”
This is the detail most first-time visitors underestimate. Doi Inthanon’s upper sections sit above 2,000 meters, and the temperature there is a real, noticeable drop from Chiang Mai city, not a mild breeze. Winter mornings, especially December and January, can approach freezing, and ground-level frost has been recorded on the coldest mornings in recent winters. Even outside the coldest months, the summit and Kew Mae Pan trail stay markedly cooler and windier than anywhere in the city on the same day.
Bring a real jacket or fleece, not just a light layer, especially if you’re visiting between November and February or hoping to catch sunrise. Chiang Mai’s own weather that same morning is not a useful guide to what you’ll feel at the top.
Best time to visit and sunrise
The dry season, roughly November through February, is the best all-around window: clearer skies, the Kew Mae Pan trail open, and the coolest, crispest air of the year (which is also the coldest, so plan your layers accordingly). This overlaps with Chiang Mai’s broader high season; see outthailand.com’s best time to visit Chiang Mai guide for how Doi Inthanon’s dry season lines up with the city’s own smoke-season and rainy-season patterns.
Sunrise at the summit is possible but isn’t part of most standard day tours, which tend to depart Chiang Mai around 8am. Catching it means either driving up yourself in the dark and cold, or booking a tour specifically built around sunrise. If sunrise matters to you, confirm the departure time before booking rather than assuming a “Doi Inthanon day tour” includes it.
Tour or independent: which should you choose?
Choose a tour if: it’s your first visit, you don’t want to drive mountain roads in cool, sometimes foggy conditions, or you’d rather have entrance fees, a guide, and lunch handled for you in one price. A shared group tour running around ฿1,400 ($42) per person is a reasonable trade for not thinking about logistics.
Choose self-drive if: you want to set your own pace, stop longer at whichever sight you like best, or you’re already comfortable driving or riding in Thailand and want to save the tour markup. Just budget realistically for the entrance fees, the Twin Pagodas fee, and the Kew Mae Pan guide fee if you plan to do that trail, since none of those disappear just because you’re driving yourself.
Either way, this pairs naturally with a broader look at how to move around the region: see outthailand.com’s getting around Chiang Mai guide for scooter and car rental basics, and the things to do in Chiang Mai guide for how a Doi Inthanon day trip fits alongside the city’s other sights.
Planning the rest of your trip
Once Doi Inthanon is on the itinerary, check outthailand.com’s Chiang Mai events calendar for what else is happening the same week, whether that’s a market, a live music night, or a workshop worth building the rest of your days around. It’s useful for slotting a mountain day trip into a broader week in the city rather than treating it as a one-off errand. If you’re comparing this against other day trips, outthailand.com’s ethical elephant sanctuary guide covers the other most-booked full-day option out of Chiang Mai.
