Doi Inthanon Travel Guide 2026
Everything You Need to Know

COSTS

Thai adults pay 60 THB and children 30 THB. Foreign visitors pay 300 THB per adult and 150 THB per child, plus a vehicle fee depending on your ride. Doi Inthanon is a Group 3 park under Thailand’s Department of National Parks.

Child = age 3–14 or under 140 cm tall • Free entry: under 3, Thai seniors 60+, monks and novices, visitors with disabilities

Thai family of 2 adults + 1 child in one car = (60×2) + 30 + 30 = 180 THB

Foreign couple, 2 adults with a rental car = (300×2) + 30 = 630 THB

Hiking Kew Mae Pan? Add a 200 THB guide fee per group (split between up to 10 people)

💡 Keep your entry ticket on you — rangers may ask to see it inside the park.

Foreign travelers — especially expats who live and pay taxes in Thailand — often ask why they pay five times the Thai rate (300 vs 60 THB). It’s a fair question that comes up in plenty of reviews. To be clear: this is the standard two-tier pricing policy applied at national parks across Thailand, not something unique to Doi Inthanon. Knowing this in advance saves an unpleasant surprise at the gate.

⚠️ Fees are revised from time to time, and many blogs still mix in outdated rates. Check the official Doi Inthanon National Park page for the latest before you travel.

WHEN TO GO

The most popular window is November–February (cool weather, sea of mist, and a shot at frost). The rainy season suits travelers who prefer lush green forest, quiet trails, and fewer crowds.

Known locally as “mae kaning,” frost forms when overnight temperatures drop below freezing and coats the grass in white ice crystals — the most searched-for sight of the Thai winter.

When it happens: late November–January, peaking in the coldest stretch from late December through January. In some years, ground temperatures dip to -2 to -3°C.

Where it shows up most: along the Chom Thong–Doi Inthanon road around km 43–44, the summit ranger station at km 46, the Thai National Observatory at km 44, in front of the radar station at the very top, and the Kew Mae Pan viewpoint at km 42.

What time: the ticket gate opens around 5:00 AM. Get to your viewpoint before sunrise — once the sun hits, frost melts fast.

Manage your expectations: frost is a matter of luck, not a daily event. It depends on each night’s conditions. Improve your odds by picking a clear, windless night and checking the temperature forecast in advance.

The viewpoints up here are famous for the sea of mist and sunrise — especially on January 1, when tens of thousands drive up for the first light of the year. If crowds aren’t your thing, skip New Year’s Day and pick a weekday in the same month. The mist is just as beautiful, and the experience is far more comfortable.

Thailand’s “sakura” — the wild Himalayan cherry (nang phaya suea khrong) — blooms from late December to mid-January. The famous spots are the Khun Wang route and the area around the Lady Slipper Orchid conservation project, including the much-photographed “cherry blossom tunnel.” The bloom window is short and shifts every year, so check local pages before you go.

The red rhododendron, the “queen of Inthanon,” blooms once a year from January to March along the Kew Mae Pan trail. The only way to see it is to hike the trail — there’s no road access.

In the rainy season (June–October) the forest turns intensely green, the waterfalls run at full power, crowds thin out, and accommodation is cheaper and easier to find. Perfect for travelers who want peace and quiet — just note that Kew Mae Pan is closed and some paths get slippery, so pack shoes with good grip.

THE MOST-ASKED-ABOUT HIGHLIGHT

Open November 1 – May 31 only, every year (closed through the rainy season so the forest can recover). The 3.2 km loop takes 2–4 hours. Register on arrival (walk-in) at km 42 — a local guide is mandatory at 200 THB per group. You cannot hike it on your own.

📌 Right now (July) Kew Mae Pan is closed. It reopens November 1.

1. Cloud forest — a cool, damp climb through moss- and fern-draped evergreen forest, often wrapped in mist. This is the most strenuous stretch.

2. Semi-alpine meadow + viewpoint — the trees open onto grassland and a wooden platform with a 180-degree view (the trail’s most famous photo spot). The grass is green in the cool season, golden in the hot season.

3. Red rhododendron zone — a cliff-edge walk (fenced) through rhododendron groves that bloom January–March, with Lan Sadet waterfall along the way.

4. Mae Pan stream — a gentle descent to the stream before looping back.

The trail itself is walk-in: sign up and pay the guide fee at km 42 on the day, no advance booking needed. The park entrance gate, however, is a separate system — during extreme peaks (like New Year) the park may run queues or advance registration, so check the park’s page before high-season visits.

The trailhead at km 42 has parking for about 50 cars, food stalls, souvenir shops, and separate men’s and women’s restrooms — but there are no restrooms on the trail, so go before you start and carry water. There’s no accommodation at Kew Mae Pan itself; the nearest places to stay are Ban Mae Klang Luang and Ban Khun Klang.

⚠️ The hike feels harder than it looks — you’re above 2,000 meters, where the thinner air makes you tire faster. Travelers with health conditions should assess before going. If you’re lucky, you may spot a goral, a rare protected mountain species of Himalayan lineage.

WHAT TO SEE

The Highest Spot in Thailand (km 48) — check in at 2,565 meters beside the memorial stupa of King Inthawichayanon. Cold all year round.

Ang Ka Luang Nature Trail — a ~400-meter boardwalk loop through cloud forest around an ancient bog more than 10,000 years old, considered the coldest spot in Thailand: some December–January days hover at 3–4°C. An easy walk for all ages, misty most of the winter, with a real chance of frost.

The Twin Royal Pagodas (Naphamethanidon & Naphaphonphumisiri) — twin chedis built by the Royal Thai Air Force in honor of King Rama IX and Queen Sirikit, set on a ridge with sweeping mountain views and surrounded by cold-climate flower gardens. The park’s most popular photo stop.

Wachirathan Waterfall (formerly Tad Khong Yong) — a single ~70-meter drop around km 20–21, down a ~800-meter side road. Easy drive-up access with restaurants, restrooms, and parking. Thundering in the rainy season with frequent rainbows in the spray; at its best October–April. The sheer Pha Kaew cliff rises just opposite.

Siriphum Waterfall — twin parallel streams tumbling down a high cliff, visible from afar at the Royal Agricultural Station. A beautiful photo backdrop.

Mae Ya Waterfall — broad, curtain-like tiers, often ranked among the most beautiful waterfalls in Thailand. It’s in a separate zone with its own access road (not the summit road), so save it for a trip with extra time.

Pha Dok Siew Waterfall — a small jungle waterfall on a nature trail near Ban Mae Klang Luang, known as a filming location of the Thai movie “Rak Jung.”

Ban Mae Klang Luang — a Karen (Pgaz K’Nyau) village famous for its terraced rice fields. The view transforms three times a year: flooded paddies mirroring the sky in June, deep green in September, and gold in October–November. Homestays and rice-view coffee shops make it worth lingering.

Royal Agricultural Station Inthanon — the 80th Anniversary garden, a rhododendron garden, flower greenhouses, and hydroponic vegetables in wonderfully cool strolling weather.

Pha Ngam (“Two Seasons Cliff”) — a viewpoint where the contrast between seasons is at its sharpest: bare rock faces in the dry months, a sea of mist in the rains.

Huai Kub Kab — a wide-angle sea-of-mist viewpoint over the valley.

Phra That Khun Wang — a hilltop stupa above 2,150 meters, with rhododendrons and white kham khao blossoms in winter.

Hmong Market — cold-climate fruit and vegetables, local products, and souvenirs at friendly prices.

GETTING THERE

From Chiang Mai city, take Highway 108 (Chiang Mai–Chom Thong) to around km 57, just before Chom Thong town, then turn right onto Highway 1009 (Chom Thong–Inthanon) and climb 48 km to the summit. The road is paved the whole way but winding and steep.

Before you climb: check your brakes and fill the tank — fuel stations are scarce on the mountain • On the way down: use low gear to help you brake, and never ride the brakes — they can overheat and fail • Order of stops: attractions line up by km marker (Wachirathan km 20 → Kew Mae Pan km 42 → summit km 48), so visiting in sequence saves real time.

Take the yellow songthaew (shared pick-up bus) from Chiang Mai to Chom Thong first, then charter a second songthaew up the mountain from Wat Phra That Si Chom Thong. This works best in a small group so you can split the charter cost.

1. In the city, catch the yellow Chom Thong-bound songthaew at Chang Phueak Bus Terminal or Chiang Mai Gate (running roughly 8:00 AM–4:00 PM) and get off at Chom Thong town / Wat Phra That Si Chom Thong.

2. The songthaew rank in front of the temple runs charters up the mountain — agree the price and the stops clearly before setting off.

3. Fix a firm pick-up time for the ride back down.

Tips: carry enough cash (some spots have no signal and don’t take transfers), bring warm layers from the start, and team up to split the charter — it’s far cheaper than going alone. This hassle is exactly why many travelers book a tour with hotel pick-up instead.

TOURS & WHERE TO STAY

Day tours start around 1,190–1,200 THB per person at the Thai rate; foreign visitors usually pay the park entrance fee on top. Most tours include hotel pick-up in the city.

1-day tour — the popular program runs: hotel pick-up → a waterfall (typically Wachirathan) → the highest point → Ang Ka Luang boardwalk → the Twin Royal Pagodas → a guided hike to Pha Dok Siew waterfall / Ban Mae Klang Luang → some packages bundle in elephant feeding or bathing → drop-off in the evening.

2-day 1-night cherry blossom tour — the Inthanon–Khun Wang–Khun Chang Khian route, timed for the wild Himalayan cherry bloom.

Before you book, check: is the park entrance fee included (foreigners usually pay extra), how many meals are included, the group size (small groups get more time at each stop), and whether insurance is covered.

The most popular zone is Ban Khun Klang near the park headquarters (km 31), about 10–11 km from Kew Mae Pan. You’ll also find rice-terrace homestays at Ban Mae Klang Luang.

Ban Khun Klang campsites & glamping — the largest accommodation zone on the mountain; wake up and walk straight out to the mist. Rent a tent or pitch your own, from a few hundred THB up to around 2,700 depending on the setup and season.

Ban Mae Klang Luang homestays — rice-terrace views, village atmosphere, and home-cooked local food. Ideal for travelers who want a taste of local life.

Resorts around Chom Thong — comfortable rooms at the base of the mountain, then an easy early-morning drive up.

💡 In winter (especially over New Year) prices climb and everything books out fast — reserve several weeks ahead.

PLAN YOUR TRIP

Day 1: head up late morning → Wachirathan Waterfall → Royal Agricultural Station → check in at Ban Khun Klang / Mae Klang Luang → evening rice-terrace photos and a BBQ dinner in the cool mountain air.

Day 2: pre-dawn sea of mist or frost at Kew Mae Pan or the summit → hike Kew Mae Pan → Twin Royal Pagodas → stop at Mae Ya or Pha Dok Siew waterfall on the way down.

In the rainy season (Kew Mae Pan closed), swap in Mae Ya Waterfall or another nature trail instead.

GET READY

CHECK BEFORE YOU GO

Weather at the summit changes much faster than in the city, and the park occasionally closes trails or waterfalls after heavy rain, strong winds, or for forest recovery. Double-check the night before and again on the morning of your trip — especially if you are planning to chase frost or hike Kew Mae Pan.
