About Doi Inthanon National Park

Located in the Chom Thong District of Chiang Mai Province, Doi Inthanon National Park covers 482 square kilometers (301,184 rai) of the Thanon Thong Chai Range. The terrain climbs from 800-meter lowlands to the 2,565-meter summit of Doi Inthanon. That's the highest point in the country. This steep elevation gradient creates a sharp shift in ecosystems. Mixed deciduous and dipterocarp forests at the base give way to pine and dry evergreen woods, eventually turning into a moist evergreen cloud forest above 1,800 meters.

That high-altitude zone holds Thailand's only sphagnum bog ecosystem. It supports the highest bird diversity of any national park in the country, with 500 to 510 recorded species. Several of these birds don't exist anywhere else in Thailand. The park's terrain also feeds the Ping River watershed. Rainwater channels into the Mae Klang, Mae Ya, Mae Hoi, Mae Chaem, and Mae Tia rivers, dropping over major waterfalls like Wachirathan and Mae Ya.

The Mountain's Royal History

The mountain was originally called Doi Luang, meaning 'great mountain.' It took its current name from King Inthawichayanon, one of the last rulers of Chiang Mai. He advocated for forest conservation in the north. At his request, his remains were interred on the mountain after his death.

Early conservation efforts began here in 1954. Doi Inthanon officially became Thailand's sixth national park on October 2, 1972, with boundaries updated in 1978 and 2009. Decades later, the Royal Twin Pagodas—Phra Mahathat Naphamethanidon and Naphamethanidon—were constructed near the summit. They commemorate the 60th birthdays of King Bhumibol and Queen Sirikit.

Why Visit Doi Inthanon National Park

Walk the Cloud Forest Boardwalk

A raised wooden path loops through Thailand's only sphagnum bog near the 2,565-meter summit. The air stays cold here year-round. You walk through dense moist evergreen forest heavy with mosses, ferns, and high-altitude rhododendrons found nowhere else in the country.

Watch the Sea of Mist

From November to February, a dense fog rolls through the valleys below the pine-dotted ridgeline. The viewpoint near the Kew Mae Pan trailhead offers a clearer sunrise than the misty peak itself. Bring a heavy jacket. Temperatures often drop close to freezing before dawn.

Stand Near Wachirathan Waterfall

This powerful cascade sits just off the main park road. Water crashes over the rocks with enough force to throw a constant mist and frequent rainbows across the viewing area. You only need a short walk from the parking lot to feel the spray.

See the Royal Twin Pagodas

Built for the 60th birthdays of King Bhumibol and Queen Sirikit, these two shrines sit high on the mountain surrounded by manicured terraced gardens. The site costs an extra 100 Baht to enter. Late afternoon visits catch the best light across the panoramic ridges.

Doi Inthanon National Park Visitor Guide

Best Time to Visit

Target November through February for clear skies, morning valley mist, and open hiking trails. Summit temperatures average 10 to 15°C but regularly approach freezing, so pack real winter layers.

Spring poor
March - May

Agricultural burning chokes the air with smoke and haze. Vegetation dries out, and waterfalls slow to a trickle before the rains begin in May. Skip this window.

Summer poor
June - August

Torrential rains turn paths slippery and shut down the Kew Mae Pan trail entirely. Birding remains decent through July, but you'll be dodging frequent heavy washouts.

Autumn good
September - November

September and October deliver the heaviest downpours of the year. By November, the skies clear, temperatures drop, and the main hiking routes reopen for the dry season.

Winter best
December - February

Expect crisp air, morning mist rolling through the valleys, and summit temperatures plunging near or below freezing. Late January brings a brief bloom of pink Siamese sakura.

Hours & Fees

Main park gates open between 5:00 and 5:30 am and close to new entries around 6:00 to 6:30 pm daily. Overnight guests can still move around after hours. The visitor center operates from 8:00 am to 4:00 pm year-round, while most individual waterfalls and viewpoints wrap up access between 4:00 and 5:00 pm. The Kew Mae Pan Nature Trail shuts down entirely from roughly June through October for rainy season forest recovery.

Buy general entry tickets right at the gate. No advance booking is needed for day trips. Bring cash in small denominations. The park lacks ATMs, and ticket booths or food stalls rarely accept cards. The closest reliable cashpoint is in Chom Thong town before you reach the entrance.

How to Get There

The park entrance lies 60 to 70 kilometers from Chiang Mai city center. Renting a vehicle or hiring a driver offers the most practical way to cover the distances between the lower gates and the 2,565-meter summit.

📍 Chom Thong District, Chiang Mai Province

Car or Private Driver

Driving yourself or hiring a driver is the most practical way to explore the park. The route follows paved roads that become sharply winding and mountainous as you approach the summit. You need a vehicle to comfortably cover the 90 kilometers from Chiang Mai city to the peak. Rent a car if you know how to handle steep mountain grades. Otherwise, book a local driver.

⏱ 1.5 to 2 hours to headquarters 💰 800 Baht per day for rentals; from 3,200 Baht for a private driver
Guided Tour

Operators like AK Travel and Take Me Tour run trips out of Chiang Mai. An air-conditioned van picks you up at your hotel and hits the main stops, including the pagodas, waterfalls, and Kew Mae Pan trail. These packages usually cover an English-speaking guide and lunch. It removes the stress of mountain driving. Just prepare for a long eight to ten-hour round trip.

⏱ 8 to 10 hours round trip 💰 From $29 to $66 USD per person
Motorbike

Riding a motorbike up the mountain is for experienced riders only. The initial highway stretch from Chiang Mai moves fast. Inside the park boundaries, the elevation changes drastically and hairpin turns demand solid braking control. Fog often ruins early morning visibility. Skip this entirely if you lack steep mountain driving experience.

⏱ 1.5 to 2 hours 💰 150 to 200 Baht per day, plus fuel
Songthaew (Shared Taxi)

Shared pickup trucks run from Chiang Mai through Chom Thong, proving slow and highly inconvenient. Drivers wait at the station until the back is entirely full. You must make multiple transfers just to reach the park boundaries. Inside, these trucks only pass the lower waterfalls. Reaching the summit requires chartering the whole vehicle.

⏱ 2.5 to 3 hours 💰 250 to 600 Baht round trip

Visitor Tips

Bring Small Baht Bills

There are no ATMs inside the park. The last reliable cashpoint is in Chom Thong town before the entrance. You need cash for the 200 Baht Kew Mae Pan guide fee, the 100 Baht Royal Twin Pagodas ticket, and local food stalls. Card readers are almost nonexistent here.

Pack Winter Layers

Chiang Mai might be sweltering, but the 2,565-meter summit averages 10-15°C year-round. Temperatures drop below freezing between November and February, hitting minus 0.4°C in early 2026. Bring a jacket, hat, and gloves for early mornings. You also need covered shoulders and knees for the Royal Twin Pagodas.

Arrive Early For Trails

The 3-kilometer Kew Mae Pan ridge trail is only open from November to May. You cannot hike it alone. A local Hmong guide is mandatory and costs 200 Baht per group. Guides are assigned first-come, first-served at the Km 42 trailhead, so get there early to avoid waiting.

Leave Plastics And Drones

Thai national parks ban all single-use plastics, including thin bags, straws, and styrofoam containers. Drones are also strictly prohibited without prior written permission from the Department of National Parks. Breaking either rule carries a fine of up to 100,000 Baht. Pack a reusable water bottle instead.

Avoid Holiday Traffic Jams

Visit on a weekday if possible. The winding mountain road gets severely congested during Thai public holidays like Songkran and New Year. On January 1, 2026, over 3,300 vehicles crammed into the park. If you drive yourself, leave Chiang Mai no later than 7 am to beat the rush.

Call To Book Accommodation

Staying near headquarters lets you catch the summit sunrise without a pre-dawn drive from Chiang Mai. You can rent a park bungalow for 1,000 to 6,500 Baht or camp from October to February. The official online reservation system broke down in 2026. You have to book directly by phone.

Nearby Attractions

Mae Ya Waterfall

30-40 minutes' drive from park headquarters

Water cascades over wide limestone terraces into natural pools at this tall, multi-tiered waterfall. It sits just outside the main attraction cluster. You'll need to walk a short distance from the parking area.

6 km east of park headquarters

This traditional Karen hill tribe settlement grows organic coffee and farms terraced rice paddies. The fields turn vivid green late in the rainy season. Stop here for a village cafe break or an overnight homestay.

Chom Thong District town and Wat Phra That Si Chom Thong

30-45 minutes' drive from the park entrance

Hit this historic town for cash, food, and supplies before entering the park. Wat Phra That Si Chom Thong anchors the area, housing revered Buddhist relics.

"I rented a scooter in Chiang Mai and drove the 70 km up. The winding roads are pretty gnarly near the summit. I paid the 300 Baht entry and hired a Hmong guide for 200 Baht to hike Kew Mae Pan. The sea of mist off the ridge was worth the freezing morning temps."

"Caught the wild Himalayan cherry blossom bloom in late January. The pink trees against the pine forest look wild. Later I stopped by Mae Klang Luang village about 6 km from headquarters. Grabbed some local organic coffee from the Karen villagers. Don't forget cash since there are no ATMs inside the park boundaries."

"Took the kids here in early February. We skipped the long trails and stuck to Wachirathan Waterfall. It's right off the main road and easy for young ones to reach. You can't swim because of the slippery rocks, but the spray creates massive rainbows. Paid 150 Baht for the kids' entry."

"We booked a private driver for 3,200 Baht to avoid the mountain traffic. The Royal Twin Pagodas cost an extra 100 Baht each. They enforce a dress code there, so bring pants. We walked the Ang Ka Luang boardwalk through the cloud forest afterward. It's much colder up at 2,565 meters than in the city."

"Left Chiang Mai at 7 am to beat the tour vans. The summit marker is just a short walk from the parking lot. I packed a drone but left it in the car. They'll fine you up to 100,000 Baht for flying without a permit. The 10-degree weather up top was a shock after the lowlands."

"We visited in August during the rainy season. The main Kew Mae Pan trail was closed for forest recovery. We still saw Mae Ya Waterfall, which had heavy flow over the limestone terraces. The trails were pretty slick. Definitely bring a reusable water bottle because they ban all single-use plastics at the gate."
