Climbing Doi Inthanon Thailand - Natural Form and History

Natural Doi Inthanon Thailand - Natural history

Looking at its geological buildup, Doi Inthanon is a granite batholith. With an elevation of over 2,560m above sea level, Doi Inthanon is considered an ultra prominent peak in the Southeast Asian region. The Inthanon Range is a part of the Thanon Thong Chai Range, which in turn is a part of the Thai highlands’ Shan Hills.

Natural Doi Inthanon Thailand - Climbing history

The conservation of the vast pine forests surrounding the Doi Inthanon Range was officially announced in 1954. This led to the birth of today’s Doi Inthanon National Park, just one of the 14 other national parks of Thailand.

Many tribes have settled in the surrounding villages and the authorities have kept both the needs of tourists as well as the local villagers in mind, in order to create a peaceful coexistence of traditions, culture and modern tourism and development. 

Doi Inthanon has always been a point of convergence between natural beauty and historical significance. Monuments, locally referred to as chedis, dedicated to King Bhumibol and Queen Sirikit’s 60th birthday celebrations sit atop the mountain peak. The Bhumibol Dam together with the power of the Ping River work to provide hydroelectricity to the region. The peaks and numerous rivers combine to create many waterfalls that add to the beauty of this national park (the Mae Yai, Mae Pan, Mae Klang, Pha Khun Na, Wang Khwai, Wachirathan, Sirithan, and Siriphum waterfalls).

The national park is home to over 360 different species of birds, making it the best place for bird watching within the entire Thai nation. The park spans over an area of 482 square km, ranging from a mere 800m elevation all the way to 2,565m above sea level. In addition to the birds, Doi Inthanon also plays host to a wide variety of animal species, flora and fauna. It doesn’t take much luck to spot a few barking deer, porcupines and monkeys scurrying about in their natural habitat!

Despite the cold, Doi Inthanon manages to reel in the crowds, with even as many as over 10,000 eager hikers completing the summit on New Year’s Day.

Climbing Doi Inthanon Thailand - Climbing Experience

Surprisingly, despite its elevation and breathtaking views, Doi Inthanon isn’t going to be one of the harder summits you’ll successfully conquer in your hiking adventures. In fact, for most travelers, beginning the day at 08:00 from their stay in Chiang Mai could mean they’ll be back at the hotel again by early evening after a thorough tour of the national park! So even if you are a beginner still learning to grow a love for adventure and heights all at once, Doi Inthanon could be a great choice for you. Remember, unlike its easier and quicker counterpart, the Kew Mae Pan Nature Trail requires a reasonable level of physical activity. The trail consists of steep steps to climb and descend through thick forests.

Climbing Doi Inthanon Thailand - Trail options

Number of options

Doi Inthanon isn’t a very intimidating hike even for the most amateur hikers. For the most part your set of wheels will be able to take you towards the top, but the few hundred metres to the actual summit point from the parking lot can be hiked by foot.

Time to complete
1 day

This is the harder trail of the two easy options. The journey is about 2.5km long and leads trekkers through a winding path amidst thick forests and can last anywhere from 2-4hours. However, if nature is what enticed you to take this trip in the first place, this is definitely the trail you’ll want to follow. Something that particularly deters visitors from taking this trail is that hiring a Hmong tribesman as your trail guide is compulsory and the fixed rate is 200 baht per group. However, the bonus here is that you get to hear a lot of stories about the mountain and the bio diverse ecosystem around you, from a local. When planning your trip, you’ll have to keep in mind that during the rainy season from June until the 1st of November, this trail is closed down.

Number of days
Day 1

Take a car/bike/songthaew from Chiang Mai to the Doi Inthanon National Park. The almost-2 hour long drive includes 57km along Highway No. 108 towards Chom Thong and then a right turn onto Highway No. 1009, with approximately 30km more to go before you arrive at the entrance of the park. Entrance fee for the park is 300 baht per person.

Whilst slightly tiresome, but completely manageable given the brisk weather conditions, it is advisable that you leave your vehicle behind at the parking lot and head straight to the nearest ranger station to get yourself a map and some detailed information on the park. You’ll need to obtain official permission from the Park Office at km 31.

If you’re looking to stay, there are several accommodation options within the park, ranging from camping tents to bungalows and chalets.


Once you’ve started on this particular trail, the first kilometre will take you through a forest of tall trees, enveloped in layers of moss.

The second kilometre opens up to breathtaking views of rolling hills in the distance, green valleys down below and clear blue skylines, as you trek along the mountain’s ridge.

Finally, the last half kilometre will take trekkers back into the thickness of the forest, lined with waterfalls and clear streams.


You’ll be able to catch a quick glimpse of the two chedis in the distance, during the Kew Mae Pan Nature Trail. With an additional 40 baht entrance fee per person, you can get a closer look of the pagodas. The pagodas provide for great sunset views.

This trail is pretty straightforward and consists of about a 360m boardwalk. Completing this trail should take you no longer than 30minutes and you’ll wind up at an elevation of approximately 2,500 m above sea level. The trail is surrounded by lush forest, creating a very mild and comfortable climate throughout the year. In terms of flora and fauna, you will come across a lot of rhododendrons and moss. You’ll also probably want to stick to long socks in order to avoid possible leech attacks during the wetter seasons.

Climbing Doi Inthanon Thailand - Safety & Accessibility


Generally, this part of Thailand has three major seasons – the hot season runs from March through June, the monsoon from June through October, and cool and dry season from November through February. There is no one best time to climb Inthanon. With the peak’s high altitude, Doi Inthanon boasts a perpetually chilly climate all year round, with temperatures even dropping below freezing during the winter season.

An occasional unseasonal downpour is the only weather challenge that could mar your trip.

Though it will not be uncomfortably hot from March to June, the sun can still be harsh on your skin, so make sure you use sun protection in the form of sunscreen and sunglasses.

Climbing safety

Slippery surfaces:  Unexpected rain can slow your progress and make the trail slippery and treacherous at some points.

Insects:  As is typical with any wilderness, you are likely to encounter a few insects and mosquitos. Make sure to use insect repellent especially if you are planning on an overnight stay in the mountains.

Personal safety

Being a popular destination, it is very unlikely you will ever be completely alone or isolated on this trek so there is little to worry about in terms of personal safety.

Permits, Fees, and Regulations

A permit will not be required if you only plan on taking the Ang Ka Luang Nature Trail. However, if you do want to make the most of your trip and try out the Kew Mae Pan Nature Trail, remember to pay the mandatory guide fee and obtain permission at the Park’s office at km 31.

Emergency contacts

Tourist Police: 1155

Fire & Ambulance: 191

Getting there and away

Chiang Mai International Airport is the nearest airport. Your ride from Chiang Mai to the entrance of the national park should take you close to 2 hours by car. If you haven’t got a car or bike, you can always hail a songthaew from the Chiang Mai streets. A common practice is to negotiate a fee for the day so the driver will take you to Doi Inthanon, wait whilst you explore the park and then bring you back to Chiang Mai.

Money Matters

The entrance fee for the park is 300 baht per head. Hiring a Hmong tribesman as your trail guide on the Kew Mae Pan trail will cost 200 baht per group. On this trail, you’ll have to pay an extra 40 baht per person to get a closer look of the pagodas.
