Doi Inthanon in One Day: What the Tour Shows You, and What It Costs on Top

Doi Inthanon is the highest point in Thailand at 2,565 metres, and the day trip to it is the most-booked single excursion in Chiang Mai after the elephants and the Chiang Rai day. Our inventory holds 206 mountain and waterfall offers for this city, from €10.30, with 61,051 reviews between them.

The trip is worth doing. But two things about it catch people out: the mountain is not warm, and the price you paid is usually not the price you pay.

The fees that come on top

This is the single most useful thing to know before you book. The most-booked option, the Doi Inthanon National Park Eco-Friendly Tour – €33.57, 4.6 stars, 7,318 reviews, 9 hours – lists the park entrance fee as not included, and states the amounts on its own booking page: 300 THB for an adult, 150 THB for a child. The twin pagodas are a second, separate ticket at 100 THB per person. Both can be added to the booking as an option instead.

So a couple booking the base price is looking at another 800 THB at the gate unless they tick the boxes. That is not a hidden charge – it is written down – but it is written down in the part of the page nobody reads.

The Doi Inthanon Park with Kew Mae Pan Hike day trip – €37.54, 4.7 stars, 1,023 reviews, 11 hours – handles it differently and more clearly: an economy package where you pay 400 THB in cash on the day, and a full package where the fees are already in. Pick-up runs 7:00 to 7:30 am and you are back between 5:30 and 6 pm.

Kew Mae Pan is shut for five months of the year

The best-known walk on the mountain is a ridge loop of two and a half to just over three kilometres – sources measure differently – with a long open stretch above the tree line. Two things govern it.

It is open from 1 November to 31 May and closed from June through October so the forest can recover. If you are in Chiang Mai in July, this trail is not an option, and a tour title that mentions it should be read carefully. The listing above states the season plainly – only from November to May – which is the right way to sell it.

And you cannot walk it alone: a local guide is mandatory and is hired at the trailhead itself, not booked in advance. Most sources put the fee at 200 THB per group of up to ten people – not per person; a few say 220 THB. Carry it in cash and confirm at the trailhead.

The same applies to the Pha Dok Siew trail on the other side of the park, which runs down past rice terraces to the village of Mae Klang Luang and also requires a guide. Several tours are built around it – the Doi Inthanon Trip with Pha Dok Siew Guided Trek at €27.23, 4.6 stars, 1,292 reviews, is the cheapest. Its own description makes a point worth repeating: the terraces are green in the rainy season, June to September. The months that close Kew Mae Pan are the months that make Pha Dok Siew look its best.

The guide fee here is quoted between 50 and 220 THB per group depending on the source. Again: carry cash, ask on site.

What a standard day actually contains

Four stops, in this order or close to it: the summit marker and the Ang Ka Luang boardwalk beside it, the twin pagodas, Wachirathan waterfall, and usually a Hmong village or a coffee farm.

Ang Ka Luang is worth setting expectations on. It is a raised walkway through mossy cloud forest, and the operator describes it honestly as a short 360-metre boardwalk and not a full hiking trail. It takes about half an hour at a slow pace. Sources disagree on both its exact length and whether it is genuinely step-free, so if that matters to you, ask before booking rather than after arriving.

The two pagodas – Naphamethinidon and Naphaphonphumisiri – were built for the sixtieth birthdays of the King in 1987 and the Queen in 1992, and stand about five kilometres below the summit with the terraced gardens you have seen in every photograph of this mountain.

Mae Ya, the tallest waterfall in the park, sits in the southern section behind its own checkpoint roughly 17 km from the main gate. It is not on the standard day route, and none of the nine tours we checked includes it. If you have seen a photo of Mae Ya and booked a Doi Inthanon day expecting it, that is the mismatch. It is not out of reach, though: a few offers in the inventory do go there deliberately, mostly as private tours or paired with the Pha Dok Siew trail – you just have to look for it rather than book the standard day.

Cold, and then smoke

The summit stands a good two thousand metres above a city that itself sits at around 300. In the cool months the difference is dramatic: in January 2026 the Bangkok Post reported frost returning to Doi Inthanon at the season’s lowest temperature, on mornings when Chiang Mai itself was a mild 15 degrees. People arrive in shorts. Bring a fleece or buy one from the stalls at the top.

The other seasonal problem runs the opposite way. Northern Thailand’s burning season runs roughly from February into April, peaking in March, and on bad days the view from the ridge is haze rather than mountains. Nobody publishes a visibility figure, so the honest version is: in March you are booking the walk, not the panorama.

Several operators also list medical exclusions for the high-altitude tours – high blood pressure, heart conditions, previous altitude sickness, and in one case travellers over 70. Those are the operators’ own conditions, not medical advice from us. If any of them might apply to you, that is a conversation with your doctor before the trip and with the operator before you book.

If you drive yourself

It is roughly a two to two-and-a-half hour drive to the summit, on Highway 108 to Chom Thong and then the climb on the 1009. Sources give the distance as anything from 70 to 100 km, mostly because they measure to different points – the park gate is a long way below the peak.

Driving yourself changes three practical things: you pay the park fee in cash at the gate rather than through a booking, you hire the Kew Mae Pan guide on arrival as a walk-in, and you set your own hours instead of leaving town at seven. The road is paved and steep with long curves. Thailand drives on the left, and an International Driving Permit carried alongside your own licence is what police checks expect.

If that sounds like the better day, it is worth comparing car hire for Chiang Mai before you commit – for two or more people the guided day is often still cheaper once the fees are in, and that is a calculation you can only do with both numbers in front of you.

For the rest of the mountain, including the shorter waterfall half-days that do not involve the summit at all, the Doi Inthanon and waterfall tours page has the current inventory. Camps and mountains often share a morning: several operators combine Doi Inthanon with an elephant camp, and one of those is covered in our guide to reading an elephant camp listing.
