Kew Mae Pan Nature Trail Guide

A short loop along an open ridge near the top of Thailand's highest mountain, open November to May

By Mac Kiley · 5 min read · Updated Oct 28, 2026

Kew Mae Pan is the walk on Doi Inthanon, and the one I'd plan a day on the mountain around. It's a loop of about 2.5 to 3 km near the top of Thailand's highest mountain that starts in mossy cloud forest, comes out onto an open grassy ridge with views across the mountains and down to the twin royal pagodas, and drops back into forest. It opens only from 1 November to 31 May, you can't walk it without a local Hmong guide, and the trailhead sits at km 42 of Route 1009, roughly two hours' drive from Chiang Mai.

Key Facts

It opens 1 November and closes 31 May

The trail shuts from June to October every year so the forest can recover in the rains. It also closes on days of heavy rain inside the season.

A Hmong guide is compulsory

Guides wait at the booth by the parking lot and are hired on the spot, about ฿200 per group of up to about ten. Thai National Parks lists ฿220, so carry a little extra in cash.

The park fee comes first

Foreign adults pay ฿300 and children aged 3 to 14 ฿150 at the park checkpoint, plus ฿30 for a car or ฿20 for a motorbike. The guide fee is on top.

Start between 06:00 and about 15:00

Walks start from 06:00 and the last group sets off around 15:00. The trail closes at 16:00.

Allow two to three hours

The loop is about 2.5 to 3 km with steps and a few steep stretches, but nothing technical.

Dress for the cold

December and January mornings near the top are a few degrees above freezing. Take a warm layer even if Chiang Mai is hot.

Is Kew Mae Pan Worth It?

Yes, if you go on a clear morning in season. I think it gives more view per hour of walking than any other short hike near Chiang Mai, because most of the mountain is a drive between viewpoints and this is the one place you walk out onto an open ridge above the forest.

Whether you'll love it comes down to the sky. Cloud often sits on the top of Doi Inthanon, and in March and April the burning-season smoke hides the views you came for. November to February is when I'd go. If the ridge is in fog, the cloud forest at the start is still beautiful, but the reason to walk this trail is the view.

Park fees from Thai National Parks (in force since June 2022) and our park records. The guide fee is ฿200 on our trail record and most recent trip reports, and ฿220 on Thai National Parks, so bring a little extra.

How Hard Is the Kew Mae Pan Trail?

Easy to moderate. Thai National Parks calls it a clear, well-maintained trail, and most people finish the loop in two to three hours with stops for photos. There are steps and some steep, uneven stretches, and at a little over 2,000 m you'll feel the climbs more than you would lower down, so take it slowly if you're not used to altitude.

Wear shoes with grip, because the forest sections stay damp and mossy. You don't need hiking boots.

Published lengths range from 2.5 km (Thai National Parks) to 2.78 km (local tour operators) and 3.2 km (some trip reports), which comes down to where people start measuring. Plan for about 3 km.

How to Get to Kew Mae Pan

The trailhead is on Route 1009 at km 42, a few hundred meters north of the twin royal pagodas, with roadside parking, a ticket booth for the guides and a few food stalls. From Chiang Mai it's about two hours each way, south to Chom Thong and then up the mountain road.

There's no public transport on the mountain itself. Songthaews run from Chiang Mai to Chom Thong at the foot of the road, but nothing runs between the stops inside the park, so you need a car, a scooter, a private driver or a tour.

If you go with a tour, check it names Kew Mae Pan. Most group days drive between the waterfalls, the summit and the pagodas and skip the walk. A private driver lets you put the trail first, which is how I'd do it.

When to Walk Kew Mae Pan

November to February is the best stretch, cool and dry with the clearest views, and the early mornings often have a sea of cloud below the ridge. March and April are open but hazy from the burning season. May is the last month before the trail shuts on 31 May, and the first rains can arrive by then.

Start early. The ridge is clearest before the cloud builds, and the group tours reach the top of the mountain in the middle of the day. I'd drive straight to the trail for an early start, then do the pagodas and the summit afterward. Weekends, New Year and Songkran are the busiest days on the mountain.

Sunrise at Kew Mae Pan

The viewpoint to aim for at sunrise is beside the car park on the main road, which faces east. The viewpoint out on the trail faces west, so it's the wrong place for sunrise, and the trail itself doesn't open until 06:00 anyway. Thai National Parks rates the roadside spot above the summit, which is too often misty.

Kew Mae Pan or Pha Dok Siew?

Kew Mae Pan is the ridge and the views. Pha Dok Siew, near the park headquarters, is a 2.6 km forest walk past waterfalls to the Karen coffee village of Ban Mae Klang Luang, with a compulsory guide at ฿220 per group and a car back to the start for ฿150. Pha Dok Siew is the one to ask about from June to October, when Kew Mae Pan is shut, though it's muddy in the rains. In season, with time for one walk, I'd pick Kew Mae Pan.

What to Bring

A fleece or jacket, shoes with grip, water and cash for the guide and the park fee, because there are no ATMs on the mountain. Stay on the path with your guide. The ridge grassland and the moss are fragile, which is part of why the trail closes for five months a year.
