Doi Inthanon Travel Guide
Doi Inthanon is the highest peak in Thailand at 2,565 metres and the centrepiece of a large national park southwest of Chiang Mai. It offers cool mountain air, cloud forest, waterfalls, the famous Twin Royal Pagodas, and the chance (in winter) to see frost — a rare sight in tropical Thailand. Most visitors come on a day trip from Chiang Mai, and with an early start you can cover the main highlights comfortably. If you enjoy nature, cooler temperatures and mountain scenery, this is one of the strongest reasons to leave the city.
How to Get There
From Chiang Mai
The summit is roughly 90–100 km from the city (1.5–2 hours by car). The usual route is Highway 108 south to Chom Thong, then Highway 1009 up the mountain.
Transport options
Most people join a organised day tour or hire a private car/driver. Independent travellers can take a songthaew to Chom Thong and then charter another vehicle up the mountain, though this is slower and less convenient. There is no direct public bus to the summit.
The road is paved but winding. Start early if you want to avoid afternoon cloud and have time for the main stops.
Climate & Best Time to Visit
Temperatures drop noticeably with altitude. The summit is often 15–20°C cooler than Chiang Mai.
Best time: November to February
Cool, clear and the most popular period. This is when you have the best chance of seeing frost in the early morning and the classic “sea of mist” views. Bring a warm jacket — it can feel genuinely cold at the top.
March to May
Still good for hiking (Kew Mae Pan remains open until the end of May), but warmer and sometimes hazy.
Rainy season: June to October
Lush and green with fewer visitors, but the Kew Mae Pan trail is closed and cloud cover is more frequent. Waterfalls are at their strongest.
What You’ll Love Doing Here
Most day-trip itineraries follow a logical sequence up the mountain. Near the top you will find the summit marker at 2,565 m and the short Ang Ka Luang Nature Trail — an easy boardwalk through mossy cloud forest that feels completely different from the lowlands.
Just below the summit are the Twin Royal Pagodas, built in honour of the late King Bhumibol and Queen Sirikit. The gardens around them are well kept and the views on a clear day are excellent.
The standout hike is the Kew Mae Pan Nature Trail (open roughly November to May). It is a guided 3 km loop along a ridge with panoramic views. A local guide is mandatory and arranged at the trailhead. On a clear morning it is one of the best short walks in Thailand.
Lower down the mountain you will find several waterfalls, including the popular Wachirathan Falls, and Hmong and Karen villages where you can stop for coffee or lunch. The Royal Agricultural Station is another common stop for gardens and local produce.
Most visitors treat Doi Inthanon as a full day trip and return to Chiang Mai in the late afternoon.
