While Thailand is famed for beaches and temples, its northern and western highlands harbor impressive mountains, all part of the Shan Hills and Tenasserim Hills systems. Here are the six highest summits:
| Rank | Mountain | Elevation | Province | Key Features |
|---|---|---|---|---|
| 1 | Doi Inthanon | 2,565 m (8,415 ft) | Chiang Mai | Highest point in Thailand; part of Doi Inthanon National Park; cloud forests, waterfalls, hill tribe villages; summit accessible by road. |
| 2 | Doi Pha Hom Pok | 2,285 m (7,497 ft) | Chiang Mai (formerly listed as Phetchabun – correction: it's in Chiang Mai near Myanmar border) | Second highest; part of the Daen Lao Range; fern forests, rare birds, border ridge trail. |
| 3 | Doi Chiang Dao | 2,175 m (7,136 ft) | Chiang Mai | Limestone massif; famous cave system (Chiang Dao Cave); sheer cliffs; biodiversity hotspot. |
| 4 | Doi Phu Kha | 2,079 m (6,821 ft) | Nan | Highest in Nan Province; Doi Phu Kha National Park; rare Bretschneidera sinensis trees; misty ridges. |
| 5 | Doi Mae Yao | 2,028 m (6,654 ft) | Chiang Mai (correction: actually in Chiang Mai, not Phetchabun) | Part of the Khun Tan Range; less visited; montane forest; scenic viewpoints. |
| 6 | Doi Pha Chang | 1,980 m (6,496 ft) | Nan | Near Doi Phu Kha; rugged terrain; part of the Luang Prabang Range extension. |
These peaks are primarily composed of Paleozoic limestone, granite, and metamorphic rocks uplifted by the Himalayan orogeny's far-field effects. They host unique montane ecosystems—rhododendron thickets, sphagnum bogs, and endemic species—and are critical watersheds for the Chao Phraya, Mekong, and Salween river systems.
