Route 1009 is the only paved road to the summit of Doi Inthanon, Thailand’s highest peak at 2,565 m, climbing 48 km through tropical, pine and rare montane cloud forest.
Turn off Highway 108 at Chom Thong and climb steadily past the Mae Klang and Wachirathan waterfalls to the Twin Royal Pagodas near the top, then the summit car park. Well-surfaced throughout; at the top the temperature can be 15C cooler than Chiang Mai, with frost on winter mornings.
