Near the summit of Doi Inthanon — Thailand's highest mountain at 2,565 metres — two magnificent royal twin chedis crown a forested ridgeline. Built in 1987 and 1992 to honour King Bhumibol and Queen Sirikit on their respective 60th birthdays, the chedis are named Naphamethanidon and Naphaphonphumisiri. They are architecturally stunning: white and terracotta-toned structures set in manicured gardens, with interior murals depicting Buddhist cosmology and scenes from Thai history.
The surrounding Doi Inthanon National Park provides the context — at this elevation, the forest transitions to temperate zone with mosses, ferns, and rhododendrons replacing lowland jungle. Temperatures can drop to single digits on winter mornings (November–February), a jarring contrast to the Bangkok heat most visitors left behind.
The twin chedi complex is the main draw for most visitors, but the national park also contains the highest waterfall in Thailand (Wachirathan Falls), numerous hiking trails, and excellent birdwatching. The summit itself has a small shrine to Chao Inthanon, the last prince of Chiang Mai, whose ashes are interred there.

How to Get There
Doi Inthanon is 80 km southwest of Chiang Mai city. Most visitors join a day tour from Chiang Mai (550–900 THB) or rent a motorbike/car. No direct public transport to the peak. The drive from Chom Thong town takes about 1 hour on a winding mountain road.
Visitor Tips
Bring a jacket or sweater — even in hot season, the summit area can be 10–15°C cooler than Chiang Mai city.
Combine with Wachirathan Waterfall (35 km from peak) and the nature trails in a full-day visit.
The 30 THB entry to the chedi compound interior is worth it for the murals alone.
Early morning (7–9 am) often brings mist and atmosphere to the gardens.
The road to the summit is paved but steep — motorbikes should be in good mechanical condition.
