Phra That Doi Koeng Temple

Phra That Doi Koeng Temple sits on a remote forested peak in Doi Tao district, roughly 124km south of Chiang Mai city and about 14km up a rough mountain track from the nearest village road. The white chedi at its summit is said to enshrine a phra nalat — a relic identified as part of the Buddha’s forehead bone — which is what turns this from a scenic hilltop into an active pilgrimage site for people from Doi Tao and beyond, most visibly during the Magha Puja period each January or February, when devotees walk up from the lakeside to pay respects and bathe the relic in a trek that takes roughly 2-3 hours on foot.

The temple’s modern form dates to a restoration led by the wandering monk Kruba Boonsri, who rebuilt the monastic buildings on the site after finding it during his travels through the area. It remains a modest, working temple rather than a tourist complex — there’s a chedi, a small viharn, and monks’ quarters, with panoramic views over the forested ridges and, on a clear day, glimpses of the Doi Tao reservoir below.

Watch out: The access road is the real story here. From Ban Huai Hin Dam in Na Kho Rua subdistrict, the last 14km run over a mix of rock, sand, and patchy concrete, climbing steep switchbacks with narrow stretches and no barriers. A pickup truck or 4WD is strongly recommended over a sedan or a scooter not built for off-road conditions, and the drive up alone takes 30-45 minutes even in good weather.

Insider Tip: If you’re not up for the drive, the Magha Puja pilgrimage walk (January-February) is the more traditional way in — locals set off from the Doi Tao Lake side and the 2-3 hour climb is treated as part of the merit-making, not just a means of getting there.

Free to enter, with no fixed opening hours — this is an active temple on a public hill rather than a gated site, so plan around daylight and driving conditions rather than a ticket window. Dress modestly (covered shoulders and knees) and remove shoes before entering the viharn, as at any Thai temple.

The wider Doi Tao area of Hot district also holds Ob Luang National Park and its Mae Chaem River gorge — both make sense to combine with a Doi Koeng visit if you’re already driving this corner of southern Chiang Mai province.
