Pa Kia Highland Agricultural Research Station

Pa Kia Highland Agricultural Research Station sits on Doi Mae Taman above Chiang Dao, run as a working research site rather than a built-for-tourists attraction. It trials temperate-climate crops that do not normally grow in lowland Thailand — pears and persimmons among them — as part of a highland development programme aimed at giving mountain communities in the area legal, cash-earning alternatives to older hillside farming. Visitors are welcome, but this is a research station first: contacting the station roughly 10 days ahead of a visit is the standard advice, rather than turning up unannounced.

What draws most visitors is not the research itself but the setting. On cool-season mornings, a sea of mist settles into the valley below while Doi Luang Chiang Dao’s limestone ridge rises clear on the opposite side — one of the more reliable mist-viewing spots in this part of Chiang Mai province. The station keeps basic guesthouse rooms and a tent-camping area for overnight guests, who bring and cook their own food since there is no restaurant on site. Clear night skies at this elevation make it a reasonable stargazing stop too, and the surrounding forest holds enough bird species to interest anyone who packs binoculars.

Insider Tip: Book your visit and stay well ahead — this is a functioning agricultural station with a small guest capacity, not a resort, and staff plan around confirmed arrivals rather than walk-ins.

Watch out: Facilities are basic by design. There is no on-site food service, so bring your own supplies if staying overnight, and expect cold nights even though you are still in tropical Thailand — winter temperatures at this elevation can drop close to single digits Celsius.

The station is a short drive from Chiang Dao town and its better-known limestone cave system — pack for both cold mountain nights and Chiang Dao’s warmer valley floor if combining the two on one trip.
