Piang Luang to Arunothai (Route 1778)

Our rating:

The recent completion of Highway 1778 linking Piang Luang up with Muang Na and Arunothai now means an awesome loop is on offer, though while the route south from Wiang Haeng to Pai is not yet sealed, it is currently a well-maintained 55-kilometre dirt track.

Kae Noi has grocery stores, noodles and petrol while towards the eastern end of the village is a fine little coffee shop Love Kae Noi.

From Kae Noi the route rises again with the hills of Pha Daeng National Park to the south and the Burmese border to the north until a very steep descent leads you down to Muang Na, another of those now sleepy, remote, former KMT/Shan settlements whose mere name in previous times would have sent shivers down the spine of a Thai border patrol trooper.
