A damp morning air greets hikers as minivans thread out of Chiang Mai and up a road that climbs toward cool cloud and pine. By midmorning the group reaches the summit ridge at 2,565 meters—thin, brisk air; the Ang Ka mossy trail breathes beneath a canopy of old trees—and the trek begins at Pha Dok Siew, a rainforest valley where vines and bamboo frame narrow footpaths.

When visiting Ban Mae Klang Luang, ask before photographing villagers and accept locally prepared food as a cultural exchange.
