Pai Canyon

Pai Canyon is an eroded ridge-and-gully formation near the town of Pai in Mae Hong Son province in northern Thailand. It is noted for narrow, red-earth ridgelines and exposed cliff edges that create dramatic, walkable viewpoints.

A compact network of trails links several lookout points along the canyon ridges; many visitors walk short sections of the ridgelines to photograph the cliffs and the surrounding Pai valley. Trails are informal and can be narrow in places, which is why many visitors come specifically at sunrise or sunset for the light and views.

The canyon formed through long-term erosion of local soils and sedimentary deposits rather than by large-scale construction. Its appearance and pathways have been shaped by seasonal rains and ongoing erosion.

Pai Canyon sits a short drive from Pai town in Mae Hong Son province, set on the higher ground overlooking the Pai valley. The site is accessed by local roads from the town center.

• Best time to visit: Sunrise and sunset are the most popular times for visitors due to the light on the red soil and broad valley views, and these periods are busiest.
• Safety: Trails are narrow and include exposed drop-offs; caution and sensible footwear are advised when walking the ridges, particularly after rain when paths can be slippery.
