💡 Good to know

Cooler, generally drier conditions suit the northern route, but road, air and attraction status remain live checks.
Northern haze can sharply reduce air quality and visibility; check Air4Thai before committing to each road day.
The northern green season brings rain and lush landscapes; reconfirm roads, floods, landslides and attraction access before each day.
