💡 Good to know

Cooler, generally drier conditions suit the loop, but every mountain road and park remains a live check.
Northern haze can sharply reduce air quality and visibility; check Air4Thai before committing to each mountain leg.
The northern green season brings rain and lush landscapes; reconfirm roads, landslides, floods and national-park access before each day.
