Chiang Mai is one of Thailand's safest cities for visitors. The main health concern is seasonal air pollution (Feb–April) and trekking accidents in remote hill-tribe areas.
Save these numbers before you arrive. Calls are free from most local phones.
Read before you go — these are the situations most likely to affect your safety.
Monitor PM2.5 between February and April; wear an N95 mask outdoors and keep windows closed on bad days.
Use licensed trekking guides and tell someone your route before departing.
Drive defensively on mountain roads to Doi Suthep — fog and bends are hazardous at night.
Drink bottled or filtered water; tap water is not potable.
Recognise the pattern, decline firmly, and walk away.
Some hill-tribe villages charge entrance and photo fees that may not support the community. Use ethical, reviewed tour operators.
Brand-name items at the Night Bazaar are almost always fake. Inspect quality and haggle — there are no refunds.
Fix the fare before getting in; meters are rare. Short hops inside the old city are walkable.
