Chiang Mai is considered a digital nomad hub and is exceptionally safe regarding crime. The walled Old City is heavily monitored, relaxed, and welcoming. The greatest health risk here is environmental: from late February to April, the region experiences the 'burning season' (agricultural crop burning), creating some of the most hazardous, toxic air pollution (PM2.5) in the world. Tourists should avoid visiting during this time or wear high-quality N95 masks. If renting a scooter to drive the famous Mae Hong Son loop or visit Doi Suthep, ensure your brakes are reliable and you are highly comfortable with steep, winding mountain roads.
