Local notes for Chiang Mai

The burning season is the single most important thing to know about visiting Chiang Mai and almost no brochure mentions it. From roughly mid-January to mid-April, agricultural stubble burning and forest fires fill the valley — the city sits in a mountain basin that traps the smoke — and Chiang Mai has repeatedly been ranked the most polluted city in the world during March, with PM2.5 readings several times the level considered hazardous. It coincides exactly with the dry, cool weather visitors are told to come for. If you have asthma or a heart condition, or are travelling with small children, come between November and January instead, and check IQAir or the Thai PCD readings before you book late-season flights.

Doi Suthep is a mountain road, and the way people get hurt on it is by renting a scooter to do it. It is 15 km of continuous hairpins with heavy traffic and no shoulder, and the songthaews that do the run all day cost very little. If you have never ridden a motorbike, this is not the road to learn on — and Thailand's road-death statistics are in the country safety guide for a reason.

Choose an elephant camp on what it does rather than what it is called. 'Sanctuary' is not a protected word here and the range runs from genuine rescue to riding camps that renamed themselves. The things worth checking: no riding at all, no bullhooks, no performances or painting, small groups, and elephants that can move away from visitors. Bathing with elephants sounds gentle and is increasingly criticised by welfare organisations because it means the animals are handled all day. If a camp will not answer these questions by email before you book, that is the answer.

The waterfalls people are sent to are slippery in specific ways. Bua Thong is climbable because the limestone is grippy rather than mossy, which genuinely works — but the streambeds around it are not, and the same rock is treacherous when a section is wet with algae. Follow the roped routes, go barefoot as everybody does, and do not climb after heavy rain.

Two dry, boring facts that catch people out: Doi Inthanon is a national park with a foreigner ticket several times the Thai price, so budget for it, and the summit at 2,565 m is genuinely cold — single figures at dawn in December, when the city below is at 25 °C.

Staying safe in Chiang Mai

The honest opening: Chiang Mai is a straightforward city to visit, and the safety work is ordinary - good habits around belongings, transport and the weather, with a plan for the unlikely.

The setting in one line: The capital of the Lanna kingdom for five centuries before it was ever part of Thailand, and it still does not feel like the rest of the country

🚨 In an emergency

The numbers to save in Thailand: 191 for general emergencies, 1669 for an ambulance, and the multilingual 1155 tourist helpline for anything from lost documents to disputes.

Travel insurance arranged before arrival is the quiet backstop for everything on this page - the medical care, the replaced phone, the missed connection - and it costs less than any single one of those events.

🌙 Out at night

Night walking works in Chiang Mai the way it works across the region: stick to the streets that still have people on them, and most of the safety question answers itself.

Keep the ride home decided before the last hour - a saved pickup point, a known route back, a phone that is not on its last percent - and the evening ends the way it started.

👜 Belongings

For visitors almost everywhere, the realistic loss is a belonging, not a person - so: bags zipped and carried in front in crowds, queues and on transport; the phone off the café table; and the passport in the hotel safe with a copy carried instead.

Never carry everything at once: the day's card and cash in the bag, the backups in the room - a habit that caps any bad moment at an inconvenience.

Market discipline in Thailand: bag across the body, phone in the front pocket, and everything else out of reach of the crowd that presses past.

🚕 Transport and roads

The Thai road rules that matter: cross with the locals, and never ride two wheels without a helmet - it is the single most consequential safety decision available here.

🌡️ Weather and the elements

The plains summer is the one element that needs respect: start the sightseeing early, keep the midday plans indoors or shaded, and carry water as a habit rather than a response.

🏥 Health basics

Two rules carry most of the health question: drink sealed or filtered water, and eat where the queue is - a busy stall is a self-auditing kitchen.

Carry the small pharmacy that saves a morning: rehydration sachets, anything you take regularly in original packaging, and a basic first-aid kit - and let a real pharmacy handle anything larger; both countries have excellent, inexpensive ones.

✅ The one-minute checklist

Save 191 / 1669 ambulance / 1155 tourist helpline
On two wheels: always a helmet
Belongings: zipped bag in front, phone off tables, passport in the safe
Split cards and cash - the day's spending only in the day bag
Water: sealed bottles only; food: busy stalls
Kit: rehydration salts + medicines in original packaging
Insurance arranged before arrival - the quiet backstop to all of it
