What should I know before visiting Chiang Mai?

Direct answer

Chiang Mai is a culturally rich, relaxed northern Thai city with temples, markets, mountain excursions, and a distinct Lanna heritage—plan for warm weather, some air quality variation in dry season, and respect for local customs.

Visa / entry requirements

  • Check Thailand visa rules for your nationality; many countries get visa-exemption or visa on arrival (typically 30 days for tourists).
  • Passport should be valid for at least 6 months from entry and may require a blank page.
  • For longer stays (work, study, or over 30/60 days), apply for the appropriate visa before travel or extend at an immigration office.
  • Carry a printed return ticket and proof of accommodation when requested.

Best time to visit

  • Cool/dry season (November–February): most pleasant—cooler nights, blue skies. Peak tourist season.
  • Hot season (March–May): very warm; outdoor activities can be tiring mid-day.
  • Rainy season (June–October): fewer crowds, lush landscapes, occasional heavy rain; some rural trails slippery.
  • Burning season (late February–April, variable): agricultural burning causes haze and poor air quality—check AQI and consider masking or postponing hikes if AQI is unhealthy.

Safety tips

  • General: Chiang Mai is relatively safe; use normal urban precautions (watch belongings, avoid poorly lit areas at night).
  • Scams: be wary of tuk‑tuk or taxi offers claiming a site is closed and suggesting expensive alternatives; insist on meter fares or use Grab when available.
  • Motorbike: helmets are required; riding a motorbike involves risk—only ride if experienced and insured. Check local road conditions and drive defensively.
  • Health: bring insect repellent (mosquitoes), sunscreen, and a small first‑aid kit. Drink bottled water if unsure about sources.

Local customs and etiquette

  • Respect the monarchy and Buddhist practices—avoid political commentary and never disrespect royal images.
  • Remove shoes before entering homes and many temples and shops; dress modestly at temples (shoulders and knees covered). Some temples lend/require coverings.
  • Wai (palms together) is a respectful greeting; follow locals’ lead.
  • Public displays of anger or loud confrontation are frowned upon—stay calm and polite.

Currency and money

  • Thai baht (THB). Cash is widely used—carry small bills for markets and temples.
  • ATMs are common in Chiang Mai; inform your bank of travel. Check fees for international withdrawals.
  • Credit cards accepted at many hotels, restaurants, and larger shops, but not at small stalls and some taxis.

Transportation

  • Getting there: Chiang Mai has an international airport (CNX) with domestic and regional flights. Overnight trains/buses connect from Bangkok.
  • Around the city: Grab (ride-hailing) and metered taxis operate; tuk‑tuks and songthaews (red trucks) are convenient for short trips—agree price beforehand for non-metered rides.
  • Renting scooters: common and convenient but risky—inspect the vehicle, take photos, get insurance if possible, and always wear a helmet.
  • Day trips: many travelers hire private drivers, join group tours, or rent a car for nearby attractions (Doi Suthep, Pai, Chiang Rai, elephant sanctuaries).

Must-know tips & local insights

  • Temples: visit Wat Phra That Doi Suthep early to avoid crowds and enjoy cooler air; Wat Chedi Luang and Wat Phra Singh are central highlights.
  • Night markets: Chiang Mai Night Bazaar, Saturday (Wua Lai) and Sunday Walking Streets are great for food, crafts, and souvenirs—bargain politely.
  • Food: try khao soi (northern curry noodle), sai ua (northern sausage), and fresh fruit from markets. Street food is generally safe—choose busy stalls.
  • Ethical tourism: choose accredited elephant sanctuaries (no riding) and support community-based tours.
  • Festivals: Loy Krathong/Yi Peng (Nov) is spectacular—book accommodation early; Songkran (mid-April) is Thailand’s water festival—expect citywide celebrations.
  • Accommodation: Old City is central for temples and markets; Nimmanhaemin is trendier with cafes and nightlife; pick based on your interests.
  • Connectivity: SIM cards (prepaid) are cheap and available at the airport for good data coverage.

Quick checklist

  • Passport, visa (if needed), travel insurance
  • Local currency and cards; notify bank
  • Lightweight clothing + a modest outfit for temples
  • Sunscreen, insect repellent, basic meds
  • Helmet if renting motorcycle, and copies of reservations/tickets
  • Check AQI and weather before outdoor plans

Enjoy Chiang Mai—respect local culture, plan around seasonal haze, sample northern cuisine, and take time to explore both city charms and nearby nature.
