Chiang Mai

November–January is unmatched: relatively cool, clear air (26-28°C by day, 12-13°C evenings). December-January is busiest and priciest (Christmas/New Year), so book ahead if you pick those. Avoid February–April if you can — agricultural "burning season" blankets the city in thick haze, sometimes ranking Chiang Mai among the world's most polluted cities, peaking in March.

• Wat Phra That Doi Suthep: the golden mountaintop temple with a panoramic city view — go at sunrise to dodge crowds and heat
• The Old City's big three temples: Wat Chedi Luang, Wat Phra Singh, and Wat Chiang Man, all within walking distance of each other
• Sunday Walking Street on Tha Phae Road — Chiang Mai's largest and most atmospheric craft-and-street-food market
• An ethical, no-riding elephant sanctuary — feeding and bathing elephants in a natural setting, no chains or riding shows
• Doi Inthanon National Park: Thailand's highest peak and gorgeous waterfalls, a full-day trip from the city
• A Thai cooking class — a family-friendly activity starting with a local market tour, ending with a meal you made
• Chiang Mai Night Safari: a night zoo with a tram ride, a family favorite
• Wua Lai Saturday Night Market — a calmer, less crowded alternative to Sunday's market with the same craft-market feel

Families: Nimman — a modern district with spacious family rooms near Maya Mall (cinema, arcade) — or the Old City itself for walking straight to temples and markets. Couples: Nimman for its stylish cafés, or a boutique riverside hotel on the Ping River for a quieter mood. Budget: guesthouses in the Old City or Santitham district — very reasonable rates, central location.

Watch out for "burning season" (February–April, peaking in March) when the air turns to thick haze that bothers even healthy people — check the air quality index before traveling those months and carry an N95 mask if you'll be out long. Never ride an elephant no matter how tempting or cheap the offer looks; choose only sanctuaries built around feeding and bathing, with no riding or chains. Agree on a tuk-tuk price before getting in, or just use Grab — and ignore any driver who suggests a "quick stop" at a gem or silk shop, which usually means a guaranteed commission for him, not a real deal for you. Rental scooters are everywhere and look like a quick fix for getting around, but tourist accidents on them are common — think twice before renting, especially with family, and make sure you hold a valid international driving permit if you do.

3-4 days

Suggested plan:

1. Day 1: Arrive and settle in, then walk the Old City temples (Chedi Luang, Phra Singh, Chiang Man), capping the day at an evening market if timing lines up
2. Day 2: Sunrise climb to Doi Suthep for the view and quiet, then an afternoon in Nimman for cafés and shopping
3. Day 3: Full-day trip to an ethical no-riding elephant sanctuary, with a Thai cooking class in the evening
4. Day 4: Day trip to Doi Inthanon for waterfalls and the summit, or a Night Safari evening before departure
