Entities
Chiang Mai
Northern Thailand's strongest food-and-culture base when air quality is acceptable.
Current planning state
This page keeps identity, related pages, source notes, and practical checks together for this place or transport node.
Temples, markets, cafes, and northern-food depth give Chiang Mai a strong indoor and low-speed backup pattern.
Roads, rain, and smoke can make mountain-edge add-ons like Pai or viewpoints a worse fit than the city itself.
