Huay Kaew Arboretum (สวนพฤกษศาสตร์ห้วยแก้ว)
Popular forested arboretum adjacent to Chiang Mai University and within walking distance of the Nimman expat neighbourhood. Walking paths wind through botanical collections under good shade canopy. Dogs must be leashed. Early morning is ideal — paths are shaded and cooler than open parks. HAZE SEASON NOTE: During March-April, check Chiang Mai Air Quality Index (AQI) before outdoor exercise — avoid on Red/Purple days.
