Hi Thank you for visit my beloved hometown Chiang Mai , i would like to give some suggestion for another Koreans or travelers who interest to come to Chiang Mai. Read below vvvvvvv The best time for coming here would be around 1.May - October it's a low season because it's during rainy season of year, the weather will not too hot and less of people here and also good for travel to natural tourist attraction . 2. October - February HIgh season because it's winter season the weather also not too hot and chill less than 20c in the night time. i would not suggest to come here in summer March - April because the weather quite bad from wildfire and the weather is very hot. Transpotion in Chiang Mai : you should avoid to call for red truck taxi or tuk tuk because they don't have a standard for service and cost so you should call for Grab taxi or others taxi's application. rent a bike or car is good choice also for travel in Chiang Mai because we still have a lot of tourist attraction outside the oldtown .
