What to Do in Chiang Mai in September

Recommendation Rate of Travel: 
In the early morning, it is advised to attend the alms giving, a traditional Buddhism ritual existing for centuries there. Locals give food and other living necessities to monks to make merits. The best sites to give alms include Chiang Mai Gate Market, Somphet Market and Kruba Sriwichai statue. Coming to Chiang Mai, you should also visit at least one of the various temples. Wat Buppharam just outside the old town is a unique one combining Lanna-Thai and Burmese architecture style. Although not big, it is fully equipped, luxury and delicate to every detail. On a sunny day, it’s recommended to make a trip to the surrounding primitive forests to experience the thrilling zip line.
