What Chedi Luang is one of the must sees when you are staying in Chiang Mai.
Unfortunately the entry to the little blue chamber (the picture with me) is for men only. Neverthless the main temple at Wat Chedi Luang is accessible for men and woman. And there are many nice temples and monuments around Wat Chedi Luang. Another must visit is the Phra Singh temple and only a 13 minutes walk away.
