Question: is ayutthaya open on sunday?
Answer: 2. Re: Is the Ayutthaya Park open on Sundays? The ruins are open every day of the year during daylight hours. The active temples are similarly open every day of the year, but it's generally considered politest to visit in the morning, say from 8 a.m. to 11:30 a.m., and late afternoon, say 3:30 p.m. to 5:30 p.m..
