Question: is grand canyon open in december?
Answer: The Grand Canyon is open 365 days a year, though some roads may close due to weather or snow removal. (For example, one of the days I was there, the Hermit's Road was closed because of snow.) Visitor Center winter hours: 9 a.m. to 5 p.m. Park Store winter hours: 8 a.m. to 6 p.m.
