Park is open all day. Office opens around 7 am
The park is open all day but the visitor center and other facilities don't open until 7 or 8 a.m. depending on the time of the year.
The park is open 24/7.
I have no idea but I would check the Grand Canyon website!
Get there at least 20 min before the rise. It is very cold so bundle up as best you can.
