You can definitely carry. This is Arizona. Just not in the gift shop because it's a state park.
Why would you need a gun anyway?? No Fear. Wear boots in case of Rattlers though.....
Firearms are allowed in city parks for personal protection. However, you can not hunt or practice shooting here.
There is a ranger but not sure how helpful he can be; other volunteers would likely help.
Probably wont need one and there are camp hosts and rangers that can help u with that Question.
The rule says you may not discharge a firearm in the park. I believe the only place it explicitly says you cannot open carry is in the visitor center.
