Does the campground have wifi

Yes

I have no idea on that. I was enjoying the beauty of the park! Took lots of pictures

Yes it does have wifi...

There may be mobile hot spots around there the Park should have it also It is a great place to go and see, also after you leave there follow the RD and you can get to little river canyon on that's a great place to go for a drive. You can follow the directions all the way to Chattanooga

I think it does

I didn't stay at the camp ground. But they do have a website you should be able to find out there.
