They have campgrounds there.
Plenty of spots just past the lake on the north side of the road have a great timeI am thinking about taking the kids to Lake Mary and wondered if anyone knew of afew camping spots near by. I have never been up there.
There is also a road to get to the other side but i wouldnt recommend trying that... Definately dont do it without a really good GPSpeople have camped on the other side of the lake, they used a boat to get there. it was almost directly across from the boatramp.
IN AZ you can camp anywere as long as its not posted, you dont need a camping site persay to camp.
