Turn off Hwy 74 between Apache Junction and Florence, Turn East on Cottonwood Canyon Rd. and there is dispersed camping with ZERO amenities starting in about 2 thru 5 miles on both sides of the road.
This is a very popular off road spot for Motocross motorcycles, Jeeps, ATV's, and Side by Sides so be prepared for some dust and some noise from vehicles. There are lots of trails to ride.
This is Arizona State Trust Land so a permit is required but can be purchased and downloaded from their website at a cost of $21.00 and it is valid for 1 year for the family pass.
The location was clean and well cared for buy the people that camp there, and there are rock rings for fires but you will need to bring your own wood to burn as there is little in the desert and nowhere close to purchase any.
We stayed with a group in November and the weather and the sunrise and the sunsets were absolutely amazing to behold. We will definitely be back both for the wide open spaces and the great places to ride.
I spent 4 days here in October of 2018. It is a nice and quite place with dispersed camping right on Apache lake. There are multiple camping spots with fire-pits in the shade or you can pull right down near the water and walk out your front door right on a gravely beach and into the water.
While I was here I did encounter other campers both in tents and in RV's, the road in is about 10 miles of washboard dirt road from the Roosevelt Dam side but it is still passable in a motor home or any other high clearance vehicle. Some people just come for the day and still others seem to stay a few nights, but over all there is lots of room and no-one has to camp close to one another if they don't want to.
There is also a non-paved boat ramp marked out on the beach and being that the beach was more gravel than sand I never saw anyone get stuck or even spin a tire while either launching a boat or pulling one out.
There are also 3 port-a-potties located on a trailer and a dumpster there to throw away your trash, but unfortunately people always seem to leave some trash laying around. for that reason and that only I rate it a 4 out of 5.
