Mesquite Wash is located approximately 20 miles northeast of Fountain Hills, Arizona. Follow the Bee Line Highway, SR 87, a few miles past the Four Peaks turn off. Watch for the Mesquite Wash sign. The main area is on the west side of the highway and is used primarily by off road vehicles. The east side of the highway is quieter and has several pull offs available for dispersed camping.
There are no facilities; no restrooms, hookups, or trash. Pack it in, pack it out. The best time to go is in the winter months but with the weather being pretty fair it’s not too bad. You can have a fire but it depends on fire danger for the day. Pretty much if it’s hot and or dry, you won’t be able to have a fire.
It is free and first come first serve, although there are plenty of spots to go around!
All that being said, this is one of the most beautiful spots in the Sonoran desert! There are so many amazing views! Great for hiking or off roading.
Side note: Please clean up after yourself! Forest Service has put so many restrictions on this area because people leave their trash out there.
