Hike the Rock Knob loop in the Estrella Mountain Regional Park in Arizona.

The Estrella Mountain Regional park south of Goodyear, Arizona contains nearly 20,000 acres of protected mountains and desert. It is located rather close to the Phoenix metropolitan area, which makes for a convenient location for a hike without a long drive. There are a number of enjoyable, well signed trails through this park. The one described here is a loop hike around a prominent feature known as Rock Knob hill.  

After parking near the Rodeo Arena, take the well signed trail heading south out of the parking area (signed as Coldwater Trail). This old jeep road is the main trail route into the desert area of the park. Since there are a myriad of trails you need to take for this loop, follow the instructions below to loop around the Rock Knob hill.

There are two highlights to this hike. The first is reached after about 1.5 miles of hiking, when you access views of the Southern part of the park. The desert goes on as far as the eye can see, and it is very easy to forget you are just a few miles from civilization.

The second highlight of the hike is reaching the highest point of the Butterfield trail, which gives nice views of the surrounding area.

Enjoy !
