Freedom Trail (#302), also known as Piestewa Circumference, is a 3.8 mile, moderate loop trail. 

You can access this trail from all the inner trailheads. The easiest and least crowded being the Hopi Trailhead. That's the first left after the Ranger Station. The trail takes off in either direction behind the ramada. Heading clockwise you will encounter the summit trailhead in a quick 0.4 miles. Next you will take the summit trail for a half mile. At the 0.6 mile marker on the summit trail take a left onto the circumference route. This is the only left hand turn you take.Courtesy of hikearizona.com

 A lot of the trail is very rocky, but still easily manageable. There's some steep elevation gain over two periods of the hike that give you great views, but can be an intense workout depending on your fitness level. Compared to many of the surrounding trails, this is a quieter, more isolated trail that allows you to avoid the crowds, and enjoy the views of residential Phoenix adjacent to the desert vegetation of Saguaros and cacti. 

Dogs and Horses are not allowed on the Summit Trail portion of the hike. 

The Grand Canal Trail is a 23-mile long system of paved and unpaved trails located in Glendale, Phoenix and Tempe that travels through the middle of the metropolitan area. For most of the way, the trail follows alongside the Grand Canal through residential and business districts. The trail is open for bike riding, walking and running. The route of the trail reduces the number of roadway intersections, but It does have numerous roadway crossings at street level. The trail has gaps at some of the major highways, such as Highway 60 and Interstate 17, but there are underpasses for the Piestewa Freeway, the Red Mountain Freeway and Route 143.Courtesy of walkrideusa.com

Kinney Creek Trail climbs a quiet side-canyon in the Caribou-Targhee National Forest, in the Mink Creek recreation area southwest of Pocatello, Idaho. The trailhead is a small dirt pullout off the Mink Creek Road (South Bannock Highway), with no restrooms or developed facilities, which helps keep it far less crowded than the popular Cherry Springs and City Creek trails nearby.

The path follows Kinney Creek up through Gambel oak, aspen and open sagebrush slopes thick with summer wildflowers, gaining steadily as it goes. The maintained trail runs roughly two and a half miles before it begins to fade; hikers who cross the creek near the end can pick up a faint, steep route that continues to the summit of Indian Mountain, making an out-and-back of close to seven miles with well over 2,000 feet of climbing and a big payoff of ridgetop views across the Portneuf Range and the Pocatello valley.

It is a favorite of local birders, since the mix of riparian creek bottom, oak brush and open ridge draws raptors, songbirds, upland birds and waterfowl through the seasons, and of trail runners and mountain bikers looking for a workout close to town. The trail is best from spring through early fall, roughly March through September; it can be muddy at snowmelt and hot on the exposed upper slopes in midsummer. Dogs are allowed.

 This trails follows close to San Juan Rd. Part of the trail is rocky while other parts are well just dirt. Courtesy of AllTrails.com

Max Delta Trail is a 2.7 mile trail within Phoenix, Arizona on the South Mountain Preserve. This is an out-and-back trail and it is considered beginner. 

The trail has a less than 300 feet elevation gain, so you don't have to huff and puff your way up the trail, but still offers nice views of the Phoenix Valley and Gila Crossing. 

What makes this trail unique is that it there was once a mine called the "Max Delta" mine, which, of course, is what the trail is named after. On the trail you can see foundations from structures that once stood on the mountain side, with an old brick fire place that remains standing today. 

The Max Delta Mine operated in the early 1900s, supplying massive amounts of Gold, Silver, and Copper. in 1935 Max Delta Mine was the fourth largest producer of gold in the US.Courtesy of placesthatwere.com

The mine is still accessible and has an extensive system of tunnels and train tracks. However, please be aware the hazards of exploring abandoned mines; there are risks of flooding, rusty nails, falling down large drops, and rock collapses. Use caution!

This hike is a cool exploration option, and offers a neat hands on look into the history of the Phoenix area.
