Easy trail. Start at the trailead, and you head south-southeast. The trail looks daunting from the trailhead, but don't worry. It doesn't gain elevation like Finger Rock Canyon or Ventana Canyon. If you catch a cool day when the sun is positioned just right (good luck), you'll have many opportunities for taking photos. You go up a little until you hit the junction with the faint trail to the top of Pusch Peak. The trail isn't that difficult, but you'll still feel a little bit of work. You'll follow a relatively shallow canyon up towards the junction. Go right at the junction, and you head down. Again, it's not that bad. You'll have lots of views of Oro Valley. You'll have beautiful views of a saguaro forest below, and the rock formations of Pusch Ridge above. Follow the trail down until you about level-out. Follow the trail due north until you return to the Linda Vista Trailhead. The trail will go along the east side of a school. There are spectacular views of the Tortolitas at this point. An easy after-work hike for people who live in north- and northwest metro Tucson. This trail is a great place to see the more-mundane smaller wildlife around Tucson including rabbits, doves, quail, and snakes. On a clear day you can easily see Picacho Peak.
I have heard that the trip to Pusch Peak is not "too difficult" from the junction, but it looks as if the trail to that summit should best be left to very experience hikers. That trail looks very rocky, unstable, and steep.
A good trail for those who are looking to experience as many trails in the metro Tucson area as possible.
