The Pinnacle Peak Summit Trail is a popular 3.5-mile round-trip hike in Scottsdale, Arizona. The trail offers stunning views of the surrounding mountains and desert landscape, and is a great place to get some exercise and enjoy the outdoors. The trail begins at the Pinnacle Peak Park trailhead, and gradually ascends through the Sonoran Desert. The first section of the trail is relatively easy, but as you get closer to the summit, the trail becomes more challenging, with some steep sections and exposed areas. The summit of Pinnacle Peak offers panoramic views of the surrounding area, including the McDowell Mountains, the Salt River Valley, and the city of Scottsdale. On a clear day, you can even see the San Francisco Peaks to the north.
