The protected desert north-east of central Scottsdale runs from a few hundred metres above the city to the summit of Thompson Peak at 3,900 feet, with around 230 miles of marked trails — short loops, ridge walks, technical mountain-bike routes, and a series of trailheads each with its own personality.
The Gateway Trailhead off Bell Road is the easiest start, with a flat loop suitable for almost anyone. Pinnacle Peak, on the northern edge, has a popular three-mile out-and-back over granite boulders to a 3,170-foot summit. For serious hikers the Tom's Thumb trail climbs to a famous rock formation high on the McDowell range. Carry far more water than you think you need; the desert dehydrates faster than the city.
