Some landscapes just beg to be explored on foot, and Arizona’s mountainous Sonoran Desert is one of them. Here, the subtleties of spiny cacti and quick-footed wildlife—plus millennia-old geological wonders and panoramic desert views—are best admired from the trails.

Scottsdale and the surrounding area offer plenty of hiking options, ranging from family-friendly paved trails to strenuous treks for the experienced. No matter how fit you may be, the Arizona desert’s dry climate and extreme temperatures can be deceptively brutal. So, be sure to bring lots of water and sun protection on any hike, as most trails have little shade and can be quite hot and dry.
