Free access to 30,000 acres of protected Sonoran Desert with 225 miles of trails, from flat interpretive paths to summit scrambles.
The McDowell Sonoran Preserve covers more than 30,000 acres of Sonoran Desert terrain within the city limits of Scottsdale, making it the largest urban preserve in the country. Eleven trailheads provide access to more than 225 miles of trails that range from flat, accessible interpretive paths to technical summit scrambles with significant elevation gain. The main Gateway Trailhead at 18333 North Thompson Peak Parkway is the primary access point, with trail maps, parking, and ranger information.
The preserve offers a direct, unmediated experience of the desert landscape that the golf courses frame and manicure. Saguaro forests, desert washes, wildflower corridors in spring, and mountain views in every direction provide the visual experience. The silence, once you are a half-mile from the trailhead, is the unexpected feature: the desert quiet is tangible, and it resets the senses after the social environment of a golf resort.
The preserve is open sunrise to sunset daily. No entry fee. Guided hikes with naturalist commentary run $40 to $60 through various operators. Morning hikes are recommended in all seasons; from May through September, starting at sunrise is essential, as temperatures climb rapidly after 9 AM. Trail difficulty ranges widely, and the Gateway loop trails provide an accessible introduction. Water, sun protection, and closed-toe shoes are mandatory. The preserve sits in north Scottsdale, roughly 15 minutes from Old Town.
Free access to 30,000 acres of protected desert, with trail options for every fitness level, makes the preserve the most accessible and cost-effective activity in the Scottsdale inventory. For companions who want to experience the desert without a vehicle or a tour guide, the preserve delivers an independent, self-paced alternative.
