Loews Ventana Canyon Resort
Within minutes of leaving the resort's tony confines, you can hike into some genuine, 100 percent American wilderness.
The monumental resort sits at the head of its namesake canyon in the foothills of the Santa Catalina Mountains, where saguaros crowd the slopes and huge boulders fill the canyon bottom.
About 2½ miles of hiking offers a taste of the canyon's beauty, but if you're inspired, the trail climbs more than 3,000 feet into the heart of the Catalinas. —Matthew Jaffe
