Scottsdale is a desert city in Arizona east of state capital Phoenix. It's known for its spa resorts and golf courses, including TPC Scottsdale. Farther north, trails wind through McDowell Sonoran Preserve, a desertscape of hills, rock formations and cacti. Nearby is Taliesin West, architect Frank Lloyd Wright’s former home and studio. Downtown's Old Town Scottsdale has 1920s buildings and 19th-century olive trees.
