Phoenix spreads across the Sonoran Desert beneath Camelback Mountain and South Mountain. The Desert Botanical Garden shows desert plants from around the world along trails that bloom in spring, Papago Park holds red sandstone buttes and the Hole in the Rock formation, and South Mountain Park and Preserve offers desert trails with views across the Valley. The Heard Museum presents Native American art and history, the Phoenix Art Museum covers American, European, and Latin American work, and Roosevelt Row brings murals, galleries, and small studios to downtown streets.
