Just south of the Arizona border, Sonora’s stunning 2,700 square-mile El Pinacate and Gran Desierto de Altar Biosphere Reserve is a vast desert landscape dotted with enormous craters, sand dunes and lava flows. In 2013, it was designated a UNESCO World Heritage site for its outstanding biodiversity, including endemic species like the Sonoran Pronghorn.
