Nature Reserve
Reserva de la Biosfera El Pinacate y Gran Desierto de Altar
About 30km from Puerto Peñasco are the lunar landscapes of El Pinacate, one of the driest places on earth. This remote, spectacular 7145-sq-km reserve is a Unesco World Heritage site and contains ancient eroded volcanoes, giant craters, petrified lava flows, 400-plus ash cones and the continent's largest concentration of active sand dunes. Wildlife includes pronghorn antelope (the fastest land mammal in the Americas), bighorn sheep, pumas, reptiles and bountiful birdlife. There's an excellent, highly informative, solar-powered visitor center, interpretive hiking trails and two campgrounds.
