The connection that Coloradans feel to the natural world can be measured each season by road miles ridden, vertical feet hiked, and sections of rivers fished. More than 35% of land area in Colorado is protected public land. That means wildlife is free to roam in natural habitats, native plant life is conserved, and we have an almost endless number of places in which to play and explore. The Colorado National Forests, one type of protected public land, make up more than 13 million acres of total public land acreage and are home to some of the most breathtaking landscapes in the Rocky Mountain region.
