Explore the great outdoors by visiting America’s backyard -- 193 million acres of national forests and grasslands. Find your perfect spot on these expansive lands that include more than 4,300 campgrounds and 158,000 miles of trails, including 31,900 miles on pristine wilderness areas.
Discover our rich cultural heritage at such destinations as Chimney Rock National Monument. Step back into time by stepping on tracks left 150 million years ago by dinosaurs at the Picket Wire Trail in southeast Colorado, where you also can see Native American rock art, ruins from the Dolores Mission and Cemetery and the old Rourke cattle ranch.
These lands also play host to more than 6,000 miles of wild and scenic rivers that offer leisurely rides passed awe-inspiring scenery or breathtaking rollercoaster-like rides down rapids. We are your year-round destination, including skiing on one of the 122 ski areas in the winter, photographing the bursting colors of wildflowers, cooking s’mores around the campfire in the summer or watching leaves change colors in the fall.
