Colorado Parks and Recreation
With some of the most beautiful mountains in the world, opportunites for outdoor adventure in Colorado abound. The state's natural beauty is becoming better protected with over 40 State Parks, 6 Federal Parks, a myriad of Federal Wilderness areas, a host Bureau of Land Management land, and 13 National Forests and Grasslands. The total acreage of these sites is almost a third of the state, the government owns roughly 45% of the state's land. In Colorado the Forest Service, Bureau of Land Management, Fish and Wildlife Service, and the National Park Service managed 23,455,115 acres in 1994. Since then there have been two new Wilderness Acts that have increased that number.
These sites are open to the public, but have rules a regulations governing each. For instance you are allowed to camp only in designated spots for campgrounds in Rocky Mountain National Park.
Several of the large lakes and reservoirs also fall into the boundaries of these sites.
