Arapaho/Roosevelt National Forest and Pawnee National Grassland
The Arapaho/Roosevelt National Forest and Pawnee National Grassland, an enormous area that encompasses 1.5 million acres, has fishing, sailing, canoeing, and waterskiing, as well as hiking, mountain biking, birding, and camping. Contained within the Arapaho National Forest is the Arapaho National Recreation Area (ANRA), a 35,000-acre expanse adjacent to Rocky Mountain National Park that contains Lake Granby, Shadow Mountain Lake, Monarch Lake, and Willow Creek and Meadow Creek reservoirs.
