History of Arapahoe National Forest Area

Established in 1908 and named after one of the several Native American tribes who spent their summers in the Grand Lake area, the Arapaho National Forest encompasses more than 440,000 acres of mountain peaks, trails, campsites, lakes, rivers and forests in Grand County. In addition to Rocky Mountain National Park, much of the land surrounding Grand Lake is part of the Arapaho National Forest, including the Never Summer Wilderness, the Byers Peak Wilderness, the Indian Peaks Wilderness and the Vasquez Peak Wilderness.

In addition to these spectacular wilderness areas, the Arapaho National Recreation Area (ANRA) was established in 1978 as a special designation to oversee 35,000 acres of some of the finest recreational lakes in Colorado, including Lake Granby, Shadow Mountain Lake, Monarch Lake, Willow Creek Reservoir and Meadow Creek Reservoir. Together, with Grand Lake as the cherry on top, this Upper Colorado River Valley region is often referred to as “The Great Lakes of Colorado” and is a mecca for boaters, paddlers and anglers.
