On July 1, 1908 President Theodore Roosevelt established the Arapaho National Forest for the enjoyment of all. Arapaho National Forest consists of 723,744 acres and is largely in Grand and Clear Creek counties, but spills over into neighboring counties too. The forest includes the high Rockies and river valleys, straddles the Continental Divide, and is home to the Colorado River and the South Platte River.

There are six officially designated wilderness areas within the Arapaho National Forest boundaries including Byers Peak Wilderness, Indian Peaks Wilderness, James Peak Wilderness, Mount Evans Wilderness, Never Summer Wilderness, and Vasquez Peak Wilderness. The forest provides many activities for outdoorsy adventurers including hunting, fishing, off-roading, camping, hiking, snowmobiling, snowshoeing, and cross-country skiing.
