Colorado's most visited national forest, framed by Rocky Mountain peaks and ski country
White River National Forest
White River National Forest is a large protected landscape spread across northwest Colorado, encompassing roughly 2.3 million acres of Rocky Mountain terrain. It is named after the White River, which flows through the forest's northern reaches, and it spans parts of nine counties, from Eagle and Pitkin in the central Rockies to Rio Blanco and Moffat along the more open western slope country.
The forest is best known as a major hub of outdoor recreation in the American West. It contains eight designated wilderness areas, a remarkable cluster of high mountain peaks above 14,000 feet, and twelve ski areas that make it the most visited national forest in the United States. Beyond winter sports, it offers extensive road and trail networks, several large reservoirs, and habitat for a wide range of large mammals and fish.
White River National Forest plays a significant role in both Colorado's environment and its economy. It anchors the state's ski corridor around Aspen, Vail, and Breckenridge while also protecting large tracts of alpine wilderness, subalpine forest, and high-country wildlife habitat. The combination of national forest lands, officially designated wilderness, and high-mountain resort infrastructure makes it unusually varied for a single national forest unit.
