The area contains two 14,000-foot peaks, Grays and Torreys, which are among the most frequently climbed in Colorado.
The Pawnee National Grassland is recognized as a premier birdwatching site, specifically for the Mountain Plover and the Chestnut-collared Longspur.
The Cache la Poudre River, flowing through the forest, was Colorado's first designated National Wild and Scenic River.
The forests contain the Rawah Wilderness, which derives its name from a Ute word meaning 'wild place' or 'seedy place'.
Evidence of Paleo-Indian occupation dating back 10,000 years has been identified within the boundaries of the grasslands.
The Arapaho and Roosevelt National Forests and Pawnee National Grassland represent a sprawling 1.5-million-acre expanse covering diverse ecosystems ranging from high-altitude peaks to shortgrass prairies. The landscape includes the Indian Peaks Wilderness, the Rawah Wilderness, and the Cache la Poudre Wilderness, offering extensive high-alpine lake access. Elevations span from 5,000 feet in the grasslands to over 14,000 feet on Grays and Torreys Peaks. The Pawnee National Grassland section provides a distinct flatland environment characterized by geological formations like the Pawnee Buttes. The forests support diverse wildlife including bighorn sheep, moose, and black bears. Hikers can access hundreds of miles of trails, including segments of the Continental Divide National Scenic Trail. Water-based activities are concentrated in the numerous high-altitude lakes and reservoirs managed within the forest boundaries. The area serves as a primary source for municipal water supplies in northern Colorado. Management is overseen by the United States Forest Service.

Check for fire restrictions before departing, as seasonal bans on campfires are common during dry months.
Carry a physical map and compass, as cell service is non-existent throughout most of the wilderness areas.
Practice 'Leave No Trace' principles, as these areas have limited waste management infrastructure.
Attempting high-altitude hikes without proper gear or weather monitoring, as afternoon lightning storms are frequent and hazardous.
High-altitude roads and trails remain snow-covered and inaccessible to vehicles until late June or early July.
Stay on marked trails to prevent erosion; leash pets in all developed recreation sites and wilderness areas; store food in bear-resistant containers.
