Located in the Rocky Mountains and foothills of north central Colorado, are the Arapaho and Roosevelt National Forests and Pawnee National Grassland. Some campgrounds can be found as high as 12,000'. Trout fishing is very popular and certain locations are catch-and-release and/or artificial flies and lures only. Congress designated the upper stretch of the river west of Poudre Park as the Cache la Poudre Wild and Scenic River because of its outstanding recreation and scenic features. Enjoy camping, picnicking, fishing, horse riding, mountain biking, hiking, and white-water rafting and kayaking, hunting other activities. Congress designated five scenic byways for their spectacular scenery, wildlife, or history. Guanella Pass, Peak to Peak, Mount Evans, Cache la Poudre-North Park, and Pawnee Pioneer Trails byways are passenger car accessible. The Pawnee National Grassland located approximately 30 miles east of Fort Collins, Colorado, is fairly level in elevation. The grassland is criss-crossed with eroding creek drainages, and elevations range from 4,900' on the prairie to 5,500' at the summit of the Pawnee Buttes.
