Unit 191, Colorado

Elevation ranges from approximately 4,921 feet along the eastern edge near Fort Collins to 12,795 feet at the highest point in the southwestern portion of the unit. The lower and middle reaches consist of rolling ridges divided by numerous creek drainages, with broad valley flats transitioning into steeper foothills. The upper elevations, particularly within the Rawah Wilderness (48,930 acres, peaks to 12,951 ft) and Comanche Peak Wilderness (66,791 acres, elevations 8,000–12,702 ft), feature glacially carved U-shaped valleys, cirque lakes, and alpine ridgelines. Approximately 80 percent of the public land area has a slope of 27 degrees or less, but many drainages are sharply incised.

The primary paved corridor into the western and upper portions of the unit is Colorado Highway 14 (the Cache la Poudre–North Park Scenic Byway), which follows the Cache la Poudre River west from Fort Collins through Poudre Canyon before cresting Cameron Pass. At approximately 52 miles west of Fort Collins on CO 14, County Road 103 (Laramie River Road) turns north and drops into the Laramie River Valley, serving the Rawah Trailhead (15-vehicle/4-horse-trailer lot, vault restroom) at its northern terminus 13 miles from CO 14. US Highway 287 provides the main northern access corridor; from Fort Collins, travel 22 miles north on US 287 to Cherokee Park Road (CR 80C), then 6 miles west to the Cherokee State Wildlife Area parking area. Eagle's Nest Open Space (755 acres, Larimer County) is accessed via US 287 north to Livermore, then west on Red Feather Lakes Road (CR 74E) roughly one-third mile; all hunters must use the Eagle's Nest parking lot — no parking on Rattlesnake Road. Note: only archery and muzzleloader hunting are permitted on weekdays within Eagle's Nest boundaries; rifles and small game hunting are NOT allowed. The Rawah Wilderness and Comanche Peak Wilderness are non-motorized only — no motorcycles, bicycles, or mechanized transport — and the most remote drainages are foot or horse access only. Laramie River Road is heavily used by snowmobiles in winter and access is seasonally limited by snow, typically mid-fall through late spring. Cherokee SWA is open for hunting and fishing September 1–May 1; foot access only after the last big-game season (horses allowed on designated roads and trails at other times). The unit sits entirely within the Canyon Lakes Ranger District of the Arapaho and Roosevelt National Forests. Some roads in the unit sustained damage in the 2013 Front Range floods. There is a checkerboard of private land throughout the lower and mid-elevation portions of the unit; 49 percent of the unit is private, requiring hunters to confirm land status before accessing parcels.

Vegetation shifts dramatically by elevation. At lower elevations (roughly 4,900–6,500 ft) sagebrush flats, native grasslands, pinyon pine, and juniper dominate, with ponderosa pine and oakbrush appearing on south-facing slopes and cottonwoods lining creek bottoms. Middle elevations (6,500–9,500 ft) transition into mixed ponderosa, oakbrush, mountain mahogany, and rabbitbrush foothills; scattered aspen groves increase with elevation. Upper montane and subalpine zones (9,500–11,500 ft) are characterized by dense spruce-fir forest, large aspen parks, and open grass-and-wildflower ridges. Above treeline (roughly 11,500 ft and higher) alpine tundra, rock fields, and glacial lakes define the Rawah high country. Riparian willows, alders, and sedge meadows follow the Cache la Poudre River, North Fork of the Cache la Poudre, and Laramie River corridor through the unit.

Elk are the primary big game, with summer range concentrated between 9,500 and 11,500 feet in the Rawah and Comanche Peak high country; rut activity typically begins the first week of September and runs approximately one month. As fall weather moves in, elk migrate toward lower-elevation winter range along the Laramie River corridor near the Wyoming border. Mule deer range from about 5,000 to 11,500 feet in summer and rut from late October into December. Pronghorn are present in the unit, using sagebrush and grassland habitats at lower elevations. Shiras moose were reintroduced to North Park in the late 1970s and the Laramie River Valley population (near Glendevey) is established; moose favor riparian willows and wetlands throughout the drainage system. Black bears are common throughout the forested mountains and foothills. Mountain lions range across all elevations. Wild turkeys occupy lower and mid-elevation oak and ponderosa habitat. Bighorn sheep are occasionally sighted in the Rawah high country (confirmed via Wilderness.net). Non-game species include beaver, cutthroat trout (including the endangered greenback cutthroat), and forest birds including ptarmigan at high elevations.

1. Season dates corrected to 2026 CPW structure per Storm Peak Outfitters (sourced from CPW): Archery Sept 2–30, Muzzleloader Sept 12–20, 1st Rifle Oct 14–18, 2nd Rifle Oct 24–Nov 1, 3rd Rifle Nov 7–15. The draft's dates were off by one day throughout. 2. 4th rifle season removed from confirmed dates — not mentioned in Storm Peak Outfitters 2026 listing; hunters should verify with CPW brochure. 3. Eagle's Nest Open Space restriction added: rifles and small game hunting NOT permitted within its boundaries; archery/muzzleloader weekdays only. 4. Unit-level harvest statistics were not publicly accessible in machine-readable form; GoHunt notes 'low draw odds' for this unit. 5. Public land percentage (51%, or 50.7% per GoHunt) confirmed. 6. Rawah Wilderness (48,930 acres, 12,951 ft peak), Comanche Peak Wilderness (66,791 acres, 8,000–12,702 ft), and Cherokee SWA (25,497 acres, GMUs 8 and 191) figures all confirmed from primary sources. 7. Antler restriction (4 points on one antler OR brow tine 5 inches or longer) for bull elk in GMU 191 — verify annually with CPW regulations. 8. The boundary between GMUs 8 and 191 was realigned per CPW; hunters should verify current boundaries using CPW's official GMU maps.
