Colorado GMU 191 Elk Hunting
Larimer County, northeast Colorado · 317 sq mi
Based on the EASIEST unit-wide bull or either-sex hunt code available to adult Colorado residents in the 2026 primary draw — the lowest preference-point tier that drew reliably. Private-land-only and Ranching for Wildlife hunts are excluded because neither is a unit-wide public-land opportunity — NOT because the public cannot draw them. A private-land-only license requires the hunter's own permission to hunt private ground; a Ranching for Wildlife license is valid on the participating ranches enrolled in that program. They are separate systems. Other weapons, seasons and nonresident applicants can require substantially more points. The band is a floor, not a target: even the easiest qualifying hunt here sits in that range.
What hunting GMU 191 is like
GMU 191 spans 317 square miles in Larimer County and ranges from 5,200 feet to 8,900 feet, with a typical elevation around 7,000 feet. The terrain is rolling to moderately steep, with 43% gentle slopes, 41% moderate, 15% steep, and 1% rugged by area. The unit combines low-elevation foothill country with mixed-elevation terrain suitable for early and late season hunting.
Generally open public land comprises about 44% of the unit, primarily National Forest, State Wildlife Areas, and BLM. An additional 5.5% consists of Colorado State Trust Land where access depends on enrollment in the Public Access Program; hunters should verify which parcels are open before planning. Private land makes up 48% of the unit, and approximately 2.8% is unclassified. The checkerboard of public and private ownership means that accessing public ground often requires identifying specific parcels and approach routes rather than assuming open travel across large blocks.
Winter Range covers 76% of the unit and Winter Concentration covers 41%, indicating that fall and early winter concentrate elk significantly across much of the landscape. Resident Population use spans 17% of the unit year-round, while Summer Range covers only 5% and Migration Corridors 4%. As the season progresses from early autumn through November, expect elk to shift toward winter concentration ground; timing and extent of this movement vary with weather and snow. The limited Summer Range share means most of the unit's resident elk are not present in June and July.
The unit offers seven public seasons: Archery (September 2–30, either-sex), Muzzleloader (September 12–20, bull or antlerless), and five rifle seasons spanning October 14 through December 9. The four numbered rifle seasons run October 14–November 22, followed by a separate Late Rifle season November 28–December 9. Archery overlaps the rut onset and primary rut; muzzleloader hunts during the primary rut; early rifle hunts (1st and 2nd) occur as the rut ends and transitions to post-rut recovery; late rifle seasons coincide with migration and winter range use. The unit draws with easy difficulty—often requiring zero preference points—for the easiest qualifying adult resident bull or either-sex code, though other seasons and nonresident applicants face substantially higher competition. Hunter pressure on the unit is extreme.

Land & access
About 44% of GMU 191 is public land a hunter can count on — National Forest, State Wildlife Areas and BLM. A further 6% is State Trust Land, which is huntable only where CPW has enrolled it.
- National Forest33%
- State Wildlife Area10%
- BLM<1%
- State Trust Land6%
- Unclassified ownership3%
- Private48%
Colorado State Trust Land is open to public hunting only where it is enrolled in CPW's Public Access Program. Check current enrollment before planning around it.
“Ownership unclassified” means the source dataset does not record an owner for that acreage. It is not known to be public or private.
Where elk live in the unit
Colorado Parks & Wildlife maps elk seasonal ranges statewide. This is how much of GMU 191 each range covers — the single best clue to whether elk are here in September, in November, or only passing through. The layers overlap, so they do not add to 100%.

GMU 191 elk hunting FAQ
Can a hunter with zero preference points draw an elk tag here?
Yes. The unit draws at easy difficulty for the easiest unit-wide bull or either-sex code available to adult Colorado residents, meaning zero preference points are often sufficient. However, this easiest tier does not describe all hunts—rifle seasons, muzzleloader, and nonresident applicants face substantially more competition and require higher point counts.
How much public land can actually be hunted?
Approximately 44% of the unit is generally open to public hunting, mainly National Forest, State Wildlife Areas, and BLM. An additional 5.5% is State Trust Land where access depends on Public Access Program enrollment and must be verified before the hunt. Hunters should identify specific parcels and approach routes, as private land and unclassified acreage create access barriers.
When do elk concentrate in this unit?
Winter Concentration covers 41% of the unit, and Winter Range extends over 76%, meaning elk cluster significantly as fall progresses into late season. The limited Summer Range (5%) indicates most elk move to or concentrate on winter ground by late fall, though the timing depends on weather and snow conditions.
Is this unit better for archery or rifle?
Archery runs September 2–30 during rut onset and primary rut when bulls are vocally active, making it attractive for callers. Rifle hunters have five options from October through early December, with early rifle seasons arriving after the rut peaks and later seasons coinciding with migration and winter concentration. Choice depends on weapon preference and willingness to hunt during different rut phases.
What is the weather like during the main seasons?
Early season (September) averages highs near 70°F with minimal snow. October cools to highs around 56°F with about 2.3 inches of monthly snowfall. November sees highs around 44°F and 3.4 inches of snowfall, creating conditions that shift elk toward winter ground. The fall cools steadily from September through November.
How crowded is this unit?
Hunter pressure is extreme on this unit. Despite easy draw difficulty, access to public land is limited by private inholdings and an access-dependent State Trust Land share, concentrating hunters on available open ground. Hunters should prepare for significant pressure, especially during popular seasons.

Draw difficulty is a qualitative band, not published odds — the note under the summary above states exactly which hunt code it describes. Land shares are separate, non-overlapping categories: publicly owned is not the same as open to hunting, and State Trust Land is huntable only where CPW has enrolled it.
