Colorado GMU 80 Elk Hunting
Alamosa, Conejos, Mineral and Rio Grande counties, southwest Colorado · 887 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 80 is like
GMU 80 spans 887 square miles across the southwest region of Colorado, straddling Alamosa, Conejos, Mineral, and Rio Grande counties. The terrain is rolling, with some steeper breaks, rising from a low of 7,500 feet to a high of 13,200 feet, with typical elevation around 8,500 feet. The unit is characterized by 60% gentle terrain, 31% moderate slopes, and 9% steep terrain. Elk hunting here encounters moderate hunter pressure overall.
The unit is approximately 55% generally open to public hunting—roughly 486 square miles of National Forest, BLM, and State Wildlife Areas. An additional 1.5% (about 14 square miles) is Colorado State Trust Land, huntable only on parcels enrolled in CPW's Public Access Program; access to this ground varies. Approximately 2.7% is unclassified in the ownership records. Private land comprises about 41% of the unit. Public ownership is not the same as easy entry; hunters should verify roads, trailheads, and access conditions before applying.
Seasonally, elk occupy broad ranges across the unit. Winter Range covers 45% and Summer Range covers 43%, with Winter Concentration marking 24% and Summer Concentration at 10%. Resident Population mapping indicates year-round use over about 5% of the unit, suggesting some elk remain through the calendar. Migration Corridors account for 4%. As fall advances from September into November, elk should be expected to shift toward winter ground, though the timing and extent of that movement vary with weather and snow. Hunters should anticipate concentrated elk in winter and summer concentration areas rather than uniform distribution across the broad seasonal ranges.
The unit offers seven seasons, six of which are open to the public. Archery runs September 2–September 30 for either-sex hunting, overlapping the rut onset and primary rut phases. Muzzleloader is September 12–September 20 for antlerless or bull, during the primary rut. Four rifle seasons follow: 1st Rifle October 14–October 18 for bull only; 2nd Rifle October 24–November 1 for antlerless; 3rd Rifle November 7–November 15 for antlerless; and 4th Rifle November 18–November 22 for antlerless or bull. The 1st Rifle season falls in the late rut and early post-rut phases, while 2nd and 3rd Rifle seasons occur during the migration transition. September temperatures average highs around 70°F and lows around 37°F with minimal snowfall. October cools to highs around 60°F and lows around 27°F with about 1 inch of snowfall. November brings significant cooling to highs around 46°F and lows around 16°F, with about 4.4 inches of snowfall. The draw for this unit is easy—the easiest qualifying unit-wide bull or either-sex code typically draws at zero preference points—though some premium bull seasons require substantially more points. Other weapons, seasons, and nonresident applicants may face different draw difficulty.

Land & access
About 55% of GMU 80 is public land a hunter can count on — National Forest, BLM and State Wildlife Areas. A further 2% is State Trust Land, which is huntable only where CPW has enrolled it.
- National Forest44%
- BLM11%
- State Wildlife Area<1%
- State Trust Land2%
- Unclassified ownership3%
- Private41%
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 80 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 80 elk hunting FAQ
Can someone with zero preference points draw a tag on GMU 80?
Yes. The easiest unit-wide bull or either-sex code draws reliably at zero preference points for adult Colorado residents. However, some premium bull seasons within the unit require substantially more points, and muzzleloader or rifle-only hunts may differ from archery.
Is there reliable public ground to hunt, or is most of it private?
Approximately 55% of the unit is generally open to public hunting on National Forest, BLM, and State Wildlife Areas. An additional 1.5% is State Trust Land accessible only where CPW has enrolled it in the Public Access Program. Private land comprises about 41%, which can fragment the landscape. Hunters should confirm access and road conditions before committing to the application.
How much of the unit stays occupied year-round versus seasonally?
CPW maps year-round use on about 5% of the unit under Resident Population. The remaining elk use is seasonal: Winter Range covers 45% and Summer Range covers 43%, indicating substantial seasonal movement. Hunters should expect elk to shift toward winter concentration areas as fall progresses and weather changes, though timing varies by year.
Which season offers the best chance at a calling bull?
Archery (September 2–September 30) and Muzzleloader (September 12–September 20) both occur during rut onset and the primary rut, when bulls respond most predictably to calling. Archery runs longer and allows bugling throughout the primary rut phase, whereas Muzzleloader is a shorter, intermediate-range window.
Does the terrain require extreme fitness or is it manageable for an average hunter?
The unit is rolling with some steeper breaks rather than rugged. Sixty percent is gentle terrain, 31% is moderate slopes, and only 9% is steep. A reasonably fit hunter on foot can reach and hunt much of the public ground, though elevation gain to 13,200 feet and snow in November will still demand conditioning.
Is the fall here cold and snowy early in the season?
September is mild, with highs around 70°F and virtually no snow. October cools to highs around 60°F with about 1 inch of snowfall. November is significantly colder and wetter, with highs around 46°F and about 4.4 inches of snowfall, making the latter part of the season more challenging for access and foot traffic.

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.
