Colorado GMU 55 Elk Hunting
Gunnison County, southwest Colorado · 886 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 55 is like
GMU 55 is an 886-square-mile unit in Gunnison County encompassing rolling to moderately steep terrain that spans from 7,700 feet to 14,200 feet, with a typical hunting elevation around 10,400 feet. The elevation distribution breaks down to 29% gentle, 50% moderate, and 19% steep terrain by area, making for varied country across the unit's expanse. Summer Concentration elk cluster across 59% of the unit, while Winter Concentration covers 13% of the unit; this layering indicates that elk aggregate rather than spread evenly across the landscape.
Approximately 89% of the unit consists of public land generally open to hunting, composed of National Forest (82%), BLM (6.9%), and State Wildlife Areas (0.4%). Private land comprises roughly 11% of the unit. The substantial public-land share provides access across much of the unit, though actual entry points, seasonal road conditions, and private inholdings still govern where a hunter can physically reach.
Overall Range covers the entire unit, and both Summer and Winter Range are mapped across the unit, with Summer Range covering 100% and Winter Range covering 30%. CPW also maps Migration Corridors across 34% of the unit. A hunter should expect elk to concentrate in the areas mapped as Summer Concentration through early fall, with distribution shifting as the season advances into late October and November, though the timing and extent of movement vary with weather and snow accumulation.
The unit offers six seasons: Archery from September 2 through September 30 (Either-sex); Muzzleloader September 12 through September 20 (Antlerless/Bull); 1st Rifle October 14 through October 18 (Antlerless/Bull); 2nd Rifle October 24 through November 1 (Antlerless/Bull); 3rd Rifle November 7 through November 15 (Antlerless/Bull); and 4th Rifle November 18 through November 22 (Antlerless/Bull). Archery and Muzzleloader seasons fall during the primary rut, while the four rifle seasons progress through the post-rut and migration transition phases. September temperatures average highs near 62°F and lows near 35°F with minimal snowfall, while October highs average 51°F and lows 25°F with about 2.9 inches of snowfall, and November conditions cool significantly with highs averaging 39°F and lows near 14°F accompanied by 11.5 inches of average snowfall. The draw for this unit is Easy, often requiring zero preference points for the most accessible bull or either-sex code available to adult Colorado residents, though other weapons, seasons, and nonresident applicants may require substantially more points. Hunter pressure on the unit is Moderate.

Where elk live in the unit
Colorado Parks & Wildlife maps elk seasonal ranges statewide. This is how much of GMU 55 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 55 elk hunting FAQ
How much public land can a hunter realistically access in GMU 55?
Approximately 89% of the unit—roughly 791 square miles—is public land managed by the National Forest, BLM, or State Wildlife Areas and is generally open to hunting. This represents the ground a hunter can count on accessing without crossing private land, though actual entry still depends on roads, trailheads, and seasonal closures.
Is this unit realistic for someone with no preference points?
Yes. The easiest unit-wide bull or either-sex code for adult Colorado residents draws at zero preference points, making this an accessible choice for first-time applicants. Other hunts, weapons, and nonresident applicants require more points, so the exact draw timeline depends on which season and tag type an applicant pursues.
When should a hunter focus effort in GMU 55—early or late season?
The archery and muzzleloader seasons fall during the primary rut in early September, creating opportunity for calling and rut-driven behavior. Early rifle (mid-October) still coincides with post-rut recovery when bulls remain active, while later rifle seasons from late October through November transition into the migration phase as weather cools and snow increases.
How does terrain and elevation affect hunting strategy in this unit?
Half the unit is moderate terrain with about 29% gentle ground, making much of it accessible to hunters on foot despite the 10,400-foot typical elevation. Rugged ground comprises only 2% of the unit, so steep slopes are present but not the dominant character—a hunter should expect to cover variable country rather than extreme high-alpine challenges.
Where should a hunter expect to find elk as the season progresses?
Summer Concentration mapping shows where elk cluster through early fall, covering 59% of the unit. As fall advances through October and November, CPW maps Migration Corridors across 34% of the unit, and Winter Range covers 30% of the unit; a hunter should expect elk distribution to shift toward these mapped corridors and winter areas as weather deteriorates, though timing varies with snow and temperature.
What is the character of the draw for GMU 55?
The draw difficulty is Easy, and the easiest qualifying hunts often require zero preference points for adult Colorado residents. This reflects moderate hunter pressure on the unit and reasonable tag availability, though it does not guarantee drawing—preference points still provide advantage in future years, and nonresident or later-season hunts can be more competitive.

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.
