Colorado GMU 52 Mule Deer Hunting
Delta and Gunnison counties, southwest Colorado · 264 sq mi
Based on the EASIEST unit-wide buck 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 52 is like
GMU 52 spans 264 square miles across Delta and Gunnison counties in southwest Colorado. The unit rolls through terrain characterized by gentle slopes, with some steeper breaks; 63% of the area is gentle, 33% moderate, and 4% steep. Elevation spans from 5,000 feet to 11,300 feet, with a typical elevation around 7,700 feet. The terrain and elevation range support mule deer across multiple seasonal ranges throughout the fall.
The unit is roughly split between public and private ground. National Forest and BLM lands comprise approximately 48% of the unit and are generally open to public hunting, providing about 126 square miles of accessible terrain. Private land makes up the remaining 52%. Public ownership alone does not guarantee easy access; roads, trailheads, seasonal closures, and private inholdings all affect what ground a hunter can actually reach and hunt.
Mule deer occupy summer range across 99% of the unit through early fall. Winter range covers 55% of the unit, and winter concentration—where deer cluster—covers 42%. As the season progresses from September through November and snow accumulates, deer are expected to shift toward winter ground, though the timing and extent of that movement vary with weather conditions. Hunters should anticipate higher concentrations of mule deer on winter-concentration ground as the season advances.
GMU 52 offers six mule deer seasons in total. Five are available to public applicants: archery (September 2–September 30, buck); muzzleloader (September 12–September 20, buck); three rifle seasons—2nd Rifle (October 24–November 1, buck), 3rd Rifle (November 7–November 15, buck), and 4th Rifle (November 18–November 22, buck). A sixth season is private-land only (August 15–November 15, either-sex/doe/buck). The archery and muzzleloader seasons fall during the velvet-shed period when bucks are still in bachelor groups. The 2nd Rifle season spans the early fall migration and early pre-rut phases. The 3rd Rifle and 4th Rifle seasons occur during the pre-rut and primary rut, when buck behavior shifts significantly. The draw for public seasons is easy—often at zero preference points for the most accessible hunts—though hunter pressure is extreme. September temperatures average highs near 70°F and lows near 43°F with minimal snowfall; October highs drop to the upper 50s with about 1 inch of snowfall; by November, highs fall to the mid-40s with over 5 inches of snowfall expected.

GMU 52 mule deer hunting FAQ
Can a hunter with zero preference points draw a public archery or rifle tag here?
Yes. GMU 52 draws at zero preference points for the easiest unit-wide buck hunts available to adult Colorado residents. This applies to the most accessible seasons and codes; other weapons, seasons, and nonresident applicants can require substantially more points. The draw is easy, but that does not mean every application succeeds—check the specific hunt code when applying.
How much public ground can a hunter actually access and hunt?
About 126 square miles of National Forest and BLM land are generally open to public hunting—roughly 48% of the unit. Access depends on roads, trailheads, and whether private inholdings or seasonal closures block the way. The remaining 52% is private land. A hunter should scout the specific area and approach before committing to the unit.
Is this a good early-season choice, or should a hunter wait for the rut?
The September archery and muzzleloader seasons occur when bucks are still in velvet shed and bachelor groups, before the rut begins. The 3rd Rifle and 4th Rifle seasons (November 7–22) fall during the pre-rut and primary rut when buck behavior is more aggressive and visible. Early-season hunters target bachelor-pattern bucks; late-season hunters hunt during the rut.
Where should a hunter expect to find mule deer as the season progresses?
Summer range covers 99% of the unit in early fall, but winter range covers only 55% and winter concentration covers 42%. As snow accumulates from October through November, deer are expected to shift toward winter ground and concentrate in specific areas. The timing and extent of that shift depend on weather and snow; a hunter should be prepared to move higher or lower as conditions change.
Is the terrain steep and difficult to hunt on foot?
The unit is mostly gentle to moderate; 63% is gentle and 33% is moderate, with only 4% steep. A hunter on foot can cover ground without extreme exposure, though the moderate slopes and elevation range (5,000–11,300 feet) still require fitness and preparation. The rolling terrain with some steeper breaks is manageable for most capable hunters.
How crowded is this unit in fall?
Hunter pressure is extreme. The easy draw and public land availability in a southwest Colorado location draw large numbers of applicants and hunters. Although the draw itself is not competitive, a hunter should expect to share the ground and plan accordingly, especially during the rifle seasons and rut.

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.
