Colorado GMU 6 Elk Hunting
Jackson County, northwest Colorado · 354 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 6 is like
Colorado GMU 6 covers 354 square miles in Jackson County in the northwest region, rising from 7,700 feet to a high of 12,900 feet, with a typical elevation around 8,400 feet. The terrain is rolling, with some steeper breaks, dominated by gentle slopes that account for 69 percent of the unit's area, moderate slopes for 25 percent, and steep terrain for 6 percent. The country transitions from lower-elevation foothills through mid-elevation basins and ridges to higher alpine terrain as elevation increases.
Public hunting access covers approximately 30 percent of the unit—roughly 108 square miles—on BLM land, National Forest, and State Wildlife Areas. Colorado State Trust Land makes up another 9.5 percent (about 34 square miles), though hunting there is access-dependent and limited to parcels enrolled in CPW's Public Access Program. The remainder, about 59 percent, is private land. This public-ownership distribution means legal access is the primary constraint on where hunters can pursue elk across this unit.
Elk occupy the unit across a broad range of elevations through the fall. Winter Range covers 66 percent of the unit, with 26 percent mapped as Winter Concentration, indicating that as temperatures drop and snow accumulates through November and into December, elk cluster on specific ground rather than spreading uniformly. Summer Range extends across 42 percent of the unit, with only 2 percent marked as Summer Concentration, suggesting elk are more dispersed during the warm months. The shift from dispersed summer distribution to concentrated winter use is characteristic of how this unit's seasonal ranges operate, with elk responding to seasonal weather and elevation changes.
GMU 6 offers eight seasons total, including six open to public applicants. Archery runs September 2 through September 30 as either-sex or antlerless. Muzzleloader is September 12 through September 20, either-sex or antlerless. Four rifle seasons follow: 1st Rifle October 14 through October 18 (either-sex or antlerless), 2nd Rifle October 24 through November 1 (antlerless), 3rd Rifle November 7 through November 15 (antlerless), and 4th Rifle November 18 through November 22 (either-sex or antlerless). Archery coincides with the rut onset and primary rut phases, making September a prime time for calling and bugling. Muzzleloader straddles the tail end of the primary rut. By the time rifle seasons arrive, the rut is in recovery or transition phases, and the unit is cooling rapidly—October midmonth highs drop to 53°F and November highs to 40°F. This unit draws as easy for the most accessible bull or either-sex hunts, often at zero preference points for an adult Colorado resident, though other weapon types, seasons, and nonresident applicants can require substantially more points. Hunter pressure on the unit is extreme.

Land & access
About 30% of GMU 6 is public land a hunter can count on — BLM, National Forest and State Wildlife Areas. A further 9% is State Trust Land, which is huntable only where CPW has enrolled it.

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.
Where elk live in the unit
Colorado Parks & Wildlife maps elk seasonal ranges statewide. This is how much of GMU 6 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 6 elk hunting FAQ
How much of this unit can a public-land hunter actually access?
Approximately 30 percent of GMU 6 is generally open to public hunting on BLM, National Forest, and State Wildlife Areas. An additional 9.5 percent is Colorado State Trust Land, huntable only if enrolled in CPW's Public Access Program—check current enrollment before planning a hunt. The remaining 59 percent is private land, making legal access the primary constraint even where terrain is walkable.
Is this unit realistic for someone with no preference points?
The easiest bull or either-sex hunts in GMU 6 draw at zero preference points, making it accessible to adult Colorado residents applying for the first time. However, this easy draw comes with extreme hunter pressure, so success depends more on strategy and effort than on the tag itself. Other weapon types, specific seasons, and nonresident applicants face substantially higher point requirements.
Which seasons offer the best window for hunting the rut?
Archery from September 2 through September 30 covers the entire rut onset and primary rut phases, offering the longest window for calling and bugling. Muzzleloader from September 12 through September 20 falls within the primary rut, also prime for vocal tactics. By the time the first rifle season opens on October 14, the primary rut has ended and bulls are in recovery or transition, though still responsive.
Does elk distribution shift significantly as fall progresses?
Yes. Summer Range covers 42 percent of the unit with minimal concentration, indicating elk are relatively dispersed during warm months. Winter Range covers 66 percent with 26 percent marked as Winter Concentration, meaning elk cluster on specific ground as temperatures drop and snow accumulates through fall. A hunter should expect this shift to accelerate as November arrives and snowfall increases.
Is the terrain here manageable for a hunter on foot?
The terrain itself is manageable: 69 percent of the unit is gentle slope and 25 percent is moderate, with steep terrain accounting for only 6 percent. However, terrain walkability and legal access are separate concerns—only 30 percent of the unit is dependably open to public hunting. A hunter can cover ground readily on accessible public land, but the mix of private inholdings and State Trust Land parcels determines how far a hunter can actually go.
What should I expect for weather conditions across the fall hunting seasons?
September offers mild conditions with highs near 67°F and minimal snowfall. October cools significantly, with midmonth highs dropping to 53°F and about 3.6 inches of average monthly snowfall. By November, highs fall to 40°F with about 10 inches of average monthly snowfall, creating conditions where weather and snow can shift elk distribution rapidly. Plan for cooling and increasing precipitation as the season progresses.

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.
