Colorado GMU 107 Pronghorn Hunting
Washington, Lincoln and Kit Carson counties, northeast Colorado · 1,241 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 107 is like
GMU 107 is a large, gentle unit of 1,241 square miles spanning Washington, Lincoln and Kit Carson counties in northeastern Colorado. The terrain is rolling and low-elevation, with a typical elevation around 5,000 feet and a range from 4,400 to 5,800 feet. Slopes across the unit are gentle, averaging just 1.5 degrees, which makes the country relatively easy to traverse on foot compared to steeper units elsewhere in the state.
Nearly the entire unit is privately owned. Public hunting is extremely limited: roughly 0.1 square mile (0.1 percent) of the unit consists of State Wildlife Areas that are generally open to hunting. An additional 2.7 percent—about 34 square miles—is Colorado State Trust Land, though access to that ground depends on whether specific parcels are enrolled in CPW's Public Access Program, so a hunter cannot count on those acres without checking enrollment first. Legal access rather than terrain difficulty is the controlling factor for most hunters here.
Pronghorn occupy the unit across all seasons, as Overall Range extends across the full 100 percent of the unit. Early fall finds pronghorn in the pre-rut and primary-rut phases, with September hunting during the transition into late rut and post-rut recovery as the season advances into October.
The unit offers two drawn seasons for pronghorn: a muzzleloader season from September 21 to September 29 (doe or buck) and a rifle season from October 3 to October 11 (doe or buck). Both seasons fall into the latter part of the rut window. Draw difficulty for the easiest qualifying hunts is easy, often requiring zero preference points, though hunter pressure across the unit is extreme.

Land & access
About <1% of GMU 107 is public land a hunter can count on — State Wildlife Areas. A further 3% 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 pronghorn live in the unit
Colorado Parks & Wildlife maps pronghorn seasonal ranges statewide. This is how much of GMU 107 each range covers — the single best clue to whether pronghorn are here in September, in November, or only passing through. The layers overlap, so they do not add to 100%.

GMU 107 pronghorn hunting FAQ
How much public land can a hunter realistically hunt in this unit?
Only about 0.1 percent of the unit—roughly 1 square mile—is State Wildlife Area that is generally open to hunting. An additional 2.7 percent is State Trust Land, but access depends on whether individual parcels are enrolled in CPW's Public Access Program. The vast majority of the unit is private, making legal access the primary limiting factor rather than terrain or pronghorn distribution.
Does this unit make sense for an applicant with zero preference points?
Yes. The easiest qualifying hunt codes in this unit draw reliably at zero preference points, so a zero-point applicant can reasonably expect to draw during the primary draw. This does not guarantee it—lower tiers sometimes draw anyway—but the draw difficulty is easy enough that no points are typically necessary for the most accessible hunts.
What is the terrain like, and how much ground can a walker cover?
The terrain is gentle and rolling across the entire unit, with slopes averaging just 1.5 degrees, making it manageable to walk compared to steeper terrain elsewhere in Colorado. However, the extreme scarcity of public access—less than 3 percent of the unit is publicly owned, and most of that is trust land with uncertain enrollment—means a hunter cannot count on covering much ground legally, regardless of how easy it is to walk.
When do the seasons fall relative to the rut?
Both seasons fall in the late stages of the rut. The muzzleloader season (September 21–29) spans the end of the primary rut and into late rut recovery, while the rifle season (October 3–11) falls entirely within late rut and post-rut recovery. Hunters should expect pronghorn behavior influenced by breeding activity throughout both hunts.
Are there over-the-counter archery licences available?
The data for drawn seasons does not include a limited archery hunt code for this unit. Whether archery pronghorn licences are sold over the counter here would require checking CPW's current offerings, as over-the-counter licences are not part of the draw system.
Why is this unit listed as 'extreme' hunter pressure if the draw is easy?
Draw difficulty and hunter pressure are separate measures. An easy draw means few or no preference points are needed to hunt, but it also means many applicants can draw, leading to crowded hunting conditions on the ground. The ease of drawing combined with limited public land creates high pressure on whatever open ground exists.

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.
