Colorado GMU 75 Elk Hunting
La Plata and San Juan counties, southwest Colorado · 646 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 75 is like
GMU 75 spans 646 square miles across the southwestern Colorado mountains in La Plata and San Juan counties, climbing from 5,900 feet to a high of 14,100 feet with a typical elevation around 7,600 feet. The terrain is rolling to moderately steep, with 47 percent of the unit in gentle country, 30 percent moderate, and 19 percent steep slopes, interspersed with 5 percent rugged terrain. The unit sits in rugged mountain country with substantial elevation change and a mix of ridgetop and canyon systems.
The unit is approximately 43 percent open to public hunting on National Forest and BLM land, totaling around 279 square miles. Private land comprises the remaining 56 percent of the unit, with a small state trust component that is huntable only where Colorado Parks and Wildlife has enrolled it. Public access depends on trailhead availability, seasonal road conditions, and navigating the patchwork of private inholdings. Hunters should verify specific entry points and travel corridors before the season.
Elk use the unit broadly across fall and early winter. Summer Range covers 64 percent of the unit and Summer Concentration covers 9 percent, indicating clustering during the early season. Winter Range extends across 62 percent of the unit with Winter Concentration on 17 percent, showing concentrated use as conditions cool and elk shift their distribution. A small Resident Population layer (5 percent) and Migration Corridors (5 percent) reflect year-round occupancy in limited areas and movement between seasonal grounds. Hunters should expect elk distribution to shift toward winter concentration areas as the season advances into late fall, though timing and extent vary with weather and snow.
The unit offers seven seasons total: Archery (September 2–30), Muzzleloader (September 12–20), four rifle seasons spanning October 14 through November 22, and a private-land-only season (September 2–November 22). Archery and Muzzleloader coincide with the primary rut period. Early rifle seasons fall during post-rut and early migration phases, while late-season rifle hunts (November 7 onward) occur during the migration transition. Draw difficulty for the easiest adult resident bull or either-sex code is easy, often at zero preference points; however, specific rifle seasons, antlerless-only hunts, and nonresident applicants can require substantially more points. Hunter pressure is high throughout the hunting season.

Where elk live in the unit
Colorado Parks & Wildlife maps elk seasonal ranges statewide. This is how much of GMU 75 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 75 elk hunting FAQ
How much public land can a hunter actually access in GMU 75?
Approximately 43 percent of the unit, or 279 square miles, is open to public hunting on National Forest and BLM. Private land makes up 56 percent, and access to public ground depends on road conditions, trailhead availability, and navigating private inholdings. Hunters should scout access points before the season.
Is this a realistic draw for a resident with zero preference points?
Yes, for the easiest unit-wide bull or either-sex hunts available in the primary draw. Adult Colorado residents can draw some codes at zero points. Specific season combinations, antlerless-only tags, and nonresident applicants can require substantially more points.
When in the fall should a hunter expect elk to concentrate in predictable areas?
Winter Concentration covers 17 percent of the unit and becomes the focal area as the season progresses from October into November, driven by cooling temperatures and snow. However, timing and extent of the shift vary with weather, so concentration may accelerate rapidly or occur unevenly across years.
Is the archery season or rut-phase rifle season better for this unit?
Archery (September 2–30) spans the full rut onset and primary rut period, when bulls are most vocal and active. The first rifle season (October 14–18) begins after the peak rut, during post-rut recovery, when bulls are more dispersed and elk are beginning their migration transition. Archery offers more rut hunting window; rifle seasons offer other advantages.
How steep is the terrain, and can a hunter on foot cover much ground?
The unit is rolling to moderately steep overall, with 47 percent gentle, 30 percent moderate, and 19 percent steep slopes. Elevation changes from nearly 6,000 to 14,100 feet create long climbs and descents. A foot hunter can cover ground on gentle and moderate terrain, but steep sections and high elevation will limit daily range and require fitness.
Why is hunter pressure described as high if the draw is easy?
Draw difficulty and hunter pressure are separate measures. An easy-to-draw unit can still attract high numbers of hunters on public land. The tag availability is good for residents at zero points, but the number of people actually hunting the unit each season remains high, affecting crowding and elk behavior on accessible ground.

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.
