Colorado GMU 77 Elk Hunting
Archuleta, Hinsdale, La Plata and Mineral counties, southwest Colorado · 557 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 77 is like
GMU 77 spans roughly 557 square miles across the southwest corner of Colorado, rising from 6,500 feet to 13,000 feet with a typical elevation around 8,700 feet. The terrain is rolling to moderately steep: 38% of the unit is gentle, 39% moderate, and 20% steep, with 3% rugged. The unit covers parts of Archuleta, Hinsdale, La Plata, and Mineral counties and offers elk hunting across a broad elevation range where high-country summer grounds transition to lower winter ranges as the season advances.
Roughly 83% of the unit is generally open to public hunting, comprising National Forest land, State Wildlife Areas, and BLM ground. The remaining 17% is private. The National Forest makes up the vast majority of public holdings. This public-land foundation gives a hunter extensive room to pursue elk, though access depends on the specific road and trailhead conditions and any seasonal closures that apply.
Elk occupy the unit across a broad range throughout the year. Summer Range covers 100% of the unit, while Winter Range covers 53%, suggesting a seasonal shift in elk distribution as the fall advances and weather drives movement toward lower-elevation winter grounds. Summer Concentration occurs on 11% of the unit and Winter Concentration on 20%, meaning elk cluster on specific portions of their respective seasonal ranges rather than spreading evenly. Migration Corridors cover 33% of the unit, reflecting the movement of animals between summer and winter grounds. Only 2% of the unit supports a year-round Resident Population, so most elk in GMU 77 migrate meaningfully.
The unit offers seven seasons in the 2026 calendar: Archery (September 2–September 30, either-sex or bull), Muzzleloader (September 12–September 20, either-sex or bull), four Rifle seasons (1st Rifle October 14–18, 2nd Rifle October 24–November 1, 3rd Rifle November 7–15, 4th Rifle November 18–22, with the first and fourth offering bull tags and the 2nd and 3rd offering antlerless only), and a Private-land-only season (September 2–November 22). Archery and Muzzleloader seasons run during the Primary Rut and Rut Onset phases, when bulls are active and vocally responsive. The early rifle seasons overlap the tail end of the rut and early post-rut recovery, while later rifle seasons fall into the migration window as elk shift toward winter range. September opens cool and dry with highs around 66°F; October brings moderate cooling and the first significant snow potential around 1.9 inches; November turns cold fast, with highs dropping to 44°F and average snowfall of 10 inches. Hunter pressure on this unit is high, but the draw difficulty is easy—often requiring zero preference points—making tags attainable for early-stage applicants on the most accessible unit-wide hunts.

Where elk live in the unit
Colorado Parks & Wildlife maps elk seasonal ranges statewide. This is how much of GMU 77 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 77 elk hunting FAQ
Can a hunter with no preference points draw this unit?
Yes. The unit draws at zero points for the easiest qualifying bull or either-sex codes in the 2026 primary draw, making it accessible to applicants at any point tier. Other seasons and weapons, as well as nonresident applicants, may require more points.
Does the unit fill with elk year-round?
Most elk migrate between seasonal ranges. Only 2% of the unit is mapped as year-round Resident Population, so expect significant elk movement as the fall progresses. Summer Range covers the entire unit, but Winter Range covers only 53%, indicating a downstream shift in distribution toward lower elevations as snow and cold advance.
When is the rut most active during the hunt season?
Archery and Muzzleloader seasons (September 2–September 20) overlap the Rut Onset and Primary Rut phases when bulls are vocalizing and responding. Early rifle seasons catch the tail end of the rut in mid-October, while later rifle seasons (starting late October) fall into the post-rut and migration window when elk have calmed and are shifting toward winter range.
How much public ground can a hunter actually hunt?
Approximately 83% of the unit is generally open to public hunting through National Forest, State Wildlife Areas, and BLM land. The National Forest comprises the overwhelming majority of this open public acreage, offering extensive space to cover, though the hunter must still evaluate specific access points, roads, and any seasonal restrictions.
How steep is the terrain, and what does that mean for foot travel?
The unit is rolling to moderately steep: 38% gentle, 39% moderate, and 22% steep or rugged combined. A backcountry hunter should expect a mix of accessible rolling ground and sustained moderate climbs, with some patches of steeper terrain that demand more effort.
When does weather turn serious for late-season hunting?
September highs average 66°F with minimal snow. October cools to highs around 55°F and brings the first meaningful precipitation (about 1.9 inches). November is a different proposition: highs drop to 44°F and average snowfall reaches 10 inches, transforming the high country and pushing elk toward lower winter 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.
