Colorado GMU 63 Elk Hunting
Delta, Gunnison and Montrose counties, southwest Colorado · 369 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 63 is like
GMU 63 spans 369 square miles across Delta, Gunnison and Montrose counties in the southwest region, rolling terrain with some steeper breaks. The unit rises from 5,000 feet to 11,800 feet, with a typical elevation around 7,800 feet. Terrain is dominated by gentle slopes (55% of the area), with moderate slopes covering 29%, steep slopes 13%, and rugged terrain 3%. The mean slope across the unit is 12.8 degrees, falling in the moderate band.
National Forest and BLM lands make up roughly 49% of the unit and are generally open to public hunting, totaling about 181 square miles. Private ground accounts for roughly 43% of the unit. National Park Service land comprises roughly 7.8% and is closed to hunting. The remaining share is unclassified. Access to public ground depends on roads, trailheads and private inholdings, which vary across the unit.
Elk occupy the unit across a broad overall range (98% of the unit), but cluster seasonally. Summer Range covers 61% of the unit, with Summer Concentration marking 31% where elk cluster during that season. Winter Range covers 75%, with Winter Concentration on 16%. Migration Corridors span 41%. This pattern means early-season hunters should expect elk distributed across broad summer range, while fall hunters should plan for increasing movement toward winter ground as conditions cool and November approaches. The shift from summer to winter ground timing and extent vary with weather and snow.
Seven seasons are offered: Archery (September 2–30, Either-sex); Muzzleloader (September 12–20, Antlerless/Bull); 1st Rifle (October 14–18, Antlerless/Bull); 2nd Rifle (October 24–November 1, Antlerless); 3rd Rifle (November 7–15, Antlerless); 4th Rifle (November 18–22, Antlerless/Bull); and Private-land only (August 13–January 31, Either-sex/Antlerless). Archery coincides with rut onset and primary rut (September 1–30), while muzzleloader hunts during primary rut. Rifle seasons span late rut, post-rut recovery, and migration transition (October 14–November 22). September temperatures average highs of 71°F and lows of 41°F with negligible snowfall; October highs average 59°F and lows 30°F with about 1.6 inches of snow; November highs average 45°F and lows 20°F with about 6.2 inches. Hunter pressure is high on this unit. Draw difficulty for the easiest qualifying unit-wide bull or either-sex code for adult Colorado residents is easy, often requiring zero points.

Where elk live in the unit
Colorado Parks & Wildlife maps elk seasonal ranges statewide. This is how much of GMU 63 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 63 elk hunting FAQ
How much public ground can a hunter actually count on?
About 49% of the unit—roughly 181 square miles of National Forest and BLM land—is open to public hunting. The remaining publicly owned ground (7.8%) is National Park Service land where hunting is prohibited. Private land accounts for 43%. Access to the open ground depends on roads, trailheads and how private inholdings break up the public parcels.
Is this unit realistic for someone with no preference points?
Yes. Draw difficulty for the easiest qualifying unit-wide bull or either-sex code for adult Colorado residents is easy, often drawing at zero points. However, hunter pressure is high, so applicants should expect crowded conditions once in the field.
Which season offers the best chance at a bull?
Archery (September 2–30) and muzzleloader (September 12–20) occur during rut onset and primary rut, when bulls are vocal and actively moving. The 1st Rifle season (October 14–18) and 4th Rifle season (November 18–22) also allow bulls, though these fall later in post-rut recovery and migration transition when bull behavior differs.
Is the terrain steep enough to screen out casual hunters?
No. The unit is rolling with some steeper breaks; only 16% of the area is steep or rugged. Most ground is gentle or moderate slope, making the terrain accessible to hunters of varied fitness.
Where should a hunter expect to find elk early versus late in the fall?
Early-season archery and muzzleloader hunters should plan for elk distributed across summer range covering 61% of the unit. As fall progresses through October and November, conditions cool and snow accumulates, shifting elk toward winter range (75% of the unit), but the timing and extent of that shift vary with weather and snow.
Does elk distribution cluster in predictable spots?
Yes, concentrations are mapped: 31% of the unit is summer concentration (summer season) and 16% is winter concentration (winter season). However, the data does not identify where these clusters sit geographically—only that they exist on those shares of the unit. A hunter should scout or consult local knowledge to locate them.

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.
