Colorado Unit 161 Moose Hunting Guide
The Bottom Line on One of Colorado's Premier Moose Units
Colorado Unit 161 sits in the western slope of the state, occupying roughly 261,039 acres with 74% public land access and elevations ranging from 7,811 to 12,102 feet. For hunters pursuing a Shiras' moose tag in Colorado, this unit consistently delivers some of the most compelling harvest numbers in the state — and the trophy history backing up those numbers makes it worth serious consideration for any applicant willing to invest in the process.
Moose hunting in Colorado is among the most limited-entry big game experiences in the West. Tags are extraordinarily scarce statewide, and Unit 161 is no exception. What sets this unit apart is the sustained harvest performance across multiple seasons and a landscape that offers a genuine mix of accessible public terrain and true backcountry hunting. With 23% of the unit designated as wilderness, hunters have options ranging from road-accessible glassing setups to deep wilderness pack-in hunts — though that wilderness acreage carries meaningful implications for nonresidents planning their approach.
This article draws on harvest data and application information compiled by HuntPilot to give hunters a clear picture of what Unit 161 actually produces and what it takes to get a tag in hand.
Harvest Success Rates
Unit 161's moose harvest data tells a consistent story: when hunters draw a tag here, they kill animals at exceptional rates. The following figures reflect unit totals across recent seasons:
- 2025: 41 hunters, 32 harvested — 78% success
- 2024: 19 hunters, 16 harvested — 84% success
- 2023: 21 hunters, 18 harvested — 86% success
- 2022: 18 hunters, 16 harvested — 89% success
- 2021: 15 hunters, 18 harvested — 120% success
- 2020: 13 hunters, 15 harvested — 115% success
- 2019: 13 hunters, 15 harvested — 115% success
A few important notes on reading these numbers. The 2019–2021 seasons show success rates exceeding 100%, which occurs in harvest reporting when hunters harvest more animals than the initial hunter count — typically when some hunters fill multiple tags (cow tags alongside bull tags) or when reporting methodology counts tags issued rather than unique hunters in the field. This is a data artifact, not a statistical anomaly suggesting a moose-per-hunter ratio above one.
The more meaningful trend is the floor: harvest success has not dropped below 78% in any of the seven seasons on record, and it held above 84% in four of the six years from 2019–2024. That kind of floor is rare in any big game hunt, anywhere in the West.
The 2025 season shows a meaningful jump in hunter count — from 19 hunters in 2024 to 41 hunters — alongside a modest dip in success rate to 78%. This is worth watching. Larger tag allocations sometimes correlate with slightly lower per-hunter success as hunting pressure increases, but 78% on a larger sample year is still a strong result and does not suggest any structural problem with the unit.
Trophy Quality
The counties overlapping Unit 161 carry a strong history of trophy production for Shiras' moose. Based on available trophy records, the area demonstrates consistent trophy-class animal production over multiple decades. Hunters who draw a tag in this unit are hunting in country with legitimate trophy pedigree.
A critical caveat applies here: trophy records are logged by county, not by hunt unit. The trophy history attributed to the counties overlapping Unit 161 is shared with neighboring units that overlap the same county boundaries. The same records cannot be assigned exclusively to Unit 161 — any neighboring unit in those same counties has equal claim to that trophy history. What the data does confirm is that the broader landscape of which Unit 161 is a part has produced trophy-class Shiras' bulls, and the unit's terrain and habitat are consistent with producing mature animals.
For context on expectations: a Shiras' moose is a once-in-a-lifetime caliber animal for most hunters. Colorado limits lifetime moose tags, meaning the draw is the hardest part of the entire hunt. Hunters who invest years of preference points to draw this unit are entering one of the most rewarding hunts available in the lower 48.
Herd Health & Population Trends
The harvest data itself provides indirect evidence of herd health. A unit sustaining 78–89% success rates across seven seasons, with hunter counts ranging from 13 to 41, suggests a moose population healthy enough to support consistent harvest without apparent decline in per-hunter success (aside from the modest dip associated with the larger 2025 allocation).
The growth in hunter numbers from 2019 to 2025 — from 13 hunters to 41 hunters — represents more than a tripling of the annual hunting pressure on the unit over that window. The fact that success rates remained strong through this period, with 2022 and 2023 both exceeding 85%, is a reasonable indicator of a robust underlying moose population capable of absorbing increased harvest.
No wildlife survey data (bull:cow ratios, population estimates) is included in the structured data for this unit. Hunters wanting deeper population trend analysis should request survey reports from Colorado Parks and Wildlife.
Access & Terrain
Unit 161 spans 261,039 total acres with 74% public land — a meaningful access figure that gives hunters genuine DIY options across the majority of the unit. The elevation band runs from 7,811 feet at the lower end to 12,102 feet at the upper reaches, covering a broad range of moose habitat from willow-choked creek bottoms and beaver pond complexes in the mid-elevations to subalpine terrain near the upper boundary.
The 23% wilderness designation within the unit adds an important layer to access planning. For nonresident hunters specifically, this matters: in Colorado, nonresidents are not legally required to hire a licensed guide to hunt wilderness areas — that requirement is specific to Wyoming. Colorado's wilderness areas are fully open to nonresident DIY hunting. That said, the wilderness terrain in Unit 161 demands appropriate backcountry preparation. Moose habitat in this elevation range is often found in dense riparian corridors, willow flats, and boggy creek drainages that are challenging on foot and even more challenging when packing out a bull.
For hunters willing to hunt the non-wilderness public land, the 74% overall public access figure means the unit is genuinely DIY-viable. Road-accessible hunting is feasible in portions of the unit, while hunters willing to push further into the wilderness portion will find reduced pressure and access to country that sees fewer boots.
Moose in this terrain type are classically found in willow and alder thickets adjacent to water — particularly in the mid-elevation transition zones between conifer forest and open meadow systems. The 7,811–12,102 foot elevation range encompasses exactly the habitat mix that supports resident moose populations in western Colorado.
HuntPilot Analysis: Is Unit 161 Worth Applying For?
For moose hunters: yes — with eyes open about the commitment required.
Unit 161's harvest data is among the most consistent in this article's dataset. A seven-year floor of 78% success, with multiple seasons exceeding 85%, is exceptional for any big game species. Add a strong regional trophy history and 74% public land access, and this unit checks the boxes that matter to serious moose applicants.
The honest counterpoint: Shiras' moose tags in Colorado are rare. This is not a unit hunters should expect to draw on their first or second application. Colorado uses a preference point system where points are consumed on a successful draw, meaning hunters who draw reset to zero afterward. The draw timeline for this unit — particularly for nonresidents — requires a multi-year point accumulation strategy, and applicants should review current draw data on HuntPilot's Colorado page at huntpilot.ai/states/co before committing to a point strategy.
Resident applicants face the same scarcity, though the tag fee difference is substantial (see How to Apply section). The key question for every applicant is whether they're prepared to commit the years necessary to build into this draw — because once the tag arrives, the hunt itself delivers.
How to Apply
For 2026, applications for Colorado Unit 161 moose are open under the following schedule:
- Application opens: March 1, 2026
- Application deadline: April 7, 2026
- Results posted: May 26, 2026
Nonresident costs (2026):
- Application fee: $11.49
- Tag fee: $2,824.00

Frequently Asked Questions
What is the harvest success rate in Colorado Unit 161 moose hunting?
Unit 161 has delivered exceptional harvest rates across every season in the available dataset. From 2019 through 2025, success ranged from a low of 78% (2025) to a high of 89% (2022), with four of seven seasons exceeding 84%. These figures represent unit totals across all tag types. By any measure, hunters who draw a tag in this unit have an outstanding probability of filling it.
What is the terrain like in Colorado Unit 161?
Unit 161 covers roughly 261,039 acres of western Colorado ranging from 7,811 to 12,102 feet in elevation. The terrain transitions from mid-elevation riparian corridors, willow flats, and beaver pond complexes — classic moose habitat — up through conifer forest and into subalpine terrain near the upper boundary. About 23% of the unit falls within designated wilderness, offering true backcountry hunting opportunities. The remaining public land (74% of total acreage) includes a mix of road-accessible areas and deeper terrain accessible on foot.
How big are the moose in Colorado Unit 161?
The counties overlapping Unit 161 carry a strong history of trophy-class Shiras' moose production. While specific scores and entry counts are not cited here, the area has produced trophy-class bulls over multiple decades and has the terrain and habitat to support mature animals. Hunters should note that trophy records are compiled at the county level and are shared across neighboring units — the trophy history reflects the broader region, not exclusively Unit 161. For trophy quality context, Shiras' moose are the smallest of North America's moose subspecies, but mature bulls in quality habitat are genuinely impressive animals and a legitimate lifetime achievement tag.
Is Colorado Unit 161 worth applying for?
Yes — for hunters serious about a Shiras' moose tag, Unit 161 is among the more compelling draws in Colorado. The combination of consistently high harvest success (78–89% across seven seasons), strong regional trophy history, and 74% public land access makes it a high-priority application for moose hunters. The realistic expectation is that drawing this tag requires a multi-year preference point investment. Hunters willing to make that commitment will find a unit that delivers when the tag finally arrives. For current draw odds and point requirements, visit huntpilot.ai/states/co.
Can nonresidents hunt Unit 161 moose without a guide?
Yes. Colorado does not require nonresident hunters to hire a licensed guide in wilderness areas — that requirement applies only in Wyoming. Nonresidents can plan a fully DIY moose hunt in Unit 161, including in the 23% of the unit designated as wilderness. That said, the backcountry terrain demands serious preparation: moose in this elevation range are found in dense, wet riparian habitat, and packing out a bull without logistical support is a significant physical undertaking. Many hunters choose to work with a guide or outfitter for practical reasons, but it is not legally required.
