Colorado Unit 4 Moose Hunting Guide
Introduction
Colorado Unit 4 moose hunting sits in the northwestern corner of the state, occupying roughly 299,151 acres of mixed terrain ranging from approximately 6,189 to 10,853 feet in elevation. This dramatic elevation range means moose hunters encounter everything from riparian willow corridors and sagebrush flats at lower elevations to dense spruce-fir timber and subalpine meadows near the upper reaches of the unit. For any hunter seriously researching a Colorado moose draw, Unit 4 deserves a close look — moose tags in Colorado are among the most coveted big-game permits in the West, issued in extremely limited numbers, and Unit 4 has a documented harvest history worth examining.
Colorado's moose population has expanded significantly since reintroduction efforts began in the late 1970s, and the northwest corner of the state — including Unit 4's range — has been among the most productive areas for the species. With roughly 48% of the unit in public ownership, DIY hunters do have access to meaningful ground, though nearly half the unit is private land. Understanding the lay of the land before committing points and application fees to this draw is essential, and the data compiled by HuntPilot provides a solid foundation for that research.
Moose hunting in Colorado is a point-intensive, once-in-a-career pursuit for most hunters. Tags are extraordinarily limited, and most hunters who successfully draw have accumulated preference points over many years. The 2025 harvest data for Unit 4 paints a compelling picture of what successful hunters can expect when they do punch their ticket.
Harvest Success Rates
The 2025 harvest data for Colorado Unit 4 moose is about as strong as it gets for any big-game hunt anywhere in the West. In 2025, 30 hunters pursued moose in the unit and 29 of them filled their tags — a 97% success rate. That is not a misprint. For context, a 97% harvest rate on a species as challenging to locate and pack out as moose reflects a combination of a healthy, accessible population and hunters who had done their homework before the season opened.
For hunters weighing multiple Colorado moose units against each other, success rates in the high-90s are a meaningful indicator that animals are present in the unit in harvestable numbers and that hunters are consistently able to close the deal. It also suggests that the terrain, while rugged in places given the 6,189–10,853 foot elevation spread, does not present the kind of access obstacles that suppress success rates in more remote Colorado moose units.
One year of data does not define a unit, but 97% success on a 30-hunter sample is a substantial and credible data point. Hunters researching this unit should note it accordingly.
Trophy Quality
The counties overlapping Colorado Unit 4 carry a moderate history of trophy-class moose production. This is not a unit with an elite, decades-long record of exceptional bulls stacking up in the trophy records — but it is not a blank slate either. Hunters who have tagged out in this area over the years have produced animals worth noting, and the history suggests that mature bulls with genuine trophy potential are present in the unit.
For moose hunting, "moderate trophy potential" is still significant context. Shiras' moose are the smallest of the three North American moose subspecies, and the bar for a genuine trophy-class Shiras' bull is meaningful. The unit's elevation range and habitat diversity — particularly the lower-elevation willow and riparian corridors that moose depend on for summer feeding and the higher timbered terrain they use as cover — create the conditions where bulls can reach maturity undisturbed by the hunting pressure common in more accessible areas.
Hunters targeting Unit 4 should not expect a guaranteed record-book outcome, but the trophy history suggests that patient hunters willing to put in glassing time have a realistic chance at a quality bull. Given the near-universal harvest success data, the odds of killing a moose here are excellent — the grade of that animal will depend heavily on scouting, timing, and the individual hunter's selectivity.
Herd Health & Population Trends
Structured wildlife survey data for Unit 4 moose is not included in the available data for this article. Hunters seeking current bull-to-cow ratios, calf recruitment data, or population trend information for this specific unit should contact Colorado Parks and Wildlife's northwest region directly and review the agency's most recent moose herd management plan for the area.
What the 2025 harvest data does indirectly confirm is that the moose population in Unit 4 is supporting a meaningful number of tags with an extremely high success rate. A unit-level 97% harvest rate would be impossible to sustain if the underlying population was stressed or declining. The harvest data is the most current and direct proxy available for herd health in this unit, and it reflects positively on population status.
Access & Terrain
Colorado Unit 4 spans 299,151 acres with 48% in public ownership — approximately 143,000 acres of publicly accessible ground. That is a workable amount of terrain for DIY hunters, but it requires advance mapping and planning since roughly 52% of the unit is private. Hunters who do not secure landowner access or carefully identify public land boundaries before arriving will find themselves limited in their options, particularly in areas where private and public ground is interspersed.
The elevation range — 6,189 feet at the lowest to 10,853 feet at the top — creates a vertical spread of over 4,600 feet within a single unit. That range translates to dramatically different terrain and vegetation types across the unit. Lower elevations feature the willow-choked creek bottoms and riparian corridors that moose depend on heavily. Mid-elevations bring mixed terrain transitioning into aspen parks and conifer timber. The upper reaches push into subalpine spruce-fir forest and open tundra country near the top of the elevation band.
There is no designated wilderness within Unit 4. This is significant for nonresident hunters — in Colorado (unlike Wyoming), nonresidents are not required to hire a licensed guide to hunt wilderness areas, but the absence of wilderness in this unit means the question is moot. Hunters can access all public ground in Unit 4 as DIY hunters regardless of residency.
The terrain is demanding enough that moose hunters should be physically prepared for off-trail travel through timber and wetland vegetation. Moose habitat in particular tends toward thick, wet, brushy terrain that is slow going on foot. Pack-out logistics for a mature bull moose — which can weigh 600–900 pounds on the hoof — should be planned before the hunt, not after. Horses or a pack-in setup are worth serious consideration, especially for hunters planning to access more remote corners of the public land.
HuntPilot Analysis
Is Colorado Unit 4 worth applying for moose?
Yes — with the clear-eyed understanding that drawing a Colorado moose tag of any kind requires a substantial point investment. Unit 4 delivers on the two metrics that matter most for any limited-entry big-game hunt: high harvest success (97% in 2025) and documented trophy potential. The terrain is demanding but navigable, the unit has meaningful DIY-accessible public land at 48%, and there is no wilderness complication to contend with.
The honest caveat is that moose tags in Colorado are among the rarest big-game permits in the state. Hunters who have not already been building preference points should start immediately if moose is a genuine target species. Hunters with substantial point banks should examine Unit 4's draw competitiveness carefully against comparable northwest Colorado units — a task best done with current draw data from the HuntPilot unit page at /states/co.
For nonresidents, the all-in cost of a Colorado moose tag is significant. The 2026 tag fee for nonresidents is $2,824, plus a required license fee of $117.62, an application fee of $11.49, and a point fee of $100. Total nonresident investment if drawn: approximately $3,053 in licensing and tag fees alone, before any travel, gear, or meat-care costs. For residents, the draw cost structure is more accessible: $386 tag fee, $53.19 license fee, $9 application fee, and a $50 point fee.
This is not a casual application decision for nonresidents. But for hunters who are serious about Colorado moose and have the point foundation to compete, Unit 4's harvest data and trophy history make it one of the more compelling units to put on the application list.
How to Apply
Colorado moose tags are distributed through the state's preference point draw system. Both residents and nonresidents apply through the same annual draw cycle with the same deadline.
For 2026, the application window opens March 1, 2026, and closes April 7, 2026. Results are posted May 26, 2026. Do not miss the April 7 deadline — there is no late application option for limited-entry draws in Colorado.
2026 Nonresident Moose Application Costs:
- Application fee: $11.49
- Tag fee (if drawn): $2,824.00
- License fee (required to apply): $117.62
- Preference point fee: $100.00
2026 Resident Moose Application Costs:
- Application fee: $8.93
- Tag fee (if drawn): $386.00

A critical detail that catches first-time Colorado moose applicants off guard: hunters must purchase the required base license ($117.62 nonresident / $53.19 resident) before or during the application process. This license fee is required to apply — it is not optional and cannot be skipped. Failure to hold the qualifying license will disqualify the application.

Frequently Asked Questions
What is the terrain like in Colorado Unit 4 for moose hunting?
Unit 4 spans roughly 299,151 acres across an elevation range of 6,189 to 10,853 feet. Moose hunters will encounter riparian willow corridors and creek bottoms at lower elevations — classic moose habitat — transitioning through aspen and mixed conifer terrain in the mid-elevations, and into subalpine spruce-fir timber near the top of the unit. The terrain moose favor is typically wet, brushy, and demanding to move through. Hunters should be prepared for significant off-trail travel and plan pack-out logistics for a large animal well before the hunt. There is no designated wilderness in Unit 4.
What is the harvest success rate for moose in Colorado Unit 4?
In 2025, Unit 4 recorded a 97% moose harvest success rate — 29 of 30 hunters filled their tags. This is an exceptionally high success rate for any big-game species and reflects a combination of a healthy moose population and accessible habitat. Hunters who draw this tag have historically had excellent odds of punching it.
How big are the moose in Colorado Unit 4?
The counties overlapping Unit 4 carry a moderate history of trophy-class Shiras' moose production. Trophy-class animals have been taken from this area, though it is not among the elite-tier units known for consistently producing record-book bulls. Hunters targeting quality mature bulls should plan on doing significant pre-season scouting to identify specific animals before the season opens. Given the near-universal harvest success rate, tag-filling odds are high — individual bull quality will depend on scouting effort and hunter selectivity.
Is Colorado Unit 4 worth applying for moose as a nonresident?
For nonresidents serious about Colorado moose hunting and willing to make the financial and point investment, Unit 4 is a legitimate target. The 97% harvest success rate and moderate trophy history make it a competitive choice. The total nonresident cost if drawn runs over $3,000 in tags and fees alone, and drawing any Colorado moose tag requires a significant preference point investment. Hunters should check current draw competitiveness data on the HuntPilot unit page at /states/co before committing their point bank.
How much does it cost to apply for a Colorado Unit 4 moose tag?
For 2026, nonresidents pay an $11.49 application fee, a $100 point fee, and a $117.62 base license fee (required to apply) — approximately $229 total to apply. If drawn, the nonresident tag fee is $2,824. Residents pay an $8.93 application fee, a $50 point fee, and a $53.19 base license fee, with a $386 tag fee if drawn. The base license is required to apply and is separate from the application fee — this catches many first-time applicants off guard.
