Colorado Unit 66 Moose Hunting Guide
Colorado Unit 66 sits in the rugged southwestern corner of the state, spanning 575,448 acres of some of the most dramatic terrain in the Rocky Mountain West. Elevations range from 7,158 feet in the valley bottoms to 14,274 feet at the highest peaks — a vertical spread that defines the character of this hunt and the effort required to pursue moose here. With 84% public land, access is genuinely strong for DIY hunters, and the unit's 18% wilderness designation adds a layer of solitude to the deeper reaches. This is not a unit for the casual applicant. Colorado Unit 66 moose hunting demands physical fitness, serious logistical planning, and a willingness to commit to one of the most demanding landscapes in the state.
Moose hunting in Colorado is among the most coveted big game experiences in the West, and Unit 66 is one of the relatively limited options available to both residents and nonresidents. Tag allocations are intentionally restricted to protect a population that is still developing compared to historic strongholds farther north. That scarcity, combined with the unit's terrain and public land base, makes Unit 66 a serious consideration for moose applicants who have been accumulating preference points.
Harvest Success Rates
The harvest data for Unit 66 moose is striking — and unusual enough to warrant close reading before drawing conclusions.
From 2019 through 2025, the unit consistently showed success rates above 100%, which reflects a unit structure where the number of animals harvested can exceed the number of hunters counted in a given reporting period. In 2025, 10 hunters produced 10 harvested animals, a clean 100% success rate. In prior years, the numbers were even more pronounced: 2024 saw 3 hunters and 5 animals harvested (167% success), 2023 showed 4 hunters and 5 harvested (125%), 2022 mirrored 2023 exactly at 4 hunters and 125% success, and 2021 recorded 3 hunters with 5 harvested at 167%. Going back further, 2020 produced a 250% success rate (2 hunters, 5 harvested) and 2019 showed 200% (2 hunters, 4 harvested).
What these numbers tell experienced hunters: the tag pool is extremely small, and the per-hunter success across all permit types — which may include antlerless permits layered on top of bull permits — is consistently high. The practical takeaway is that hunters who draw a tag in Unit 66 have an exceptional likelihood of filling it. Multi-year data from 2019 through 2025 shows not a single year fell below 100% success. That consistency is rare in any big game context and reflects a combination of quality habitat, relatively low hunting pressure, and guides to the unit's terrain who know where animals concentrate.
Hunters should note that the raw hunter counts are small — often in the single digits — which means these percentages carry some statistical volatility. But the directional signal is clear: if you draw a tag here, the odds strongly favor going home with an animal.
Trophy Quality
Based on the trophy history associated with the counties overlapping Unit 66, this area carries moderate trophy potential for moose. Trophy-class animals have been taken from this region, but they are not prolific, and hunters should set expectations accordingly. Colorado's Shiras' moose — the subspecies found throughout the state — are the smallest of North American moose subspecies, and even exceptional specimens are modest compared to Alaskan or Canadian animals. Within that context, Unit 66 has produced its share of creditable bulls over the years, but hunters entering this draw purely for record-book aspirations should understand that trophy production here is not at the top of the state's moose units.
The more compelling case for this unit is the combination of high harvest success, strong public access, and a legitimate wilderness experience in demanding terrain — not necessarily a guaranteed shot at an exceptional bull.
Herd Health & Population Trends
Hard wildlife survey data is not available in the structured data for Unit 66. What the harvest record suggests is a stable, huntable population with consistent harvest year over year. The extremely small tag numbers indicate that Colorado Parks & Wildlife is managing this population conservatively — a common and appropriate approach for Shiras' moose throughout the southern Rockies, where populations are thinner than in core moose habitat farther north.
The unit's elevation range, from valley bottoms into alpine terrain above 14,000 feet, provides diverse seasonal habitat. Moose in high-elevation Colorado units typically use willow-choked creek drainages and beaver pond complexes at lower and mid-elevations, with bulls moving into subalpine and lower alpine zones during the summer months. The vertical range within Unit 66 means animals can be found at drastically different elevations depending on season and conditions.
Access & Terrain
Unit 66's terrain is the defining challenge of this hunt. At 575,448 total acres with an 84% public land composition, hunters have genuine freedom of movement across the landscape. That's a significant advantage over many Colorado units where private land creates access puzzles and blocks critical habitat.
The 18% wilderness designation — representing roughly 103,000 acres — means a substantial portion of the unit is roadless country. In Colorado, nonresidents are not legally required to hire a guide to hunt wilderness, unlike Wyoming. DIY hunters can access wilderness portions of Unit 66 without outfitter support. That said, the physical demands of this terrain are serious: relief from valley floors to summits exceeds 7,000 vertical feet, and the wilderness sections will require pack-in logistics — horses or heavy packs — to access efficiently.
Forum discussion around this unit consistently describes it as physically demanding country. Hunters who have spent time here emphasize that it is genuinely rugged, with large basins of similar-looking terrain where glassing and covering ground are the primary tactics. The high-country sections reward hunters who are willing to put in the miles and gain the elevation.
For moose specifically, hunters should focus their pre-season research on drainage bottoms, riparian corridors, and willow flats at appropriate elevations. Moose are generally not alpine animals in the same way elk can be — they tend to concentrate in areas with water, dense browse, and thermal cover. Within Unit 66's large footprint, identifying those specific habitat pockets is the primary scouting challenge.
Drop camps with pack string support are a practical option for accessing the deepest portions of the unit, particularly the wilderness zones. Road-accessible areas around the unit's perimeter offer more logistically straightforward options but typically come with higher human activity.
HuntPilot Analysis
Is Unit 66 worth applying for moose? For hunters who have been building preference points toward a moose tag in Colorado, this unit deserves serious consideration — but with clear-eyed expectations.
The case for this unit is strong on several dimensions. The 84% public land base is excellent, giving DIY hunters legitimate access to most of the unit without navigating private land obstacles. The harvest success record from 2019–2025 is among the most consistent in the state: zero years below 100% across the entire data window. Hunters who draw appear to be getting close encounters with animals and filling tags at an exceptional rate. The wilderness character of the deeper sections adds a quality to the experience that is genuinely rare.
The considerations working against it are also worth naming. The trophy ceiling here is moderate rather than exceptional based on the available history. This is Shiras' moose country in southern Colorado — a legitimate and rewarding hunt, but not the same caliber of animal as northern species. The terrain is brutally demanding, and hunters who are not in strong physical condition will find the high-elevation, high-relief country punishing. The tag numbers are very small, reflecting a conservatively managed population.
The honest verdict: Unit 66 is a legitimate moose draw worth targeting for hunters who prioritize high harvest probability, meaningful public land access, and a true wilderness experience in demanding Colorado terrain. It is not the right draw for hunters who are primarily chasing record-book bull size. For Colorado moose applicants with a competitive preference point stack, this unit belongs on the short list.

2026 Fee Summary:
| Fee Type | Resident | Nonresident | |---|---|---| | Application fee | $8.93 | $11.49 | | License fee (required to apply) | $53.19 | $117.62 | | Tag fee (if drawn) | $386.00 | $2,824.00 | | Preference point fee (if not drawn) | $50.00 | $100.00 |
Note that Colorado requires hunters to purchase a valid hunting license before applying for a draw tag — the license fee is not optional and must be paid regardless of whether you are ultimately drawn. The nonresident tag fee of $2,824 applies only upon drawing a tag.
Hunters who are not drawn will have the option to purchase a preference point for $50 (resident) or $100 (nonresident) to advance their position for future draws. Colorado operates a preference point system for moose, meaning hunters with the most points are drawn first — making point accumulation a meaningful long-term strategy for this species.
Dates and fees are subject to change. Always verify current application details at the Colorado Parks & Wildlife website before applying.
Frequently Asked Questions
What is the terrain like in Colorado Unit 66 for moose?
Unit 66 spans an elevation range of 7,158 to 14,274 feet across 575,448 acres, making it one of the more vertically dramatic units in Colorado. Hunters should expect a mix of river-bottom riparian habitat, mid-elevation willow flats and beaver complexes, dense subalpine timber, and open high-country basins. Moose tend to concentrate in drainages and lower-elevation willow corridors rather than the alpine terrain. Roughly 18% of the unit is designated wilderness, requiring pack-in logistics for the deepest sections. The unit is described by hunters who have been there as genuinely demanding — large, physically rugged, and rewarding for those who are prepared.
What is the harvest success rate for moose in Unit 66?
Harvest success in Unit 66 has been exceptional from 2019 through 2025, consistently at or above 100% in every recorded year. In 2025, all 10 hunters who held tags harvested animals. In prior years, including 2021 and 2024, fewer than 5 hunters apiece produced 5 or more harvested animals due to the structure of permit types issued. This is one of the more reliable harvest records among Colorado moose units, though hunters should be aware that the small tag numbers create some statistical variability year to year.
How big are the moose in Colorado Unit 66?
Unit 66 holds Shiras' moose, the smallest subspecies of North American moose. The counties overlapping this unit have a moderate history of trophy production, meaning creditable bulls have been taken here over the years, but this is not considered an elite trophy-producing unit by Colorado standards. Hunters should come with realistic expectations for Shiras' moose in general — these are impressive animals, but their antler size is modest compared to subspecies found farther north. The primary appeal of this unit is its high harvest probability and quality public land access, not its record-book trophy ceiling.
Is Colorado Unit 66 worth applying for moose?
For hunters with a meaningful preference point accumulation, Unit 66 is worth serious consideration. The 84% public land base provides excellent DIY access, harvest success rates have been consistently high for the full 2019–2025 data window, and the wilderness character of the unit offers a quality hunting experience. The unit is not ideal for hunters prioritizing maximum trophy size, but for applicants who want a high-probability moose tag in challenging, rewarding Colorado terrain, it competes well against other options in the state. Check HuntPilot's Colorado page for current draw odds before committing points.
Do nonresidents need a guide to hunt Unit 66 moose?
No. Colorado does not require nonresident hunters to hire a licensed guide or outfitter, even in the unit's wilderness areas. DIY nonresident moose hunters can legally access all of Unit 66 independently. That said, the wilderness portions of the unit are logistically demanding, and many hunters choose to use a drop camp or pack string for accessing the deepest terrain — not for legal reasons, but for practical ones. Hiring support for a wilderness moose hunt in this type of country is a worthwhile investment in efficiency and safety, but it is entirely optional.
