Colorado Unit 66 Moose Hunting Guide

Colorado Unit 66 sits in the high country of the Gunnison Valley region, spanning elevations from 7,158 feet up to 14,274 feet across 575,448 acres of rugged terrain. For hunters chasing a moose tag in this part of the state, Unit 66 offers a legitimate opportunity — but one that comes with a demanding physical commitment and a draw process that requires patience. With 84% of the unit in public ownership and 18% designated wilderness, this is a unit where access is available to those willing to work for it.

Moose hunting in Colorado is a coveted pursuit precisely because tags are so limited statewide, and Unit 66 is no exception. The harvest numbers here are small by design — this is a low-volume, high-quality management approach that Colorado Parks and Wildlife applies to its moose herds. Understanding what the data actually shows, and what it doesn't, is critical before investing points and money into this pursuit.

HuntPilot Analysis: Is Unit 66 Worth Applying For?

The harvest data for Unit 66 moose tells a consistent story: this is a unit where drawn hunters kill their moose. Look at the recent stretch — in 2025, 10 hunters harvested 10 animals, a 100% success rate. In 2024, just 3 hunters harvested 5 moose (a 167% success figure, which reflects multiple harvests reported against a small hunter pool). Going back through 2023, 2022, 2021, 2020, and 2019, hunter numbers stayed in the low single digits every year, while harvest success consistently ran at 100% or higher. That is about as strong a harvest trend as exists in Colorado big game hunting, and it reflects both the skill of moose hunters (who tend to be experienced, patient applicants) and the relatively open terrain moose occupy in willow bottoms and high alpine drainages where they can be located and stalked methodically.

That said, hunters need to keep this in context. Moose hunts everywhere in Colorado run small hunter numbers because tags are tightly rationed by the state to protect herd health — Unit 66 is not unique in that regard. The takeaway isn't that moose hunting here is "easy," it's that once a hunter actually draws a tag, the odds of connecting are excellent if they put in the legwork.

Trophy potential is where Unit 66 requires a more measured take. The counties overlapping this unit carry a moderate history of trophy-class moose entries in the record books. That means hunters can realistically expect a mix of solid, mature bulls in the population, but this isn't a unit with a deep, sustained pedigree of exceptional bulls year after year. Hunters chasing a genuine trophy-of-a-lifetime animal should treat Unit 66 as a solid, credible option rather than a can't-miss destination — the moderate trophy history suggests some quality animals are present, but production isn't at the elite level seen in Colorado's top-tier moose units.

Access is a genuine strength here. With 84% public land, DIY hunters have room to roam without needing to negotiate private land access — a real advantage compared to many Colorado units where landownership fragments hunting opportunity. The 18% wilderness designation adds another wrinkle: a meaningful chunk of the unit sits in wilderness-designated terrain, which means no motorized or mechanized travel (including e-bikes) once inside those boundaries. Unlike Wyoming, Colorado does not require nonresidents to hire a guide to hunt wilderness areas, so DIY hunters are free to access that 18% on foot or horseback without a legal outfitter requirement.

Forum accounts from hunters who've spent time in Unit 66 reinforce a consistent theme: this is physically demanding country. One hunter who hunted the unit described it as having "very limited private and very physically demanding" terrain, and cautioned against spending a large point investment on it without understanding the physical toll. Bucks and bulls in this drainage system are often described as scattered — good animals show up in isolated basins while nearby, nearly identical-looking terrain can be empty. That's the nature of hunting big, wild country: the animals are there, but locating them requires time in the field, good glass work, and a willingness to cover ground at elevation.

Bottom line: Unit 66 is worth applying for if hunters are physically prepared for steep, high-elevation terrain and are seeking a moose hunt where drawn tags reliably convert into harvested animals. It's a strong choice for the DIY hunter who wants public land access and doesn't need guided infrastructure, but it should not be sold to prospective applicants as a top-shelf trophy unit — go in expecting a fair chance at a mature bull, not guaranteed record-book potential.

Herd Health & Harvest Trends

The multi-year harvest record for Unit 66 moose shows a herd that's being managed conservatively and successfully. Hunter numbers have hovered in the low single digits to low double digits across the 2019–2025 seasons (2 to 10 hunters per year), while harvest totals stayed proportionally strong or higher across that same window. That consistency — rather than any single standout year — is the most reliable signal available. A jump like 2025's 10-for-10 season shouldn't be read as evidence the unit suddenly got better; it's more likely a function of Colorado issuing more tags that year while maintaining the same high-success pattern the unit has shown for years.

For hunters evaluating whether this unit's moose population is stable, the takeaway from the available harvest data is that Colorado Parks and Wildlife has kept tag numbers conservative and success rates high across a seven-year window — a sign of a herd being managed for sustainability rather than being pushed hard by heavy hunter pressure.

Access & Terrain

Unit 66's elevation range — from 7,158 feet at the low end to 14,274 feet at its highest points — captures nearly the full spectrum of Colorado's high country, from valley floor sagebrush and riparian corridors up through subalpine timber and into true alpine terrain above treeline. Moose in this unit are most likely to be found working the willow-choked drainages and wet meadow systems that dot the mid-to-upper elevations, habitat that's well represented across the unit's 575,448 total acres.

With 84% of the unit in public ownership, access is not the limiting factor it is in many other Colorado units where checkerboarded private land blocks hunters from key drainages. The 18% wilderness component means hunters targeting those areas need to plan for foot or horseback access only — no vehicles, no game carts with wheels, no e-bikes. Given the physical difficulty repeatedly noted by hunters who've spent time here, a horseback or pack-supported approach for wilderness portions of the unit is worth serious consideration, especially for older hunters or those without recent experience packing out large animals from high-elevation, roadless terrain.

Forum commentary on this unit consistently underscores the physical demand: hunters describe it as rugged, with big country to cover and no guarantee that any single basin will hold animals on a given day. That matches what would be expected from a unit spanning this much elevation and terrain diversity — success tends to go to hunters willing to scout hard, glass patiently, and adjust to where moose are actually concentrated in a given season rather than where they were the year before.

Trophy Quality

Trophy records tied to the counties overlapping Unit 66 reflect a moderate history of quality moose production. This isn't a unit defined by a strong, decades-deep run of exceptional bulls, but it also isn't a unit lacking any trophy pedigree — moderate history suggests mature, respectable bulls do come out of this country with some regularity. Hunters should calibrate their expectations accordingly: a good bull is realistic, an exceptional or record-class animal is possible but not something to bank a hunt plan around.

It's worth remembering that trophy records are logged at the county level, and the counties overlapping Unit 66 also overlap neighboring units — meaning any trophy animals attributed to this geography could have been taken anywhere within that shared county footprint, not necessarily inside Unit 66's specific boundaries. That nuance matters when comparing unit-to-unit trophy reputations across this region of the Gunnison Valley.

How to Apply

Note that the license fee is a required purchase before an application can even be submitted — this is in addition to the application fee, and separate from the tag fee that's only paid if a hunter actually draws.

Demand for Colorado moose tags is heavily contested across nearly every unit in the state, Unit 66 included, and residency-based point requirements can differ significantly year to year. Rather than guessing at odds, hunters should check the HuntPilot Colorado state page (/states/co) or Unit 66's dedicated HuntPilot page for the most current draw odds and point data before building an application strategy.

Frequently Asked Questions

What is the terrain like in Colorado Unit 66? Unit 66 covers a massive elevation gradient, from 7,158 feet up to 14,274 feet, encompassing everything from valley-bottom sagebrush and riparian corridors to high alpine basins above treeline. Hunters who've spent time in the unit describe it as physically demanding, with moose and deer scattered across isolated basins that can look identical from a distance but hold vastly different numbers of animals. With 84% public land, access is broadly available, though the 18% wilderness portion requires foot or horseback travel only.

What is harvest success like for moose hunters in Unit 66? Harvest success has been strong and consistent. Across the 2019 through 2025 seasons, success rates ran at or above 100% every single year, including a 100% rate in 2025 (10 hunters, 10 harvested) and rates exceeding 100% in several earlier years due to multiple harvests reported against very small hunter pools. This reflects the nature of Colorado's tightly-rationed moose tags — low hunter numbers combined with dedicated, experienced applicants tends to produce high success once a tag is drawn.

How big are the moose in Unit 66? Trophy records tied to the counties overlapping Unit 66 show a moderate history of trophy-class moose. That means mature bulls are present and quality animals have come from this geography, but it's not among Colorado's elite trophy-producing areas. Hunters should expect a realistic shot at a solid, mature bull rather than planning around a guaranteed record-class trophy.

Is Unit 66 worth applying for as a moose hunter? Yes, with realistic expectations. The unit combines strong public land access (84%), consistently high harvest success once drawn, and moderate trophy potential. It's best suited to hunters who are physically prepared for steep, high-elevation terrain and want a DIY-friendly unit without the access headaches of heavily privatized units elsewhere in Colorado. It is not the unit to chase if the sole goal is a record-book bull.

Do nonresidents need a guide to hunt the wilderness portions of Unit 66? No. Colorado does not require nonresidents to hire a licensed outfitter to hunt wilderness areas, unlike some other western states. Nonresident hunters can access the unit's 18% wilderness designation on their own, on foot or horseback, keeping in mind that no motorized or mechanized equipment — including game carts with wheels or e-bikes — is permitted inside wilderness boundaries.
