Colorado Unit 43 Moose Hunting Guide

Colorado Unit 43 sits high in the northern part of the state, ranging from 5,650 feet at its lowest reaches up to 14,042 feet along its highest peaks. This dramatic elevation spread, combined with 336,309 total acres and 79% public land, makes Unit 43 one of the more accessible moose units in Colorado for hunters willing to put in the legwork at altitude. With 27% of the unit designated wilderness, hunters here have a genuine mix of road-adjacent country and true backcountry to work with.

Moose hunting in Colorado is a limited-quota proposition everywhere in the state, and Unit 43 is no exception — there is no general season here. Every moose hunt in this unit runs through the draw, covering both antlered and either-sex opportunities depending on the specific hunt code. For hunters who eventually draw a tag, Unit 43 offers a legitimate shot at a mature Shiras moose in rugged, scenic terrain with strong public access.

This article breaks down what the harvest data, trophy history, and terrain in Unit 43 actually tell hunters — and whether it's worth investing points toward a tag here.

HuntPilot Analysis: Is Unit 43 Worth Applying For?

Based on the data available through HuntPilot, Unit 43 is a solid option for hunters targeting Colorado moose, particularly those who value public land access and don't mind rugged, high-elevation country. The unit's 79% public land ownership means DIY hunters have room to operate without needing to negotiate private land access, and the 27% wilderness component offers a true backcountry option for hunters looking to get away from roads.

The harvest numbers tell a clear story: this is an extremely low-volume, high-success unit. In 2025, six hunters harvested five animals for an 83% success rate. Every prior year on record shows either 100% success or very close to it — 2024 saw three hunters and three harvests, 2023 and 2022 each saw two hunters with two harvests, and 2021 had a single hunter who tagged out. Across five years of data, no season has dropped below an 83% success rate, and most years show perfect harvest rates.

That said, hunters need to interpret these numbers correctly. This isn't a unit that produces dozens of tags — it's a unit where a small handful of hunters draw each year, and nearly all of them fill their tag. High success rates on a hunt with only one to six hunters afield reflect low hunter density and good moose density more than anything else. It also means there's very little year-to-year data to smooth out variance — a single unsuccessful hunter in 2025 moved the success rate from 100% to 83%.

Trophy potential in the surrounding counties is best described as moderate. The record-book history tied to the counties overlapping Unit 43 shows some trophy production over time, but not at the elite, consistent level seen in Colorado's top-tier moose country. Hunters drawing a tag here should expect a legitimate, mature Shiras bull is possible, but shouldn't count on this unit alone to produce a record-class animal. For most hunters, especially those drawing a once-in-a-lifetime moose tag, the experience and quality of a mature bull in this terrain will be the primary reward — trophy scoring should be treated as a bonus, not the expectation.

Given the near-perfect harvest success, strong public land percentage, and legitimate wilderness backcountry option, Unit 43 is worth serious consideration for any hunter building points toward Colorado moose. It won't be the fastest draw, but the payoff once a tag is in hand is well-supported by the data.

Harvest Success Rates

The harvest data for Unit 43 spans five recent years and shows consistently high success:

• 2025: 6 hunters, 5 harvested — 83% success
• 2024: 3 hunters, 3 harvested — 100% success
• 2023: 2 hunters, 2 harvested — 100% success
• 2022: 2 hunters, 2 harvested — 100% success
• 2021: 1 hunter, 1 harvested — 100% success

These figures represent unit-wide totals across all moose hunt codes, covering both antlered and either-sex tags issued through the draw. The pattern here is unmistakable — nearly every hunter who draws a Unit 43 moose tag goes home with an animal. This is common in Colorado moose units generally, since moose don't flee hunting pressure the way elk or deer do, and low tag numbers mean minimal competition among hunters in the field.

Hunters should still treat these numbers with appropriate context. A sample size of one to six hunters per year is small, and a single unfilled tag swings the success percentage significantly, as seen in the 2025 data. The multi-year trend, however, is the more reliable signal: this unit has produced high success for at least five consecutive years running.

Trophy Quality

Trophy potential in Unit 43 is best categorized as moderate. The counties overlapping this unit carry some history of trophy-class moose entries in the record books, but production has not been prolific or consistent enough to call this an elite trophy destination. Hunters should go into a Unit 43 moose hunt expecting a mature, representative Shiras bull to be a realistic and worthy goal, while understanding that a record-book animal would be a genuine outlier rather than a typical outcome.

For context, Colorado's moose herds statewide have matured significantly since the species was reintroduced decades ago, and bull quality has improved as herds have aged and stabilized. Unit 43's moderate trophy history fits within that broader pattern — good, mature bulls exist, but this isn't one of the handful of units in the state known for consistently producing top-end record-book animals.

Access & Terrain

Unit 43 spans an enormous elevation gradient — from 5,650 feet up to 14,042 feet — which gives hunters access to nearly every terrain type found in Colorado's high country: sagebrush foothills and riparian drainages at the lower elevations, dense timber and willow-choked creek bottoms in the mid-elevations (prime moose habitat), and alpine basins and rocky peaks up top.

With 336,309 total acres and 79% public land, the large majority of this unit is open to hunters without needing private land permission, making Unit 43 genuinely DIY-friendly for hunters willing to plan around public access points. The 27% wilderness designation means over a quarter of the unit requires foot or stock travel — no motorized access — which pushes hunting pressure down in those areas and rewards hunters willing to get deeper into the backcountry.

Moose are creatures of willow bottoms, beaver ponds, and thick riparian corridors, so hunters should focus scouting efforts on drainages holding this kind of habitat, particularly at mid-to-high elevations where forage and cover overlap. Given the wilderness percentage and the unit's high-elevation ceiling, hunters should be prepared for demanding physical terrain, particularly if targeting the wilderness portion of the unit. Hunters can use HuntPilot's mapping tools to overlay public land boundaries, wilderness boundaries, and elevation data directly onto Unit 43 to identify drainages and glassing points worth investigating before the season.

How to Apply

Colorado moose tags are allocated entirely through the state's limited-quota draw system — there is no general season or over-the-counter option for moose anywhere in Colorado, including Unit 43. Every hunter, resident or nonresident, must apply through the draw to hunt moose in this unit.

Colorado's draw system for moose uses a preference point structure, meaning hunters accumulate points in years they apply but don't draw, and higher point totals improve position in the draw over time. Residents and nonresidents apply in separate pools, and nonresidents typically face longer point-building timelines than residents for the same units. Because moose tags are extremely limited statewide and demand is high, most hunters — resident or nonresident — should expect to spend multiple years accumulating points before drawing a Unit 43 tag.

Hunters should also note that a successful draw consumes accumulated preference points, meaning point totals reset after a tag is drawn. Anyone planning a repeat moose hunt in Colorado should plan on rebuilding points from scratch after their first successful draw.

Application structure, deadlines, and fees change from year to year, so rather than citing specifics here, hunters should check HuntPilot's Colorado state page at /states/CO for the current application windows, fee schedules, and point requirements, and the Unit 43 page directly for the latest draw odds and application data.

Frequently Asked Questions

Is Colorado Unit 43 worth applying for? Based on the available harvest data, yes — Unit 43 shows consistently high success rates (83-100% across the last five years) for hunters who draw a moose tag, strong public land access at 79%, and a real wilderness option for hunters seeking backcountry solitude. Trophy potential is moderate rather than exceptional, so hunters should apply here expecting a quality, mature bull rather than counting on a record-book animal.

What is harvest success like in Unit 43 for moose? Extremely high. Every year from 2021 through 2024 posted 100% harvest success, and 2025 came in at 83% (5 of 6 hunters). These numbers reflect low hunter volume rather than easy hunting conditions — moose tags here are scarce, and the hunters who draw them tend to fill their tags at a very high rate.

What is the terrain like in Unit 43? Unit 43 covers a massive elevation range from 5,650 to 14,042 feet, offering everything from lower-elevation sagebrush and riparian country to dense mid-elevation timber and willow bottoms (prime moose habitat) up to alpine terrain near the peaks. With 79% public land and 27% wilderness, hunters have substantial room to roam, though the wilderness portions require foot or stock access only and demand serious physical preparation.

How big are the moose in Unit 43? Trophy records tied to the counties overlapping Unit 43 show a moderate history of trophy-class entries — meaning quality, mature bulls are attainable, but this isn't one of Colorado's top producers of record-book animals. Most hunters should set expectations around a solid, mature Shiras bull rather than a record-book trophy.

Do I need a guide to hunt the wilderness portion of Unit 43? No. Colorado does not require nonresidents to hire a guide or outfitter to hunt wilderness areas, unlike some neighboring states. Both residents and nonresidents can hunt the wilderness 27% of Unit 43 unguided, though the terrain and lack of motorized access make careful planning and physical conditioning essential.
