Colorado Unit 15 Moose Hunting Guide

Colorado Unit 15 sits in a stretch of high country ranging from 6,658 to 10,801 feet in elevation, spanning nearly 315,000 acres of mixed terrain in the central part of the state. For hunters chasing a moose tag, Unit 15 offers a genuine backcountry experience with 70% public land and 14% wilderness, giving DIY hunters real room to operate without leaning entirely on private ground. This article breaks down what the data actually shows about Unit 15 moose hunting — harvest trends, application costs, and what hunters should realistically expect if they draw a tag here.

Moose hunting in Colorado is a unique animal compared to elk or deer. Tags are scarce, the species is relatively new to the state's hunting program (moose were introduced in the 1970s and 1980s), and demand for tags in every unit — including Unit 15 — consistently outstrips supply. Understanding the specific numbers behind Unit 15 helps hunters decide whether to spend points here or look elsewhere.

Harvest Success Rates

Unit 15's moose harvest numbers are about as strong as it gets in Colorado, and the data across the past seven years backs that up. In 2025, 18 hunters harvested 18 animals — a 100% success rate. In 2024, 6 hunters harvested 7 animals (117%, reflecting either multiple tags per hunter or leftover cow/calf combination tags counted in the total). Going back further: 2023 saw 7 hunters harvest 7 animals (100%), 2022 posted 6 harvests from 7 hunters (86%), 2021 produced 5 harvests from just 3 hunters (167%), and both 2020 and 2019 hit 100% success with 7-for-7 and 6-for-6 tallies respectively.

This is a remarkably consistent trend. Across seven seasons of recorded data, Unit 15 has never dropped below 86% unit-wide success, and most years sit at or above 100%. For context, moose hunting success rates in the West are generally elevated compared to elk or deer because tags are so limited and hunters who draw tend to be well-prepared, often having waited years to get the opportunity. Unit 15 fits that pattern well. If a hunter draws a tag here, the harvest data strongly suggests they will fill it.

Trophy Quality

Trophy data for Unit 15 moose is limited, but the counties overlapping this unit carry a moderate history of trophy-class entries in the record books. That places Unit 15 in a middle tier — not a unit with a deep, decades-long reputation for producing top-end bulls, but one that has produced trophy-quality animals over time. Hunters should treat this as a realistic expectation-setter: Unit 15 is a legitimate place to take a mature bull moose, but it is not positioned among Colorado's elite trophy units based on the available record history.

Given that record-book entries are logged at the county level and shared across all units within those counties, hunters should view this trophy history as regional rather than unit-exclusive — neighboring units drawing from the same counties share in that same moderate trophy pedigree.

Herd Health & Population Trends

While detailed bull-to-cow survey ratios aren't available in the data reviewed here, the harvest numbers themselves offer an indirect window into herd health. A unit sustaining 100%+ success rates across nearly every season from 2019 through 2025 — including a jump to 18 hunters and 18 harvests in 2025 — suggests a stable, huntable moose population with enough mature animals to support consistent tag fulfillment. The increase in hunter numbers in 2025 (18, up from single digits in prior years) likely reflects an increase in tags allocated for that season, which is itself a signal that Colorado Parks and Wildlife views the Unit 15 moose herd as healthy enough to support additional harvest pressure.

Access & Terrain

Unit 15 offers 70% public land, which is a strong number for DIY-minded hunters and means the majority of the unit is open to hunt without needing private land access or landowner permission. With 14% of the unit designated wilderness, hunters have a meaningful chunk of country where mechanized access is restricted, rewarding those willing to hike deeper into the backcountry away from roads.

Elevation in the unit ranges from 6,658 feet up to 10,801 feet, which covers everything from lower valley terrain and riparian corridors — prime moose habitat — up into higher alpine basins. Moose in Colorado tend to concentrate around willow-lined drainages, beaver ponds, and mixed timber where aspen and conifer stands meet, and Unit 15's elevation range supports that kind of habitat diversity. Hunters reporting on Unit 15 have described a mix of terrain types, from more open sagebrush-and-timber transition zones to higher-elevation pockets, though hunters should not expect uniformly easy access — remote pockets of the unit will require serious hiking effort, especially in the wilderness-designated portions.

Because 30% of the unit remains private land, hunters should scout carefully using mapping tools to identify property boundaries before committing to an area. HuntPilot's public land overlays are a useful way to identify exactly where public access lines fall within Unit 15 before boots hit the ground.

HuntPilot Analysis: Is Unit 15 Worth Applying For?

Based on the data available, Unit 15 is a strong option for hunters who prioritize a high probability of filling a moose tag. The seven-year harvest record — never dipping below 86% success and frequently exceeding 100% — is about as good a trend as a hunter can ask for in any big game unit, let alone a moose unit. Combined with 70% public land and a scouted, huntable elevation range, Unit 15 gives DIY hunters legitimate access to good moose habitat.

Where Unit 15 falls short of "must-apply" status is on the trophy side. The moderate trophy history in the surrounding counties means hunters should draw this tag with realistic expectations: a very good chance at filling a tag on a mature bull, but not necessarily a shot at a unit with an elite, decades-deep trophy pedigree. For hunters whose priority is punching a moose tag and bringing home meat and a solid set of antlers, Unit 15 is a smart target. For hunters chasing a specific top-tier trophy score, it's worth comparing Unit 15's qualitative trophy standing against other Colorado moose units before committing points.

Given how difficult moose tags are to draw anywhere in Colorado — for both residents and nonresidents — a unit with this level of harvest consistency is worth serious consideration when building an application strategy. Hunters should check HuntPilot's Colorado unit pages for current draw odds specific to Unit 15 before finalizing point strategy, since odds shift from year to year based on tag quotas and applicant pools.

How to Apply

Colorado's moose draw operates on a points-based system, and hunters need to plan both the timeline and the layered cost structure carefully.

Note the license fee is required before a hunter can even submit an application — this is separate from the application fee itself and must be factored into the true cost of applying. Nonresidents in particular should budget for the license fee and point fee on top of the application fee even if they don't draw, since maintaining or building points typically requires paying into the point fee structure annually.

Hunters can also check HuntPilot's Colorado state page (/states/co) for the latest application calendar and unit-specific draw information.

Application dates and fees change every draw cycle. For the current deadlines, fees, and draw odds, see HuntPilot's Colorado page at /states/co.

Frequently Asked Questions

What is the terrain like in Unit 15? Unit 15 spans a wide elevation range from 6,658 to 10,801 feet, encompassing valley bottoms, riparian drainages, and higher alpine terrain. With 70% public land and 14% wilderness, hunters have substantial room to roam, though the wilderness-designated areas will require hiking in without motorized or mechanized support. Moose in this terrain typically concentrate around willow bottoms, beaver ponds, and mixed timber transition zones.

What is harvest success like for moose in Unit 15? Harvest success in Unit 15 has been exceptionally strong and consistent. Recorded seasons from 2019 through 2025 show success rates ranging from 86% to as high as 167% (reflecting multiple harvests relative to hunter counts in some seasons), with several years posting a perfect 100%. This is among the more reliable moose units in Colorado based on the available harvest data.

How big are the moose in Unit 15? Trophy data shows the counties overlapping Unit 15 carry a moderate history of trophy-class moose entries. This suggests hunters have a realistic chance at a mature, respectable bull, though the unit doesn't carry the deep trophy pedigree of Colorado's top-tier moose country. Hunters focused purely on trophy potential should weigh this moderate history against other units before committing points.

Is Unit 15 worth applying for? For hunters prioritizing a strong likelihood of filling a moose tag, yes — the seven-year harvest trend is one of the most consistent in the state, rarely dropping below 86% success. Combined with 70% public land access, Unit 15 is a practical, huntable option. Hunters chasing a specific trophy-class bull may want to compare Unit 15's moderate trophy standing against other units before finalizing their application strategy. Check HuntPilot's Colorado unit pages for current draw odds specific to this unit.
