Colorado Unit 37 Moose Hunting Guide

Colorado Unit 37 sits among the state's most talked-about moose destinations, and for good reason: this is a limited, small-pond hunt that consistently produces strong success rates for the hunters lucky enough to draw a tag. Spanning 338,173 acres with elevations ranging from 6,998 to 14,254 feet, Unit 37 offers a dramatic cross-section of terrain, from lower valley floors to true alpine country near timberline. With 75% of the unit in public ownership, access is broadly favorable for hunters who put in the scouting time.

Moose hunting in Colorado is a different animal than most western big game pursuits — tags are scarce, demand is high, and the animals themselves are famously unhurried once located. Unit 37 has built a reputation on forums and among Colorado hunters as one of those units where, if a hunter can actually draw the tag, the hunt itself is comparatively straightforward. That reputation is backed up by recent harvest data, which is exactly what this article breaks down.

Harvest Success Rates

Unit 37's moose harvest data over the past several seasons shows a unit that, in most years, rewards the hunters who draw tags. In 2025, 44 hunters harvested 38 animals for an 86% success rate — the highest hunter volume and one of the strongest success rates in the recent record. In 2024, a smaller draw of 15 hunters produced 13 harvests, an 87% success rate, matching 2025 as the two standout years in this dataset.

Earlier seasons tell a more moderate story. In 2023, 23 hunters harvested 12 animals for a 52% success rate, and in 2022, 17 hunters took 10 animals for 59%. The 2021 and 2020 seasons were identical on paper — 20 hunters and 12 harvests each year, both landing at 60% success. The oldest data point in this set, 2019, shows 14 hunters and 6 harvests, a 43% success rate that stands as the low point of the seven-year window.

Taken together, this data shows a unit where success has generally trended upward, with the two most recent years (2024 and 2025) posting the best results by a clear margin. That said, hunters should recognize that moose hunts in Colorado are almost always low-volume draws, and swings of 10-15 percentage points year to year are normal in a hunt with this few participants. The broader takeaway: hunters who draw Unit 37 have historically finished their hunt with a moose more often than not, and recent years have pushed those numbers even higher.

Trophy Quality

Moose trophy potential in the counties overlapping Unit 37 falls into the moderate category based on available trophy records. This isn't a unit with a deep, decades-long pedigree of chart-topping bulls, but it also isn't a blank slate — the area has produced trophy-class animals over time, just not with the frequency or consistency seen in Colorado's most storied moose country.

For hunters whose primary objective is antler size, Unit 37 should be viewed as a solid opportunity rather than a guaranteed trophy destination. As several forum hunters have noted, most applicants pursuing this unit — particularly on cow tags — are focused on meat rather than headgear, and the harvest data supports that framing: high success rates on a hunt where many participants aren't scoring antlers at all. Hunters specifically chasing a bull with significant mass and paddle spread should treat this as a bonus outcome rather than the expectation, and should lean on the qualitative trophy history here rather than any promise of a record-class animal.

Herd Health & Population Trends

While detailed bull:cow or population survey figures aren't included in the available data for Unit 37, the harvest trend itself offers an indirect read on herd health. A moose population that consistently supports success rates in the 50-90% range across nearly a decade, without a shrinking harvest total or collapsing success rate, generally reflects a stable to healthy population capable of sustaining current tag levels. The jump in both hunter numbers and harvest totals in 2024 and 2025 suggests wildlife managers may have had confidence to modestly increase tag allocations, which is typically a sign of a herd that's holding steady or improving. Hunters wanting the latest population survey data specific to Unit 37 should check HuntPilot's unit page, which tracks this information as it's published by the state.

Access & Terrain

Unit 37 covers a wide elevational band — from 6,998 feet at its lowest to 14,254 feet at its highest points — meaning hunters could be glassing sage-and-willow bottoms one day and working alpine basins near timberline the next. Moose are creatures of willow-choked drainages, wet meadows, and timbered edges near water, and the elevation range here supports that habitat type across a broad swath of the unit's 338,173 acres.

Public land makes up 75% of Unit 37, which gives DIY-minded hunters a strong base of huntable ground without needing to negotiate private access in most cases. That said, wilderness designation covers only 6% of the unit, meaning the vast majority of huntable public land sits outside formally designated wilderness. This is a meaningful point for logistics planning: hunters can generally access much of the unit's public ground with mechanized equipment or vehicle-supported camps, rather than being forced into pack-in-only wilderness travel. It also means this unit does not carry the guide requirements that apply to wilderness hunting in other states — Colorado has no such mandate regardless of wilderness percentage.

Forum accounts describing Unit 37 consistently reference it as a "small pond" — a reflection of how few tags are issued relative to the unit's size, rather than a statement about habitat quality. Hunters who draw should expect to do real scouting work across a large unit rather than relying on a handful of known hotspots, since low tag numbers mean there isn't a large community of prior hunters sharing detailed intel. HuntPilot's map tools, including public land overlays, can help hunters narrow down drainages and elevation bands worth glassing before ever setting foot in the unit.

HuntPilot Analysis: Is Unit 37 Worth Applying For?

For hunters focused on filling a moose tag and putting meat in the freezer, Unit 37 is worth serious consideration. The success rates in 2024 and 2025 — 87% and 86% respectively — are excellent by any standard, and even the unit's weaker years in this dataset (2019's 43% and 2023's 52%) still represent a coin-flip-or-better chance at connecting. Few big game hunts in the West offer this kind of success profile once a tag is in hand.

The catch, as every forum thread on Colorado moose points out, is drawing the tag itself. Moose tags in Colorado are extremely limited, and Unit 37 is no exception — demand for these tags is heavily contested every year, with far more applicants than available permits. This is a long-term point investment for most nonresidents and a patience game even for many residents. Hunters should not expect to draw Unit 37 quickly, and should check HuntPilot's unit page for the most current draw odds and point requirements before building an application strategy.

Trophy hunters chasing a wall-worthy bull should temper expectations. The moderate trophy history in the surrounding counties means Unit 37 can produce a quality bull, but it's not positioned as a marquee trophy unit on the level of Colorado's best-known moose country. Hunters prioritizing antler size might want to weigh this unit's excellent success rates against other options with deeper trophy pedigrees.

Bottom line: Unit 37 is a strong pick for hunters who value a high-probability hunt with good public access (75%) and manageable terrain outside of heavy wilderness restriction. It's a weaker pick for hunters whose primary goal is a record-class bull.

How to Apply

Colorado's moose application process runs through a structured draw with separate resident and nonresident fee schedules.

Colorado residents accumulate preference points automatically in years they apply but don't draw, and those points factor into future draw cycles for moose. Nonresidents should be aware that drawing a moose tag consumes accumulated points, resetting them near zero for future applications.

Moose habitat in units like this typically centers on willow-lined drainages, wet meadows, and timbered edges near water sources, which occur across a wide band of this unit's elevation profile.

What is harvest success like in Unit 37 for moose? Recent success rates have been strong, with 86% in 2025 and 87% in 2024. Prior years were more moderate, ranging from 43% in 2019 up to 60% in both 2020 and 2021. Overall, the unit has trended toward higher success in its most recent seasons.

How big are the moose in Unit 37? Trophy potential is best described as moderate based on available records from the surrounding counties. The area has produced trophy-class animals but doesn't carry the deep trophy pedigree of Colorado's top moose units. Most hunters drawing tags here — especially cow tags — are pursuing meat first, with antler size a secondary consideration.

Is Unit 37 worth applying for? For hunters prioritizing a high-probability hunt, yes — recent success rates above 85% make this an attractive unit once a tag is drawn. For hunters chasing a top-end trophy bull, the moderate trophy history suggests other units may offer better odds at a record-class animal. Moose tags here are heavily contested regardless of goal, so hunters should check HuntPilot's unit page for current draw odds before committing to a long-term point strategy.

Does Unit 37 require a guide for nonresident hunters? No. While the unit contains some wilderness acreage (6%), Colorado does not impose a state-mandated guide requirement for nonresident hunters in wilderness areas, unlike some other western states. Nonresidents are free to hunt Unit 37 DIY-style, provided they've successfully drawn a tag.
