Colorado Unit 37 Elk Hunting Guide

Colorado Unit 37 is a limited-quota elk destination spanning 338,173 acres, with elevations ranging from 6,998 to 14,254 feet. There is no general season here — every elk hunt in Unit 37 is a limited-quota draw hunt, which means hunters at every experience level are applying through the same controlled framework rather than buying an over-the-counter tag. For hunters researching Colorado Unit 37 elk hunting, understanding that draw-only structure is the first and most important piece of the puzzle.

With 75% of the unit in public ownership and 6% designated wilderness, Unit 37 offers a substantial base of accessible public ground for hunters willing to get into rugged, high-elevation terrain. The unit's elevation spread — nearly 7,300 vertical feet from valley floor to peak — means hunters can find everything from lower sagebrush and timber transition zones to true alpine basins above 13,000 feet, depending on when and where they draw.

HuntPilot Analysis: Is Unit 37 Worth Applying For?

The honest answer depends heavily on what a hunter is looking for. Harvest data pulled from HuntPilot shows Unit 37 running a consistent 6-12% success rate across the past five seasons, with 2025 posting 509 harvested elk out of 5,291 hunters (10% success), 2024 at 400 harvested out of 3,910 hunters (10%), 2023 at 442 out of 4,227 (10%), 2022 at 571 out of 4,707 (12%), and 2021 at 303 out of 4,941 (6%). That's a unit that produces steady, if unspectacular, success — not a place where hunters should expect easy tags or high percentages, but also not a unit where success has been declining sharply. The 2022 season stands out as the strongest recent year, and 2021 as the softest, with the three most recent years all landing right at 10%.

Hunter volume is worth paying attention to as well. Unit 37 drew over 5,000 hunters in 2025, up significantly from the roughly 3,900-4,700 range seen in the previous four years. More hunters afield without a corresponding bump in success rate suggests pressure is increasing, which is a relevant consideration for anyone weighing whether to apply here versus a less-crowded alternative.

On the herd health side, survey data collected across six years (2018-2024) shows an average bull-to-cow ratio of 41:100. That's a reasonable, biologically plausible ratio for a limited-quota elk unit — not eye-popping, but indicative of a herd that is managed for sustained bull representation rather than maximum harvest. It's a ratio that supports a reasonably mature bull component in the herd without suggesting an exceptional or outlier bull class.

Trophy history for the counties overlapping Unit 37 is limited. The available records point to a modest trophy pedigree rather than a unit known for consistently producing book-class bulls. Hunters chasing a genuine trophy hunt should treat Unit 37 as a solid opportunity and experience-focused draw rather than a unit with a strong track record of exceptional bulls. That said, with 75% public land and a bull:cow ratio in a healthy range, there's enough here to make the unit worth consideration for hunters prioritizing a quality public-land experience over trophy odds alone.

Bottom line: Unit 37 is worth applying for if a hunter values public-land access (75%), a biologically sound bull:cow ratio, and is comfortable with a moderate, single-digit-to-low-teens success rate in a limited-quota structure. It is not the unit to chase if trophy potential is the primary goal — the data simply doesn't support that expectation here.

Harvest Success Rates

Looking at the five-year harvest trend gives a clearer picture of what hunters can realistically expect:

• 2025: 5,291 hunters, 509 harvested, 10% success
• 2024: 3,910 hunters, 400 harvested, 10% success
• 2023: 4,227 hunters, 442 harvested, 10% success
• 2022: 4,707 hunters, 571 harvested, 12% success
• 2021: 4,941 hunters, 303 harvested, 6% success

The pattern here is remarkably stable at the 10% mark for three consecutive years (2023-2025), bracketed by a stronger 2022 (12%) and a weaker 2021 (6%). This consistency is useful for planning purposes — hunters should walk into Unit 37 expecting something in the high single digits to low double digits for overall success, understanding that unit-wide totals blend all hunt types and sexes together. Individual results will vary based on specific hunt code, time afield, and hunter effort, but the baseline expectation should be calibrated to this historical range rather than to outlier years in either direction.

Trophy Quality

Trophy records tied to the counties overlapping Unit 37 are limited, pointing to modest trophy potential rather than a strong history of book-class bulls. Hunters should keep in mind the county-level nature of this data — any record-book entries attributed to these counties could reflect animals taken across Unit 37 and its neighboring units, not necessarily within Unit 37's exact boundaries.

Given the bull:cow ratio of 41:100 recorded across the six survey years, the herd structure suggests a working population with a reasonable number of bulls surviving to maturity, but the trophy record data does not support an expectation of frequent exceptional or elite-class bulls coming out of this area. Hunters should view Unit 37 as a solid public-land elk hunting opportunity rather than a trophy unit, and should set expectations accordingly — most elk taken here will represent a quality, hard-earned hunt in big, rugged country rather than a record-book pursuit.

Herd Health & Population Trends

The six years of survey data (2018-2024) show an average bull:cow ratio of 41:100 for Unit 37. This is a biologically normal ratio for a managed, limited-quota elk herd — well within the range seen across healthy Western elk populations, and notably not an outlier that would suggest either a struggling bull segment or an unusually bull-heavy population. Rather than one standout year skewing the average, this figure reflects a genuine multi-year trend, which gives it more credibility than a single-season snapshot.

For hunters, this ratio translates to a herd that should have a workable number of bulls available relative to cows, supporting the steady 6-12% success rates seen in recent harvest data. It doesn't indicate the kind of bull-rich herd that would push success rates or trophy quality dramatically higher, but it also doesn't flag any red concerns about herd sustainability or bull recruitment.

Access & Terrain

Unit 37 covers 338,173 acres with 75% public land, giving DIY hunters a strong base of accessible ground to hunt without needing to negotiate private land access. That said, the remaining 25% is private, so hunters should still check specific land ownership boundaries carefully before planning routes, particularly near lower-elevation valley floors where private ranches often sit.

Elevation in the unit ranges from 6,998 feet up to 14,254 feet — a massive vertical range that puts true alpine terrain within the unit's boundaries alongside lower foothill and transition-zone country. This spread means hunt strategy should shift significantly depending on time of year and specific hunt code drawn: lower elevations will hold elk earlier in the season before snow pushes animals higher or lower depending on conditions, while the highest basins near 13,000-14,000 feet offer classic high-country hunting for those willing to pack in.

Wilderness acreage sits at 6% of the unit, a relatively small portion of the total footprint. This means the vast majority of Unit 37's public land is non-wilderness, multiple-use Forest Service or BLM ground — accessible by vehicle-based scouting and traditional access methods rather than requiring extensive wilderness-only foot or stock travel. Hunters planning a trip should use HuntPilot's mapping tools to identify specific public land boundaries, elevation bands, and water sources within the unit to build out a scouting plan tailored to the hunt code and time of year they draw.

How to Apply

Because Unit 37 has no general season, every elk hunt here — including hunts for antlered or either-sex animals — is allocated through Colorado's limited-quota draw system. There is no over-the-counter option for this unit; hunters must apply and be selected through the draw to hunt elk here.

Colorado's draw system uses true preference points, meaning hunters with the highest point totals are awarded tags first in the preference portion of the draw. This gives Colorado's system real predictive value: hunters can use historical draw data to understand roughly how many points are typically needed to draw a specific hunt code in Unit 37. Colorado maintains separate resident and nonresident applicant pools, and nonresidents should expect the draw to be meaningfully more competitive than for residents on most hunt codes in a unit like this.

Hunters should decide upfront whether they're applying as a resident or nonresident, since fees, point structures, and competitiveness all differ between the two pools. Because this unit offers no general-season fallback, there is no walk-up option if a hunter doesn't draw — unused points simply carry forward to future application cycles.

Application dates, fees, and current draw odds change every cycle and are not included here. For up-to-date deadlines, costs, and draw odds specific to each hunt code in Unit 37, hunters should consult HuntPilot's Colorado state page or the current big game application information published by Colorado Parks and Wildlife.

Frequently Asked Questions

Is Colorado Unit 37 worth applying for elk? It depends on the hunter's priorities. The data shows a consistent 6-12% harvest success rate over the past five years, a biologically healthy bull:cow ratio of 41:100, and strong public land access at 75% of the unit's 338,173 acres. Trophy records for the area are limited, so hunters chasing a book-class bull may want to look elsewhere, but those prioritizing a solid public-land elk hunting experience with reasonable odds of success should find Unit 37 a reasonable option.

What is the terrain like in Unit 37? Unit 37 spans an enormous elevation range from 6,998 feet to 14,254 feet, encompassing everything from lower transitional country to true high-alpine basins. With 75% public land and only 6% designated wilderness, most of the unit is accessible multiple-use public ground rather than remote wilderness-only terrain, though the vertical relief means hunters should be prepared for serious elevation gain depending on where they hunt.

What is harvest success like in Unit 37? Recent harvest data shows success rates of 10% in 2025, 10% in 2024, 10% in 2023, 12% in 2022, and 6% in 2021. The unit has been remarkably consistent at the 10% mark for the last three recorded seasons, giving hunters a reliable baseline for planning expectations.

How big are the elk in Unit 37? Trophy record data for the counties overlapping Unit 37 shows a limited history of entries, suggesting modest rather than exceptional trophy potential. The bull:cow ratio of 41:100 across six survey years supports a reasonably healthy bull segment in the herd, but hunters should not expect Unit 37 to be a unit that regularly produces elite or record-class bulls based on available data.

Does Unit 37 have a general elk season? No. Every elk hunt in Unit 37 — including hunts for antlered and either-sex animals — is allocated through Colorado's limited-quota draw system. There is no over-the-counter or general-season option available in this unit; hunters must apply and draw a tag to hunt elk here.
