Colorado Unit 1 Elk Hunting Guide

Colorado Unit 1 is a limited-quota elk hunting unit that gives up its tags exclusively through the draw — there is no general season here for any hunter to fall back on. That structure alone tells hunters something important: every bull or cow taken in this unit was harvested by someone who first had to compete for a tag, which typically means lower hunting pressure and more consistent management than what's found in over-the-counter country. With 81,261 total acres and a striking 92% public land base, Unit 1 offers real elbow room for hunters who draw a tag, spanning elevations from 5,008 feet up to 8,858 feet.

This is a unit built around quality control. Colorado Parks and Wildlife manages every hunt code here as limited-quota, including hunts for antlered and either-sex animals, which means the state is actively capping hunter numbers rather than letting pressure run unchecked. For hunters trying to decide whether Unit 1 deserves a spot on their application list, understanding the harvest trends, herd data, and access picture is essential before spending points or application dollars.

HuntPilot Analysis: Is Unit 1 Worth Applying For?

Unit 1 has real strengths, but it's not a slam-dunk pick for every hunter, and the data backs a nuanced take rather than a blanket endorsement.

Start with the access picture: 92% public land on over 81,000 acres is about as good as it gets in Colorado elk country. There's no wilderness designation in this unit, which means access roads and trail systems typically penetrate deeper into the terrain without the foot-and-horseback-only restrictions that come with wilderness boundaries. For DIY hunters, that combination of overwhelming public ownership and non-wilderness status is a meaningful advantage — hunters can plan on covering ground with fewer access barriers than they'd face in a wilderness-heavy limited-entry unit.

The harvest numbers, though, show some volatility that hunters need to factor into expectations. Success rates have ranged widely across recent seasons: 46% in 2022, 38% in 2020, 37% in 2024, and a notable drop to 28% in 2025 with 107 hunters afield and 30 animals harvested. That's a meaningful swing — nearly 20 percentage points between the best and worst of the four years reported — and it suggests conditions (weather, animal distribution, hunting pressure, or herd dynamics) are shifting from year to year rather than holding steady. Hunters should not assume the mid-40% success rates from 2022 represent what to expect going in; the more recent 2025 figure suggests success has softened.

On the herd health side, the survey data raises a flag worth taking seriously. Across six survey years from 2018 to 2024, the average bull:cow ratio sits at 33:100. That's on the lower end for elk herds and points to a bull population that's been worked over relatively hard relative to the cow base — a ratio state biologists and hunters alike would typically want to see higher for a unit with strong bull age structure. This doesn't mean bulls aren't available, but it does mean hunters shouldn't walk in expecting a target-rich environment stacked with mature bulls relative to the cow herd.

Trophy potential in the area is moderate. The counties overlapping Unit 1 carry a moderate history of producing record-book-caliber elk, which suggests some trophy-class bulls have come from this general area over time, but it's not a unit with an outsized or standout trophy pedigree compared to Colorado's elite limited-entry units. Hunters chasing a genuine once-in-a-lifetime bull should treat Unit 1 as a solid possibility rather than a guaranteed trophy factory.

Put together: Unit 1 is worth applying for if a hunter values public land access, a lower-pressure limited-quota structure, and realistic expectations about bull quality and success odds. It's not the unit to prioritize if trophy potential and bulletproof success rates are the top decision criteria. HuntPilot's data shows a unit that rewards hunters who scout hard and adjust to variable conditions rather than one that hands out consistent, easy success.

Harvest Success Rates

Unit 1's harvest data spans four recorded seasons, and the trend line is worth studying closely before committing points or applications to this unit.

• 2022: 158 hunters afield, 72 harvested, 46% success
• 2020: 104 hunters afield, 39 harvested, 38% success
• 2024: 164 hunters afield, 60 harvested, 37% success
• 2025: 107 hunters afield, 30 harvested, 28% success

The pattern shows success peaking in 2022 at 46%, then sliding through 2024 and dropping further in 2025. Hunter numbers have also fluctuated, from a low of 104 in 2020 to a high of 164 in 2024, before falling back to 107 in 2025 — a sign that either quota allocations or draw demand shifted over that window. The declining success rate alongside a drop in hunter numbers in 2025 is a combination worth noting: fewer hunters were afield, yet the percentage successfully tagging out also fell, which points toward tougher hunting conditions or a less available animal population that year rather than simple overcrowding.

Hunters applying for Unit 1 should build a hunt plan around the more conservative end of this range rather than assuming the 46% success year is the baseline. Weather, elk distribution, and access conditions can swing outcomes significantly from one season to the next in this unit.

Trophy Quality

Trophy potential in Unit 1 is best described as moderate. The counties overlapping this unit carry a moderate history of trophy-record production, meaning some quality bulls have come out of the broader area historically, but this is not one of Colorado's headline trophy units. Hunters should note that because trophy records are logged at the county level rather than the exact hunt unit, any records attributed to this area are shared with neighboring units that overlap the same counties — the specific animals could have been taken anywhere within that broader boundary.

Given the bull:cow ratio data discussed below, hunters chasing an exceptional, mature bull should temper expectations. A ratio in the low-30s per 100 cows, sustained across multiple survey years, generally correlates with a bull segment that skews younger, since higher hunting pressure on bulls tends to suppress the population from reaching older age classes in high numbers. That said, moderate trophy history means quality bulls are not absent from this landscape — they're simply not the norm, and hunters should treat a mature bull encounter as a bonus rather than an expectation.

Herd Health & Population Trends

The wildlife survey data for Unit 1 covers six survey years between 2018 and 2024, with an average bull:cow ratio of 33:100. This is a below-average ratio for elk herds in the West, where wildlife managers typically aim for higher post-season bull:cow ratios to maintain a healthier age structure and more mature bulls in the population.

A 33:100 average sustained across six survey years is not a small-sample anomaly — it's a consistent, multi-year trend, which makes it a more reliable signal than a single-year spike or dip would be. This ratio suggests bulls are being harvested at a rate that keeps the bull segment of the population relatively lean compared to cows. For hunters, the practical takeaway is twofold: first, cow encounters will likely outnumber bull encounters significantly in the field; second, the bulls that are present may skew toward younger age classes given the sustained pressure implied by this ratio.

This data doesn't necessarily signal a herd in decline — it may simply reflect Colorado's management strategy for this unit, balancing hunter opportunity against bull escapement. But hunters should walk in with calibrated expectations about bull density rather than assuming a healthy overall elk population automatically means abundant mature bulls.

Access & Terrain

Unit 1 offers exceptional public land access by any Western standard: 92% of the unit's 81,261 total acres sits on public ground, meaning the vast majority of this unit is open to hunters without needing private land permission or leases. Combined with zero percent wilderness designation, this unit is structured for practical, motorized-adjacent access — hunters aren't fighting the same foot/horseback-only restrictions that come with wilderness-heavy units elsewhere in Colorado.

Elevation in the unit ranges from 5,008 feet up to 8,858 feet, a spread of nearly 3,900 feet that offers meaningful terrain diversity. Lower elevations in this range likely hold sagebrush and transitional habitat, while the upper end climbs into more heavily timbered, higher-country terrain typical of Colorado elk range. This elevation gradient gives hunters options to hunt lower initially and push higher as conditions and elk movement dictate, without needing to leave the unit boundary.

Given the non-wilderness classification and heavy public land ownership, hunters should expect a mix of road-accessible country and pack-in terrain reachable on foot, rather than country that demands wilderness permits or stock support to access. This makes Unit 1 a genuinely appealing DIY option relative to units where public access is fragmented or locked behind private inholdings.

How to Apply

Because Unit 1 has no general season, every hunt here — including hunts for antlered and either-sex elk — runs exclusively through Colorado's limited-quota draw system. There is no over-the-counter fallback option in this unit; hunters must apply and be selected in the draw to hunt here at all.

Colorado's draw system uses true preference points, meaning the state's highest point holders are awarded tags first before any remaining tags are distributed. This is not a weighted lottery — a high enough point level in Colorado has historically been sufficient to guarantee a tag on many hunts, which makes point strategy a real and meaningful lever for hunters targeting Unit 1. Residents and nonresidents apply through separate pools, and nonresidents should expect to need a higher point level than residents to be competitive for the same hunt code, given Colorado's allocation structure between resident and nonresident applicants.

Hunters should decide early whether they're applying as a resident or nonresident, since draw dynamics and point requirements diverge significantly between the two pools. For hunters newer to the state's point system, it's worth understanding that a successful draw will consume the accumulated preference points used to secure that tag — points don't carry forward after a successful draw, so hunters typically rebuild from a lower point level for their next application cycle.

Application dates, fees, and current point requirements change every draw cycle, so this article won't cite specific numbers that will go stale. For the current deadlines, application fees, and draw odds by point level for Unit 1, see HuntPilot's Colorado state page at /states/co.

Frequently Asked Questions

Is Colorado Unit 1 worth applying for? Unit 1 is worth considering for hunters who prioritize public land access and a limited-quota, lower-pressure structure. With 92% public land and no wilderness restrictions, DIY access is strong. However, hunters should weigh the declining harvest success trend (28% in 2025 versus 46% in 2022) and a below-average bull:cow ratio against those access advantages before committing points to this unit.

What is harvest success like in Unit 1? Harvest success has varied significantly across recent seasons: 46% in 2022, 38% in 2020, 37% in 2024, and 28% in 2025. The trend suggests success has softened in the most recent reported season, so hunters should plan around a more conservative success expectation rather than the higher historical figures.

What is the terrain like in Colorado Unit 1? The unit spans elevations from 5,008 to 8,858 feet across 81,261 total acres, with 92% public land ownership and no wilderness designation. This combination offers a mix of lower-elevation and higher-country terrain accessible without the restrictions that come with wilderness boundaries, making it favorable for DIY hunters willing to cover ground on foot.

How big are the elk in Unit 1? Trophy potential in the area is moderate — the counties overlapping this unit carry some history of producing trophy-class bulls, but it is not among Colorado's premier trophy units. Combined with a below-average bull:cow ratio (33:100 average across six survey years), hunters should expect bull encounters to lean toward younger age classes, with a mature, trophy-caliber bull being a possibility rather than an expectation.

Does Unit 1 have a general season for elk? No. Every hunt in Unit 1 is limited-quota and allocated through Colorado's draw system, including hunts for antlered and either-sex elk. There is no over-the-counter or general season option in this unit — hunters must draw a tag to hunt here.
