Colorado Unit 86 Mule Deer Hunting Guide

Colorado Unit 86 sits in some of the more rugged high-country terrain the state has to offer, with elevations ranging from 6,169 feet up to 14,036 feet across 317,569 total acres. For hunters researching mule deer opportunity in this part of Colorado, Unit 86 is entirely a limited-quota draw unit — there is no general season here. Every hunt, including hunts for antlered bucks, requires a successful draw application. That structure alone tells hunters a lot about what to expect: controlled hunter numbers, a management-driven approach to the herd, and a unit that rewards patience in the application process.

With 58% public land and 25% wilderness designation, Unit 86 offers real DIY potential for hunters willing to get into rugged, vertical country. The wilderness component in particular means hunters should expect foot and horseback access in the highest-elevation portions of the unit, with the terrain running from lower foothill country up into true alpine basins near the unit's elevation ceiling. This is not a unit where hunters roll up and glass from the truck — the elevation spread from just over 6,000 feet to over 14,000 feet demands physical preparation and a willingness to hunt vertical terrain.

Forum chatter around this unit and its neighbors (69, 691, 84, and 861) confirms what the data shows: this is considered classic Western Slope-adjacent high country, hunted seriously by both residents and out-of-state hunters who put in for third-season tags in the area. Hunters coming from flat country should budget extra time to acclimate and scout before their hunt begins.

HuntPilot Analysis: Is Unit 86 Worth Applying For?

The harvest numbers here tell an interesting and somewhat volatile story. In the 2025 season, 2,016 hunters harvested 1,078 animals for a 53% success rate — a dramatic jump in both hunter numbers and success compared to prior years. Going back further, 2024 saw 901 hunters harvest 336 animals (37% success), 2023 saw 844 hunters take 395 animals (47% success), and 2022 produced 792 hunters harvesting 343 animals (43% success).

That swing from roughly 40-47% success in 2022-2024 up to 53% in 2025, alongside more than double the hunter numbers, suggests either a meaningful change in tag allocation, hunt structure, or both. Hunters should treat 2025 as an outlier data point rather than the new baseline, and weigh the more consistent 2022-2024 window (which hovers in the low-to-mid 40% range) as the more reliable expectation for planning purposes. Regardless of which year is used, this is a unit where a healthy percentage of hunters who draw a tag are connecting on an animal — success rates in the 37-53% range across four consecutive years indicate a functional, huntable population with reasonable opportunity, not a unit where tags go mostly unfilled.

On the survey side, the available data shows a buck:doe ratio of 34:100 from the 2024 survey year. This is a single survey year, and a 34:100 ratio is on the lower end for a healthy mule deer herd, suggesting a buck-limited population relative to doe numbers — not unusual for a heavily-hunted, high-elevation Colorado unit, but worth factoring into expectations. With only one year of survey data available, hunters shouldn't over-interpret this single data point as a definitive trend; it's a snapshot, not a multi-year pattern.

Trophy history in the counties overlapping Unit 86 shows a moderate trophy record. This isn't a unit defined by consistent, elite trophy production, but it has produced trophy-class animals historically. Because record-book entries are attributed at the county level rather than the unit level, this trophy history is shared across Unit 86 and its neighboring units — the animals contributing to that record could have come from anywhere within the overlapping counties, not necessarily from within Unit 86's exact boundary. Given that moderate designation, hunters chasing a genuine trophy-caliber buck should treat Unit 86 as a unit with some upside but not a unit where big bucks are a given — the forum posts referencing this general area (and the neighboring Unit 44 thread specifically) echo this, with longtime hunters acknowledging that management pressure and hunter numbers have changed what these units produce compared to years past.

Putting it together: Unit 86 is worth applying for if a hunter values a genuine backcountry, physically demanding hunt with solid draw-year success rates and public land access, and is not solely fixated on trophy potential. It is a reasonable target for hunters willing to work hard in vertical, wilderness-adjacent terrain rather than a unit hunters should chase purely for record-book aspirations.

Access & Terrain

Unit 86's terrain profile is defined by extremes. The elevation range — 6,169 to 14,036 feet — spans nearly 8,000 vertical feet within a single unit, meaning hunters could be hunting sagebrush foothills and high alpine basins within the same trip, depending on where in the unit they draw and hunt. That's an unusually wide elevation band, and it has direct implications for hunt strategy: early-elevation deer behave differently than deer pushed high into basin country, and hunters should plan their approach around where in that range they intend to focus.

With 58% public land, more than half the unit is open to public access, giving DIY hunters a legitimate base to work from, though the remaining 42% in private hands means boundary awareness and permission-seeking will still matter in certain drainages. The 25% wilderness designation is significant — a quarter of the unit falls under wilderness protection, which means no mechanized or motorized access in those areas. Hunters targeting the wilderness portions of Unit 86 should plan on foot or horseback access only, and should budget more time and physical conditioning than a road-accessible hunt would require. Unlike Wyoming, Colorado places no guide requirement on nonresidents hunting wilderness areas, so DIY hunters are free to access these areas independently — but the terrain itself is the real obstacle, not any regulatory barrier.

Forum posts referencing this unit and its neighbors describe it as serious, rugged country that draws hunters willing to make a real trip out of it — groups traveling from out of state and basing out of nearby towns to hunt Unit 86 alongside adjacent units during the same trip. That regional pattern reinforces that this is considered a multi-day, backcountry-style hunt rather than a quick in-and-out weekend hunt.

Trophy Quality

Trophy potential in Unit 86 is best described as moderate. The counties overlapping this unit carry a moderate trophy record history, meaning trophy-class bucks have come from this general area historically, but production has not been consistent or exceptional enough to place Unit 86 among Colorado's elite trophy units. Because these records are logged by county rather than by unit boundary, that trophy history is shared with neighboring units in the same overlapping counties — a notable buck attributed to this area could realistically have come from Unit 86 or from an adjacent unit like 69, 691, 84, or 861.

Hunters chasing a genuine trophy buck in Unit 86 should go in with realistic expectations: this is a unit capable of producing a special buck, as forum posts about the surrounding units suggest hunters have swung for the fences here in past seasons, but it is not a unit where trophy bucks are the norm. The buck:doe ratio of 34:100 from the 2024 survey also suggests a population skewed toward fewer mature bucks relative to does, which aligns with the moderate — rather than strong or exceptional — trophy characterization.

Harvest Success Rates

Unit 86's harvest data across four recent seasons shows meaningful year-to-year variability, but overall points to a unit where drawn hunters have a solid chance of filling their tag. The numbers by year:

• 2025: 2,016 hunters, 1,078 harvested, 53% success
• 2024: 901 hunters, 336 harvested, 37% success
• 2023: 844 hunters, 395 harvested, 47% success
• 2022: 792 hunters, 343 harvested, 43% success

The jump in both hunter numbers and success rate in 2025 stands out against the more stable 2022-2024 period. Hunters using this data to plan a hunt should lean on the three-year trend from 2022-2024 as the more dependable baseline (37-47% success), while recognizing that 2025 could represent either a genuine improvement in hunt structure or a one-year anomaly. Either way, four consecutive years of success rates well above a third of hunters filling tags indicates this is a productive unit for hunters who draw, not a unit where tags routinely go unused.

How to Apply

Because Unit 86 has no general season, every hunter — resident or nonresident — must go through Colorado's draw system to hunt mule deer here, including for antlered bucks. There is no over-the-counter option for this unit.

Colorado's draw system for deer operates as a hybrid model: a portion of tags go to the highest preference point holders first, while the remainder are allocated through a weighted random draw where each application year adds an additional entry. Colorado runs true preference at the top end of the point spectrum, meaning a high enough point total can effectively guarantee a tag on many hunts over time — this is not a pure lottery system. Resident and nonresident applicants draw from separate pools, and nonresidents should expect the point investment required to draw a quality hunt in a unit like 86 to run longer than for residents.

Because this is a limited-quota unit for all deer hunts, hunters serious about drawing here should be checking current point requirements and draw statistics before applying, since these figures shift from year to year based on quota changes and applicant demand. Application dates, fees, and draw odds change every cycle — for current deadlines, fees, and draw statistics specific to Unit 86, hunters should consult HuntPilot's Colorado state page for the most current numbers rather than relying on historical figures.

Frequently Asked Questions

What is the terrain like in Colorado Unit 86? Unit 86 spans an extreme elevation range from 6,169 feet to 14,036 feet, meaning hunters may encounter everything from lower foothill terrain to true high alpine basins depending on where they hunt. With 58% public land and 25% wilderness, much of the unit is accessible to DIY hunters, but the wilderness-designated portion requires foot or horseback travel only, and the vertical relief throughout the unit makes this a physically demanding hunt.

What is harvest success like in Unit 86? Success rates have ranged from 37% to 53% over the four most recent seasons on record (2022-2025), with the majority of years falling in the 37-47% range. That's a solid success rate for a limited-quota mule deer unit, suggesting hunters who draw a tag here have a reasonable chance of connecting on an animal.

How big are the mule deer in Unit 86? Trophy production in the counties overlapping Unit 86 is best described as moderate — the area has produced trophy-class bucks historically, but not with the frequency or consistency of Colorado's top-tier trophy units. Since trophy records are tracked by county rather than unit boundary, this history is shared with neighboring units in the same overlapping counties. Hunters should view Unit 86 as having some trophy upside without treating it as a dedicated trophy destination.

Is Unit 86 worth applying for? For hunters prioritizing a rugged, physically demanding backcountry hunt with reasonable harvest success and substantial public land access, yes — the harvest data supports a functional, huntable deer population, and the terrain offers a genuine wilderness experience. Hunters purely chasing trophy potential should temper expectations given the unit's moderate trophy history and a below-average buck:doe ratio recorded in the 2024 survey.

Do nonresidents need a guide to hunt the wilderness portion of Unit 86? No. Colorado does not require nonresidents to hire a guide or outfitter to hunt wilderness areas, unlike some other western states. Nonresident hunters are free to access the 25% wilderness portion of Unit 86 independently, though the remote, foot/horseback-only nature of that terrain means proper preparation and conditioning are essential.
