Colorado Unit 86 Elk Hunting Guide

Colorado Unit 86 is a limited-quota elk unit spanning 317,569 acres of high-relief terrain, with elevations ranging from 6,169 to 14,036 feet. For hunters researching Colorado Unit 86 elk hunting, the unit offers no general season — every elk hunt here runs through the draw, including tags for antlered and either-sex animals. That structural detail matters immediately: there's no over-the-counter fallback in this unit, so a hunter's entire strategy has to be built around the draw from the outset.

With 58% public land and 25% wilderness designation, Unit 86 combines legitimate public access with genuinely rugged, remote country. The elevation swing of nearly 8,000 feet from valley floor to peak means this unit holds everything from lower sagebrush and timber transition zones to true alpine basins above treeline. That range creates diverse elk habitat, but it also demands physical preparation and terrain-specific scouting from anyone planning to hunt it.

HuntPilot Analysis: Is Unit 86 Worth Applying For?

The honest answer requires weighing a few competing signals from the data. On one hand, harvest success in Unit 86 has been reasonably strong for a limited-quota western elk unit, running as high as 22% in the 2025 season. On the other hand, the bull:cow ratio recorded across six survey years (2018-2024) averages just 18:100 — a low ratio that signals a bull-heavy harvest pressure relative to the cow population, or a herd structure that isn't accumulating mature bulls at a high rate. This is a meaningful data point for hunters weighing quality of experience against tag difficulty.

Trophy history for the counties overlapping Unit 86 is limited. There isn't a deep or consistent record of trophy-class bulls coming out of this area, which tempers expectations for hunters chasing a wall-worthy animal. This doesn't mean big bulls don't exist here — it means the documented trophy pedigree is thin, and hunters should treat this as an opportunity-and-experience unit rather than a bucket-list trophy destination.

Where Unit 86 earns its keep is in the combination of solid public access (58%), meaningful wilderness character (25%), and a harvest success rate that has trended upward in the most recent data year. The terrain diversity — from mid-elevation timber to high alpine cirques near 14,000 feet — gives hunters multiple tactical options depending on time of year, physical capability, and how elk are using the country. For a hunter who values a legitimate limited-quota hunt with decent success odds and wants to prioritize experience and solitude over trophy potential, Unit 86 is worth serious consideration. For a hunter whose primary goal is a record-class bull, the data doesn't support strong optimism, and time might be better spent researching units with deeper trophy histories.

Harvest Success Rates

Unit 86's harvest data across the last four recorded seasons shows a unit with fluctuating pressure and improving efficiency:

• 2025: 1,230 hunters, 274 harvested, 22% success
• 2024: 3,868 hunters, 584 harvested, 15% success
• 2023: 4,282 hunters, 523 harvested, 12% success
• 2022: 1,964 hunters, 241 harvested, 12% success

The trend line here is worth unpacking. Hunter numbers spiked dramatically in 2023 and 2024 (over 3,800 hunters afield both years) before dropping sharply back to 1,230 in 2025 — likely reflecting a reduction in issued tags or a shift in hunt structure. Despite fewer hunters in the field in 2025, harvest success nearly doubled compared to the two prior years, jumping from the 12-15% range up to 22%. This kind of pattern often points to reduced hunting pressure translating directly into a better per-hunter opportunity, which is a meaningful signal for anyone comparing this unit against others with similarly-sized quotas.

For context, a 22% success rate on a limited-quota elk hunt is solid, though not exceptional, by western elk-hunting standards. It reflects a unit where hunters who do their homework and put in the physical effort across this elevation gradient have a realistic chance of connecting, without it being an easy tag to fill.

Trophy Quality

Trophy potential in Unit 86 is best described as limited based on the available record-book history for the counties overlapping this unit. There isn't a strong or consistent pedigree of trophy-class bulls documented from this area, and hunters should calibrate expectations accordingly. This is not unusual for units with heavier hunting pressure history (as reflected in the 2023-2024 hunter counts) combined with a bull:cow ratio that skews toward fewer mature bulls relative to cows.

That said, limited trophy history doesn't mean the unit is devoid of mature animals — it means hunters shouldn't build a trip around the expectation of encountering an elite-class bull. Unit 86 is better approached as a unit offering a genuine, physically demanding elk hunt with a fair shot at a representative bull, rather than a trophy unit in the traditional sense. Hunters strictly focused on maximizing trophy odds should compare this unit's qualitative trophy assessment against other Colorado units with deeper, more consistent record-book histories before committing points or applications here.

Herd Health & Population Trends

The wildlife survey data available for Unit 86 spans six survey years from 2018 to 2024, showing an average bull:cow ratio of 18:100. This is a notably low ratio for elk — well below the ratios seen in units managed more conservatively for bull escapement, and it suggests a herd structure shaped by consistent hunting pressure on bulls relative to the cow segment of the population.

A bull:cow ratio in this range typically correlates with lower odds of encountering older-age-class bulls, since fewer bulls are surviving multiple seasons to reach full maturity. This aligns with the limited trophy history noted above — the two data points reinforce each other. Hunters should treat this ratio as a genuine indicator of herd bull demographics rather than a survey anomaly, since it reflects an average taken across six separate survey years rather than a single-year spike.

For hunters weighing quality of experience, this means Unit 86 is likely to produce more encounters with younger bulls and cow/calf groups than with mature, herd-bull-class animals. That's a legitimate elk hunting experience — but it's a different expectation than units with bull:cow ratios more favorable to trophy-age escapement.

Access & Terrain

Unit 86 offers 58% public land, meaning the majority of the unit is accessible to hunters without requiring private land arrangements, though the remaining 42% is private and hunters need to be diligent about boundaries, particularly on the fringes of the unit at lower elevations where private ranchland often dominates.

The 25% wilderness designation within the unit is significant. Wilderness areas prohibit mechanized access, meaning hunters heading into that quarter of the unit's acreage should plan on foot or stock-based travel only. Combined with the unit's extreme elevation range — from 6,169 feet at the low end to 14,036 feet at the high end — this is a unit that rewards physical fitness and backcountry competence. The high country above treeline offers classic alpine basin hunting for elk pushed up by pressure or seeking thermal relief, while the lower elevations transition through timber and sage that hold elk earlier in the season and during weather-driven movement.

Given that Colorado does not impose the nonresident wilderness guide requirement found in some other states, nonresident hunters are free to hunt Unit 86's wilderness acreage unguided if they're prepared for the physical and logistical demands of that terrain. Hunters should use mapping tools — HuntPilot's platform includes public land overlays that are useful for identifying where that 58% public land actually sits relative to access points and wilderness boundaries — to plan routes before ever setting foot in the unit.

The terrain diversity here means scouting strategy should be elevation-dependent: lower-elevation timber and sage transition zones for early movement and access-friendly hunting, and higher alpine basins for hunters willing to pack in deeper for more secluded elk that have pushed away from pressure.

How to Apply

Because Unit 86 has no general season, every elk hunt in this unit — including tags for antlered and either-sex animals — is allocated through Colorado's limited-quota draw system. There is no over-the-counter option here; hunters must apply and be selected in the draw to hunt elk in this unit at all.

Colorado's draw system uses true preference points, meaning hunters who accumulate the highest point totals over multiple years draw ahead of those with fewer points on point-limited hunts. This is not a weighted lottery — it functions as a genuine preference system where a sufficiently high point total can effectively guarantee a tag on many hunts, depending on demand for that specific hunt code. Residents and nonresidents apply through separate pools, and nonresidents should expect to need a more substantial point investment than residents for the same hunt given typically higher demand relative to nonresident quota allocations.

Hunters new to the Colorado system should understand that points are hunt-code specific in terms of competitiveness — some hunt codes within Unit 86 will require more points than others depending on demand. When a hunter successfully draws a tag using accumulated points, those points are spent and the hunter starts rebuilding from zero for future applications in that species category.

Application dates, fees, and current draw odds for specific hunt codes in Unit 86 change every cycle. For the most current deadlines, fees, and draw statistics, see HuntPilot's Colorado state page at /states/CO, or consult Colorado Parks and Wildlife's published draw recommendations directly.

Frequently Asked Questions

What is the terrain like in Colorado Unit 86? Unit 86 spans an extreme elevation range from 6,169 to 14,036 feet, encompassing everything from lower-elevation sage and timber transition country to true high-alpine basins above treeline. With 25% of the unit designated wilderness, a significant portion requires foot or stock access only. The terrain diversity means elk can be found across multiple elevation bands depending on time of year, weather, and hunting pressure.

What is harvest success like in Unit 86? Recent harvest success has ranged from 12% to 22% over the last four recorded seasons. The most recent data year, 2025, showed the strongest results at 22% success with 274 elk harvested among 1,230 hunters — a notable improvement over the 12-15% success rates seen in 2022 through 2024, years that also saw significantly higher hunter numbers in the field.

How big are the elk in Unit 86? Trophy history for the counties overlapping this unit is limited, and the average bull:cow ratio of 18:100 recorded across six survey years (2018-2024) suggests fewer bulls are reaching mature, older-age classes compared to units with more favorable bull escapement ratios. Hunters should expect a realistic shot at a representative bull rather than plan around trophy-class expectations.

Is Unit 86 worth applying for? For hunters prioritizing a legitimate limited-quota elk hunt with solid public access (58%), meaningful wilderness character (25%), and improving harvest success (up to 22% in 2025), yes — it's a reasonable unit to target. For hunters whose primary goal is a trophy-class bull, the limited trophy history and low bull:cow ratio suggest looking elsewhere may better match that specific goal.

Does Unit 86 have an over-the-counter elk option? No. Unit 86 has no general season for elk — every hunt, including tags for antlered and either-sex animals, is allocated exclusively through Colorado's limited-quota draw system. Hunters must apply and be selected to hunt elk in this unit.
