Colorado Unit 681 Elk Hunting Guide

Colorado Unit 681 is a limited-quota elk unit that draws attention from hunters searching for public-land opportunity in high-elevation country. With 92% public land across 284,294 acres and elevations ranging from 7,675 feet to 13,246 feet, this unit offers the kind of vertical, rugged terrain that defines backcountry elk hunting in the Colorado high country. Every elk hunt in this unit is limited-quota — there is no general season here, which shapes how hunters should think about tag strategy from the outset.

For hunters comparing units on HuntPilot, Unit 681 stands out as a data point worth understanding in detail: a unit with strong public access, real elevation relief, and a harvest track record that's worth examining honestly before committing a season — and possibly years of point accumulation — to hunting it.

Hunt Structure: A Limited-Quota Unit Start to Finish

Unlike many Colorado elk units that pair an over-the-counter general season for bulls with draw-only antlerless tags, Unit 681 has no general season at all. Every hunt here — including hunts for antlered and either-sex animals — is limited-quota and allocated through the draw. This is an important distinction for hunters used to units where a general tag is available without applying. In Unit 681, there is no walk-in option; hunters must draw a tag before they can hunt, regardless of which sex or hunt type they're after.

This structure typically means more controlled hunter densities on the ground compared to over-the-counter units, but it also means access to this unit is entirely dependent on the draw. Hunters should treat Unit 681 as a unit to plan around years in advance if targeting harder-to-draw hunt codes, while also recognizing that limited-quota structures generally spread hunting pressure more evenly across the season than OTC units do.

Access & Terrain

Unit 681 offers exceptional public land access, with 92% of its 284,294 acres open to public hunting. That ratio puts the burden of finding elk squarely on scouting and legwork rather than negotiating private land access, which is a meaningful advantage for DIY-minded hunters.

The elevation range — 7,675 feet at the low end to 13,246 feet at the highest points — tells the real story of this unit's character. This is big vertical country, spanning from lower foothill and valley terrain up into alpine basins above treeline. Elk in country like this typically use elevation seasonally: lower slopes and timbered draws early, and higher basins and ridgelines as temperatures rise or hunting pressure builds. Hunters willing to gain elevation and get away from easy access points generally find less pressured animals, particularly in a unit with this much vertical relief to work with.

No wilderness acreage is listed for this unit, which means hunters aren't dealing with the additional access restrictions or stock/permit requirements sometimes associated with formally designated wilderness areas. That said, terrain reaching over 13,000 feet is serious high-alpine country regardless of wilderness designation, and hunters should be prepared for thin air, unpredictable weather, and physically demanding travel — conditions echoed in hunter reports describing dramatic swings between hot, dry, dusty days and cold, wet, frigid ones within the same trip.

With 92% public land, this unit is genuinely DIY-friendly from an access standpoint. The limiting factor for most hunters here won't be finding a place to hunt — it will be the physical demands of covering ground at elevation and finding elk that have retreated into remote, high-effort terrain away from roads and trailheads.

Harvest Success Rates

Harvest data for Unit 681 spans four recent seasons and shows both the opportunity and the difficulty inherent in this kind of high-elevation, limited-quota unit.

• 2025: 5,069 hunters, 547 elk harvested, 11% success
• 2024: 3,038 hunters, 306 elk harvested, 10% success
• 2023: 2,995 hunters, 212 elk harvested, 7% success
• 2022: 2,806 hunters, 255 elk harvested, 9% success

Success rates have hovered in the 7-11% range across these four years, which is consistent with a physically demanding, high-elevation unit rather than an easy-access, high-density elk area. Notably, hunter numbers jumped significantly in 2025 — from roughly 2,800-3,000 hunters in the prior three years to over 5,000 — while success rate actually improved slightly to 11%, the best mark in the four-year window. That's a meaningful data point: more hunters afield didn't dilute success, suggesting the unit's elk population and huntable habitat can absorb additional pressure without a proportional drop in harvest efficiency.

Still, single-digit-to-low-double-digit success rates mean the majority of hunters who draw a tag in Unit 681 will go home without an elk. This is normal for rugged, high-elevation limited-quota units, but hunters should set expectations accordingly and invest in scouting, physical conditioning, and flexibility in where they hunt within the unit.

Herd Health & Population Trends

Wildlife survey data collected across six survey years from 2018 to 2024 shows an average bull-to-cow ratio of 20:100 for Unit 681. This is a low ratio relative to many Colorado elk units, and it's a figure hunters should weigh carefully when evaluating trophy potential and bull availability.

A 20:100 ratio, sustained across six years of surveys rather than a single anomalous count, suggests this is a real, consistent characteristic of the herd rather than a survey artifact. Low bull-to-cow ratios typically indicate either significant hunting pressure on bulls, tough winter survival conditions at elevation, or some combination of both. For hunters, this translates to fewer mature bulls per cow in the population, which can mean more scouting effort and patience are required to locate a shooter bull versus units with richer bull ratios.

This data point should factor directly into expectations: Unit 681 is not a unit where bulls are so abundant that hunters can expect to see multiple mature animals daily. Success will depend heavily on covering remote, high-elevation terrain where bulls that have survived hunting pressure tend to retreat.

Trophy Quality

Trophy record data for the counties overlapping Unit 681 shows a limited history of trophy-class entries. This doesn't mean big bulls don't exist in this unit, but it does mean the record book doesn't currently reflect a strong or consistent pattern of trophy production from this area compared to some of Colorado's more storied elk units.

Given the low bull-to-cow ratio documented in the survey data and the limited trophy history, hunters targeting Unit 681 should approach it primarily as an opportunity and experience-focused hunt in genuinely wild, high-elevation country rather than a unit chosen specifically for trophy potential. That's not a knock on the unit — it's simply an honest read of the data. Hunters chasing a genuine record-class bull may want to weigh this unit against others with deeper trophy pedigrees, while hunters who prioritize public land access, rugged terrain, and a real backcountry experience will find plenty to like here.

HuntPilot Analysis: Is Unit 681 Worth Applying For?

Unit 681 presents a mixed but honest picture. On the positive side: 92% public land access is exceptional, giving DIY hunters the freedom to hunt extensively without needing to negotiate private land permission. The elevation range offers serious backcountry terrain for hunters willing to put in physical effort, and the 2025 harvest data — showing improved success even as hunter numbers nearly doubled — suggests a herd base that can support increased pressure without collapsing success rates.

On the other hand, hunters need to go in with realistic expectations. Success rates in the 7-11% range mean the majority of tag holders won't fill their tag. The 20:100 bull-to-cow ratio, consistent across six years of surveys, points to a lean bull population relative to cows, and the limited trophy record history in the surrounding counties confirms this isn't a unit with a strong pedigree of record-class bulls.

For hunters who value public land access, want to hunt genuinely rugged, high-elevation country, and are comfortable working hard for a modest but real chance at success, Unit 681 is a legitimate option. For hunters whose primary goal is a shot at a trophy-class bull or the highest possible harvest odds, this data suggests looking at other units with stronger bull ratios and deeper trophy histories may be the better play. As always, the numbers here — sourced from HuntPilot's unit data — should guide that decision rather than unit reputation alone.

How to Apply

Because Unit 681 has no general season, hunters must draw a limited-quota tag through Colorado's draw system to hunt elk here — there's no over-the-counter fallback option for this unit. Colorado's draw process differs for residents and nonresidents, and preference point accumulation plays a role in draw competitiveness for many hunt codes in this unit.

Colorado runs a true preference system for elk, meaning hunters with the highest point totals draw before those with fewer points — at a sufficient point level, a draw can be functionally guaranteed on many hunt codes. This is different from a weighted lottery, so understanding current point distributions and draw data for the specific hunt codes available in Unit 681 is essential before applying. Resident and nonresident applicants are also subject to different quota allocations, which affects how competitive each hunt code is depending on residency.

Application dates, fees, and current draw odds for Unit 681 change every cycle. For up-to-date deadlines, costs, and draw statistics broken down by hunt code and point level, see HuntPilot's Colorado state page for the most current information before planning your application strategy.

Frequently Asked Questions

What is the terrain like in Unit 681? Unit 681 spans a dramatic elevation range from 7,675 feet to 13,246 feet, encompassing everything from lower valley and foothill terrain to high alpine basins above treeline. With 92% public land, hunters have wide access to this terrain, but the vertical relief means physical conditioning and elevation acclimation are important considerations. No wilderness acreage is designated in this unit.

What is harvest success like in Unit 681? Recent harvest data shows success rates ranging from 7% to 11% across 2022-2025, with the most recent 2025 season posting 547 elk harvested among 5,069 hunters for an 11% success rate. These numbers reflect a genuinely challenging, high-elevation hunt rather than an easy-access unit.

How big are the elk in Unit 681? Trophy record data for the counties overlapping this unit shows a limited history of trophy-class entries, and survey data shows a below-average bull-to-cow ratio of 20:100 across six years of surveys. This suggests hunters should approach the unit with realistic expectations about bull quality and abundance rather than targeting it specifically for trophy potential.

Is Unit 681 worth applying for? It depends on hunter priorities. The unit offers excellent public land access (92%) and serious backcountry terrain, and 2025 data shows the unit can absorb more hunting pressure while maintaining or improving success rates. However, single-digit-to-low-double-digit success rates and a lean bull-to-cow ratio mean this is better suited to hunters prioritizing wilderness-style experience and opportunity over trophy odds or high success guarantees.

Is Unit 681 a good unit for DIY public land elk hunting? Yes, from an access standpoint — 92% public land is well above average and removes most private-land access barriers. The tradeoff is that success depends heavily on physical effort and the ability to hunt remote, high-elevation terrain, since the harvest and survey data both point to a unit where finding elk requires real legwork rather than easy road-accessible hunting.
