Colorado Unit S09 Bighorn Sheep Hunting Guide
A Rare Tag in High Country Colorado
Colorado Unit S09 bighorn sheep hunting represents one of the most coveted draw opportunities in the state. Spanning 730,133 acres of rugged terrain with elevations ranging from 6,993 to 14,249 feet, S09 encompasses the kind of dramatic alpine and subalpine landscape that defines classic Rocky Mountain sheep country. With 63% public land, hunters have meaningful access to the unit, though the 15% wilderness designation means a significant portion of the most productive terrain is remote, physically demanding, and requires serious logistical planning.
Bighorn sheep tags are among the rarest permits issued anywhere in the western United States, and Colorado is no exception. Unit S09 issues a limited number of tags annually across its draw pools — this is a multi-year point investment for nearly all applicants regardless of residency. The hunters who do draw describe country that is as unforgiving as it is spectacular, with steep cliff faces, narrow ledges, and exposed ridgelines that demand physical fitness and solid mountain experience. What makes S09 worth researching is that recent harvest data shows consistent performance when hunters do get into the field.
This guide breaks down everything researchers need to know about S09 bighorn sheep hunting — from harvest trends and trophy potential to the 2026 application calendar and honest cost estimates.
Harvest Success Rates
The harvest data for Colorado Unit S09 tells a story of steady improvement after a difficult stretch in the early part of the decade.
The most difficult years on record in this dataset were 2020 and 2021–2022. In 2020, only 4 hunters pursued rams in the unit, and just 1 was successful — a 25% success rate that likely reflects access or weather challenges. The following two years were nearly as rough: 2021 saw 36 hunters with 14 harvested (39% success), and 2022 produced the same 14 harvests from 42 hunters (33% success). By any measure, those years were hard on hunters who had waited years to draw this tag.
The rebound since then has been dramatic:
- 2023: 46 hunters, 28 harvested — 61% success
- 2024: 42 hunters, 30 harvested — 71% success
- 2025: 22 hunters, 16 harvested — 73% success
The 2025 figure deserves some context — with only 22 hunters in the field compared to 42–46 in the prior two years, the smaller sample size should be noted. But the directional trend from 2023 through 2025 is clear: success rates have climbed steadily, and the 71–73% range in 2024–2025 is strong performance for a big game sheep hunt anywhere. For comparison, bighorn sheep success rates in many western units hover in the 50–65% range, making S09's recent numbers notable.
The multi-year pattern suggests that the herd supported improved hunter success in recent seasons after the lean years of 2020–2022. Hunters drawing this tag in 2026 have reason to be optimistic based on recent field performance.
Trophy Quality
The counties overlapping Unit S09 carry a limited trophy history based on available record data. Hunters targeting S09 specifically for record-book potential should enter with measured expectations — trophy-class rams have been taken from this area, but trophy production is not what distinguishes this unit among Colorado's most prestigious sheep draws.
This is an important calibration for applicants who have spent years accumulating points. The tag is genuinely rare and the hunting experience in S09's high alpine terrain is exceptional by any standard. But hunters primarily motivated by record-book potential may want to compare S09 against other Colorado sheep units before committing their points.
For most hunters, drawing any Colorado bighorn sheep tag is itself the achievement of a lifetime. S09 offers a legitimate, wild, fair-chase experience in serious mountain country — that is worth a great deal regardless of trophy ceiling.
Herd Health & Population Trends
Direct wildlife survey data is not available in the structured dataset for this unit, so specific bull:ewe ratios or lamb recruitment figures cannot be cited here. However, the harvest trajectory offers indirect insight.
The improvement in success rates from 2022 (33%) to 2024–2025 (71–73%) is consistent with a herd that either rebounded from a difficult period or experienced improved conditions that made rams more accessible and visible to hunters. The sustained performance across three consecutive years (2023–2025) strengthens that interpretation — this is not a one-year statistical anomaly.
That said, tag quotas across S09's draw pools have not increased with the harvest improvement. The quota data for 2024–2026 shows stable or slightly declining allocations in two of the three tracked hunt types, with one seeing a cut from 4 tags to 3 tags between 2025 and 2026. Managers clearly remain conservative with this herd, which is appropriate for a species as slow-reproducing and sensitive to overharvest as bighorn sheep.
Hunters should check Colorado Parks and Wildlife's annual herd management reports for current population data specific to S09.
Access & Terrain
At 730,133 total acres with 63% public land, Unit S09 provides substantial public access — roughly 460,000 acres hunters can legally access without landowner permission. That is a genuine strength for DIY hunters willing to do the work.
However, the 15% wilderness designation within the unit means that a meaningful portion of the most productive, least-pressured terrain requires a serious backcountry commitment. Wilderness sheep country in Colorado typically means multi-day pack-in hunts, spike camps, and the ability to cover miles of technical terrain on foot. There are no mechanized access options in designated wilderness — horses are the primary alternative to foot travel for hunters bringing heavy camp gear.
Important note for nonresident hunters: Colorado does not have Wyoming's guide requirement for wilderness. Nonresidents in Colorado can hunt S09's wilderness areas without hiring a licensed outfitter. That said, the physical demands of hunting sheep at 10,000–14,000 feet in wilderness terrain are significant. Many hunters — resident and nonresident alike — choose to hire a guide for logistical support and to maximize the experience of what may be a once-in-a-lifetime tag.
The non-wilderness portions of S09 offer more accessible terrain in the lower elevations (near 7,000 feet), but bighorn sheep in Colorado typically concentrate in steep, rocky terrain well above treeline. The bulk of productive sheep habitat in S09 sits at elevations where physical fitness and altitude acclimatization are not optional.
Hunters new to high-altitude sheep hunting should plan for multiple acclimatization days before the physically demanding work of glassing and stalking steep terrain.
HuntPilot Analysis: Is S09 Worth Applying For?
Here is an honest assessment based on the available data:
The case for applying: Recent harvest success rates of 61–73% over three consecutive years are genuinely strong. The unit has 63% public land and offers DIY access without the mandatory guide requirement that burdens nonresidents in Wyoming. The high alpine terrain from 7,000 to 14,249 feet is classic bighorn country. For hunters who simply want to hunt bighorn sheep in Colorado on a legitimate, fair-chase tag with solid recent success rates, S09 is a credible draw target.
The case for caution: Trophy history in the counties overlapping S09 is limited — hunters prioritizing record-book potential should examine alternative units. Tag allocations are extremely tight, and the point commitment required to draw is substantial. The 2026 quota data shows one hunt type was cut from 4 to 3 tags, which will not help draw odds. Physical demands are serious — 14,249-foot terrain with 15% wilderness is not a casual undertaking.
Bottom line: S09 is a legitimate Colorado bighorn sheep opportunity with strong recent harvest performance and good public land access. It is not the state's premier trophy unit based on available records, but for hunters whose primary goal is to hunt wild Colorado bighorn sheep in spectacular mountain country — and who have the points and physical fitness to compete — S09 deserves serious consideration.

Frequently Asked Questions
What is the terrain like in Colorado Unit S09?
Unit S09 covers 730,133 acres of extremely varied terrain, ranging from roughly 7,000 feet in the lower drainages to 14,249 feet at the highest peaks. The majority of productive bighorn sheep habitat sits in steep, rocky alpine and subalpine zones well above treeline. Hunters should expect cliff bands, exposed ridgelines, talus fields, and loose shale common to Colorado's high-country sheep units. Approximately 15% of the unit is designated wilderness, making much of the best sheep country accessible only on foot or by horse over multiple days. Physical fitness and altitude acclimatization are essential.
What is the harvest success rate in Colorado Unit S09 bighorn sheep hunting?
Recent data shows strong improvement in S09 harvest rates. Success was 61% in 2023, 71% in 2024, and 73% in 2025. That three-year trend follows a difficult stretch from 2020–2022 when success rates dropped as low as 25–33%. The recent performance of 70%+ success is above average for a western bighorn sheep unit and suggests hunters who draw the tag are finding animals in accessible conditions.
How big are the bighorn sheep in Colorado Unit S09?
Trophy data for the counties overlapping S09 indicates limited trophy history. Trophy-class rams have been taken from this area, but the unit does not rank among Colorado's premier record-book destinations. Hunters whose primary motivation is maximum trophy potential should compare S09 against other Colorado sheep units before committing preference points. That said, drawing any Colorado bighorn sheep tag and hunting wild rams in alpine terrain above 12,000 feet is a legitimate once-in-a-lifetime experience regardless of trophy ceiling.
Is Colorado Unit S09 worth applying for?
For hunters with sufficient preference points and the physical conditioning to pursue bighorn sheep in demanding high-altitude terrain, S09 is worth serious consideration. The unit has 63% public land, strong recent harvest success (71–73% in 2024–2025), and no mandatory guide requirement for nonresidents. The primary limitations are limited trophy history in overlapping counties and extremely tight tag allocations. Hunters should visit the HuntPilot Colorado page to review current draw odds for their specific residency and point level before applying.
Can nonresidents hunt Unit S09 bighorn sheep without a guide?
Yes. Unlike Wyoming, Colorado does not require nonresident hunters to hire a licensed outfitter to hunt in designated wilderness areas. Nonresidents can legally pursue bighorn sheep throughout S09, including its wilderness portions, on a DIY basis. However, the physical demands of multi-day pack-in hunting at elevations up to 14,249 feet are substantial. Many hunters — regardless of residency — choose guided support for logistical reasons on a hunt of this significance and difficulty, but it is not a legal requirement in Colorado.
