Colorado Unit S47 Bighorn Sheep Hunting Guide

Colorado Unit S47 is a limited-quota bighorn sheep unit covering 265,249 acres in some of the state's rugged high-country terrain, with elevations ranging from 6,348 feet up to 11,040 feet. For hunters researching this unit, the most important fact to understand up front is that there is no general season here — every bighorn sheep hunt in S47 is a limited-quota draw hunt, administered entirely through Colorado's lottery system. This is a low-volume, high-stakes unit where a handful of tags are issued each year, and drawing one often represents the culmination of a decade or more of point accumulation.

Bighorn sheep hunting in Colorado is unlike almost any other big game pursuit in the Rockies. Tag numbers are intentionally kept minimal to protect herd health, which means data on units like S47 is thin by design — a handful of hunters per year, not hundreds. That scarcity is also what makes a drawn tag here so valuable: hunters who draw S47 are stepping into one of the most exclusive hunts available in the state.

Herd Health & Harvest Success

Harvest data for S47 reflects the reality of a tightly managed bighorn sheep unit: small hunter numbers and extremely high success rates. In 2025, all 3 hunters who drew tags harvested a ram, a 100% success rate. That mirrors prior seasons closely — 2024 saw 6 hunters and 6 harvests, 2023 saw 6 hunters and 6 harvests, 2022 had 4 hunters and 4 harvests, 2021 had 4 hunters and 4 harvests, and 2019 recorded 2 hunters and 2 harvests. Every single recorded season shows 100% success.

This consistency is worth unpacking rather than just celebrating. Colorado's bighorn sheep tags are issued in very small numbers, and the state's wildlife managers, combined with hunters who often spend years or decades building points for a single tag, tend to produce extremely prepared, well-scouted hunters who are willing to put in the time needed to connect. A 100% success rate across six consecutive recorded seasons is not unusual for Colorado sheep units — it reflects the nature of the hunt (low tag numbers, highly motivated hunters, often extended season windows) rather than suggesting the hunting itself is easy. Rams in alpine terrain still require careful glassing, physical conditioning, and patience to close the distance on comparable animals.

For hunters, the practical takeaway is this: if a hunter draws a tag in S47, history suggests the odds of eventually connecting on a ram are very strong, provided they put in the scouting time and physical preparation the terrain demands.

Trophy Quality

Trophy records tied to the counties overlapping Unit S47 show a moderate history of trophy-class rams. This doesn't place S47 among Colorado's elite handful of units known for producing record-book entries year after year, but it also isn't a unit lacking trophy pedigree. Hunters drawing this tag should expect a realistic chance at a mature, quality ram, with the possibility — not the guarantee — of an animal that reaches trophy-class dimensions.

It's worth noting that trophy-book entries are logged at the county level, not the unit level, so the records associated with S47's overlapping counties are shared with neighboring units as well — the specific animals attributed to those entries may have been taken anywhere within that broader county footprint. Hunters should treat this as a general indicator of regional trophy potential rather than a guarantee specific to S47's boundaries.

Given the moderate trophy history and very high historical success rates, S47 looks like a unit where most hunters who draw will fill their tag, with trophy quality running from solid, mature rams up through occasional standout animals — a profile consistent with many mid-tier Colorado bighorn units rather than the handful of units that dominate the state's record books.

Access & Terrain

S47 spans a wide elevation gradient, from 6,348 feet at its lowest to 11,040 feet at its highest points, putting much of the huntable sheep habitat well into alpine and subalpine terrain. Bighorn sheep in Colorado typically favor the steep, rocky, high-elevation terrain found at the top end of that range, so hunters should expect demanding physical conditions — steep ascents, technical footing, and thin air at altitude.

Public land makes up 76% of the unit's 265,249 acres, which is a strong number for Colorado and means the large majority of S47 is accessible without needing private landowner permission. This is a meaningful advantage for DIY hunters: most of the unit's terrain, including likely sheep habitat in the higher-elevation public holdings, should be reachable through public access points.

The unit carries no designated wilderness acreage in the available data, which means hunters won't face wilderness-specific travel restrictions here, though the elevation and ruggedness of bighorn habitat will still demand pack-in style hunting in many of the better basins and ridgelines. Hunters should plan on serious physical preparation regardless of wilderness designation — bighorn country punishes hunters who show up out of shape, full stop.

HuntPilot Analysis — Is S47 Worth Applying For?

For hunters evaluating whether to put in for S47, the data from HuntPilot points to a clear profile: this is a unit where drawing the tag is the hard part, and successfully filling it is the comparatively easier part. With 100% harvest success recorded across every available season from 2019 through 2025 — admittedly on small sample sizes of 2 to 6 hunters per year — hunters who do draw S47 have historically gone home with a ram.

The moderate trophy history means S47 isn't positioned as a unit chasing record-book headlines, but it also isn't a unit where trophy potential is absent. Hunters should view this as a legitimate opportunity to take a quality, mature ram in genuinely demanding, scenic high-country terrain, with 76% public land ensuring access isn't a major limiting factor.

The honest assessment: S47 is worth applying for if a hunter is building points for bighorn sheep and wants a unit with a strong track record of converting drawn tags into harvested rams, reasonable public access, and solid (if not flagship) trophy potential. Hunters chasing a shot at one of Colorado's true record-book units may want to compare S47 against units with deeper trophy pedigrees, but for a well-rounded, high-success bighorn hunt on mostly public ground, S47 checks the right boxes.

How to Apply

Colorado bighorn sheep tags are allocated entirely through the state's limited-quota draw system — there is no over-the-counter or general-season option for this species in S47 or anywhere else in Colorado. Both residents and nonresidents must apply through the same centralized draw, though Colorado maintains separate resident and nonresident allocation structures, and nonresidents will generally face steeper competition for the same tags.

Colorado's system is a true preference-point structure for bighorn sheep: the hunters holding the most weighted points are prioritized in the draw, meaning a high enough point total can functionally guarantee a tag over time in units where demand allows. Points are specific to the species, so hunters applying for bighorn sheep should expect to compound their position year over year as they continue to apply, assuming they don't draw before accumulating a top-tier point total. It's worth noting that a successful draw consumes those accumulated points — a hunter who finally draws S47 will restart their point total near zero for future bighorn applications.

Because Colorado's draw structure, point requirements, and application windows shift from year to year, hunters should not rely on fixed figures when planning their application strategy.

Frequently Asked Questions

What is the terrain like in Colorado Unit S47? S47 covers elevations from 6,348 feet up to 11,040 feet, meaning hunters should expect a mix of lower-elevation approach terrain transitioning into steep, rocky alpine and subalpine habitat where bighorn sheep are most commonly found. With 76% of the unit's 265,249 acres in public ownership, access to this terrain is generally strong, though the physical demands of hunting at elevation in steep country should not be underestimated.

What is harvest success like in Unit S47? Harvest success has been exceptionally high in every recorded season. From 2019 through 2025, S47 posted 100% success rates across all years with available data — including 6 hunters and 6 harvests in both 2024 and 2023, and 3 for 3 in 2025. These are small sample sizes typical of limited-quota bighorn sheep units, but the trend is consistent and suggests that hunters who draw a tag here have historically had strong odds of filling it.

How big are the bighorn sheep in Unit S47? Trophy records tied to the counties overlapping S47 show a moderate history of trophy-class rams, suggesting realistic potential for a mature, quality animal without placing S47 among Colorado's top-tier trophy sheep units. Because record-book entries are tracked at the county level and shared with neighboring units, hunters should treat this as a regional indicator rather than a unit-specific guarantee.

Is Unit S47 worth applying for? Based on available data, yes — particularly for hunters who prioritize a strong likelihood of filling the tag once drawn. The unit's 100% historical success rate, majority public land access at 76%, and moderate trophy potential combine to make it a solid, realistic bighorn sheep option, even if it isn't among the handful of units known for producing the state's biggest rams.

Is Unit S47 a good unit for DIY hunters? With 76% public land across 265,249 acres and no wilderness-designation restrictions in the data, DIY hunters have a strong access foundation in S47. That said, the elevation range up to 11,040 feet means physical conditioning and technical mountain hunting skills are essential regardless of land ownership status.
