Colorado Unit S75 Bighorn Sheep Hunting Guide

Colorado Unit S75 is one of the most coveted limited-quota bighorn sheep units in the state, drawing serious interest from sheep hunters willing to invest years — sometimes decades — of points for a shot at a tag. With a tiny number of permits issued annually and a reputation among sheep hunters as a destination unit, S75 represents the kind of once-in-a-lifetime opportunity that defines western bighorn sheep hunting. This article breaks down what the data actually shows about this unit, so hunters can decide whether it belongs on their application list.

Spanning 449,002 acres with an elevation range of 4,713 to 9,049 feet, S75 offers a mix of lower-elevation approach terrain and high alpine basins typical of Colorado bighorn country. Public land makes up 63% of the unit, giving hunters a solid base of accessible ground to work with, though hunters should expect to encounter private inholdings as well. There is no designated wilderness acreage reported for this unit, which means access logistics are somewhat more straightforward than in some of Colorado's wilderness-heavy sheep units, though the terrain itself should never be underestimated.

Every hunt opportunity in S75 is limited-quota — there is no general season here. This is a draw-only unit, and every tag issued, whether for a mature ram or otherwise, comes through Colorado's limited licensing system. Hunters who draw a tag in S75 are stepping into one of the most exclusive drawers in the state's big game program.

HuntPilot Analysis: Is S75 Worth Applying For?

The honest answer: yes, if a hunter is playing the long game and has the patience for a true points-investment strategy. S75 is not a unit that rewards impatience, and it's not a unit that casual applicants should expect to draw in a handful of years. But for hunters serious about pursuing a Colorado bighorn, S75 checks the boxes that matter most — consistent, high-percentage harvest success once drawn, and a qualitative trophy history that places it among Colorado's better-regarded sheep units.

Harvest data pulled from HuntPilot shows that S75 has produced 100% hunter success in every recent year with reported data: 3 for 3 in 2025, 4 for 4 in 2024, 4 for 4 in 2023, 4 for 4 in 2022, 2 for 2 in 2021, and 1 for 1 in 2019. That's a perfect harvest record across six recorded seasons. For context, bighorn sheep hunts nationwide are famous for near-universal success rates simply because so few tags are issued and hunters who draw dedicate enormous time, money, and scouting effort to the hunt — but a flawless multi-year track record like this still speaks to a huntable, accessible ram population and hunters who come prepared.

The trade-off, as with virtually every bighorn sheep unit in the West, is that tag numbers are minuscule. The harvest totals themselves tell the story: this unit issues only a handful of tags per year, meaning the hunter pool is small and every drawn tag represents an enormous investment of preference points for most nonresident and even many resident applicants. This is not a unit a hunter stumbles into — it's a unit a hunter builds a multi-year, sometimes multi-decade, strategy around.

Trophy history for the counties overlapping S75 shows a moderate trophy record, meaning the area has produced some record-class rams over time but isn't necessarily at the very top tier of Colorado's sheep units in terms of sheer volume of trophy entries. Hunters should view S75 as a legitimate shot at a mature, representative Colorado bighorn ram rather than a guaranteed shot at a record-book animal. That said, moderate trophy history combined with perfect recent harvest success is a solid combination — it suggests a healthy, mature ram population that hunters are successfully locating and harvesting year after year.

For hunters weighing S75 against other Colorado sheep units, the unit's biggest selling points are its consistency and its accessible public land base. The biggest consideration is the reality of the draw itself: this is a long-term points play, not a quick-draw unit.

Harvest Success Rates

S75's harvest numbers are remarkably consistent for a bighorn sheep unit:

• 2025: 3 hunters, 3 harvested — 100% success
• 2024: 4 hunters, 4 harvested — 100% success
• 2023: 4 hunters, 4 harvested — 100% success
• 2022: 4 hunters, 4 harvested — 100% success
• 2021: 2 hunters, 2 harvested — 100% success
• 2019: 1 hunter, 1 harvested — 100% success

Across every reported year, every single hunter who drew a tag in S75 connected on a ram. This kind of harvest consistency is common in bighorn sheep units generally — the extremely low tag numbers mean hunters who draw are typically seasoned, well-prepared, and often supported by scouting networks, guides, or years of unit-specific knowledge gathered while waiting out the draw. Still, a 100% success rate sustained across six consecutive reporting years is a strong indicator that rams are both present and locatable for hunters willing to put in the physical effort this terrain demands.

It's worth noting that the sample sizes here are small — 1 to 4 hunters per year — which is standard for limited-quota sheep units. A single unsuccessful hunt in a future season wouldn't be unusual or alarming given these small numbers, but the multi-year trend of perfect success is the more meaningful signal, and it has held steady since at least 2019.

Trophy Quality

Trophy records from the counties overlapping Unit S75 show a moderate history of record-book entries. This places S75 in a middle tier among Colorado's bighorn units — not among the state's top-producing trophy counties, but with a real and ongoing history of mature rams being taken from the area. Hunters should keep in mind that trophy-record data is logged at the county level, meaning entries attributed to the broader region may have come from animals taken in S75 or in neighboring units that share the same county boundaries. The practical takeaway for hunters is that S75 offers a genuine chance at a mature, representative Colorado ram, with the occasional exceptional animal, rather than a unit defined primarily by chasing record-book scores.

Given the unit's perfect recent harvest success combined with only moderate trophy density, S75 looks like a unit where hunters are successfully taking available rams rather than passing on everything but the biggest ram in the drainage. That's a meaningful distinction for hunters setting expectations: this is a quality hunt for a mature bighorn, not necessarily a unit to bank on for chasing an all-time-caliber trophy.

Access & Terrain

S75 covers 449,002 acres with elevations ranging from 4,713 feet up to 9,049 feet — a substantial vertical range that puts hunters into everything from lower foothill terrain to high alpine basins typical of Colorado bighorn habitat. This kind of elevation spread means physical conditioning and acclimatization matter: hunters drawing this tag should expect demanding terrain and should plan scouting trips accordingly to understand where rams are using the landscape at different points in the hunt period.

Public land accounts for 63% of the unit, which gives hunters a workable base for access without needing to rely heavily on private landowner permission. That said, with over a third of the unit in private hands, hunters should still expect some patchwork land ownership and should confirm boundaries carefully before committing to a specific drainage or basin. No wilderness acreage is reported for S75, so hunters won't be dealing with the added logistical complications — stock use restrictions, mechanized-access limits — that come with designated wilderness in some other Colorado sheep units.

Given the rugged, high-elevation character typical of bighorn sheep terrain in Colorado, hunters should plan on physically demanding glassing and stalking conditions regardless of exact drainage. HuntPilot's mapping tools, including public land overlays, can help hunters identify exactly where the 63% public land lies relative to access points before investing in a scouting trip.

How to Apply

S75 is a 100% limited-quota unit — there is no general season path to a tag here. Every hunter who wants to hunt bighorn sheep in S75 must apply through Colorado's draw system, and that holds true for both residents and nonresidents.

Colorado's big game draw operates on a true preference point system for sheep: the state's highest point holders are awarded tags before the remaining tags go into a random pool, and a high enough point total can position an applicant for a near-certain draw over time. This is fundamentally different from a weighted lottery — the preference system rewards patience, and the points a hunter accumulates by applying (and not drawing) in prior years carry forward and improve their position in future draws. Residents and nonresidents apply through separate pools with separate point structures, so hunters should check their own residency category when evaluating their realistic draw timeline.

Because S75 issues so few tags per year, hunters should expect this to be a multi-year, often multi-decade points strategy rather than a short-term goal. Hunters serious about this unit should begin building points as early as possible and should revisit their strategy annually as point distributions shift.

Application dates and fees change every cycle. For the current deadlines, fees, and draw odds, hunters should check HuntPilot's Colorado page at /states/CO for the most current information before applying.

What is the terrain like in Colorado Unit S75? S75 spans a wide elevation range from 4,713 to 9,049 feet, encompassing everything from lower foothill approach terrain to high alpine basins characteristic of Colorado bighorn sheep habitat. With 449,002 total acres and no designated wilderness, hunters face rugged, physically demanding country but without the added stock-use and access restrictions that come with wilderness designations in some other Colorado sheep units.

What is harvest success like in Unit S75? Harvest success in S75 has been exceptional and consistent. Every reported year from 2019 through 2025 shows a 100% harvest success rate, including 4 for 4 in 2024, 4 for 4 in 2023, and 4 for 4 in 2022. Hunter numbers are small each year (1 to 4 hunters), which is typical for a limited-quota sheep unit, but the consistency of success across multiple years is a strong positive signal for anyone who eventually draws a tag here.

How big are the bighorn sheep in Unit S75? Trophy records for the counties overlapping S75 show a moderate history of record-book entries, suggesting hunters have a real chance at a mature, representative Colorado ram with occasional exceptional animals, though the unit isn't among the state's top trophy producers by volume of entries. Hunters should set expectations around harvesting a solid mature ram rather than specifically targeting an all-time-class trophy.

Is Unit S75 worth applying for? Based on the available data, yes — particularly for hunters prepared to commit to a long-term points strategy. The combination of perfect recent harvest success, moderate-to-solid trophy potential, and 63% public land access makes S75 a strong unit within Colorado's bighorn sheep program. The main caveat is tag scarcity: with only a handful of permits issued annually, this is a unit built around patience and point accumulation, not quick draws.

How much public land is accessible in Unit S75? Public land makes up 63% of Unit S75's 449,002 acres, giving hunters a solid foundation for access without heavy reliance on private landowner permission. Hunters should still verify boundaries carefully, since more than a third of the unit remains in private ownership, and should use mapping tools to confirm exactly where public ground lies relative to planned hunting areas.
