Colorado Unit S33 Bighorn Sheep Hunting Guide
Colorado Unit S33 sits in high alpine terrain ranging from 8,293 to 14,266 feet in elevation — the kind of country that defines bighorn sheep habitat in the American West. Spanning 286,017 total acres with an exceptional 93% public land base, S33 offers hunters rare combination of accessibility and genuine wilderness character. With only 9% designated wilderness, the vast majority of this public ground can be reached without mandatory guide requirements, making it one of the more practical self-guided options for nonresidents pursuing one of North America's most coveted big game tags.
Bighorn sheep tags in Colorado are among the rarest in the Western United States. Unit S33 consistently fields a small, tightly controlled group of hunters each year — a structure that directly reflects the measured management approach Colorado Parks and Wildlife applies to its sheep herds. For hunters who have been building points toward a sheep tag, understanding the nuances of S33's harvest history, terrain, and trophy character is essential before committing to an application.
This guide draws on data compiled by HuntPilot to give hunters a clear, honest look at what Unit S33 delivers — and what it demands.
Harvest Success Rates
Unit S33 produces some of the strongest harvest success figures in Colorado's sheep draw. The data from recent years tells a consistent story:
- 2025: 22 hunters, 16 harvested — 73% success
- 2024: 23 hunters, 17 harvested — 74% success
- 2023: 21 hunters, 14 harvested — 67% success
- 2022: 22 hunters, 12 harvested — 55% success
- 2021: 15 hunters, 12 harvested — 80% success
- 2019: 12 hunters, 9 harvested — 75% success
Across the six years from 2019 to 2025 with meaningful hunter counts, success rates have averaged in the low-to-mid 70% range — an excellent benchmark for a sheep unit. The 2022 season stands as the low point at 55%, while 2021 reached 80%. The 2020 data (1 hunter, 100% success) likely reflects an anomalous draw year and carries no statistical weight.
What these numbers confirm is that hunters who draw a tag in S33 have a very strong probability of filling it. Sheep hunting remains physically demanding and logistically complex regardless of unit, but S33's track record suggests that rams are accessible to hunters willing to put in the work. The consistency of 20-plus hunters per year in recent seasons also indicates stable tag allocations and a herd that is sustaining itself under harvest pressure.
Trophy Quality
The counties overlapping Unit S33 carry a moderate history of trophy-class bighorn sheep records. This positions S33 as a unit with genuine but not exceptional trophy pedigree — hunters should expect legitimate opportunities at quality rams, with the understanding that truly record-class animals are rare events anywhere in Colorado.
It is worth noting, as it is for every sheep unit, that trophy records are logged by county rather than by individual unit. The same county-level entries are shared across all units that overlap those counties, meaning neighboring units draw from the same trophy history pool. A moderate rating for the overlapping counties is still meaningful signal — it confirms that rams of trophy caliber have been taken in this country — but hunters targeting record-book quality specifically should weigh this alongside current herd surveys and on-the-ground scouting.
For most S33 applicants, the draw itself is the prize. A mature bighorn ram — regardless of score — is a once-in-a-career animal for the vast majority of hunters.
Access & Terrain
Unit S33's elevation band of 8,293 to 14,266 feet encompasses virtually the full spectrum of alpine sheep habitat. The lower reaches provide transitional terrain where sheep move seasonally, while the upper elevations above timberline offer the classic cliff-and-crags environment that bighorns depend on year-round. Hunters should be prepared for extreme vertical gain, unstable footing, and rapidly changing weather that characterizes high-alpine hunting in Colorado.
The 93% public land base is a standout feature of this unit. Very few western sheep units combine this level of public access with the size and elevation range that S33 offers. DIY hunters — both residents and nonresidents — have genuine options here, unlike units where private land blocks critical access corridors.
The 9% wilderness designation means the majority of the unit is outside designated wilderness boundaries. Colorado does not impose guide requirements on nonresidents hunting in wilderness areas, so wilderness access within S33 is available to all hunters regardless of residency. Hunters comfortable with backcountry navigation and high-altitude camping can pursue sheep in the unit's most remote terrain without any mandatory guide requirement.
Physical conditioning is non-negotiable for S33. The vertical relief alone — nearly 6,000 feet from floor to summit — means hunters must be prepared to operate effectively at elevation under load. Most successful sheep hunters in alpine Colorado units pack into base camps, glass extensively from vantage points, and commit to multi-day pursuits once a target ram is located.
Herd Health & Population Trends
The harvest data itself offers a useful proxy for herd health in the absence of full population survey data. Unit S33 has sustained 15–23 hunters annually across the 2019–2025 period with success rates that have held largely stable or improved. A unit experiencing significant herd decline would typically see tag reductions and tighter allocations — the consistency in S33's hunter numbers suggests Colorado Parks and Wildlife is managing the herd on a trajectory they consider sustainable.
Bighorn sheep populations across the West face ongoing challenges from respiratory disease, particularly in herds that come into contact with domestic sheep and goats. Hunters researching S33 should consult the most current CPW herd management reports for unit-specific population estimates, bull-to-ewe ratios, and any disease history — information that is updated annually and critical to understanding long-term trajectory.
HuntPilot Analysis: Is Unit S33 Worth Applying For?
The direct answer: yes — with clear eyes about what you're applying for.
Unit S33's harvest data is among the most encouraging in Colorado's sheep draw. A sustained success rate averaging in the low-to-mid 70s over seven years is not luck — it reflects a combination of adequate ram populations, manageable terrain, and a public land base that gives hunters real options. For a species where success rates below 50% are common in difficult units, S33's numbers stand out.
The 93% public land is a genuine differentiator. Hunters will not be stacking up against private land barriers or paying trespass fees to access core habitat. Combined with only 9% wilderness, the unit is about as DIY-friendly as a Colorado sheep unit gets.
The trophy picture is moderate. Hunters targeting record-book rams should temper expectations and understand that the counties overlapping S33 have produced trophy rams historically, but not at the elite frequency of the state's top-tier sheep units. That said, a Colorado sheep tag in any unit is a legitimate bucket-list hunt, and a mature S33 ram is a tremendous trophy by any honest standard.
The real calculus for most hunters is points. Colorado bighorn sheep draw is highly competitive. Residents and nonresidents alike typically invest many years of preference points before drawing a sheep tag anywhere in the state. Hunters should evaluate S33 in the context of their current point totals and the draw odds for the specific hunts they're eligible for — visit HuntPilot's Colorado page at huntpilot.ai/states/co for current draw odds by hunt and point level before finalizing your application strategy.
Bottom line: S33 is a legitimate, well-managed sheep unit with strong harvest success, excellent public access, and moderate trophy potential. For hunters who draw, the odds of filling their tag are genuinely good. For hunters still building points, it warrants serious consideration in a state where sheep tags are always scarce.

Frequently Asked Questions
What is the terrain like in Colorado Unit S33?
Unit S33 spans a dramatic elevation range from 8,293 to 14,266 feet, covering transitional foothills, alpine meadows, timbered slopes, and rugged cliff faces above timberline. The upper elevations above 11,000–12,000 feet represent classic bighorn sheep habitat — open rocky terrain with the commanding views and escape cover that rams favor. Hunters should expect extended glassing sessions from high vantage points, significant elevation gain during stalks, and the unpredictable weather conditions typical of Colorado's high country. This is serious backcountry terrain that demands physical preparation.
What is the harvest success rate in Colorado Unit S33?
Unit S33 has produced strong and consistent harvest results. From 2019 through 2025, annual success rates have ranged from 55% (2022) to 80% (2021), with most years falling in the 67–75% range. The 2024 season saw 23 hunters and a 74% success rate; 2025 posted 73% success across 22 hunters. For a Colorado sheep unit, these figures are well above average and indicate both stable ram populations and huntable terrain.
How big are the bighorn sheep in Colorado Unit S33?
The counties overlapping Unit S33 have a moderate history of trophy-class rams. Hunters can realistically expect encounters with mature rams, though truly exceptional record-book animals are rare — as they are across virtually all sheep habitat in North America. Most hunters who draw a sheep tag in S33 should hunt for the best mature ram they can locate rather than holding out for record-book measurements. Any mature Colorado bighorn ram is a trophy of a lifetime regardless of final score.
Is Colorado Unit S33 worth applying for?
For hunters with meaningful preference point totals who are evaluating their sheep application, S33 presents a compelling case. The unit's 93% public land base, manageable wilderness percentage, and sustained 70%+ success rates in most recent years make it one of the more practical and productive sheep units in Colorado's draw. Trophy potential is moderate rather than elite, but the combination of huntable terrain and accessible public land is genuinely difficult to find in a Colorado sheep tag. For current draw odds that will determine whether S33 is realistically within reach of your point total, check HuntPilot's Colorado unit page before the April 7, 2026 application deadline.
Can nonresidents hunt Colorado Unit S33 without a guide?
Yes. Colorado does not require nonresident hunters to hire a licensed guide, even in designated wilderness areas. With 93% public land and only 9% wilderness, the vast majority of Unit S33 is accessible to self-guided hunters regardless of residency. Nonresidents are free to plan and execute a DIY sheep hunt in S33, though the difficulty of high-alpine bighorn hunting makes thorough pre-season scouting — whether in person or through satellite imagery and mapping tools — essentially mandatory for a realistic chance at success.
