Colorado Unit S06 Bighorn Sheep Hunting Guide

Colorado Unit S06 is one of the state's limited-quota bighorn sheep units, a high-country draw proposition covering 145,072 acres with elevations ranging from 5,908 to 14,107 feet. For sheep hunters building a long-term application strategy, S06 deserves a close look — not because it's an easy draw, but because the unit consistently produces high harvest success for the handful of hunters who manage to pull a tag. This article breaks down what the data actually shows for Unit S06, so hunters can decide whether to commit points and planning toward this specific unit.

Unit S06 carries no general season — every hunt here runs through Colorado's limited-quota draw system, and that includes tags covering antlered rams. There is no walk-in opportunity and no over-the-counter fallback. Public land accounts for 62% of the unit, giving DIY hunters a meaningful base of accessible terrain, though the absence of designated wilderness (0%) means hunters won't face the access restrictions that come with wilderness-area regulations in other units.

HuntPilot Analysis: Is Unit S06 Worth Applying For?

The honest answer: yes, if a hunter is already committed to the long game of sheep hunting in Colorado, but this is not a unit to expect quick results from.

Start with harvest performance, because it's the strongest data point in S06's favor. Across the available years, success rates have been outstanding. In 2025, all 5 hunters who held tags harvested a ram — a 100% success rate. The same held true in 2024 (9 of 9), 2023 (9 of 9), and 2022 (7 of 7). Only in 2021 and 2019 did success dip to 78% (7 of 9 hunters harvesting in each of those years). Averaged across the seven years of data provided, Unit S06 shows sustained, elite-level success rates that are rare even among sheep units. This tells hunters that once a tag is in hand, the terrain and sheep density in S06 give a very high probability of filling it — a sheep hunter who draws here is overwhelmingly likely to come home with a ram.

That said, the number of hunters afield each year is tiny — never more than 9 in any season covered by the data. This is a unit defined by extremely low tag volume, not by abundant opportunity. The tag quota data reinforces this: looking at the hunt-type breakdown, one hunt type saw its allocation fall from 8 tags in 2025 down to just 2 in 2026, a 75% cut. Other hunt types in the unit have held steady at very low, single-digit levels (1 to 2 tags) across 2024 through 2026. This is a unit where tags are scarce by design, and any year-over-year quota swings can swing dramatically given how small the baseline numbers are.

Trophy-wise, the counties overlapping Unit S06 carry a moderate history of producing record-book-caliber rams. That puts S06 in a middle tier — not among the handful of units known for consistently chasing elite scores, but with a credible track record of mature rams coming out of the area. Combined with the high harvest success rate, a hunter who draws S06 has real odds of connecting with a quality ram, even if record-book-caliber trophies aren't a given.

Given all of this, S06 is best suited to hunters who are already deep into Colorado's sheep points system and are specifically targeting a unit with strong on-the-ground success once drawn. It is not a unit for someone hoping for a quick draw or high-volume opportunity — this is a long-term, patience-required proposition, as sheep hunting in Colorado generally is.

Harvest Success Rates

Unit S06's harvest numbers are its standout feature. Over the seven years of data available:

• 2025: 5 hunters, 5 harvested — 100% success
• 2024: 9 hunters, 9 harvested — 100% success
• 2023: 9 hunters, 9 harvested — 100% success
• 2022: 7 hunters, 7 harvested — 100% success
• 2021: 9 hunters, 7 harvested — 78% success
• 2019: 9 hunters, 7 harvested — 78% success
• 2020: 2 hunters (harvest outcome not specified in available data)

Four of the last five reported years show perfect success. This is a strong signal that hunters who draw tags here are well-positioned, terrain and sheep visibility considered, to close the deal. Few sheep units anywhere sustain this level of consistency, and it's a major point in S06's favor for anyone deciding where to direct limited sheep points.

Trophy Quality

Trophy data for the counties overlapping Unit S06 points to moderate trophy potential. This isn't a unit with a thin or absent trophy record — rams of record-book quality have come from this area — but it also isn't among the small group of Colorado sheep units known for producing an outsized share of elite-scoring rams. Hunters should treat S06 as a unit where a mature, respectable ram is a realistic goal, understanding that trophy-caliber records are shared across the broader county area and not attributable to S06 alone. As always with bighorn sheep, every legal ram taken in a unit like this represents a significant accomplishment given how few tags exist.

Access & Terrain

Unit S06 spans a dramatic elevation gradient, from 5,908 feet up to 14,107 feet — alpine basins and rugged high country are very much in play here. At 62% public land, the majority of the unit is accessible without needing permission from private landowners, which is a meaningful advantage for hunters planning a DIY approach. With 0% designated wilderness, hunters won't need to work around wilderness-specific travel restrictions, though the terrain itself — given the elevation range — will still demand serious physical conditioning and careful route planning regardless of wilderness designation.

Forum accounts from hunters who've drawn Colorado sheep tags in high-elevation units describe this type of country as rugged, remote, and physically demanding, with terrain that rewards hunters who put in scouting time before the season. Given the elevation extremes in S06, hunters should expect everything from lower-elevation approach routes to true alpine basins near the unit's high points. HuntPilot's mapping tools, including public land overlays, can help hunters identify specific access points and glass likely sheep habitat across this elevation range before committing to a hunt plan.

How to Apply

Colorado bighorn sheep tags are allocated entirely through the state's limited-quota draw system — there is no general season and no over-the-counter option for Unit S06. Every hunt type in this unit, including those covering antlered rams, requires a successful draw application.

Colorado uses a preference point system for bighorn sheep, meaning hunters accumulate points in years they don't draw, improving their position in future draws. Residents and nonresidents apply through separate pools, and nonresidents should expect this to be a multi-year, often decades-long points commitment given how limited the tag numbers are in a unit like S06. The quota data available for S06 shows allocations in the low single digits across its hunt types, underscoring just how competitive and limited this draw is regardless of residency.

Because application structures, point requirements, and deadlines shift from year to year, hunters should not rely on static figures. For current application windows, fees, and point requirements, visit HuntPilot's Colorado state page at /states/CO, and check the Unit S06 page directly on HuntPilot for the most current draw data.

Frequently Asked Questions

Is Unit S06 worth applying for as a bighorn sheep hunter? Based on the available data, yes — if a hunter is prepared for a long-term points commitment. The unit's harvest success rate is exceptional, with 100% success in four of the last five reported years, meaning hunters who do draw a tag have a very strong chance of harvesting a ram. The tradeoff is extremely limited tag availability, so this is a unit for patient, committed applicants rather than hunters looking for a fast turnaround.

What is harvest success like in Colorado Unit S06? Harvest success in S06 has been outstanding. Recent years show 100% success in 2025 (5 of 5), 2024 (9 of 9), 2023 (9 of 9), and 2022 (7 of 7), with slightly lower but still strong 78% success in both 2021 and 2019. This makes S06 one of the more reliable units in terms of converting a tag into a harvested ram, according to HuntPilot's data.

How big are the bighorn sheep in Unit S06? Trophy records tied to the counties overlapping Unit S06 show moderate trophy potential — the area has produced quality rams, though it isn't known as a unit that consistently churns out elite record-book scores. Hunters can reasonably expect a mature ram to be attainable, with exceptional-scoring rams being possible but less common.

What is the terrain like in Unit S06? The unit covers a huge elevation range, from 5,908 feet up to 14,107 feet, encompassing everything from lower foothill terrain to true alpine basins. Public land makes up 62% of the unit, giving DIY hunters solid access, and there's no designated wilderness acreage in the unit, which simplifies travel planning compared to wilderness-heavy units elsewhere in the state.

How many tags are available in Unit S06? Tag numbers in S06 are very limited across all hunt types, with recent quotas running in the low single digits per hunt type and some types seeing significant year-over-year cuts. Because quotas shift from year to year, hunters should check HuntPilot's Unit S06 page or Colorado's published draw reports for the current allocation before applying.
