Colorado Unit 35 Elk Hunting Guide

Colorado Unit 35 sits in the Gore Range country of the state's high-country elk range, spanning elevations from 6,137 feet up to 11,304 feet across 171,605 acres. With 76% public land, this unit gives hunters substantial room to roam without leaning on private ranch access, and it draws consistent interest from both resident and nonresident elk hunters looking at Colorado's western slope. For anyone researching Colorado Unit 35 elk hunting, the unit offers a mix of accessible terrain and rugged high country, backed by several years of harvest data worth understanding before hunters commit an application.

This is a unit that shows up regularly in online hunting forums as a busy, well-known destination — chatter about crowded camps and competition for open ground is common in discussions about this general area. That popularity cuts both ways: it means infrastructure and hunter traffic are established, but it also means solitude is not what this unit is selling. Understanding the real numbers behind harvest success, herd composition, and application logistics matters more here than in units that rely purely on word-of-mouth reputation.

HuntPilot Analysis

Is Colorado Unit 35 worth applying for? The honest answer depends on what a hunter is after. Harvest success in Unit 35 has run modest over the past three seasons — 17% in 2025, 17% in 2024, and 13% in 2023, based on unit-wide totals tracked by HuntPilot. Those numbers reflect a unit that produces opportunity but isn't a high-percentage layup. Roughly one in five to one in eight hunters connected in recent years, which is typical for a heavily-hunted, accessible western-slope unit rather than a limited-access sleeper.

The bull:cow ratio data is a more important flag for hunters trying to gauge herd quality. Across six survey years from 2018 to 2024, the average ratio has run 25:100, which is on the low end for elk herds generally. A ratio in this range typically points to heavier bull harvest pressure relative to the cow population and suggests hunters should not expect a bull-heavy woods. This isn't a herd-health red flag necessarily — many accessible, high-pressure Colorado units run lean bull ratios — but it does inform expectations. Hunters chasing raw numbers and general elk hunting experience will find Unit 35 workable. Hunters specifically chasing mature bulls in high densities should treat the ratio data as a caution sign and set expectations accordingly.

Trophy history for the counties overlapping Unit 35 is limited. There isn't a deep or consistent record of trophy-class bulls coming out of this area, and hunters should not go into this unit expecting a realistic shot at an exceptional or elite-class animal. This doesn't mean mature bulls aren't taken here — they are, every season — but the data doesn't support characterizing this as a trophy unit. Unit 35 is better framed as an opportunity unit: solid public land access, a real chance at a bull with reasonable effort, and a well-established hunting community, but not a unit hunters should bank on for a record-book animal.

The 76% public land figure is a genuine asset. With three-quarters of the unit open to public access, DIY hunters have real room to work without needing to lease or negotiate private ground, and the elevation range — from valley floor around 6,137 feet up to alpine terrain near 11,304 feet — gives hunters options to hunt lower sagebrush and timber transition zones early or push into higher basins as conditions dictate. There's no wilderness acreage in this unit, which means no Wyoming-style guide mandates apply here (this is a Colorado unit regardless), and hunters can move through the terrain without the access restrictions that come with formally designated wilderness.

Bottom line: Unit 35 is worth applying for if a hunter wants a numbers-friendly public-land elk hunt with established access and is comfortable with moderate success rates and average-to-below-average bull ratios. It is not the unit to chase if trophy potential is the primary goal.

Harvest Success Rates

HuntPilot's harvest data for Unit 35 covers three recent seasons and shows a unit with real but not exceptional hunter success:

• 2025: 1,132 hunters afield, 193 elk harvested, 17% success
• 2024: 2,016 hunters afield, 336 elk harvested, 17% success
• 2023: 1,986 hunters afield, 265 elk harvested, 13% success

These are unit-wide totals across all hunt types rather than broken out by specific hunt code, so they represent the overall pressure and outcome picture rather than any single draw's individual performance. Notably, hunter numbers dropped significantly from 2024 (2,016) to 2025 (1,132) while success rate held steady at 17%, which suggests that overall unit pressure eased somewhat in 2025 without a corresponding drop in harvest efficiency. The consistency of the 17% mark across two consecutive years, following a lower 13% in 2023, indicates a unit that trends toward high-teens success in an average year — solid for an accessible public-land unit, but nowhere near the success rates hunters see in truly limited, low-pressure draws.

Herd Health & Population Trends

The wildlife survey data available for Unit 35 spans six survey years between 2018 and 2024, with an average bull:cow ratio of 25:100. This is a lean ratio by elk-herd standards and reflects a unit where bulls make up a smaller share of the population relative to cows — common in units with sustained hunting pressure and liberal bull harvest opportunity over time. Hunters should read this ratio as an indicator of herd composition and bull availability, not as a measure of overall herd health or elk density. A unit can carry a large, stable elk population and still show a modest bull ratio if bull harvest has been consistent year over year. For hunters, the practical takeaway is to set realistic expectations around encountering mature bulls in numbers, rather than assuming a low ratio signals a herd in decline.

Trophy Quality

Trophy-record data for the counties overlapping Unit 35 shows a limited history of entries. This puts Unit 35 in the category of units where trophy-class bulls are not a realistic primary expectation. Hunters should approach this unit with opportunity-focused goals — a representative, mature bull is achievable with time and effort, but the data does not support treating Unit 35 as a trophy destination. As with all Colorado units, trophy records are logged at the county level and shared across neighboring units, so this assessment reflects the broader area rather than being unit-exclusive, but the underlying signal remains the same: this is not a unit with a strong track record of producing elite-class bulls.

Access & Terrain

Unit 35 offers 76% public land across 171,605 acres, giving DIY hunters a strong base of accessible ground relative to many Colorado elk units. The elevation range is significant — from 6,137 feet at the lowest points up to 11,304 feet in the high country — meaning hunters can expect everything from lower sagebrush and riparian transition zones to true alpine basins near timberline. This kind of vertical relief typically pushes elk through seasonal elevation shifts as weather and forage conditions change, and hunters willing to work the higher elevations away from easier access points will generally find lower hunter density.

There is no wilderness acreage listed for this unit (0%), meaning hunters won't encounter the access restrictions or guide requirements that come with formally designated wilderness areas elsewhere in the West. That absence of wilderness designation, combined with the high public land percentage, makes Unit 35 relatively straightforward to navigate for hunters willing to do their own scouting — though the tradeoff is that easier access also means more hunter traffic, consistent with the crowded, well-traveled reputation this general area carries among hunters who frequent it. Sagebrush flats at lower elevations have produced game sightings for hunters working this type of terrain in the broader region, while the high timber and basin country above tends to hold animals that have moved off more heavily pressured lower ground.

How to Apply

Colorado's elk application system requires hunters to submit during a defined window each year, and the structured data available covers both the 2026 and 2028 application cycles.

For the 2028 application cycle, applications open March 1, 2028, with a deadline of April 1, 2028, for all regular elk applications.

For the 2026 cycle, Colorado breaks out fees by residency:

Nonresident elk (2026):

• Application fee: $11
• Tag fee: $845
• License fee: $117.62 (required to apply)
• Point fee: $100
• Applications open March 1, 2026, with a deadline of April 7, 2026

Resident elk (2026):

• Application fee: $9
• Tag fee: $70
• License fee: $53.19 (required to apply)
• Point fee: $50
• Applications open March 1, 2026, with a deadline of April 7, 2026

Note that Colorado requires hunters to hold a qualifying license before they can apply for the draw — the license fee listed above is separate from and in addition to the application fee and tag fee, and it's a mandatory cost of entry into the draw process. Nonresidents should budget for all four line items (application fee, tag fee, license fee, and point fee if applicable) when calculating the true cost of applying.

Colorado's system is a true preference point structure, meaning points are more predictive of draw outcomes than in hybrid or squared-bonus states. For current draw odds and point requirements specific to Unit 35, hunters should check HuntPilot's Colorado state page at /states/co, which tracks year-specific numbers that aren't included in this overview.

Dates and fees are subject to change. Always verify current application details at the state wildlife agency website before applying.

Frequently Asked Questions

What is the terrain like in Colorado Unit 35? Unit 35 spans a wide elevation range from 6,137 feet to 11,304 feet, offering everything from lower sagebrush flats and transition timber to high alpine basins near timberline. With 76% public land across the unit's 171,605 acres, hunters have significant room to explore different elevation bands depending on season timing and weather, though there is no designated wilderness acreage in this unit.

What is harvest success in Unit 35? Recent harvest success has run 17% in both 2025 and 2024, and 13% in 2023, based on unit-wide totals. These figures reflect a unit with moderate, consistent hunter success rather than an exceptionally easy or exceptionally difficult draw to fill.

How big are the elk in Unit 35? Trophy-record data for the counties overlapping Unit 35 shows a limited history of trophy entries, meaning hunters should not expect this to be a unit that regularly produces elite or exceptional-class bulls. Most hunters here should set expectations around a representative, mature bull rather than a record-book animal.

Is Unit 35 worth applying for? For hunters prioritizing accessible public land, a well-established hunting area, and moderate but real harvest success (13-17% in recent years), Unit 35 is a reasonable option. For hunters specifically chasing trophy-class bulls or very high bull densities, the limited trophy history and lean bull:cow ratio (averaging 25:100 across recent surveys) suggest looking elsewhere or adjusting expectations.

What is the bull-to-cow ratio in Unit 35 and what does it mean? The average bull:cow ratio across six survey years (2018-2024) is 25:100, which is on the lean side for elk herds. This suggests hunters should expect fewer bulls relative to cows in the population, which can mean more competition for the bulls that are present, particularly given the unit's popularity and hunter traffic.
