Colorado Unit 42 Elk Hunting Guide
Colorado Unit 42 sits in a broad swath of Colorado terrain spanning elevations from 4,771 to 11,098 feet — a range that creates diverse habitat from lower sagebrush and oakbrush benches up through dense timber and alpine transition zones. The unit covers 387,358 total acres with 57% in public ownership, giving DIY hunters meaningful access without requiring private land connections. For hunters researching where to invest Colorado preference points or simply looking for a high-volume elk unit worth serious consideration, Unit 42 delivers a consistent track record backed by multi-year harvest data.
Elk hunting in Colorado Unit 42 draws significant pressure across recent seasons — upward of 4,000 to 6,000 hunters depending on the year — but the unit continues to produce harvestable elk at a rate that keeps it relevant on any serious hunter's radar. The combination of accessible terrain, majority public land, and repeatable success rates makes this unit a realistic target for both residents and nonresidents willing to put in the legwork.
Harvest Success Rates
The harvest data for Colorado Unit 42 tells a consistent story: hunters here succeed at roughly 20–22% annually, a figure that has remained stable across four recent seasons tracked by HuntPilot.
| Year | Hunters | Harvested | Success Rate | |------|---------|-----------|--------------| | 2025 | 4,652 | 909 | 20% | | 2024 | 6,185 | 1,318 | 21% | | 2023 | 6,358 | 1,302 | 20% | | 2022 | 3,237 | 700 | 22% |
That stability is meaningful. A unit that bounces between 12% and 28% year to year signals herd volatility or management swings. Unit 42 has shown none of that — the floor holds near 20% and the ceiling doesn't drift far above. For hunters who value predictability when budgeting time and travel, that consistency is a genuine selling point.
Hunter participation saw a notable spike in 2023–2024 (over 6,000 hunters each year) compared to 2022 and 2025 levels in the mid-3,000 to mid-4,000 range. Despite the pressure surge in 2023–2024, success rates held steady, suggesting the elk population and habitat in Unit 42 can absorb significant hunting effort without dramatic impact on per-hunter outcomes.
Trophy Quality
Counties overlapping Colorado Unit 42 carry a moderate history of trophy-class elk production. This is not a unit synonymous with the elite, once-in-a-lifetime bulls that define Colorado's most celebrated limited-entry draws, but it is not a blank slate either. Trophy-class animals have been taken from this area over time, and the county-level record history reflects a unit that occasionally produces animals worth measuring.
Hunters entering Unit 42 with realistic expectations — prioritizing meat in the freezer and a quality hunting experience over a benchmark bull — are well-positioned. Hunters specifically targeting a record-book-caliber animal would be better served applying preference points toward more specialized, lower-pressure limited-entry units elsewhere in Colorado. That said, any unit with an elevation band reaching above 10,000 feet and 57% public land can hold surprises for hunters willing to go deep and hunt hard.
Herd Health & Population Trends
Wildlife survey data covering six survey years between 2018 and 2024 shows an average bull-to-cow ratio of 28 bulls per 100 cows in Colorado Unit 42. This figure reflects a herd under moderate hunting pressure — ratios in that range are typical of units that see substantial combined permit allocation across bull and antlerless tags. It does not indicate a herd in decline, but it does signal that mature bulls face consistent harvest pressure and that hunters targeting older age-class animals will need to work for them.
A 28:100 bull-to-cow ratio across six survey years is a more reliable data point than any single-year snapshot. The multi-year average smooths out the noise from small survey samples or unusual weather years and gives a realistic picture of what the bull component of this herd looks like. Hunters should go in expecting a mix of younger bulls, raghorns, and occasional mature bulls — not a unit dominated by heavy-antlered elk at every glance.
For cow elk hunters, the herd structure data suggests a healthy, productive cow segment. Units with bull-to-cow ratios in this range typically maintain good calf recruitment, which supports sustainable harvest of antlerless tags over time.
Access & Terrain
Unit 42 covers 387,358 acres with 57% in public ownership — a majority-public unit that gives DIY hunters legitimate access options across a large footprint. No wilderness area exists within the unit, which eliminates the outfitter requirement that applies to nonresidents hunting Wyoming wilderness and simplifies access logistics for hunters of all residencies in this Colorado unit.
The elevation range of 4,771 to 11,098 feet creates layered habitat that elk use differently through the season. Lower elevations hold oakbrush, sagebrush parks, and transition timber — country where elk feed and often hold during periods of lower hunting pressure. Upper elevations push into dense conifer and eventually alpine timber edge where bulls stage during the rut and retreat when pressured.
With no wilderness designation, the majority of this terrain is accessible by vehicle on forest roads and two-track, though hunters willing to push beyond the road network will consistently encounter less pressure and potentially better elk. The 57% public land figure means roughly 4 in 10 acres is private — hunters should load accurate land ownership maps before heading afield to avoid inadvertently crossing onto private ground.
Physically, the terrain demands a reasonable fitness baseline. Hunting the upper reaches of the unit at 10,000-plus feet means steep country, downed timber, and variable weather. Hunters planning to push into the higher elevations should be prepared for demanding pack-out conditions if successful.
HuntPilot Analysis
Is Colorado Unit 42 worth applying for?
The straightforward answer is yes — with appropriate expectations attached.
Unit 42 is a high-volume elk unit that consistently delivers a 20–22% overall success rate across thousands of hunters. That is not an elite success figure, but it is honest and repeatable. The unit does not appear to be collapsing under pressure — four seasons of data show stable harvest rates even when hunter numbers climbed past 6,000. That kind of resilience matters when evaluating a unit for the long term.
Trophy potential is moderate. Hunters targeting a wall-worthy bull should look elsewhere unless they are working with significant preference points and drawing a specialized limited-entry tag within a broader unit system. For hunters who want a realistic shot at harvesting an elk — bull or cow — in accessible public land country without the multi-decade point investment that defines Colorado's top-tier trophy units, Unit 42 presents a viable option.
The 57% public land base is a meaningful advantage. Nonresident hunters in particular benefit from knowing they can work public ground without relying on landowner permission or outfitter connections. Colorado does not require nonresidents to use guides anywhere in this unit, making it a legitimate DIY destination.
The consistent pressure — thousands of hunters annually — is the primary caveat. Elk in Unit 42 face significant disturbance across the season, and hunters who expect to punch a tag on a mature bull without covering serious ground will likely be disappointed. Success here requires effort: early starts, willingness to push beyond road corridors, and flexibility to adapt when elk move under pressure.
For residents building points, Unit 42 may draw without a heavy point investment depending on the specific permit type. For nonresidents, the draw is more competitive given the nonresident tag allocation structure Colorado uses.

How to Apply
Colorado elk applications for Unit 42 run through the state's centralized draw system. For 2028, applications for all regular elk permits open March 1, 2028 and close on April 1, 2028. Hunters should note the application window is exactly one month — missing the April 1 deadline means waiting another full year.
For 2026, detailed fee breakdowns are available:
Resident (2026):
- Application fee: $9
- Tag fee: $70
- License fee: $53.19 (required to apply — must be purchased before submitting)
- Preference point fee (if applying for points only): $50
- Application opens: March 1 | Deadline: April 7
Nonresident (2026):
- Application fee: $11
- Tag fee: $845
- License fee: $117.62 (required to apply — must be purchased before submitting)
- Preference point fee (if applying for points only): $100
- Application opens: March 1 | Deadline: April 7
The license fee is not optional — Colorado requires hunters to hold a valid license before the draw application is accepted. Nonresidents should budget the full $973.62 (application + tag + license) if they draw, plus travel, gear, and any additional costs. Preference point-only applicants pay the application fee plus the point fee without the tag or license cost.
Colorado uses a preference point system for elk draws. Highest-point holders are drawn first in most limited-entry permit pools. Hunters who do not draw accumulate a point each unsuccessful year. Building points in Unit 42 or adjacent units can improve draw odds over multiple seasons depending on permit type and demand.

Frequently Asked Questions
What is the terrain like in Colorado Unit 42?
Unit 42 spans elevations from approximately 4,771 to 11,098 feet, creating a wide range of habitat types. Lower portions of the unit hold sagebrush, oakbrush, and transitional timber — the kind of country elk use for feeding and lower-pressure loafing. Upper elevations push into dense conifer timber and alpine transition zones. The unit has no designated wilderness, so most terrain is accessible without a guide requirement. Hunters targeting elk in the upper reaches should expect steep, demanding country that rewards physical fitness and willingness to move away from roads.
What is the harvest success rate in Colorado Unit 42?
Unit 42 has produced a consistent 20–22% overall harvest success rate across the four most recent seasons with complete data. In 2025, 909 of 4,652 hunters harvested elk (20%). In 2024, 1,318 of 6,185 hunters succeeded (21%). In 2023, 1,302 of 6,358 hunters tagged out (20%). In 2022, 700 of 3,237 hunters were successful (22%). The stability of these rates across significant variation in hunter numbers is a reliable indicator of consistent elk availability in the unit.
How big are the elk in Colorado Unit 42?
Trophy potential in Unit 42 is moderate based on the county-level trophy history overlapping the unit. The unit has produced trophy-class animals over time, but it is not among Colorado's elite limited-entry trophy destinations. Hunters focused primarily on filling the freezer or harvesting their first elk will find Unit 42 well-suited to that goal. Hunters with a hard minimum on trophy size would be better served researching Colorado's most coveted limited-entry draws where the unit-specific quality ceiling is demonstrably higher.
Is Colorado Unit 42 worth applying for?
For hunters seeking a realistic, DIY-accessible elk hunt on majority public land with a reliable 20%+ success rate, Unit 42 is genuinely worth considering. The unit is not a trophy destination, but it is a productive and consistent one. The 57% public land base, zero wilderness complication, and multi-year harvest stability make it an honest option for residents and nonresidents alike. Trophy hunters building a preference point strategy toward elite limited-entry bulls may find better returns elsewhere, but meat hunters and experience-focused hunters will find Unit 42 delivers.
What do the bull-to-cow ratios tell us about elk in Unit 42?
The six-year average bull-to-cow ratio of 28:100 is consistent with a unit under moderate-to-heavy combined harvest pressure. This ratio is typical for high-volume elk units across Colorado and reflects a herd where bulls are available but face consistent pressure from significant annual hunter participation. It does not indicate an unhealthy herd — the cow component appears robust based on stable recruitment — but hunters should calibrate expectations toward a mixed-age bull population rather than a unit carrying an unusually high proportion of mature animals.
