Colorado Unit 33 Mule Deer Hunting Guide
Colorado Unit 33 sits in the northwestern corner of the state, spanning 266,312 acres across an elevation range of 5,300 to 11,456 feet. That vertical spread creates a diversity of habitat — from lower sagebrush and pinyon-juniper benches to higher timber and alpine terrain — that defines the character of mule deer hunting here. With 76% public land, the unit offers genuine DIY access across the majority of its acreage, and hunters willing to put in the scouting time will find huntable ground without needing to knock on private doors.
Mule deer hunting in Colorado Unit 33 has attracted steady interest from both residents and nonresidents over recent years, and the harvest data tells a story of a unit trending upward in success after a period of challenges. The unit is not one of Colorado's elite trophy destinations — hunters should come in with calibrated expectations — but it offers accessible public land, reasonable draw timelines, and a legitimate chance at a mature buck for those who do their homework.
This article pulls data from HuntPilot's analysis of Colorado Unit 33 to give hunters a grounded, honest picture of what to expect before they apply.
Harvest Success Rates
The most telling story in Unit 33 right now is the trajectory of harvest success rates, and that trend is worth examining carefully.
In 2022, Unit 33 saw 2,203 hunters take the field, with 623 harvested — a 28% success rate. That climbed modestly to 31% in 2023 (722 harvested from 2,304 hunters), then edged up to 35% in 2024 (859 harvested from 2,484 hunters). The most notable data point comes from 2025, where 1,135 hunters put 507 deer on the ground for a 45% success rate.
That 2025 number demands context. The hunter count dropped dramatically — from 2,484 in 2024 to 1,135 in 2025 — while the success rate jumped to 45%. This pattern often reflects a tag reduction or a significant shift in draw demand rather than a sudden explosion in deer numbers. Fewer hunters in the field, particularly if fewer tags were issued, can produce higher per-hunter success without necessarily indicating a stronger deer population. Hunters should not interpret the 2025 success spike as a signal that Unit 33 has dramatically rebounded.
Across the four-year window, the average success rate sits in the low-to-mid 30s — respectable for a Colorado unit that draws hunters at volume. Hunters who go in with a realistic mindset, put in the glassing time, and are selective about shot opportunities will find those odds workable.
Trophy Quality
The counties overlapping Colorado Unit 33 carry a qualifying history in the trophy record books. Based on the data available, the area has produced trophy-class animals, and the region's proximity to some of Colorado's historically productive mule deer country supports a moderate trophy potential assessment.
That said, forum sentiment and population management history temper expectations. Colorado Parks and Wildlife has adjusted population objectives in parts of this region in response to habitat changes — increased recreation pressure and development have impacted the quality and extent of available deer habitat. This is consistent with broader trends across western Colorado, where many units that once produced exceptional bucks regularly have seen declining age-class quality as populations have been managed downward to match reduced habitat carrying capacity.
The honest take: trophy-class bucks exist in Unit 33 and the surrounding counties, but they are not common. Hunters specifically targeting a record-book-caliber buck should understand that Unit 33 is not among Colorado's top-tier trophy destinations. It is a unit where a mature, representative buck is a realistic and rewarding goal, and where exceptional bucks do occasionally appear — but those animals are the exception rather than the rule.
Herd Health & Population Trends
Wildlife survey data for Unit 33 is limited — HuntPilot's available records reflect a single survey year, 2024, which recorded an average buck-to-doe ratio of 21:100.
That ratio is on the low end of what wildlife managers consider a healthy, huntable population. A buck-to-doe ratio in the low 20s typically indicates significant hunting pressure on bucks, a young age structure in the buck cohort, or both. It does not suggest a collapse, but it does indicate that mature bucks — the age class that produces the most rewarding hunting and the largest antlers — are not abundant relative to does. One survey year of data is insufficient to draw strong trend conclusions, but the ratio is consistent with the broader narrative from land managers who have noted habitat quality issues in the unit.
Hunters should not expect to encounter large numbers of mature bucks on any given day in the field. Covering ground, glassing efficiently from elevation, and being patient in areas that hold undisturbed does during the breeding season are the strategies most likely to connect a hunter with a representative buck.
Access & Terrain
With 76% public land and zero designated wilderness, Unit 33 is about as DIY-accessible as a Colorado mule deer unit gets. There are no wilderness area restrictions that would require nonresident hunters to engage a licensed outfitter — the entire unit is open to self-guided hunting on the public land portion.
The elevation range of 5,300 to 11,456 feet creates distinct habitat zones. Lower elevations hold sagebrush flats, pinyon-juniper country, and broken canyon terrain — classic early-movement mule deer habitat. As elevation climbs, hunters encounter open parks, aspen stands, and timber that deer use extensively through the season. The upper end of the unit's elevation range reaches into subalpine terrain that pushes well above 11,000 feet, which will see earlier season deer pushed downward by the first significant snowfall.
Understanding this vertical migration pattern is critical for timing a hunt. Deer that are holding in high parks and timber during the early portion of the season will compress into middle and lower elevations as conditions deteriorate. Hunters who can work the transition zones — glassing from ridges that allow them to cover both open parks and timbered escape cover — tend to encounter the most deer.
The absence of wilderness in this unit is a practical advantage. Road access points are available throughout much of the unit, and hunters can run a mobile camp strategy without the logistics burden of a remote pack-in operation. That said, competition for accessible country is real — this unit draws significant hunter pressure, particularly during the most popular draw windows. Hunters who push farther from roads and trailheads will generally find less pressure and better odds at undisturbed deer.
HuntPilot Analysis: Is Colorado Unit 33 Worth Applying For?
The honest assessment is mixed — and that context matters when deciding where to invest application dollars.
The case for Unit 33: The unit checks real boxes. Seventy-six percent public land with no wilderness means genuine DIY access across most of the acreage. The draw has historically been approachable — this is not a long-term point accumulation unit for most hunters, and residents in particular can expect to draw without significant wait. Harvest success rates in the 30–45% range are competitive with many accessible Colorado units. For hunters looking to fill a deer tag on public land with a fair chance at a mature buck, Unit 33 is a functional choice.
The case for caution: The 2024 buck-to-doe ratio of 21:100 is low. Forum accounts and CPW's own habitat management decisions indicate that this unit has faced challenges — recreation pressure, development, and habitat degradation have all been cited as contributing factors. Trophy expectations should be modest. The spike in 2025 success rates coinciding with a sharp drop in hunter numbers warrants watching in future seasons — if it reflects a tag reduction rather than herd improvement, the underlying population story has not necessarily changed.
Who this unit suits best: Resident hunters looking for a drawable deer tag on accessible public ground with reasonable harvest odds. Nonresidents who have applied for more competitive units and want a backup option, or who are in the early stages of building a western mule deer hunting history, will also find Unit 33 workable. It is not the right application for a nonresident burning multiple points in pursuit of a record-book buck — there are better uses of that point investment in Colorado.

Frequently Asked Questions
What is the terrain like in Colorado Unit 33?
Unit 33 covers 266,312 acres spanning elevations from 5,300 to 11,456 feet. The terrain runs from sagebrush flats and pinyon-juniper canyon country at lower elevations up through aspen and conifer timber into subalpine parks near the unit's highest elevations. It is accessible four-wheel-drive country throughout much of the unit — no wilderness designation means hunters can operate from vehicle-based camps and still access quality terrain. Expect open glassing country mixed with timbered draws and benches.
What is the harvest success rate in Colorado Unit 33?
Recent harvest data shows Unit 33 averaging in the low-to-mid 30s over the past several years. Specifically: 28% in 2022, 31% in 2023, 35% in 2024, and 45% in 2025 (on a significantly reduced hunter count). The multi-year trend from 2022 to 2024 shows gradual improvement. Hunters with solid scouting and reasonable buck criteria should be competitive with those odds.
How big are the mule deer bucks in Colorado Unit 33?
Unit 33 and the counties it overlaps have a qualifying history in the trophy record books, but realistic expectations should be moderate. The 2024 buck-to-doe ratio of 21:100 reflects a buck cohort under pressure, and the age structure likely skews young. Trophy-class bucks are present but uncommon. Most hunters will encounter younger bucks, with mature animals available to those who invest in thorough glassing and are willing to pass on smaller deer.
Is Colorado Unit 33 worth applying for?
It depends on the hunter's goals. For residents seeking an accessible, drawable deer tag on 76% public land with harvest odds in the 30–45% range, Unit 33 offers solid value. For nonresidents with accumulated preference points specifically targeting a trophy-class buck, there are stronger Colorado options worth considering. The unit's draw difficulty is approachable compared to many Colorado deer units, making it a reasonable application for hunters prioritizing opportunity over maximum trophy potential.
What does it cost to apply for a Colorado Unit 33 mule deer tag in 2026?
For residents, the all-in cost to apply is approximately $113 — combining the $53.19 license fee, $8.93 application fee, and $51.00 tag fee if drawn. Nonresidents should budget approximately $636 to apply and draw a tag — covering the $117.62 license fee, $11.49 application fee, and $507.00 tag fee. The application deadline for both resident and nonresident applicants is April 7, 2026, with applications opening March 1, 2026.
