Colorado Unit 63 Mule Deer Hunting Guide
Colorado Unit 63 sits in the western slope country of Colorado, spanning a significant elevation range from roughly 5,000 feet in the lower drainages up to nearly 12,000 feet along the higher terrain. At 236,200 total acres with 59% public land, the unit offers hunters a workable mix of accessible public ground and private holdings. For hunters seriously researching mule deer draws in Colorado, Unit 63 has posted harvest numbers that consistently outperform many competing units — and the counties overlapping it carry a legitimate trophy history worth understanding before you decide where to spend your points.
The unit's 236,200 acres break into a range of terrain types driven by that nearly 7,000-foot elevation spread. Lower-elevation sagebrush flats and oak brush transition zones hold deer through early periods, while the timbered mid-elevation benches and higher alpine edges provide critical summer and transitional range. With no designated wilderness within the unit boundaries, access is comparatively straightforward — hunters aren't facing mandatory guide requirements or deep pack-in logistics just to reach huntable country. That combination of public land percentage, terrain diversity, and manageable access puts Unit 63 on the radar for both resident and nonresident mule deer applicants.
What makes this unit particularly interesting from a data standpoint is the multi-year harvest record. Over the past four seasons, Unit 63 has consistently returned success rates that most western mule deer hunters would consider excellent, and the county-level trophy history adds a layer of credibility to the unit's long-term potential. This article breaks down everything hunters need to know, including honest analysis of whether the unit is worth committing points to in 2026.
Harvest Success Rates
Unit 63's harvest data, compiled by HuntPilot, paints a clear picture of a productive mule deer unit — though with some fluctuation worth examining.
In 2022, the unit saw 702 hunters take to the field with an exceptional 83% success rate, producing 580 harvested deer. That's one of the stronger single-year performances in the recent record for this type of unit. 2023 maintained strong momentum with 793 hunters and a 72% success rate, yielding 571 harvested animals — nearly identical harvest numbers despite the slight drop in rate. 2024 brought 786 hunters afield at a 65% success rate with 514 deer harvested. And in 2025, total hunter participation dropped to 436, with 302 deer harvested at a 69% success rate.
A few things stand out in this data. First, the four-year average success rate sits comfortably above 70%, which is genuinely strong for a Colorado limited-entry mule deer unit. Second, the 2025 drop in hunter participation is notable — 436 hunters versus the 780–793 range seen in 2023 and 2024. That likely reflects a tag allocation reduction rather than a collapse in unit quality, though hunters should monitor whether participation trends continue downward. Third, even with the reduced hunter count in 2025, the 69% success rate remained solid.
For context, Colorado statewide deer success rates across limited-entry units typically run in the 50–65% range. Unit 63's consistent performance above that benchmark is a meaningful data point.
Trophy Quality
The counties overlapping Colorado Unit 63 carry an extensive trophy history in the record books. That's a meaningful designation — it places the region among the stronger mule deer producing areas of western Colorado based on historical production.
A critical caveat here: trophy records are logged at the county level, not the unit level. That means the trophy history associated with the counties overlapping Unit 63 is shared with every neighboring unit that falls within those same county boundaries. The same records can't be attributed exclusively to Unit 63 — animals may have been taken anywhere within the overlapping counties. With that said, the underlying county-level data does suggest the genetic and habitat foundation exists in this part of Colorado for bucks to reach trophy-class dimensions.
Practically speaking, hunters should calibrate expectations realistically. Even in areas with a strong trophy history, truly exceptional bucks represent a small fraction of the annual harvest. The harvest data above reflects hundreds of deer taken across all age and antler classes. Hunters focused exclusively on mature, trophy-class bucks should plan for a patient, selective hunt and understand that the unit's high success rates likely include a significant percentage of younger class bucks taken by hunters not holding out for a specific age class.
For hunters willing to be selective and pass on younger bucks, the county-level trophy history suggests the potential exists — but it's never guaranteed in any unit, in any state, in any given year.
Herd Health & Population Trends
Wildlife survey data for Unit 63 is limited — HuntPilot's structured data reflects a single survey year (2024), which recorded an average buck-to-doe ratio of 35:100.
A 35:100 buck-to-doe ratio is a reasonable but not exceptional benchmark for Colorado mule deer. Colorado Parks and Wildlife generally targets ratios in the 25–35:100 range as an indicator of a functionally healthy deer herd, so this reading falls at the high end of that acceptable range. It suggests the buck component of the herd is intact, though it doesn't indicate an unusually buck-heavy population.
One important limitation: with only a single survey year in the data, trend analysis isn't possible from this dataset alone. A single snapshot tells hunters the current state but doesn't indicate whether the ratio is improving, declining, or stable over time. Hunters doing deeper research should cross-reference CPW's official herd management reports, which often contain multi-year survey data, population objectives, and post-season assessments for individual units. The single-year reading here is a useful data point, not a complete population picture.
The harvest numbers are arguably a more reliable indicator of unit health and productivity over time. Four consecutive years of 65–83% success rates, with hundreds of deer harvested annually, reflects a herd that has been sustaining consistent hunting pressure without obvious collapse — that's a meaningful indirect indicator.
Access & Terrain
At 59% public land across 236,200 total acres, Unit 63 offers hunters approximately 139,000 acres of publicly accessible ground. That's a meaningful amount — enough that DIY hunters can plan a legitimate hunt without depending on private land access. However, the remaining 41% of the unit is private, and in Colorado's western slope country, private land often controls key lower-elevation transition zones, creek bottoms, and winter range. DIY hunters will need to do their homework on specific public/private boundaries before committing to a hunting location.
The elevation range — 5,002 to 11,788 feet — is one of the unit's defining characteristics. That nearly 7,000-foot spread creates a genuinely diverse landscape. The lower sagebrush and oak brush country at the 5,000–7,000 foot band is classic mule deer habitat, providing early-season feed and cover. Mid-elevation terrain typically carries mixed conifer and aspen, which holds deer during transitional periods. Higher-elevation terrain approaching 11,000–12,000 feet represents the summer range and early-season holding areas where bucks spend time before being pushed down by weather.
With zero designated wilderness in the unit, hunters don't face the access complications that come with wilderness-heavy units. There are no mandatory guide requirements for nonresidents based on wilderness designation here. Colorado does not have a Wyoming-style guide requirement for wilderness access — nonresidents can hunt entirely DIY throughout Colorado, including Unit 63. The lack of wilderness also means the unit's road and access network is generally more developed than backcountry wilderness units, which makes it more practical for hunters without horses or large pack-out logistics.
The terrain is still demanding by any standard. A nearly 12,000-foot high point means hunters pursuing bucks in the upper elevations will be working in legitimate high-country conditions. Physical fitness and preparation for sudden weather changes are non-negotiable at those elevations.
HuntPilot Analysis
Is Unit 63 worth applying for? Based on the available data, the answer is a qualified yes — with some important nuances.
The harvest data is the unit's strongest selling point. A four-year average success rate consistently above 65%, peaking at 83% in 2022, places Unit 63 among the more productive limited-entry mule deer units in Colorado by raw success metrics. Hunters who draw this tag have a genuinely high probability of going home with a deer. That matters — many Colorado mule deer draw hunts return success rates significantly lower.
The trophy history at the county level adds credibility, though hunters should be careful not to over-weight county-level records when making a unit-specific decision. The data supports trophy potential in the broader region, but Unit 63's specific contribution to those records versus neighboring units in the same counties is unknown.
The 2025 participation drop (436 hunters versus ~785 the year prior) is worth watching. If it reflects a tag reduction, the lower hunter pressure could actually improve trophy buck encounters and success rates per hunter. If it reflects something else — unit consolidation, boundary changes, or declining applicant interest — hunters should dig deeper before committing points.
At 59% public land with no wilderness complications, the unit is DIY-viable for nonresident hunters, which adds practical value compared to guide-required wilderness units elsewhere in the state.
The primary risk: this is a competitive limited-entry unit in Colorado, meaning it requires a multi-year point investment for most nonresidents. Residents applying with points should check current draw competitiveness on the HuntPilot unit page at huntpilot.ai/states/co before making a point-burn decision.
Bottom line: Unit 63 looks like a legitimate, data-supported target for hunters who have accumulated points and are looking for a high-success Colorado mule deer hunt with trophy potential in the county system. It is not a "burn your first points here" unit — it rewards patient point accumulation.

Frequently Asked Questions
What is the terrain like in Colorado Unit 63? Unit 63 spans a dramatic elevation range from approximately 5,000 feet to nearly 12,000 feet, covering sagebrush and oak brush at the lower elevations, mixed conifer and aspen at mid-elevation, and high-country terrain approaching the upper limits. The unit has no designated wilderness, making access comparatively straightforward. With 59% public land across 236,200 acres, DIY hunters have substantial ground to work, though private land controls portions of the lower elevations and hunters need to verify specific boundaries before hunting.
What is the harvest success rate in Colorado Unit 63 mule deer hunting? Unit 63 has posted strong success rates over the past four seasons: 83% in 2022 (702 hunters, 580 harvested), 72% in 2023 (793 hunters, 571 harvested), 65% in 2024 (786 hunters, 514 harvested), and 69% in 2025 (436 hunters, 302 harvested). The four-year average is well above 70%, which is significantly stronger than typical Colorado limited-entry mule deer unit averages.
How big are the mule deer in Colorado Unit 63? The counties overlapping Unit 63 carry an extensive trophy history in the record books, indicating the region has a strong history of producing trophy-class mule deer. That said, trophy records are county-level data shared across multiple units — individual unit attribution isn't possible. Hunters should expect a range of buck quality across the annual harvest, with truly exceptional bucks representing a small fraction of total deer taken. Selective, patient hunters have genuine opportunity given the county-level trophy pedigree of this part of Colorado.
Is Colorado Unit 63 worth applying for? Based on the available harvest data and trophy history, Unit 63 is a strong candidate for hunters with accumulated preference points who want a high-probability mule deer hunt with legitimate upside on buck quality. The four-year harvest success average, terrain diversity, 59% public land, and no wilderness complications make it a practical choice for both resident and nonresident applicants. It is a competitive limited-entry draw, however — hunters should check current draw competitiveness before committing points at huntpilot.ai/states/co.
What does it cost to apply for Colorado Unit 63 mule deer as a nonresident? For 2026, nonresidents need to budget a $117.62 license (required to apply), an $11.49 application fee, and a $507.00 tag fee if drawn — totaling approximately $636 in mandatory costs. If not drawn, a $100 point fee keeps point accumulation active. Applications open March 1, 2026 and close April 7, 2026, with results posted May 26, 2026.
