Colorado Unit 500 Mule Deer Hunting Guide

Colorado Unit 500 sits high in some of the state's most rugged alpine country, with elevations ranging from 9,035 feet at the low end to 13,827 feet along its highest ridgelines. For hunters researching mule deer opportunity in this unit, the first thing to understand is that every hunt here is limited-quota — there is no general season option for Unit 500. That single fact shapes everything about how hunters should approach applying, scouting, and setting expectations for this high-country deer unit.

At 103,662 total acres with 72% public land, Unit 500 offers a meaningful base of accessible ground for DIY hunters, though the terrain itself — steep, high-elevation, and physically demanding — will do more to limit hunter success than land ownership will. This is not a unit where hunters casually stumble into deer; it rewards physical conditioning, careful glassing, and a willingness to hunt well above 10,000 feet.

HuntPilot Analysis: Is Unit 500 Worth Applying For?

The honest answer depends heavily on what a hunter is looking for. Unit 500 is a limited-quota unit only — there's no walk-in, buy-a-tag-over-the-counter option here, which immediately signals that Colorado Parks and Wildlife is managing this herd with some intentionality around hunter numbers and pressure.

Recent harvest data paints a picture of a unit that produces moderate, somewhat inconsistent success. Looking at the last six years of unit-wide harvest figures pulled from HuntPilot's database:

• 2025: 173 hunters, 37 harvested, 21% success
• 2024: 216 hunters, 40 harvested, 19% success
• 2023: 220 hunters, 48 harvested, 22% success
• 2022: 180 hunters, 14 harvested, 8% success
• 2021: 294 hunters, 38 harvested, 13% success
• 2020: 124 hunters, 31 harvested, 25% success

Success rates have bounced between 8% and 25% over this six-year window, which is a wide swing for a limited-quota unit. The 2022 season stands out as an outlier low point at just 8% success, while 2020 and 2023 both cracked into the low-20s percentage range. There's no clean upward or downward trend here — this looks more like a unit where weather, migration timing, and hunter effort vary meaningfully year to year, rather than one showing steady herd improvement or decline based on harvest numbers alone.

Hunter numbers have also fluctuated significantly, from a low of 124 hunters afield in 2020 to a high of 294 in 2021, without a clear correlation to success rate — 2021's high hunter count actually produced one of the lower success percentages (13%), while 2020's lower hunter count produced the best success rate in the dataset (25%). This suggests hunter crowding isn't the dominant factor driving success in Unit 500; terrain, weather, and deer distribution likely play bigger roles.

On the trophy side, the counties overlapping Unit 500 carry a moderate history of producing record-class bucks. This isn't a unit with an outsized trophy reputation, but it isn't a blank slate either — hunters willing to put in the physical effort at elevation have a realistic, if not exceptional, shot at a quality mature buck. Given the moderate trophy history and the demanding terrain that likely limits pressure on the best bucks, patient hunters targeting older-age-class animals rather than filling a tag quickly may find this unit more appealing than the raw success percentages suggest.

For hunters who prioritize solitude, physically challenging high-alpine hunting, and a legitimate — if not guaranteed — chance at a good buck, Unit 500 is worth serious consideration. For hunters who want a fast, high-percentage tag-filling experience, the inconsistent success rates here suggest looking elsewhere or coming in with tempered expectations.

Herd Health & Population Trends

The only wildlife survey data available for Unit 500 comes from a single survey year (2024), showing an average buck:doe ratio of 26:100. This is a notably low ratio compared to what's typically considered healthy for a mule deer herd, and with only one survey year on record, it's difficult to say definitively whether this reflects a genuine herd condition or simply the limitations of a single-year snapshot.

A 26:100 buck:doe ratio, if representative of the broader herd trend, would suggest a population skewed heavily toward does relative to bucks — potentially the result of past hunting pressure, winterkill, or predation dynamics common in high-elevation mule deer herds. However, because HuntPilot's data only includes one survey year for this unit, hunters should treat this figure as a data point rather than a definitive trend. A single year of survey data cannot establish whether the ratio is improving, declining, or stable, and hunters relying on this number for decision-making should understand its limitations. Colorado Parks and Wildlife's ongoing survey work will be the better source for tracking whether this ratio holds, improves, or worsens in coming years.

Trophy Quality

Trophy data for Unit 500 indicates a moderate history of record-book production in the counties overlapping this unit. This places Unit 500 in a middle tier — not a unit with a thin or nonexistent trophy pedigree, but also not one of Colorado's headline trophy destinations. Hunters chasing a genuinely exceptional buck should calibrate expectations accordingly: quality bucks exist here, and the rugged, high-elevation terrain likely helps some mature deer survive to older age classes simply due to lower accessibility, but this isn't a unit with a deep or recent track record of exceptional entries.

It's worth remembering that record-book entries are attributed at the county level, not the specific hunt unit, meaning any trophy history connected to Unit 500 is shared with neighboring units that overlap the same counties. A moderate trophy history here reflects the broader area's genetic and habitat quality rather than something unique and exclusive to Unit 500's boundaries.

For hunters whose primary goal is a genuine trophy-caliber buck, Unit 500 offers a realistic shot but not a guarantee, and success will likely hinge on scouting effort, physical capability at elevation, and willingness to pass on younger bucks early in the hunt.

Access & Terrain

Unit 500's terrain is defined by extreme elevation. With a range running from 9,035 feet up to 13,827 feet, this is alpine and subalpine country — think steep basins, exposed ridgelines, and terrain that transitions quickly from timbered slopes to rock and tundra above treeline. Hunters should expect thin air, rapid weather changes, and physically taxing travel regardless of whether they're hunting on foot or using pack stock.

Public land accounts for 72% of the unit's 103,662 acres, giving DIY hunters a solid base of accessible ground to work with. That said, high public land percentage in a unit this rugged doesn't necessarily translate to easy access — much of that public ground likely requires significant hiking or horseback travel to reach productive glassing points and bedding areas, given the elevation profile.

Notably, Unit 500 carries 0% designated wilderness acreage according to available data. This means hunters won't face wilderness-specific access restrictions or motorized-travel limitations tied to a wilderness designation, which can simplify logistics compared to units with heavy wilderness overlap. Hunters can plan their access strategy — whether on foot, horseback, or with legal motorized use on open routes — without the added complexity that wilderness boundaries often introduce.

Given the terrain profile, hunters should prioritize physical conditioning well before the season. Glassing from high vantage points and being prepared to make long, steep stalks across basins and ridgelines will likely be part of any successful strategy here. Hunters can use HuntPilot's mapping tools to overlay public land boundaries and terrain data directly onto Unit 500's boundaries to identify likely glassing points, access routes, and elevation bands worth focusing scouting effort on before the season.

How to Apply

Unit 500 operates entirely on a limited-quota draw system — there is no general season or over-the-counter option available for mule deer in this unit. Every hunter, resident or nonresident, must apply through Colorado's draw process and be awarded a tag before hunting here.

Colorado's deer draw system uses preference points, and both residents and nonresidents accumulate points when they apply and aren't drawn. Colorado's system is a true preference-point draw, meaning hunters holding the highest point totals for a given hunt are awarded tags first, ahead of the general applicant pool. This is not a weighted lottery — a sufficiently high point total in Colorado's system has historically been enough to secure a tag on many hunts, though the exact point level required varies by hunt code, sex, and year.

Nonresidents should expect this unit to require a meaningful point investment given its limited-quota-only structure, though exact point requirements shift from year to year based on tag allocations and application volume. Residents and nonresidents apply through separate pools, and it's worth noting that Colorado sets aside a portion of tags for nonresident applicants under state law, keeping the split defined regardless of how many people apply from either pool.

Application dates, fees, and current draw odds for Unit 500 change every cycle. For the most current numbers, hunters should check HuntPilot's Colorado state page for up-to-date application windows, license costs, and point requirements before applying.

Frequently Asked Questions

What is the terrain like in Unit 500? Unit 500 is high-elevation alpine and subalpine terrain, ranging from 9,035 feet to 13,827 feet. Expect steep basins, exposed ridgelines, and terrain that transitions from timbered slopes to open alpine tundra above treeline. There is no wilderness designation within the unit, which simplifies access planning, but the elevation and slope alone make this physically demanding country requiring strong conditioning.

What is harvest success like in Unit 500? Unit-wide harvest success has ranged from as low as 8% (2022) to as high as 25% (2020) over the past six seasons, with most years falling in the high-teens to low-20s percentage range. There's no consistent upward or downward trend, suggesting success depends heavily on yearly conditions like weather and deer movement rather than a steadily improving or declining herd.

How big are the deer in Unit 500? Trophy records from the counties overlapping Unit 500 show a moderate history of quality buck production. This isn't one of Colorado's premier trophy units, but mature bucks capable of making record-book minimums have come from this area historically. Hunters targeting a genuine trophy buck should expect a realistic but not guaranteed opportunity, and should plan on patient, selective hunting rather than an early-season tag fill.

Is Unit 500 worth applying for? For hunters seeking rugged, high-elevation solitude and a legitimate shot at a quality buck, yes — particularly given the unit's 72% public land base and moderate trophy history. Hunters expecting consistently high success rates should note the wide year-to-year swings in harvest data, from single-digit to mid-20s percentage success, and plan their expectations accordingly. This is a unit best suited to physically capable hunters willing to invest scouting time and effort rather than those seeking a quick, easy tag fill.

What kind of survey data exists for Unit 500's deer herd? Only one year of buck:doe survey data (2024) is available, showing a 26:100 ratio. With just a single year of data, this figure should be treated cautiously rather than as a definitive trend — it's a data point, not a multi-year pattern. Hunters should watch for updated Colorado Parks and Wildlife survey data in future years to see whether this ratio holds or shifts.
