Colorado Unit 19 Elk Hunting Guide

Colorado Unit 19 is a limited-quota elk unit spanning 270,820 acres of high-elevation country, with terrain ranging from 4,843 feet up to 12,687 feet. For elk hunters researching this unit, the defining fact is simple: there is no general season here. Every elk hunt in Unit 19 — including hunts for antlered and either-sex animals — is a limited-quota draw hunt, which changes how hunters should think about both opportunity and pressure compared to nearby over-the-counter units.

With 70% public land and 30% of the unit falling within designated wilderness, Unit 19 offers hunters a substantial base of accessible ground, but also a meaningful chunk of country that requires backcountry-style logistics — foot or stock access, extended pack-out planning, and the physical demands of hunting at elevation. This is not a unit where hunters roll up to a trailhead and walk a quarter mile to a meadow. The elevation spread alone, from valley floor to well above 12,000 feet, tells hunters this unit rewards those willing to get away from roads and climb.

Because every hunt here runs through the draw, Unit 19 tends to see more controlled hunter numbers than comparable OTC units nearby — a dynamic that shows up directly in the harvest data below.

Harvest Success Rates

Unit 19's harvest data over the past four seasons shows a unit with real, if modest, elk hunting success paired with declining hunter turnout:

• 2025: 766 hunters, 102 elk harvested, 13% success
• 2024: 2,280 hunters, 238 elk harvested, 10% success
• 2023: 1,976 hunters, 201 elk harvested, 10% success
• 2022: 1,979 hunters, 147 elk harvested, 7% success

Two trends stand out. First, success rates have been on an upward trajectory, climbing from 7% in 2022 to 13% in 2025. Second, and more striking, is the drop in hunter numbers — from nearly 2,300 hunters in the field in 2024 down to 766 in 2025, a reduction of roughly two-thirds. That kind of swing in hunter numbers on a limited-quota unit typically reflects a reduction in tags allocated for that draw cycle, which in turn helped push success rates higher with fewer people competing for the same elk. Hunters should not assume 13% is now the new baseline — it's worth checking HuntPilot's current data on tag numbers for the specific hunt code and season structure being applied for, since success rates in a draw unit like this are directly tied to how many tags are issued in a given year.

Overall, these numbers put Unit 19 in a realistic, working-unit category — not an easy-money unit, but one where hunters willing to put in scouting time and physical effort have a legitimate shot, especially in years with lower hunter density.

Trophy Quality

Trophy record data for the counties overlapping Unit 19 shows a moderate history of trophy-class elk production. This is not one of the elite units in Colorado that regularly produces top-tier record-book bulls, but the historical record does show that quality animals have come from this general area over time. Because trophy entries are logged at the county level rather than by specific unit boundary, the moderate trophy history associated with this area is shared with neighboring units that overlap the same counties — it should be read as a regional indicator rather than a Unit 19-exclusive statistic.

For hunters chasing an exceptional bull, this data suggests Unit 19 is a solid, honest hunt rather than a unit known for producing standout trophy animals. The wilderness component (30% of the unit) and the demanding elevation range do offer the kind of remote, difficult-to-access country where mature bulls can escape pressure — and forum accounts from hunters in similar high-country Colorado terrain consistently point to elk holding in the 10,000–11,000 foot range, well off roads, in meadow-to-dark-timber transition zones near aspen stands and small water sources during the hunt. That kind of terrain does tend to protect older bulls from easy pressure, which aligns with a moderate-but-real trophy history rather than a unit devoid of mature animals.

Herd Health & Population Trends

Wildlife survey data collected across six survey years from 2018 to 2024 shows an average bull-to-cow ratio of 25:100 for Unit 19. This is a relatively low ratio by elk population management standards, and it's a number hunters should take seriously when setting expectations. A 25:100 ratio indicates a herd with a smaller proportion of bulls relative to cows than many trophy-oriented units carry, which typically correlates with higher hunting pressure on bulls relative to the available bull population, lower average bull age structure, or both.

This ratio is consistent with — not contradictory to — the moderate trophy history and the harvest success rates discussed above. A unit with a lower bull:cow ratio will generally produce more encounters with younger bulls and fewer mature, trophy-class animals in the population at any given time. Hunters targeting this unit should calibrate expectations accordingly: this looks like a unit that can produce a solid, mature bull with the right effort and terrain knowledge, but it is not carrying the kind of bull-heavy demographic that some limited, harder-to-draw units in the state maintain.

Access & Terrain

Unit 19 offers 70% public land, which gives DIY hunters a strong base of accessible ground to hunt without needing to negotiate private land access. That said, hunters should recognize that public land accessibility and ease of access are two different things here — with 30% of the unit designated wilderness and elevations climbing to nearly 12,700 feet, a meaningful portion of the public land in this unit is genuinely rugged, high-elevation backcountry.

The elevation range of 4,843 to 12,687 feet spans an enormous vertical gradient, and hunters should plan their approach around where in that range they intend to hunt. Lower elevations near the valley floor will offer easier physical access but likely more hunting pressure and more accessible terrain for other hunters as well. The upper end of that range — the alpine and subalpine zones above 10,000 feet — is where hunters willing to hike or use stock access can find the kind of isolation that tends to hold mature bulls later into the season, particularly as elk transition off summer range.

Because Colorado does not impose Wyoming-style wilderness guide requirements, nonresident hunters are free to hunt Unit 19's wilderness acreage without hiring an outfitter. That's a meaningful advantage for DIY-minded hunters willing to do the physical work of packing into the 30% wilderness portion of the unit, though it also means hunters should be self-sufficient with navigation, water sourcing, and pack-out logistics if hunting deep into that terrain.

HuntPilot Analysis: Is Unit 19 Worth Applying For?

Based on the data available through HuntPilot, Unit 19 is a reasonable, mid-tier limited-quota elk unit — worth applying for if a hunter's goals are aligned with what the numbers actually show, but not a unit to chase purely for trophy potential.

The case for applying: success rates have trended upward over the last several years, landing at 13% in 2025, and the unit carries a large footprint of public land (70%) with genuine backcountry character in its wilderness acreage. The fact that every hunt here runs through a limited-quota draw — rather than an over-the-counter free-for-all — means hunter density is controlled by the state, which tends to produce a better on-the-ground experience than crowded OTC units nearby, a dynamic echoed in forum discussions where hunters note that OTC units "will all be crowded." Because every path into this unit's elk hunting runs through the draw, hunters get the benefit of a managed hunter population even on hunts for antlered or either-sex animals.

The case for tempering expectations: the average bull:cow ratio of 25:100 is on the lower end, and the trophy history for the surrounding counties is moderate rather than exceptional. Hunters should not walk into Unit 19 expecting a shot at an elite bull. This is a unit best suited to hunters who want a genuine backcountry Colorado elk experience with a fair chance at harvesting a mature bull, rather than hunters specifically chasing record-book potential.

The sharp decline in hunter numbers from 2024 to 2025 (2,280 down to 766) is also worth flagging — it likely reflects a reduction in tags issued, and hunters should check current quota and draw odds information on HuntPilot before assuming recent success rates will hold steady into future seasons.

How to Apply

Colorado's elk hunts operate on a true preference-point draw system. Colorado is not a weighted lottery — hunters who accumulate the highest number of preference points in a given pool are guaranteed to draw ahead of lower-point applicants, meaning a high enough point total can effectively guarantee a tag over time. Because Unit 19 offers no general season and runs entirely through limited-quota hunts, every hunter pursuing elk here — resident or nonresident — must apply through Colorado's draw system rather than buying an OTC license.

Residents and nonresidents apply through separate pools, and nonresidents should expect a more competitive path given the split allocation between the two groups. Because a successful draw consumes the preference points a hunter has accumulated for that species, hunters who draw a Unit 19 elk tag will restart their point total for future applications.

Given the moderate trophy history and workable success rates in this unit, it's a reasonable target for hunters at a range of point levels rather than one reserved exclusively for maximum-point applicants — but the only way to know current draw odds for the specific hunt code a hunter is considering is to check live numbers.

Application dates, fees, and current draw odds change every cycle. For up-to-date deadlines, costs, and draw statistics specific to Unit 19, see HuntPilot's Colorado state page at /states/CO.

Frequently Asked Questions

What is the terrain like in Colorado Unit 19? Unit 19 covers a massive elevation range, from 4,843 feet up to 12,687 feet, across 270,820 acres. That spread includes lower valley terrain as well as true high-alpine country, with 30% of the unit designated wilderness. Hunters should expect steep, physically demanding ground in the upper elevations and more moderate terrain lower down, with 70% of the unit's total acreage in public ownership.

What is harvest success like in Unit 19? Recent harvest data shows success rates of 13% in 2025, 10% in both 2024 and 2023, and 7% in 2022. Success has trended upward in recent years, though hunter numbers dropped substantially between 2024 and 2025, which likely influenced the higher 2025 success rate. Hunters should check HuntPilot for current-year tag numbers before assuming the trend will continue.

How big are the elk in Unit 19? Trophy records for the counties overlapping Unit 19 show a moderate history of trophy-class elk, shared with neighboring units in the same county boundaries. Combined with a survey-measured bull:cow ratio averaging 25:100 across six years of data (2018–2024), Unit 19 looks like a unit capable of producing mature bulls but not one known for consistently elite trophy production.

Is Unit 19 worth applying for? For hunters seeking a legitimate backcountry Colorado elk hunt with reasonable success rates and a large public-land base, yes — Unit 19 offers a workable draw-based hunt with improving success percentages. Hunters specifically chasing top-end trophy potential may want to weigh the moderate trophy history and lower bull:cow ratio against units with stronger trophy pedigrees before committing points.

Do nonresidents need a guide to hunt the wilderness portion of Unit 19? No. Colorado does not require nonresident hunters to hire an outfitter or guide to hunt wilderness areas, unlike Wyoming. Nonresidents can hunt the 30% wilderness portion of Unit 19 DIY, though they should be prepared for the physical and logistical demands of backcountry access at elevations reaching nearly 12,700 feet.
