Colorado Unit 88 Pronghorn Antelope Hunting Guide

Colorado Unit 88 is a limited-quota pronghorn unit located on the eastern plains, offering hunters a draw-only opportunity to pursue antelope across nearly 440,000 acres of mixed public and private ground. With no general season available, every hunter afield in Unit 88 has gone through Colorado's draw process to secure a tag, and recent harvest numbers show this unit consistently produces solid results for those who draw.

This article breaks down what hunters need to know before applying for Unit 88 — from harvest trends and herd data to terrain realities and trophy potential — using data compiled by HuntPilot to give an honest picture of what this unit offers.

Unit Overview

Unit 88 sits at a relatively low elevation band of 4,416 to 5,565 feet, typical of the plains and prairie country that defines much of Colorado's pronghorn range. The unit spans 439,219 acres, but only 21% of that ground is public, meaning the majority of Unit 88 is private land. There is no wilderness acreage in this unit, so access considerations here revolve entirely around public-private land boundaries rather than backcountry pack-in logistics.

Because every hunt in Unit 88 runs through the draw — there is no over-the-counter or general season option — hunters need to treat this as a true limited-entry unit. That includes tags covering antlered and either-sex pronghorn, giving drawn hunters a legitimate shot at a buck rather than being funneled into a doe-only management hunt.

Harvest Success Rates

Harvest data for Unit 88 shows consistently strong success rates over the past five years, which is typical for pronghorn hunts where animals are visible across open terrain and hunter effort translates directly into opportunity.

• 2025: 259 hunters, 135 harvested — 52% success
• 2024: 621 hunters, 360 harvested — 58% success
• 2023: 569 hunters, 334 harvested — 59% success
• 2022: 715 hunters, 387 harvested — 54% success
• 2021: 453 hunters, 212 harvested — 47% success

Success rates have held in the high-40s to high-50s range across five seasons, with 2023 and 2024 representing the strongest years at 59% and 58% respectively. The drop in both hunter numbers and success in 2025 (259 hunters, 52%) is worth noting — it may reflect a reduced quota that year, but the success percentage itself remained solidly in line with the unit's recent average. Overall, hunters who draw a tag in Unit 88 have a better-than-coin-flip chance of filling it, which is a meaningful data point for anyone deciding whether to apply.

Trophy Quality

Trophy history for the counties overlapping Unit 88 points to a moderate trophy record. This isn't a unit with a deep, decades-long reputation for pumping out record-book pronghorn, but it has produced qualifying animals over time. Hunters should treat Unit 88 as a unit where a mature, respectable buck is a realistic goal, while an exceptional or record-class animal would be a bonus rather than an expectation.

Given the moderate trophy history and the private-land-heavy composition of the unit, the more consistent play for most hunters here is a quality, mature buck rather than chasing a specific score. Hunters focused purely on trophy potential may want to weigh Unit 88 against other units with a deeper trophy pedigree, but for a solid, attainable buck combined with strong harvest odds, this unit performs well.

Herd Health & Population Trends

Survey data collected across six years (2018–2024) shows an average buck-to-doe ratio of 40:100 in Unit 88. That's a healthy, believable ratio for a pronghorn herd — well within the normal range biologists expect to see in a functioning population, and it doesn't carry any of the red flags associated with small, unreliable sample sizes. A 40:100 ratio suggests a reasonably balanced herd structure with enough mature bucks in the population to support a quality hunt, which aligns with the moderate trophy potential and solid harvest success numbers discussed above.

This is a good sign for hunters weighing whether to invest points or apply in Unit 88 — the herd isn't being over-harvested to the point where buck numbers are collapsing, and the multi-year average gives more confidence than a single-year snapshot would.

Access & Terrain

Access is the single biggest planning factor for Unit 88. With only 21% of the unit's 439,219 acres classified as public land, the majority of this unit is private property. That reality shapes everything about how a hunt here needs to be planned. Hunters relying purely on public ground will be working with a smaller footprint than the unit's overall size suggests, and finding public parcels with good pronghorn habitat and reasonable access points takes real scouting effort — echoed in forum discussions of hunters here noting that public chunks can come with limited access points, pushing hunters to cover ground on foot once they're in.

There is no wilderness acreage in Unit 88, so there are no backcountry access restrictions to worry about — this is prairie and plains country, not alpine terrain. Elevation across the unit is modest and consistent, ranging from 4,416 to 5,565 feet, which means hunters won't be dealing with significant elevation gain or altitude issues. The terrain itself is typical eastern-plains pronghorn habitat: open, rolling ground with visibility that favors long-range spotting and stalking tactics over still-hunting.

Given the public land percentage, hunters should plan carefully before the season to identify which public parcels are actually huntable and accessible, rather than assuming the unit's large total acreage translates into abundant public opportunity. Landowner relationships and paid-access programs are common in Colorado pronghorn country, so hunters should budget time to research access options beyond public ground if they want more flexibility.

HuntPilot Analysis: Is Unit 88 Worth Applying For?

Based on the data, Unit 88 is a reasonable unit to target for hunters prioritizing harvest success and herd health over trophy size. The five-year harvest success trend — consistently in the high-40s to high-50s percentile — is a strong indicator that drawn hunters have a good chance of filling their tag, which matters when application points and effort are on the line. The 40:100 buck-to-doe ratio, sustained across a six-year survey window, also suggests a stable, well-managed herd rather than one riding a boom-bust cycle.

Where Unit 88 falls short is access. At just 21% public land, DIY hunters need to go in with realistic expectations — this is not a unit where hunters can expect to freely roam vast tracts of public ground. Successful hunts here will likely require either securing access to private land, focusing tightly on the public parcels that do exist, or being willing to put in scouting legwork well before the season to map out where huntable public ground actually sits relative to access points.

Trophy potential is moderate, not exceptional. Hunters chasing a record-class buck may want to compare Unit 88 against units with deeper trophy pedigrees before committing points here. But for hunters who want a good chance at filling a tag on a mature, respectable pronghorn in typical eastern Colorado plains terrain, Unit 88's harvest and herd data make a credible case for application.

The bottom line: this unit rewards hunters who do their access homework. It's not a walk-up unit, but the numbers support it as a solid, if not flashy, choice.

How to Apply

Colorado's pronghorn program for Unit 88 is entirely draw-based — there is no general season or over-the-counter option here, so every hunter needs to go through the state's limited-quota application process to hunt this unit.

Colorado uses separate application pools and rules for residents and nonresidents, and pronghorn draw odds are influenced by preference points, which accumulate for hunters who apply but don't draw in a given year. Colorado's system is a true preference-based draw, meaning point totals carry real weight — but the exact odds at each point level shift from year to year based on quota changes and applicant volume, so hunters should check current numbers before applying rather than relying on historical assumptions.

Both residents and nonresidents apply through the same state system, though nonresidents should expect more competitive odds given demand for Colorado pronghorn tags generally. Application requires selecting unit and hunt-code preferences, and hunters who don't draw are typically credited with a preference point toward future applications.

Application dates, fees, and current draw odds change every cycle. For the most current deadlines, fees, and unit-specific draw data for Unit 88, visit HuntPilot's Colorado state page at /states/co.

Frequently Asked Questions

What is the terrain like in Unit 88? Unit 88 is classic eastern Colorado plains and prairie country, with elevation ranging from 4,416 to 5,565 feet — low and consistent, without the elevation gain or alpine conditions found in Colorado's mountain units. There's no wilderness acreage in the unit, so terrain is open and rolling, well-suited to the long-range spotting and stalking tactics typical of pronghorn hunting.

What is harvest success like in Unit 88? Harvest success has been strong and consistent, ranging from 47% to 59% over the past five years (2021–2025). The most recent two years prior to 2025 (2023 and 2024) posted the highest success rates at 59% and 58% respectively, while 2025 saw a smaller hunter turnout of 259 with 52% success. Overall, hunters who draw a tag here have solid odds of filling it.

How big are the pronghorn in Unit 88? Trophy history for the counties overlapping Unit 88 points to moderate trophy potential — the unit has produced quality bucks over time, but it doesn't carry a heavyweight reputation for consistently producing record-class animals. Hunters should expect a realistic shot at a mature buck, with an exceptional or record-book animal being a bonus rather than the norm.

Is Unit 88 worth applying for? Yes, for hunters prioritizing a good chance at filling a tag on a mature pronghorn. The unit's harvest success rates (routinely in the 50-60% range) and a healthy 40:100 buck-to-doe ratio across six survey years both point to a stable, well-managed herd. The main caveat is access — with only 21% public land, hunters need to plan carefully around private ground before applying.

What should hunters know about access in Unit 88 before applying? With 21% public land across 439,219 total acres, the majority of Unit 88 is private property. Hunters need to identify accessible public parcels ahead of time rather than assuming the unit's large footprint means abundant public opportunity. There's no wilderness acreage, so access challenges here are about land ownership boundaries, not backcountry terrain — securing landowner permission or paid access can meaningfully expand a hunter's options in this unit.
