Idaho Unit 73A Mule Deer Hunting Guide

Idaho Unit 73A sits in the southeastern part of the state and offers hunters a mix of general-season opportunity and limited-quota draw hunts for mule deer. Spanning 362,291 acres with elevations ranging from 4,370 to 8,718 feet, this unit presents a broad vertical landscape that pushes deer through multiple habitat types across the season. With 52% of the unit in public ownership, there's meaningful access for hunters willing to do the legwork, though private land still makes up nearly half the acreage.

Unlike many limited-entry units in the West, Unit 73A is not a draw-only proposition. General-season hunts exist here for antlered and either-sex deer, meaning resident and nonresident hunters alike can plan a hunt without needing to win a lottery first. Limited-quota draw hunts are also available, also covering antlered and either-sex animals, giving hunters a second avenue into the unit if they're willing to apply. This dual structure makes 73A worth a close look for hunters evaluating both accessibility and hunt quality in Idaho's mule deer country.

Recent harvest data pulled from HuntPilot shows a unit that swings meaningfully year to year, a pattern worth understanding before committing to a season here.

HuntPilot Analysis: Is Unit 73A Worth Applying For?

The honest answer is: it depends on what a hunter is looking for, and the harvest numbers tell a clear story about variability. In 2024, 1,872 hunters pursued deer in 73A and posted a 32% success rate with 591 animals harvested — a strong year by any measure. The following season, 2025, saw hunter numbers drop sharply to 663, with success falling to 14% and only 92 deer taken. That's a steep swing, and it suggests either a tougher season, reduced tag numbers, changing conditions, or some combination of the three.

Looking at the broader five-year window helps smooth out that noise. Success rates have ranged from a low of 14% (2025) to a high of 32% (2024), with 2022 posting 28% success across 2,044 hunters and 577 harvested animals, 2023 landing at 20% success with 397 harvested, and 2021 coming in at 22% success across 1,002 hunters. The unit has historically supported hunter numbers well over 1,000 in most years, which signals it absorbs pressure reasonably well without collapsing success rates to single digits — except in that anomalous 2025 season.

For trophy quality, the counties overlapping Unit 73A carry a moderate history of trophy-class mule deer production. That's not a unit with an elite, headline-grabbing trophy pedigree, but it has produced quality bucks over time and shouldn't be dismissed by hunters looking for a mature deer. Given that record-book entries are logged at the county level and shared among all units within those boundaries, hunters should treat this as a regional indicator rather than a 73A-specific guarantee — animals credited to these counties could have come from any neighboring unit sharing that boundary.

Overall, Unit 73A is worth applying for if a hunter values flexibility — the ability to hunt general season without guaranteed draw success, backed by a limited-quota option for those wanting to try for better odds or sex-specific hunts. It's not a unit to chase purely for trophy potential, but it's a legitimate, moderately productive deer unit with real public access and a track record of putting hunters on animals in most years.

Harvest Success Rates

The five-year harvest trend for Unit 73A looks like this:

• 2025: 663 hunters, 92 harvested, 14% success
• 2024: 1,872 hunters, 591 harvested, 32% success
• 2023: 2,023 hunters, 397 harvested, 20% success
• 2022: 2,044 hunters, 577 harvested, 28% success
• 2021: 1,002 hunters, 221 harvested, 22% success

The average success rate across these five seasons lands in the low-to-mid 20% range, with 2024 standing out as the best year and 2025 as a clear outlier on the low end. Hunter participation has also varied substantially, from just over 600 hunters in 2025 to more than 2,000 in both 2022 and 2023. This tells hunters two things: first, that 73A can produce solid success in good years, and second, that conditions (weather, migration timing, tag allocation adjustments) can swing outcomes significantly from one season to the next. Hunters should not assume any single year's numbers — especially the most recent one — represent the unit's baseline performance without considering the broader trend.

Trophy Quality

Trophy data for the counties overlapping Unit 73A indicates a moderate history of record-book production. This means mature, quality bucks have come out of this region over time, but it's not a unit defined by an exceptional or elite trophy reputation. Hunters chasing a genuine trophy-class buck can find one here with time and effort, but should calibrate expectations accordingly — this is not a unit where record-book bucks are a routine occurrence.

Forum chatter from hunters in the broader region echoes this moderate characterization, with some reporting bucks in the 150-inch class turning up for those willing to cover ground and stay persistent through the season. That matches the qualitative trophy picture: solid, attainable bucks exist, but hunters need to put in time rather than expect to stumble onto a giant in the first few hours of a hunt.

As always with county-level trophy data, the records attributed to this region are shared with neighboring units that overlap the same counties. A trophy buck credited to this area could have been taken anywhere within that broader boundary, not necessarily within 73A's specific footprint.

Access & Terrain

Unit 73A covers a substantial elevation gradient, from 4,370 feet up to 8,718 feet, which means hunters can expect everything from lower-elevation sagebrush and foothill terrain to higher mountain country depending on where and when they hunt. This vertical range is significant — deer will use different elevation bands depending on weather, forage, and pressure, and hunters who understand how to read that gradient across the season will have an edge over those who park in one spot and wait.

With 52% public land, just over half of the unit's 362,291 acres is open to hunters without needing private landowner permission. That's a workable number for DIY hunters, but it also means nearly half the unit is private, so access planning matters. Hunters should use mapping tools — including HuntPilot's own public land overlays — to identify exactly where the public blocks sit relative to access points before heading out, rather than assuming contiguous public access throughout the unit.

There is no wilderness designation within Unit 73A (0% wilderness), meaning hunters won't encounter the access restrictions or guide requirements sometimes associated with wilderness areas in other western states. This makes the unit fully accessible to self-guided hunters navigating public and private boundaries on their own.

Forum discussions from hunters in nearby Idaho units reinforce a common theme across this part of the state: deer distribution isn't always even across a unit's acreage, and hunters willing to move beyond the easiest access points tend to find better hunting away from concentrated pressure. While specific landmarks mentioned in unrelated unit discussions don't apply directly to 73A, the general lesson holds — covering ground and avoiding the obvious pull-off spots is often the difference between seeing pressured deer and finding undisturbed ones.

How to Apply

Idaho's deer hunting structure in Unit 73A includes both general-season and limited-quota draw opportunities, which gives hunters more than one path into the unit.

General season hunts are available over the counter or through a simplified tag purchase process (depending on residency), covering antlered and either-sex deer. This is the most straightforward way for both resident and nonresident hunters to secure a tag in 73A without entering a draw.

Limited-quota draw hunts also exist in this unit, covering antlered and either-sex deer, for hunters who want to apply for potentially different season structures or hunt conditions than the general season offers. These draw hunts require an application through Idaho's draw system, and hunters should check both resident and nonresident application pools, since Idaho's draw operates as a pure random lottery — there are no preference or bonus points in Idaho. Every applicant, whether applying for the first time or the fifteenth, has identical odds in a given year. The only meaningful strategy is choosing which hunts to apply for, since there's nothing to "build" toward over time.

Residents and nonresidents should both check current license and tag requirements before applying, as the specific application structure can vary by year. Application dates and fees change every cycle. For the current deadlines, fees, and draw odds, see HuntPilot's Idaho page at /states/ID, or visit the Idaho Department of Fish and Game's official site for the published regulations.

Frequently Asked Questions

What is the terrain like in Unit 73A? Unit 73A spans a wide elevation range from 4,370 feet to 8,718 feet, giving hunters access to lower-elevation terrain as well as higher mountain country within the same unit boundary. This vertical diversity means deer behavior and location can shift significantly depending on weather and time of season, and hunters should be prepared to adjust elevation bands as conditions change throughout the hunt.

What is harvest success like in Unit 73A? Success rates have varied considerably over the past five years, ranging from a low of 14% in 2025 to a high of 32% in 2024. The years in between — 2023 (20%), 2022 (28%), and 2021 (22%) — suggest an average success rate in the low-to-mid 20% range is a more reliable expectation than any single recent year. Hunters should view 2025's low numbers as part of a broader fluctuating trend rather than the new normal.

How big are the mule deer in Unit 73A? Trophy records from the counties overlapping this unit show a moderate history of quality buck production. This isn't a unit with an elite trophy reputation, but mature bucks are present and attainable for hunters willing to invest time and cover ground. Expectations should be calibrated toward a solid, attainable buck rather than a guaranteed trophy-class animal.

Is Unit 73A worth applying for? Yes, with realistic expectations. The unit offers both general-season and limited-quota draw access, more than 362,000 acres of hunting ground, and just over half of that (52%) in public ownership. Harvest success has been solid in some years and weak in others, so hunters should treat the five-year average as the more dependable guide rather than fixating on the most recent season alone. It's a good option for hunters who want flexibility and reasonable access without needing to win a hard-to-draw tag.

Is Unit 73A a good unit for public land hunters? With 52% public land across the unit, there is meaningful public access, but private land still covers nearly half the acreage. DIY hunters should use detailed mapping tools — such as HuntPilot's public land layers — to identify exactly where public parcels lie before planning routes, rather than assuming free rein across the entire unit footprint.
