Idaho Unit 48 Mule Deer Hunting Guide

Idaho Unit 48 is a mountainous, public-land-heavy unit that draws attention from mule deer hunters across the region — including a growing number of Oregon and Washington hunters looking for a change of scenery as their home-state deer numbers slide. With elevations ranging from 4,802 to 11,600 feet across 390,089 acres, this is big, vertical country that rewards hunters willing to put in the miles and glass patiently from good vantage points.

At 87% public land, Unit 48 is genuinely DIY-friendly — the vast majority of the unit is open to hunters without needing to negotiate private access. A modest 7% of the unit falls within designated wilderness, which means most of the unit is reachable without the logistical complications that come with heavier wilderness restrictions. This is a unit where a hunter with solid boots, good optics, and a willingness to climb can realistically compete for a mature buck.

This is a general-season unit for mule deer, not a draw-only proposition. General-season hunts here cover antlered and either-sex animals, meaning hunters aren't locked out of buck opportunity by a limited-quota system. Idaho also offers limited-quota draw hunts in Unit 48 that include antlered and either-sex animals for hunters who want to apply for a more controlled hunt experience. Both pathways exist here, and understanding which one fits a hunter's plans matters more than chasing a specific tag type.

Harvest Success Rates

Unit 48 has produced consistent, trackable harvest data over the past four seasons, giving hunters a realistic picture of what to expect before committing to a trip.

• 2025: 4,673 hunters, 1,393 harvested, 30% success
• 2024: 4,551 hunters, 1,400 harvested, 31% success
• 2023: 4,431 hunters, 1,170 harvested, 26% success
• 2022: 3,916 hunters, 1,308 harvested, 33% success

These numbers show a unit that consistently pulls in over 3,900 hunters annually, with hunter numbers trending upward each year — from 3,916 in 2022 to 4,673 in 2025. Success rates have held in a fairly narrow band between 26% and 33% across four seasons, which is a solid, dependable range for a general-season mule deer unit with significant hunting pressure. The dip to 26% in 2023 stands out as the outlier year, while 2022 and 2024 both cleared 30%.

For context, a nearly one-in-three success rate on a general-season unit indicates a healthy, huntable deer population combined with real hunter effort — this isn't a unit where tags go unfilled by the thousands, but it also isn't a slam-dunk either. Hunters should expect competition, especially given the year-over-year increase in hunter numbers, and should plan on covering ground to get away from pressure points.

Trophy Quality

Trophy history for the counties overlapping Unit 48 shows a moderate track record of trophy-class mule deer production. This isn't a unit with a thin or absent trophy record, but it also isn't among the elite trophy units in the region. Hunters should treat Unit 48 as a place where a genuinely good, mature buck is achievable with scouting and patience, rather than a unit where trophy bucks are a near-guarantee.

It's worth noting that record-book entries are logged at the county level, not by hunt unit, so the trophy history associated with Unit 48's overlapping counties is shared with neighboring units in the same county boundaries — the bucks behind those records could have come from anywhere within that broader area. That said, a moderate trophy history combined with a large, high-elevation unit with significant public land access suggests there is real potential for hunters who are willing to get into rougher, less-pressured terrain away from easier access points.

Given the general-season structure and the volume of hunters working this unit each fall, the bucks that reach true trophy class are more likely found at higher elevations and in the more remote pockets of the unit rather than near easy access. Hunters chasing a genuinely big buck should plan on hunting away from the crowds described in hunter forums, where pressure tends to concentrate near easier terrain.

Access & Terrain

Unit 48's terrain is defined by extreme elevation range — from valley floors around 4,800 feet up to peaks near 11,600 feet. This vertical relief means hunters can find dramatically different habitat types within the same unit, from lower sagebrush and timber transition zones to high alpine basins, depending on when and where they hunt during the general season.

With 87% of the unit in public ownership, access is not the limiting factor here that it is in many Idaho deer units — hunters aren't fighting for scraps of walk-in land or negotiating with private landowners for permission. The 7% wilderness designation covers a relatively small portion of the unit, meaning most of Unit 48 is accessible through standard public land travel without the added complexity of wilderness-specific restrictions on motorized access.

That said, the sheer size of the unit at nearly 390,000 acres and the extreme elevation gain mean this is physically demanding country. Hunters accustomed to flatter terrain should be prepared for serious vertical hiking to reach the high country where mature bucks are more likely to hold, especially as the general season progresses and deer respond to pressure by moving into steeper, less accessible terrain. Hunters on forums researching this unit have specifically asked about snow accumulation at elevation and how it affects deer distribution — while unit-specific snow timing isn't available in the data here, hunters should expect early snow at the highest elevations to push deer downward as the season progresses, concentrating animals in mid-elevation transition zones.

Glassing is a viable and often preferred strategy in country like this — the terrain lends itself to spotting scope work from vantage points overlooking basins and open slopes, rather than exclusively spot-and-stalk still-hunting through timber. Hunters willing to sit and glass methodically, then make a calculated approach, tend to do well in unit types like this.

HuntPilot Analysis: Is Unit 48 Worth Applying For?

Unit 48 earns a genuine recommendation for hunters willing to work for their buck. The combination of 87% public land, a large acreage base, and a general-season structure that doesn't lock hunters out of antlered opportunity makes this an accessible unit for both resident and nonresident hunters, including those transitioning from declining deer numbers in neighboring states.

The harvest data tells a straightforward story: success rates in the high-20s to low-30s percent range over four consecutive years show a stable, huntable population without wild swings that would suggest herd instability. Rising hunter participation numbers year over year do suggest this unit is gaining a reputation — which cuts both ways. More hunters means more competition for the same bucks, particularly near easier access points, but it also confirms the unit is producing enough success to keep bringing hunters back.

Trophy quality here is moderate, not exceptional. Hunters chasing a wall-hanger giant should have realistic expectations — Unit 48 can produce a genuinely good mature buck, especially for those willing to hunt hard into the high country, but it isn't a unit with an outsized trophy reputation relative to its neighbors. For hunters prioritizing opportunity, access, and a fair shot at a solid buck over chasing a specific trophy score, this unit checks the right boxes.

The verdict: Unit 48 is worth serious consideration for DIY-minded mule deer hunters, particularly those who value public land access and are physically prepared for steep, high-elevation terrain. It's less suited to hunters expecting an easy, low-effort hunt or guaranteed trophy production — this is a unit where the reward scales with the effort put in.

How to Apply

Idaho's mule deer system in Unit 48 runs on two tracks: general-season tags and limited-quota draw tags, both of which can include antlered and either-sex opportunities.

General-season tags are the more accessible route. Idaho's general deer tags are typically available over the counter for residents and nonresidents alike, subject to statewide tag caps, and don't require a hunter to win a draw to hunt Unit 48 during the general season. This is the pathway most hunters — including the out-of-state hunters referenced in local hunting forums — use to access Unit 48's mule deer hunting.

Limited-quota draw tags in Unit 48 offer a more controlled hunt with capped participation. These require a successful draw application through Idaho's controlled hunt system. Idaho does not use a preference or bonus point system — there are no points to accumulate here. Every application, whether it's a hunter's first year applying or their fifteenth, carries identical odds in that specific year's draw. The only lever hunters have is which hunts they choose to apply for.

Residents and nonresidents both apply through the same random-draw structure for limited-quota tags, though nonresident tag numbers are typically capped separately from resident allocations under Idaho's statewide framework. Because Idaho's system doesn't reward past applicants with better odds, hunters shouldn't wait for "the right year" to apply — every year is a fresh, independent opportunity.

Application dates, fees, and current draw structures change and should never be assumed from prior years. For the most current information on deadlines, fees, and how Unit 48 fits into Idaho's controlled hunt framework, check HuntPilot's Idaho state page and the Unit 48 unit page directly.

Frequently Asked Questions

What is the terrain like in Idaho Unit 48? Unit 48 is defined by significant elevation range, running from roughly 4,800 feet at its lowest points to 11,600 feet at its highest peaks. This creates varied habitat within a single unit, from lower transition zones to high alpine basins. With 390,089 total acres and 87% public land, hunters have substantial room to roam, though the vertical terrain demands solid physical conditioning. A small portion of the unit (7%) falls within designated wilderness.

What is harvest success like in Unit 48? Success rates have ranged from 26% to 33% over the past four seasons (2022–2025), with the most recent two years (2024 and 2025) both landing around 30-31%. Hunter numbers have climbed steadily during this period, from 3,916 in 2022 to 4,673 in 2025, while harvest totals have generally tracked upward as well, peaking at 1,400 in 2024.

How big are the mule deer in Unit 48? Trophy history for the counties overlapping Unit 48 shows a moderate track record of producing trophy-class bucks. This suggests real potential for a mature, quality buck — particularly for hunters willing to hunt remote, high-elevation terrain away from pressure — but it isn't a unit with an outsized reputation for giant bucks compared to the region's top-tier trophy units.

Is Unit 48 worth applying for as a nonresident? For nonresident hunters, Unit 48's appeal lies in its accessible general-season structure, high percentage of public land (87%), and steady, dependable harvest success in the high-20s to low-30s percent range. It's a strong option for hunters who want a fair, honest DIY mule deer hunt without needing to draw a hard-to-get tag, though hunters should be prepared for genuine physical demands and moderate — not extreme — trophy expectations.

Do hunters need to worry about crowding in Unit 48? Rising hunter participation (up from 3,916 in 2022 to 4,673 in 2025) suggests increasing popularity, and hunter forums researching this unit have specifically asked about crowding near easier access points. Hunters willing to push into the unit's higher-elevation, more remote terrain — leveraging the 87% public land base — have the best chance of finding both less pressure and better mature buck opportunity.
