Idaho Unit 23 Elk Hunting Guide

Idaho Unit 23 elk hunting draws consistent interest from both resident and nonresident hunters looking at west-central Idaho's rugged, canyon-cut country near Riggins. Spanning 476,571 acres with elevations ranging from a low 1,728 feet along the river breaks up to 9,276 feet in the high country, Unit 23 offers a dramatic vertical range that shapes everything about how elk use the landscape and how hunters need to approach the terrain.

With 76% of the unit in public ownership, Unit 23 is a legitimate option for do-it-yourself hunters who don't want to lease private ground or hire an outfitter. Only 2% of the unit falls within designated wilderness, meaning the vast majority of huntable terrain is accessible without the guide requirements that apply in more wilderness-heavy Idaho units. That combination of public access and moderate wilderness footprint makes Unit 23 one of the more approachable elk units in this part of the state for hunters willing to put in the legwork on foot.

This article breaks down what the data shows on harvest performance, trophy potential, and how to apply for Unit 23 elk tags, using figures sourced through HuntPilot's unit database.

HuntPilot Analysis: Is Unit 23 Worth Applying For?

Unit 23 sits in a reasonable middle ground — not a slam-dunk unit, but a legitimate option depending on what hunters are after. The harvest numbers show a unit with real elk density and consistent hunter participation: in 2025, 4,942 hunters harvested 909 elk for an 18% success rate, and in 2024, 5,412 hunters harvested 925 elk for a 17% success rate. Those numbers point to a stable, moderately productive unit year over year rather than a unit in decline or a boom-and-bust situation.

The 76% public land figure is a major point in this unit's favor. DIY-minded hunters can find plenty of huntable ground without needing to negotiate private access, and the low 2% wilderness designation means nonresidents can hunt the large majority of the unit without being forced into a guide requirement. The elevation spread — from river-bottom terrain near 1,700 feet up to nearly 9,300 feet — gives elk a lot of vertical country to disperse across, which explains both the moderate success rates and the value of scouting multiple elevation bands rather than fixating on one drainage.

Trophy-wise, the counties overlapping Unit 23 carry a moderate history of trophy-class elk in record-book data. That places this unit below the handful of truly elite Idaho trophy units, but it's not devoid of trophy potential either — hunters willing to get into the steep, less-pressured pockets of the unit have a realistic shot at a mature bull, even if record-book-caliber animals are the exception rather than the rule.

For hunters weighing whether to apply: Unit 23 makes sense as a solid opportunity-focused elk unit with decent public access and dependable harvest performance. It's not the unit to target if trophy score is the only priority, but as a well-rounded option with strong access and consistent success rates, it earns a place on the shortlist for both resident and nonresident applicants.

Harvest Success Rates

Unit 23's harvest data shows a unit that produces results at a steady clip. In 2025, hunter participation totaled 4,942 with 909 elk harvested, a unit-wide success rate of 18%. The prior year, 2024, saw slightly higher participation at 5,412 hunters with 925 harvested, translating to a 17% success rate.

The consistency between these two years — both in the number of hunters afield and the resulting success percentage — suggests Unit 23 isn't experiencing dramatic swings in elk availability or hunting pressure. An 18% unit-wide success rate is respectable for a general elk unit of this size and terrain complexity, especially given the unit draws thousands of hunters each season. Hunters should note this is a unit-wide figure across all hunt types and doesn't break down by specific hunt code, so individual hunt opportunities within the unit may perform above or below this average depending on hunt structure and timing.

Trophy Quality

Trophy record data for the counties overlapping Unit 23 shows a moderate history of trophy-class bulls. This isn't a unit associated with a deep or standout trophy pedigree, but it also isn't blank on the record books — moderate trophy history means hunters can find mature bulls in this country, particularly in the more remote, higher-elevation pockets away from road access and hunting pressure.

It's worth noting that record-book entries are logged at the county level, not by specific hunt unit, so the trophy data reflecting Unit 23's overlapping counties is shared with neighboring units in the same county boundaries. A bull entered into the record books from this general area could have been taken in Unit 23 or in an adjacent unit within the same county. Given that caveat, hunters targeting genuine trophy potential in Unit 23 should treat this as a solid, workmanlike elk unit rather than a destination trophy unit — most bulls taken here will be respectable, mature animals rather than record-book contenders, and hunters chasing the biggest bulls in Idaho should look at units with a stronger, more concentrated trophy history.

Access & Terrain

Unit 23's terrain is defined by extreme vertical relief. The elevation range runs from 1,728 feet at the lowest river-bottom country up to 9,276 feet at the highest peaks, a spread of more than 7,500 feet within the unit boundary. This kind of vertical diversity means elk can be found in dramatically different habitat types depending on the time of year and weather — from steep canyon breaks and brushy river drainages at lower elevations to high alpine basins and timbered ridgelines up top.

With 76% of the unit's 476,571 acres in public ownership, hunters have room to roam without needing to secure private land permission for the majority of their hunt. The low 2% wilderness designation is notable: it means Unit 23 doesn't carry the same access restrictions or guide requirements that heavily-wilderness Idaho units impose, making it more approachable for self-guided hunters willing to hike into steep, remote terrain on public land.

Given the canyon country nature of this part of west-central Idaho, hunters should expect physically demanding terrain — steep grades, significant elevation gain and loss between glassing points, and country that rewards hunters willing to get well off any road system. Public land access combined with minimal wilderness restriction gives DIY hunters real flexibility to plan routes based on where they're willing to hike rather than where they can gain private permission.

How to Apply

Idaho's controlled hunt draw operates as a straightforward lottery system with no preference points or bonus points involved. Every application — whether it's a hunter's first year applying or their tenth — carries the same odds as any other applicant for a given hunt. There's nothing to build or accumulate; the only strategic lever available is which hunts a hunter chooses to apply for.

This timeline applies to both resident and nonresident applicants, though the fees differ substantially by residency:

Frequently Asked Questions

What is the terrain like in Idaho Unit 23?

Unit 23 features extreme elevation variation, ranging from 1,728 feet in the lower river-bottom country up to 9,276 feet in the high country — a difference of more than 7,500 vertical feet across the unit. This creates a mix of steep canyon terrain, brushy drainages at lower elevations, and timbered high country and alpine basins near the top of the elevation range. With 76% of the unit's 476,571 acres in public ownership, hunters have substantial room to explore this vertical terrain without needing private land access, though the steep, rugged nature of the country makes for physically demanding hunts.

What is harvest success in Unit 23?

Recent harvest data shows Unit 23 producing an 18% unit-wide success rate in 2025 (909 elk harvested among 4,942 hunters) and a 17% success rate in 2024 (925 elk harvested among 5,412 hunters). These figures represent unit-wide totals across all hunt types rather than a single hunt code, and the year-over-year consistency suggests a stable elk population and hunting pressure dynamic in this unit.

How big are the elk in Unit 23?

Trophy record data for the counties overlapping Unit 23 indicates a moderate history of trophy-class bulls. This places Unit 23 below Idaho's elite trophy units, but mature bulls are present, particularly in more remote or higher-elevation terrain away from hunting pressure. Hunters should set realistic expectations: this unit is better characterized as a solid, dependable elk unit rather than a dedicated trophy destination.

Is Unit 23 worth applying for?

Based on the available data, Unit 23 is worth considering for hunters prioritizing access and consistent opportunity over trophy potential. The 76% public land figure and minimal 2% wilderness designation make it approachable for DIY hunters, and harvest success rates in the high-teens percentage range over the past two seasons show dependable performance. Hunters chasing record-book bulls exclusively may want to look elsewhere, but those seeking a well-rounded elk hunt with strong public access will find plenty to like here.

Does Idaho use a preference point system for Unit 23 elk tags?

No. Idaho's controlled hunt draw is a pure lottery with no preference points or bonus points of any kind. Every applicant, regardless of how many years they've applied, has identical odds on any given hunt in Unit 23 or elsewhere in the state. The only strategy available to hunters is choosing which specific hunts to apply for, since there's no point accumulation to leverage over time.
