Idaho Unit 43 Elk Hunting Guide

Idaho Unit 43 sits in some of the most rugged, high-elevation country in the state, with terrain ranging from 4,167 feet up to 10,311 feet across 448,263 total acres. For elk hunters weighing whether to put in for this unit, the numbers matter as much as the scenery — and Unit 43 offers a lot to unpack on both fronts. With 99% of the unit in public ownership, access isn't the issue here; the challenge is the terrain itself and what the harvest data says about hunter success.

This is a unit that draws attention from backcountry hunters willing to put in serious miles, and forum chatter consistently points to a rugged, physically demanding hunt where elk sightings can be inconsistent from year to year. Before committing time and application dollars to Unit 43, it's worth looking closely at what the harvest trends, terrain, and application structure actually show.

HuntPilot Analysis: Is Unit 43 Worth Applying For?

Unit 43 is a mixed bag, and hunters should go in with realistic expectations. On the positive side, this is about as close to unrestricted public access as it gets in the West — 99% public land means DIY hunters aren't fighting for landowner permission or dealing with checkerboarded private inholdings. The elevation range, spanning more than 6,000 vertical feet, means there's a wide variety of habitat types to hunt depending on timing and weather, from lower-elevation transition zones to high alpine basins.

The harvest numbers, however, tell a story of a unit trending in the wrong direction. Success rates fell from 14% in 2023 to 12% in 2024 and down to 10% in 2025, even as hunter numbers stayed relatively flat (2,025 to 2,115 to 2,064 hunters over those three years). That's a meaningful decline — a nearly 30% relative drop in success rate over two seasons — and it lines up with anecdotal forum reports describing difficulty finding elk in areas hunters have historically relied on.

Trophy data for the counties overlapping Unit 43 shows a limited history of record-book entries, which suggests this unit is not a destination for hunters chasing a wall-hanger bull. That doesn't mean mature bulls don't exist here, but the data doesn't support recommending Unit 43 as a trophy unit. This is better viewed as an opportunity and experience unit — a place to hunt hard, cover ground, and hope to connect, rather than a unit hunters should bank on for a record-class animal.

Given Idaho's lottery-style draw system (more on that below), the low cost of applying makes Unit 43 a reasonable gamble even with declining success rates, but hunters should temper expectations. This is a unit for those who value rugged, high-elevation public land hunting and don't mind a lower percentage chance of tagging out, rather than a unit for hunters who need a high-probability season to justify the trip.

Harvest Success Rates

The harvest data for Unit 43 covers three recent seasons and shows a clear downward trend:

• 2023: 2,025 hunters, 279 harvested, 14% success
• 2024: 2,115 hunters, 259 harvested, 12% success
• 2025: 2,064 hunters, 215 harvested, 10% success

Hunter participation has remained steady — right around 2,000 to 2,100 hunters each season — but the number of elk harvested has dropped in each of the last two years, from 279 down to 259 and then to 215. That's a decline of roughly 23% in total harvest over two years despite a nearly identical number of hunters afield. This pattern suggests something is putting pressure on elk numbers, vulnerability, or distribution within the unit, rather than simply fewer hunters trying.

For prospective applicants, this trend is worth weighing heavily. A unit with a 10% success rate means the large majority of hunters go home without an animal, and the trajectory here is heading further in that direction rather than stabilizing or improving. Hunters considering Unit 43 should factor this into their expectations and treat it as a lower-odds hunt rather than a numbers-driven sure thing.

Trophy Quality

Trophy record data for the counties overlapping Unit 43 shows a limited history of entries. This points to limited trophy potential for the unit — it has not historically been a strong producer of record-book bulls, and hunters should not go into Unit 43 expecting a high likelihood of encountering a mature, wide-antlered bull worthy of entry-level trophy consideration. That said, limited record-book history doesn't mean an occasional good bull can't be taken; it simply means the data doesn't support marketing this as a trophy destination. Hunters focused on antler size are better served researching units with a stronger track record, while hunters focused on the experience of hunting rugged, high-country public land will find Unit 43 more aligned with what it can realistically offer.

Access & Terrain

Unit 43's defining characteristic is its overwhelming public land access combined with extreme elevation range. At 99% public land, this unit is about as open as it gets for DIY hunters — there's essentially no need to navigate private land access issues or seek landowner permission to hunt the vast majority of the unit.

The elevation gradient, from 4,167 feet at the low end to 10,311 feet at the highest points, means hunters can expect to encounter everything from lower valley bottoms to true high-alpine terrain within the same unit boundary. This wide elevation swing is a double-edged sword: it offers options depending on weather and elk movement, but it also means the unit demands serious physical conditioning and route-planning to access the higher basins where elk often retreat as pressure builds.

Notably, this unit carries 0% wilderness designation, meaning there are no wilderness-area guide requirements to worry about for nonresident hunters — unlike some other Idaho backcountry units. This makes DIY, unguided access straightforward from a legal standpoint, though the physical demands of the terrain remain a factor regardless of wilderness status.

Forum reports from hunters who've spent time in Unit 43 consistently describe it as physically demanding country requiring significant mileage on foot to locate elk, with reports of hiking well over 30 miles across multi-day trips without heavy elk sign in some years. This lines up with the terrain data — a unit with this much vertical relief and public acreage rewards hunters willing to get away from easy access points and cover ground into less-pressured basins and drainages. Hunters planning a trip to Unit 43 should use mapping tools — including HuntPilot's public land and terrain overlays — to identify drainages, water sources, and elevation bands away from the more heavily traveled access corridors before showing up cold.

How to Apply

Idaho's application system is a straightforward lottery — there is no preference point or bonus point system in Idaho. Every application, whether it's a hunter's first year applying or their tenth, carries the same odds as any other applicant in that residency pool. This means there's no benefit to "building points" before applying, and no penalty for jumping in for the first time. The only variable is which hunt and unit combination a hunter chooses to apply for.

Frequently Asked Questions

What is the terrain like in Idaho Unit 43? Unit 43 covers a massive elevation range from 4,167 feet to 10,311 feet across nearly 450,000 acres, almost all of it public land. Expect rugged, high-relief country that transitions from lower valley terrain to true alpine basins at the higher elevations. Forum reports consistently describe this as physically demanding country that requires significant hiking to get away from pressured access points and into productive elk habitat.

What is harvest success like in Unit 43? Recent harvest data shows success rates declining from 14% in 2023 to 12% in 2024 and down to 10% in 2025, even though hunter numbers have stayed fairly consistent at around 2,000 to 2,100 hunters per season. This is a lower-odds unit, and the trend has been moving in the wrong direction over the last two recorded seasons.

How big are the elk in Unit 43? Trophy record data for the counties overlapping this unit shows a limited history of record-book entries, indicating limited trophy potential. Hunters should not expect Unit 43 to be a strong producer of trophy-class bulls based on available data — this is better approached as an opportunity hunt in rugged public country rather than a unit targeted specifically for antler size.

Is Unit 43 worth applying for? It depends on what a hunter is looking for. With 99% public land and no wilderness-related guide requirements, Unit 43 offers straightforward access for DIY hunters willing to hike into rugged terrain. However, declining harvest success (down to 10% in 2025) and limited trophy history mean this unit is best suited to hunters prioritizing the backcountry experience and low-cost application over high odds or trophy potential. Given Idaho's inexpensive, points-free lottery system, it's a reasonable unit to try, but hunters should keep expectations realistic.

Does Idaho use a preference point system for elk draws in Unit 43? No. Idaho has no preference points or bonus points for any species, including elk. Every application is an independent lottery draw — a first-time applicant has identical odds to someone who has applied for years. The only strategic decision hunters make is which unit and hunt to select, not how many points they've accumulated.
