Idaho Unit 40 Elk Hunting Guide

Idaho Unit 40 represents one of the state's most accessible elk hunting opportunities for both residents and nonresidents. Spanning nearly 1.5 million acres across south-central Idaho, this expansive unit offers hunters substantial public land access and consistent harvest opportunities. With 80% public land and zero wilderness restrictions, Unit 40 provides DIY hunters the freedom to explore diverse terrain ranging from sagebrush foothills at 2,201 feet to timbered ridges reaching 8,335 feet elevation.

The unit's recent harvest data reveals a hunting area that consistently produces elk for dedicated hunters. Over the past five years, success rates have ranged from 33% to 51%, with hunter numbers typically exceeding 200 annually. This combination of accessible terrain, abundant public land, and reliable elk populations makes Unit 40 an attractive option for hunters seeking a realistic chance at filling their tag without the extreme competition found in premier limited-entry units.

HuntPilot Analysis

Unit 40 earns a solid recommendation for hunters prioritizing opportunity over trophy potential. The harvest statistics from HuntPilot data demonstrate consistent performance: 2024 saw 220 hunters achieve a 40% success rate with 89 elk harvested, while 2023 produced similar results with 221 hunters and a 35% success rate. These numbers indicate a stable elk population that can support regular hunting pressure.

The unit's 80% public land percentage creates genuine DIY hunting opportunities without the access complications that plague many Idaho elk units. Hunters won't spend valuable time negotiating private land permissions or competing for limited walk-in access. The absence of wilderness areas eliminates guide requirements and seasonal access restrictions that can complicate hunt planning.

However, hunters should adjust trophy expectations accordingly. Counties overlapping this unit have a limited history of trophy records, indicating that while elk are present and harvestable, mature bulls reaching record-book status are uncommon. This unit excels at providing meat hunting opportunities and experience for hunters building skills, rather than producing wall-hanging trophies.

The notable jump in 2021 success rates to 51% with only 59 hunters suggests that when hunter pressure decreases, elk become more accessible and success rates improve significantly. This pattern reinforces that Unit 40 can produce good hunting when conditions align favorably.

Harvest Success Rates

Recent harvest data reveals Unit 40 as a consistently productive elk hunting destination. The 2024 season generated a 40% success rate as 89 of 220 hunters filled their tags. This represents the highest success rate in the five-year dataset and demonstrates the unit's ability to produce elk during favorable conditions.

The 2023 and 2022 seasons showed similar performance levels, with success rates of 35% and 34% respectively. These consistent mid-30% success rates indicate a stable elk population that hunters can reasonably expect to encounter with proper effort and strategy. Hunter numbers remained steady during these years, with 221 hunters in 2023 and 226 in 2022, suggesting the unit maintains its appeal among Idaho elk hunters.

The 2025 preliminary data shows 207 hunters achieving a 33% success rate with 69 elk harvested. While slightly below the previous year, this still represents a solid one-in-three chance of success for hunters willing to invest the necessary time and effort.

The most notable data point comes from 2021, when only 59 hunters participated but achieved an exceptional 51% success rate. This dramatic improvement suggests that reduced hunting pressure significantly increases individual hunter success rates. The lower hunter numbers likely resulted from pandemic-related restrictions or access limitations, creating an unusually favorable hunting environment for those who did participate.

These harvest trends indicate that Unit 40 functions best when hunter pressure remains moderate. The unit can clearly support successful elk hunting, but success rates appear inversely related to hunter density.

Trophy Quality

Trophy data for Unit 40 indicates limited potential for record-book elk. Counties overlapping this unit have a limited history of trophy records, suggesting that while the area supports a healthy elk population, it rarely produces the mature bulls that reach trophy status.

Hunters should approach Unit 40 with realistic expectations focused on harvest opportunity rather than exceptional antler size. The unit's strength lies in providing consistent chances at elk rather than producing wall-hanging specimens. This makes Unit 40 an excellent choice for hunters prioritizing meat in the freezer, gaining experience with elk behavior, or introducing new hunters to elk hunting without the pressure of once-in-a-lifetime trophy expectations.

The accessible terrain and abundant public land allow hunters to cover significant ground in search of elk, but the trophy potential remains modest based on historical records. Hunters seeking exceptional trophy potential should consider investing in more competitive limited-entry units with stronger track records of producing mature bulls.

Access & Terrain

Unit 40's 80% public land composition creates exceptional access opportunities for DIY hunters. This high percentage of public land means hunters can explore the vast majority of the unit's 1.5 million acres without permission requirements or access fees. The absence of wilderness areas eliminates guide requirements and seasonal restrictions that complicate hunting plans in other Idaho elk units.

The unit's elevation range from 2,201 to 8,335 feet provides diverse habitat types that support elk throughout different seasons and conditions. Lower elevations typically feature sagebrush country and rolling foothills, while higher elevations offer timbered terrain where elk commonly seek security cover. This elevation diversity allows hunters to adapt their strategies based on weather conditions, hunting pressure, and elk movement patterns.

The substantial acreage ensures that hunters can find areas with reduced pressure by investing effort in accessing more remote locations. With nearly 1.5 million acres to explore, dedicated hunters willing to venture beyond road-accessible areas can discover hunting opportunities away from concentrations of other hunters.

The terrain's accessibility without wilderness restrictions means hunters can utilize motorized vehicles, ATVs where legal, and other equipment to efficiently cover ground and transport harvested elk. This practical advantage reduces the physical demands of elk hunting while maintaining access to quality habitat.

How to Apply

For 2026, Idaho elk applications open May 1 with a deadline of June 5. Hunters must submit applications within this five-week window to be eligible for Unit 40 elk tags.

Nonresident hunters face application fees of $18 plus a $652 tag fee if drawn. Additionally, nonresidents must purchase a $185.00 license before applying, making the total investment $855 for a successful draw. Resident hunters pay considerably less with a $6 application fee, $37 tag fee, and required $14.75 license, totaling $57.75 for residents who draw tags.

All hunters must hold the appropriate hunting license before submitting applications. This license requirement is in addition to application and tag fees, and hunters who fail to obtain the license before applying will have their applications rejected.

Idaho operates a preference point system where hunters accumulate points for each year they apply unsuccessfully. These points improve draw probability in subsequent years, though specific point requirements vary annually based on applicant pools and tag quotas.

Dates and fees are subject to change. Always verify current application details at the Idaho Fish and Game website before applying.
