Unit 37A Deer Hunting, Idaho
Idaho hunting unit · 349 sq mi
General season — resident tags over the counter
Residents buy general deer tags over the counter — no draw, no points. Nonresident general tags are allocated by random draw. It also has 4 controlled hunts, drawn by pure random draw with no points — resident odds from good odds to fair odds.
What hunting Unit 37A is like
Unit 37A sits in the Salmon-Challis National Forest, running from valley floor near 4,400 feet up to peaks above 11,400 feet. The terrain is mixed, with substantial steep ground — nearly two-thirds of the unit is moderate to steep, and hunting it on foot means committing to real elevation gain to reach the mid and higher country where deer spend much of the season. Lower elevations are dominated by sagebrush with pockets of conifer, mid elevations split about evenly between conifer timber and sagebrush, and the highest country returns to mostly sagebrush with substantial timber mixed in — cover that rewards careful glassing over blind still-hunting.
Public land accounts for roughly 94 percent of the unit, a mix of National Forest, BLM and Idaho state endowment ground, which gives a hunter a lot of country to work with, though that doesn't make any given piece of it easy to get into or across given the slope involved. State endowment parcels are generally open but can be posted closed or leased, so it pays to check status rather than assume. The remaining ground, around 6 percent, is private and requires written permission.
Deer tags here split by animal and by residency path. Residents buy either the regular deer tag or the white-tailed deer tag over the counter with no application; nonresidents go through a random draw for a general tag but must choose which specific tag — regular deer or white-tailed deer — at the time they apply, not afterward. On top of the general seasons, a handful of controlled hunts add archery, muzzleloader, and antlerless-only white-tailed deer opportunity, each a separate random draw with its own limited number of tags.
General-season deer (2026)
The Regular Deer tag is valid for mule deer or white-tailed deer unless a season says otherwise; the White-tailed Deer tag is white-tailed deer only. Residents buy general deer tags over the counter; nonresident general tags are allocated by random draw.

Regular deer tag · Archery · August 30 – September 30
Late summer into September finds bucks still in velvet and loosely bachelored on their summer range, spending the day bedded in shade and feeding into the morning and again in the evening. In this mixed sagebrush-and-timber country, that means glassing shady pockets and north-facing slopes at first light, marking where a buck beds, and closing the distance in the middle of the day while he's down. Evening glassing works too, though it's often more useful for pinning a buck's pattern and returning the next morning than for a same-evening stalk. This tag covers either mule deer or white-tailed deer, antlered or antlerless, with archery gear only through the end of September.
White-tailed deer tag · Archery · August 30 – September 30
The same velvet-and-bachelor pattern holds for white-tailed bucks through late summer and into September, with deer feeding heavily on forbs and browse and bedding through the heat of the day in shade or on north-facing ground. Glass at first light to locate a buck, watch him bed, then work in on him while he's down; use the evening glass to pattern him for a follow-up rather than force a stalk. Once velvet sheds, habits carry over but bucks tend to bed earlier and stay down later, so checking small crevices and draws near where one was last seen is worth the effort. This archery-only tag is valid for white-tailed deer, antlered or antlerless.
Regular deer tag · Any weapon · October 10 – October 24
By October bucks are sliding into their nocturnal phase, moving mostly under cover of darkness and staying close to the same ground they held through summer. That makes daylight movement harder to catch and rewards patience over long glassing sessions rather than covering ground. Early-season snow is possible and temperatures start dropping into the high 20s, but the bigger factor is simply that bucks are harder to catch moving. This any-weapon season is antlered only under the regular deer tag, good for mule deer or white-tailed deer.
White-tailed deer tag · Any weapon · October 10 – October 31
October opens with the same increasingly nocturnal buck pattern before shifting toward migration staging as the month closes, with deer beginning to drift from summer range toward rutting ground. Early on, hunting stays similar to any October hunt — patient glassing of known summer haunts — but by late month it pays to start watching the country between summer range and likely rut destinations. Snowfall picks up modestly and lows drop toward the high 20s. This any-weapon tag is for white-tailed deer, antlered any time, with antlerless legal only for youth, and access in parts of the unit is very limited.
White-tailed deer tag · Short-range weapons · November 1 – December 9
This season opens on the tail end of the migration-staging period and runs through the entire primary rut and into late-rut consolidation, making it the best stretch for catching bucks on their feet. Weather moving through in November and December often pushes deer down out of the high country onto lower, more glassable ground, and fresh snow is a good time to cut fresh buck tracks. Glassing early and late remains the go-to tactic, and finding does is usually the fastest way to find a rutting buck nearby. Snowfall builds through the period and lows drop into the teens and single digits, so gear and access both get tougher as the season wears on; this short-range-weapon tag is antlered white-tailed deer only, with very limited access in parts of the unit.
White-tailed deer tag · Short-range weapons · November 1 – December 31
This long season runs from migration staging through the primary rut and into late-rut consolidation, with snowfall building steadily and lows dropping from the high teens into the single digits by December. For an antlerless white-tailed deer tag, the practical approach is to work the lower, more open sagebrush ground where deer concentrate as weather pushes them down out of higher timbered country, glassing early and late in the day. Access is very limited in parts of the unit, so scouting travel routes into huntable ground matters as much as finding deer. This tag is valid only for antlerless white-tailed deer.
Controlled deer hunts (2026)
Controlled hunts have a limited number of tags and are drawn by pure random draw — Idaho uses no points, so years of applying do not improve the odds. First choices are drawn before second choices. A hunt marked as covering part of Unit 37A is valid only in its own hunt area.
| Season | Dates | Legal deer | Resident draw | Rut phase |
|---|---|---|---|---|
| Controlled hunt 21-1 · Archery Archery only; Motorized Hunting Rule Applies in Units 29 and 37A | August 1 – September 30 | See the hunt's rules | — | Summer Range / Bachelor Pattern, Velvet Shed / Early Fall Transition |
| Controlled hunt 36A-1X · Any weapon Youth only; White-tailed deer only; Motorized Hunting Rule Applies in Unit 37A | August 30 – December 31 | Antlerless only | Youth only | Summer Range / Bachelor Pattern, Velvet Shed / Early Fall Transition, Early Fall Migration / Nocturnal Buck Phase, Early Pre-Rut / Migration Corridor Staging, Primary Rut, Late Rut / Winter Consolidation |
| Controlled hunt 36A-1X · Any weapon Extra antlerless tag; White-tailed deer only; Motorized Hunting Rule Applies in Unit 37A | August 30 – October 31 | Antlerless only | Good odds | Summer Range / Bachelor Pattern, Velvet Shed / Early Fall Transition, Early Fall Migration / Nocturnal Buck Phase, Early Pre-Rut / Migration Corridor Staging |
| Controlled hunt 36A-1X · Any weapon Extra antlerless tag; White-tailed deer only; Motorized Hunting Rule Applies in Unit 37A | November 1 – December 31 | Antlerless only | Fair odds | Early Pre-Rut / Migration Corridor Staging, Primary Rut, Late Rut / Winter Consolidation |
| Controlled hunt 29-1 · Muzzleloader Muzzleloader only | November 25 – December 9 | See the hunt's rules | — | Primary Rut, Late Rut / Winter Consolidation |
Resident draw is a band in words from the 2026 first-choice results: good, fair, long or very long odds. It is not a published percentage, and nonresident odds differ. Youth-only hunts are shown without a band.
Controlled hunt 21-1 · Archery · August 1 – September 30
This controlled archery hunt spans the same velvet and early-fall-transition period as the general archery seasons, with bucks bachelored on summer range and holding a predictable daily rhythm of early feeding, daytime bedding in shade, and evening movement. Glassing at first light to spot a buck and mark his bed, then closing in during the midday bedding period, is the core tactic in this mixed sagebrush-and-timber terrain; evening glass sessions are often better used to pattern a buck for the next morning. As velvet sheds toward late September, bucks tend to bed earlier and later, so checking nearby crevices and draws for a buck that seems to vanish is worth doing. This is an archery-only draw hunt with its own tag numbers and rules.
Controlled hunt 36A-1X · Any weapon · August 30 – October 31
This antlerless-only white-tailed deer hunt runs from late summer through the end of October, spanning the period when deer are on summer range, shedding velvet, becoming more nocturnal, and beginning to stage for migration. Hunting it means working the sagebrush-and-conifer mix at lower and mid elevations where white-tailed deer concentrate, with October bringing modest snowfall and lows near the high 20s. Terrain here is mixed with a lot of steep ground, so picking accessible glassing points and working them patiently is more productive than trying to cover the whole unit on foot. This is an extra antlerless tag drawn separately from the general seasons, and resident first-choice odds run good.
Controlled hunt 36A-1X · Any weapon · November 1 – December 31
This antlerless-only white-tailed deer hunt covers November and December, spanning the tail of migration staging through the entire rut and into late-rut consolidation, with snowfall building from around 10 inches in November to over 16 inches in December and lows dropping into the teens and single digits. Deer tend to work down out of higher timbered ground onto lower, more open sagebrush terrain as weather sets in, which is where an antlerless hunter should concentrate effort. Access can be a factor as snow accumulates, so it pays to plan routes into huntable ground before conditions close them off. This is an extra antlerless tag drawn separately from the general seasons, with resident first-choice odds running fair.
Controlled hunt 29-1 · Muzzleloader · November 25 – December 9
Running from late November into December, this muzzleloader hunt falls squarely in the primary rut and late-rut consolidation, when bucks are most likely to be moving with does. Weather at this time of year regularly pushes deer down out of the high country onto lower, easier-to-glass ground, and fresh snow — common by late November — is a good time to look for fresh buck tracks. Glassing early and late and then keying on groups of does is the most reliable way to locate a buck. This is a muzzleloader-only controlled hunt with its own limited tag numbers.

Unit 37A deer hunting FAQ
Can a resident buy a deer tag for Unit 37A over the counter?
Yes. Residents can buy either the regular deer tag or the white-tailed deer tag over the counter with no application or draw required. The choice of tag determines which seasons and legal animals apply.
How do nonresidents get a general tag for this unit?
Nonresidents go through a random draw for a general tag, and they must choose the specific tag — either regular deer or white-tailed deer — at the time they apply. The tag cannot be chosen after the draw results are known.
How hard are the controlled hunts in Unit 37A to draw?
Difficulty varies by hunt. The antlerless white-tailed deer hunt running August 30 through October 31 carries good resident first-choice odds, while the same hunt running November 1 through December 31 carries fair odds; the archery-only and muzzleloader hunts are pure random draws with their own limited tag numbers.
Which deer tags work in Unit 37A?
The regular deer tag covers mule deer or white-tailed deer unless a specific season restricts it, while the white-tailed deer tag is valid for white-tailed deer only. Both tags have separate archery, any-weapon, and short-range-weapon seasons with their own dates and legal-animal rules.
How much of Unit 37A is public land a hunter can count on?
About 94 percent of the unit is generally open to public hunting, made up of National Forest, BLM, and Idaho state endowment land. That's a large share, but state endowment parcels can occasionally be posted closed or leased, and the unit's steep, mixed terrain means public access still takes real effort to use.
