Idaho hunting unit · 900 sq mi
General season — resident tags over the counter

What hunting Unit 25 is like
Unit 25 covers 900 square miles of mixed country, with substantial steep ground, running from valley bottoms around 3,300 feet up to peaks near 9,300 feet, with most of the hunting happening around 6,700 feet. Slopes average a bit over 22 degrees, and the terrain breaks down to roughly two-fifths moderate, a similar share steep, and only a small sliver rugged — enough broken ground that legs and lungs matter, but not a unit defined by cliff bands. Cover shifts with elevation: sagebrush dominates at every band, timber is a strong secondary presence throughout, and grass and meadow openings become more common the higher a hunter climbs. A small slice of the unit falls inside the Frank Church - River of No Return Wilderness, where no motorized travel is allowed and foot or stock access is the rule.
Almost all of Unit 25, about 99 percent, sits on Boise National Forest, Payette National Forest, and Salmon-Challis National Forest ground along with Idaho state endowment land, and that land is generally open to public hunting — though state parcels can occasionally be posted closed or leased, so nothing is absolutely guaranteed. Two recent fires have reshaped parts of the habitat: the Buck fire burned around 19,000 acres on the unit's east side, and the Snag fire burned about 15,000 acres on the southwest side. Both are worth building into a plan, since burned ground hunts very differently depending on how many seasons have passed since the flames. Hunters should check for current fire closures before heading out.
Tag choice in Unit 25 comes down to which deer a hunter wants and which weapon season fits. Residents buy general regular deer or white-tailed deer tags over the counter with no draw required, while nonresidents apply for one specific tag — regular or white-tailed — through a random draw at the time of application, not after. A single controlled hunt adds a rut-season option for hunters willing to take on very long odds in the draw.
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.
| Season | Dates | Legal deer | Rut phase |
|---|---|---|---|
| Regular deer tag · Archery | August 30 – September 30 | Antlered or antlerless | Summer Range / Bachelor Pattern, Velvet Shed / Early Fall Transition |
| White-tailed deer tag · Archery | August 30 – September 30 | Antlered or antlerless | Summer Range / Bachelor Pattern, Velvet Shed / Early Fall Transition |
| Regular deer tag · Any weapon | October 10 – October 31 | Antlered; antlerless: youth only | Early Fall Migration / Nocturnal Buck Phase, Early Pre-Rut / Migration Corridor Staging |
| White-tailed deer tag · Any weapon | October 10 – October 31 | Antlered or antlerless | Early Fall Migration / Nocturnal Buck Phase, Early Pre-Rut / Migration Corridor Staging |
Regular deer tag · Archery · August 30 – September 30
Late August into September finds bucks still in velvet and loosely bachelored on their summer range, feeding on forbs and browse and needing very little water to get by. The best plan is to glass at first light from vantage points overlooking shady pockets and north-facing slopes, mark where a buck beds, then close the distance in the middle of the day while he's down. Evening glassing often just confirms a bed for a return trip the next morning rather than setting up an immediate stalk. This tag allows an antlered or antlerless regular deer — mule deer or white-tailed deer — taken by archery equipment only.
White-tailed deer tag · Archery · August 30 – September 30
The same velvet-to-shed transition plays out through this stretch, with bucks bachelored up and holding tight to summer range before easing into more solitary, shade-bound patterns as September wears on. Glass early to locate a buck, watch him bed, then work the stalk at midday; evenings are often better spent confirming a bedding area than pushing a shot. A buck that vanishes from view is usually still nearby in a crevice or draw rather than gone for good. This archery season is limited to white-tailed deer, antlered or antlerless.
Regular deer tag · Any weapon · October 10 – October 31
By October, bucks that were visible all summer turn increasingly nocturnal, and most haven't left their summer ground yet, so still-hunting the fringes of known bedding cover and glassing at the edges of daylight pays off. Late in the month some deer start drifting toward rutting range, which makes the country between summer haunts and rut staging areas worth extra glassing time. The regular deer tag allows an antlered mule deer or white-tailed deer under any weapon, with an antlerless deer legal only for a youth hunter.
White-tailed deer tag · Any weapon · October 10 – October 31
October brings the same shift toward nocturnal behavior seen across the unit, with white-tailed bucks holding near summer range early and starting to stage toward rut country as the month closes. Working the transition zones between bedding cover and open feed at dawn and dusk, and glassing the corridors deer use to move toward rutting ground late in the month, are the most productive tactics. This any-weapon season allows an antlered or antlerless white-tailed deer, giving more flexibility than the regular tag's October season.
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 25 is valid only in its own hunt area.
| Season | Dates | Legal deer | Resident draw | Rut phase |
|---|---|---|---|---|
| Controlled hunt 25 · Any weapon | October 10 – November 24 | Antlered only | Very long odds | Early Fall Migration / Nocturnal Buck Phase, Early Pre-Rut / Migration Corridor Staging, Primary Rut |
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 25 · Any weapon · October 10 – November 24
This long controlled hunt opens during the same nocturnal, staging-phase behavior seen in October, then carries into the primary rut in November when bucks are actively seeking does. Incoming weather in November can push deer down out of the high country onto ground that's easier to glass and reach, and a fresh skiff of snow is a good time to cut buck tracks. The smartest approach is to find concentrations of does, since rutting bucks won't be far off; only antlered bucks are legal, and residents drawing Controlled hunt 25 should expect very long odds given the limited tags.

Unit 25 deer hunting FAQ
Can a resident buy a deer tag for Unit 25 without going through a draw?
Yes. Residents purchase general regular deer or white-tailed deer tags over the counter for Unit 25, with no application or draw involved. Those tags cover the archery season from August 30 to September 30 and the any-weapon season from October 10 to October 31, each with its own legal-animal rules.
How do nonresidents get a general deer tag in Unit 25?
Nonresidents apply for a general deer tag through a random draw, and they must choose a specific tag — either the regular deer tag or the white-tailed deer tag — at the time they apply. The tag is never chosen after the draw, so the decision on which animal to hunt has to be made up front.
How hard is it to draw the controlled hunt in Unit 25?
Controlled hunt 25, the any-weapon rut-season hunt running October 10 through November 24, carries very long odds for resident first-choice applicants. It is a pure random draw with a limited number of tags and no points system to improve the odds over time.
Which deer tags are valid in Unit 25 and what's the difference?
The regular deer tag covers either mule deer or white-tailed deer unless a specific season restricts it further, while the white-tailed deer tag is valid for white-tailed deer only. Both tags have separate archery and any-weapon seasons with their own legal-animal rules, so it pays to check which tag matches the animal and weapon a hunter wants.
How much of Unit 25 can a hunter count on for public access?
About 99 percent of the unit, roughly 895 square miles, is National Forest or Idaho state endowment land that is generally open to public hunting. State endowment parcels can occasionally be posted closed or under lease, so a hunter should treat that figure as a strong baseline rather than an absolute guarantee.
