Unit 12 Elk Hunting, Idaho
Idaho hunting unit · Lolo Elk Zone · 1,189 sq mi
General season — resident tags over the counter
Residents buy general elk tags over the counter — no draw, no points. General elk is sold by zone: Unit 12 is in the Lolo Elk Zone, whose A and B tags carry different seasons. Nonresident general tags are allocated by random draw. The zone's A tag and B tag are capped: a limited number, sold first-come, first-served.
What hunting Unit 12 is like
Unit 12 is big, mixed country running from low river bottoms up to nearly 8,800 feet, with 38% steep and 3% rugged ground by area alongside gentler benches and slopes. The Selway Bitterroot Wilderness covers about 31% of the unit and is closed to motorized travel, meaning a good share of the best country is reached on foot or by stock. Timber dominates the cover at every elevation, holding 88% of the low country and still 61% of the high country, with sagebrush and grass and meadow opening up more as elevation climbs, giving hunters places to glass in the upper reaches even as the lower forest stays thick.
National Forest, split between the Clearwater National Forest and the Nezperce National Forest, makes up about 95% of Unit 12 and is generally open to public hunting, while private land accounts for about 5.3% and requires written permission to access. Two fires have reshaped parts of the unit: the Storm Creek fire burned about 15,000 acres on the east side, and the Warm Springs fire burned about 5,200 acres toward the middle of the unit. The Storm Creek burn is now five to eight years old and has grown back thick with brush and deadfall, while the Warm Springs burn, two to four years out, still offers open sightlines and strong feed; hunters should check for current fire closures before heading in.
Elk in Unit 12 are hunted under the Lolo Elk Zone's general tags, which residents buy over the counter and nonresidents draw through a random draw in which they apply for a specific zone tag, either the A tag or the B tag, chosen at the time of application. Both tags are capped and sold first-come, first-served until they run out, and each carries its own season and weapon rules described below.
General-season elk (2026)
General elk tags are sold by zone. Unit 12 is in the Lolo Elk Zone (Units 10 and 12); a hunter chooses its A tag or its B tag, and each carries its own seasons. The windows below are the ones valid in Unit 12. Residents buy the tag over the counter; nonresident general tags are allocated by random draw.
| Season | Dates | Legal elk | Rut phase |
|---|---|---|---|
| A tag · Archery Valid area: Units 10 and 12 | August 30 – September 30 | Antlered only | Pre-Rut Transition, Rut Onset, Primary Rut |
| B tag · Any weapon Valid area: Units 10 and 12 | October 10 – November 3 | Antlered only | Late Rut / Early Post-Rut, Post-Rut Recovery, Migration Transition |
A tag · Archery · August 30 – September 30
Archery season opens as bulls are finishing the Pre-Rut Transition and running into Rut Onset and then Primary Rut by its final weeks, so calling and bugling activity builds through the month. Early on, bulls are still shaking off velvet and holding close to where they spent summer, making sitting water or glassing for a spot-and-stalk approach a solid tactic in the mixed timber and openings. As the rut phases progress later in September, bulls become more responsive to calling. The tag is antlered-only and archery-only, valid in Units 10 and 12, and the thick regrowth in the Storm Creek burn can hide bulls well while the more open Warm Springs burn offers better glassing and feed for animals working its edges morning and evening.
B tag · Any weapon · October 10 – November 3
By the time the any-weapon season opens, elk have moved past the rut into Late Rut and Early Post-Rut, then Post-Rut Recovery, and finally into the Migration Transition phase as the season closes in early November, so hunters can expect elk shifting toward winter patterns rather than responding to rut behavior. Snowfall builds through the season, from around an inch in October to over ten inches by November, which can push elk out of the highest country and make travel harder in the steep and rugged ground that makes up a large share of the unit. The tag is antlered-only and valid in Units 10 and 12 under any legal weapon, and the Warm Springs burn's open ground can still be worth glassing early and late in the day even as elk begin moving toward lower or more sheltered terrain.

Unit 12 elk hunting FAQ
Can a resident buy an elk tag for Unit 12 over the counter?
Yes. Residents buy the Lolo Elk Zone's general A tag or B tag over the counter with no draw or application required, as long as tags remain available since both are capped and sold first-come, first-served.
How do nonresidents get a general elk tag for Unit 12?
Nonresidents enter a random draw and must apply for a specific tag, either the Lolo Zone's A tag or its B tag, at the time they apply. The tag choice is made when applying, not after the draw, and both tags are capped in number.
Which elk zone and tags cover Unit 12?
Unit 12 falls in the Lolo Elk Zone along with Unit 10. The zone offers an A tag with an archery season and a B tag with an any-weapon season, each with its own dates and both restricted to antlered elk.
Do any of the Unit 12 elk seasons fall during the rut?
The A tag archery season, August 30 through September 30, spans the Pre-Rut Transition, Rut Onset, and Primary Rut phases, so it covers the core of the rut. The B tag any-weapon season, October 10 through November 3, falls after the rut in the Late Rut, Post-Rut Recovery, and Migration Transition phases.
How much of Unit 12 is public land a hunter can count on?
About 95% of the unit is National Forest, split between the Clearwater National Forest and the Nezperce National Forest, and is generally open to hunting. The remaining roughly 5.3% is private and requires written permission to access.
