In short

A high-elevation, mostly timbered OTC unit with more far-from-road ground than most units. Most of Unit 25 sits between 8,000 and 11,000 feet, with more conifer than anything else and shrubland next. Just over four-fifths of the unit is huntable public land, about a fifth of it over 90 minutes' walk from a road. CPW's survey counted 1,721 hunters across all seasons in 2024, while second rifle success fell from 15% to 11%. Archery sells over-the-counter either-sex licenses to residents only; second and third rifle sell over-the-counter bull licenses; the other seasons are draw only.

Licenses and draw

Second rifle in Unit 25, 2026: an over-the-counter bull license (E-M-000-U2-R) and a draw cow license (E-F-025-O2-R).

Access

Unit 25 has 6 trailheads and about 37 miles of road any vehicle may drive on the second rifle opener, plus 38 more that need high clearance. About a third of the huntable public ground is within a 30-minute walk of a drivable road, and about a fifth is more than an hour and a half away.

Hunt codes from the CPW 2026 big game brochure. A code valid in several units counts every hunter in all of them.

Draw results are CPW's primary-draw recap and drawn-out-at reports, 2024–2026, adult licenses. "Drawn out at" is the lowest preference-point level that drew a license; "Leftover" means licenses remained after the draw. A code valid in several units counts every applicant for all of them.

What the research says for this season

Findings from published studies and agency work, as tendencies. They describe how elk have behaved where they were studied, not where they are in Unit 25.

  • In Montana GPS work, rifle-season elk tended to hold about a mile or more from open motorized routes, in blocks of 5,000 acres or more.

    Ranglack et al., 2017 Established finding

  • At Oregon's Starkey Experimental Forest, bulls chose more canopy and kept away from open roads by day during hunts, and the shift was stronger in rifle seasons than in archery.

The numbers

CPW harvest estimates 2022–2024 for the chosen season and all seasons, the White River herd (E-6) estimate for 2025 and hunter density, 2024.

Second rifle success fell from 15% to 11% between 2022 and 2024, while the season's hunters held about steady. Across all seasons, hunters held about steady between 2022 and 2024. Unit 25 is one of 12 units in CPW's White River herd unit (E-6), estimated at about 42,000 elk after the 2025 hunt, with 19 bulls per 100 cows.

What this page can't tell you

Closures, private ground, this year's pressure and animal locations.
  • Closures. Forest, fire and road closure orders change through the season and aren't checked here. The managing agency's current order governs.
  • Private ground. Land with no public hunting access is hunted only with the owner's permission, and the public-land share above leaves it out.
  • This year's pressure. CPW's hunter numbers run a year or more behind the season you're planning.
  • Animal locations. These are terrain, access, harvest and herd figures, and CPW's mapped ranges are range lines; none of them places an animal. Finding elk is still your job.
