Boulder County for Hunters
Plan a hunt in Boulder County: which game management units it holds, where elk point rules and CWD testing apply, duck and goose areas, public ground in and near the county, and who to call at CPW.

Boulder County and its CPW area team
Wildlife staff for Boulder County report to the CPW Northeast Region, which looks after the Front Range from Fort Collins to Denver, the South Platte valley, the northeastern plains and the high parks of the Continental Divide around North Park and South Park. Day-to-day wildlife work falls to CPW Area 2, run from the Fort Collins Office in Fort Collins under area wildlife manager Jason Duetsch. The 2024 population estimate stands at 330,262 (0.2% down on the 2020 base of 330,770), and Boulder is where county government meets.
By the Census measure the county covers 726 square miles of dry ground. All of its neighbours are Colorado counties: Broomfield County, Gilpin County, Grand County, Jefferson County, Larimer County and Weld County. The Denver Office in Denver is the shortest trip, near 30 miles as the crow flies.
Population from the Census Vintage 2024 estimates; area from the 2024 Census gazetteer; neighbours from Census county adjacency; seat from the list of Colorado counties; CPW region, area and offices from the CPWAdminData layers and the CPW Contact Us page. Checked November 5, 2026.

Boulder County units, point rules and CWD
Seasons here follow 3 game management units, not the county line; GMU 20 is the biggest piece at near 51%. None of these units lies wholly inside Boulder County; each one carries on into a neighbouring county. Unit edges are roads, drainages and divides named in the brochure text; the percentages here are GIS measures, and the written description decides where a unit stops.
| Unit | County % | GMU % | Crosses into | Antler rule | Elk testing | Lion group | Spring birds | Fall birds |
|---|---|---|---|---|---|---|---|---|
| GMU 20 | 51% | 31% | Larimer, Weld | No | Yes | Group 4 | OTC | OTC |
| GMU 29 | 49% | 82% | Broomfield, Weld, Jefferson + | No | No | Group 4 | OTC | OTC |
| GMU 38 | under 1% | 1% | Jefferson, Gilpin, Clear Creek + | Yes | No | Group 4 | OTC | OTC |
CPW lists GMU 38 as antler point restriction units; count four points or measure the brow tine before shooting. CWD sampling is compulsory for chosen rifle elk codes in GMU 20, and voluntary for deer. Mountain lion hunting runs November 23, 2026 to March 31, 2027 in harvest-limit groups; the county touches group 4 (limit 28), and each group closes when its limit is reached. Leave sheds on public ground west of I-25 until May 1. OTC spring gobbler hunting is open in GMUs 20, 29, 38.

Boulder County openers and closers
Most deer, moose, sheep and goat licenses and many elk, pronghorn and bear licenses are drawn in April, so a row marked limited needs a license from the draw or the leftover list.

Buying a license for Boulder County
For resident archers, GMU 38 is open to elk on the unlimited either-sex license. Nonresident archers need a limited license from the draw for elk in Boulder County, because west of I-25 OTC archery elk is for residents only. Second and third rifle bulls in GMU 38 need only an OTC license.
| Species | OTC rows here | Limited hunt codes | PLO hunt codes | RFW hunt codes |
|---|---|---|---|---|
| Elk | 4 | 39 | 3 | 0 |
| Deer | 0 | 28 | 6 | 0 |
| Black bear | 0 | 4 | 1 | 0 |
| Moose | 0 | 14 | 0 | 0 |
| Wild turkey | 2 | 0 | 0 | 0 |
Some 99 distinct hunt codes reach these units in the 2026 big game and turkey tables. Preference points rise by one for each unsuccessful first choice; moose, sheep and goat switch to weighted points after three.
| License | In-state | Out-of-state |
|---|---|---|
| Elk, adult | $70.40 | $845.16 |
| Deer, adult | $51.25 | $506.92 |

| Mountain lion | $64.02 | $845.16 |
| Small game, annual | $38.49 | $104.86 |
Fluorescent pink counts the same as orange; camouflage patterns in those colours do not. Expect the $12.76 Habitat Stamp on top of the license price for adults under 65.

Boulder County acres by owner
The overlay finds about 141,910 public acres here, or 30.5% of the land area; the top category is forest Service land. Do not assume State Land Board land is open: only the CPW-leased parcels are. Acres with a star are left out of the public figure; hunting there depends on park, base or lease rules. Acreages come from overlaying map polygons and will not match agency totals exactly.

2024 harvest for Boulder County GMUs
There is no county harvest table in Colorado. The figures below are 2024 GMU totals from the CPW harvest surveys for the units reaching Boulder County. Elk harvest peaked in GMU 20: about 355 in 2024, with 41% of hunters filling a tag. Among these units, GMU 20 produced the most deer in 2024, an estimated 811. Bears: GMU 20 with 10 in 2024. Totals combine archery, muzzleloader and rifle, plus private-land and Ranching for Wildlife licenses.

Boulder County bird seasons and sheep units
For ducks, Boulder County is entirely Central Flyway Mountain/Foothills Zone country. Boulder County is outside the North Park, San Luis Valley and South Park goose areas, so the general Central Flyway dark goose season applies. Doves run on one statewide season, September 1 to November 29, 2026. Before a duck hunt: small game license, free HIP registration, the $12.76 Colorado stamp and the $33.00 federal stamp (16+).

| Ducks and coots | Mountain/Foothills | Oct 3–Nov 29, 2026 Dec 25–Jan 31 (2026-27) |
