Grouse Hunting Season in Colorado: Dates, Limits, and Permits for 2026-27
November 1, 2026
Grouse hunting season in Colorado opens September 1, which means you can be chasing dusky grouse in aspen and spruce while elk hunters are still scouting. The state offers several grouse species, but each one has its own dates, limits, and legal areas, and a few need a separate permit on top of your small game license.
This article walks you through the 2026-27 rules as published by Colorado Parks and Wildlife (CPW) and secondary sources that read from the 2026 brochure. You will find season dates, daily limits, license requirements, unit restrictions, and tips on telling legal birds from protected ones. Regulations can be corrected after publication, so treat this as a planning tool and confirm everything against the official brochure before you go.
Important Note: Sources disagree by a day or two on some end dates. Dusky grouse is listed as ending November 22 in the CPW brochure summaries, while a few sites list November 23, and sharp-tailed grouse is listed as ending September 20 or 21. Use the official CPW brochure as the final word.
Which Grouse Species You Can Hunt in Colorado
Colorado has an open season for three true grouse: dusky grouse, greater sage-grouse, and mountain sharp-tailed grouse. White-tailed ptarmigan, a grouse relative that lives above treeline, is hunted under the same $5 permit as sage-grouse and sharptails. Chukar partridge is sometimes lumped in with grouse, but it is a separate upland species with its own statewide season.
The dusky grouse (Dusquicola obscurus) is the bird most hunters pursue. These birds live between roughly 8,000 and 11,000 feet depending on the time of year, according to Divebomb Industries. Many are taken incidentally by elk and deer hunters working the same timber.
The greater sage-grouse (Centrocercus urophasianus) is a sagebrush specialist found in the northwest part of the state. Ultimate Upland notes that CPW treats the species as a conservation priority with extensive monitoring, which is why seasons are so short and limited to specific units. The mountain sharp-tailed grouse (Tympanuchus phasianellus columbianus) is also restricted to designated units and a short September window.
The ruffed grouse is not a legal option for hunters in Colorado, so you should not plan a trip around it. Related reading on other Colorado game: the turkey hunting season in Colorado overlaps with early grouse timing in some national forest country.
Grouse Hunting Season Dates in Colorado
Dates below reflect the 2026-27 season. The Colorado Hunting Guide summarizes the 2026 CPW Small Game and Waterfowl Brochure and was last verified in October 2026. Where sources conflict, the range of reported dates is shown.
| Species | 2026-27 Season | Area |
|---|---|---|
| Dusky (blue) grouse | September 1 to November 22 (some sources list November 23) | West of I-25 |
| Greater sage-grouse | September 12 to 18 (Season 1); September 12 to 13 (Season 2, North Park) | Designated GMUs only |
| Mountain sharp-tailed grouse | September 1 to 20 (some sources list September 21) | Designated GMUs only |
| White-tailed ptarmigan | September 12 to October 4, with an extended window to November 22 in select GMUs | Varies by GMU |
The ptarmigan window comes from StateOutdoors.org, and the sage-grouse and sharptail dates match the figures reported by HuntWise. Because the sage-grouse and sharptail seasons run one to two weeks, you need to plan those trips around the opening weekend.
Dusky grouse gives you the longest runway, nearly three months. Early September means warm, dry hiking and birds up high, and later in the season, snow pushes them down into mixed conifer. If you also hunt big game, check how your plans fit with the deer hunting season in Colorado and the bear hunting season in Colorado, since they share the same national forest ground.
Daily Bag and Possession Limits for Grouse in Colorado
Limits depend on the species, and the sage-grouse and sharptail limits are small. Figures below come from the 2026-27 summaries published by HuntWise and match the structure of the CPW brochure.
| Species | Daily Limit | Possession Limit |
|---|---|---|
| Dusky (blue) grouse | 3 | 9 |
| Greater sage-grouse | 2 | 4 (2 in the North Park Season 2 hunt, per the 2025 brochure) |
| Mountain sharp-tailed grouse | 2 | 4 |
| White-tailed ptarmigan | 3 | 6 (per 2025 brochure listing) |
The possession limit is the total you can hold at any time, including birds in your freezer, cooler, or vehicle. For dusky grouse, that is three days’ worth of daily limits. The ptarmigan and North Park figures above come from the 2025 brochure listings, so check the 2026 brochure for any change.
Pro Tip: Keep one grouse species per bag when you can. Mixed bags of sage-grouse, sharptail, and ptarmigan make it easy to lose track of species-specific limits, and each species is counted separately.
Licenses, Stamps, and Special Permits for Grouse in Colorado
You need a small game license for any grouse hunting in Colorado. Hunter education is required for most hunters born on or after January 1, 1949, so make sure your certification is on file with CPW.
Starting with the 2025 seasons, CPW added a requirement that is easy to miss. The CPW Small Game and Waterfowl Brochure states that an annual $5 permit is required for white-tailed ptarmigan, greater sage-grouse, and mountain sharp-tailed grouse. Dusky grouse does not need this extra permit.
Licensing details also change by residency and age, so price out the full package on the CPW site before you travel. A quick checklist keeps you covered:
- Valid Colorado small game license
- Hunter education certification, if required for your birth date
- $5 ptarmigan, sage-grouse, and sharptail permit when hunting those species
- Habitat Stamp, if it applies to your license type
Confirm the Habitat Stamp rules and current fees directly with CPW, since those amounts were not verified in the sources used for this article.
Zones, Units, and Closed Areas for Grouse in Colorado
Colorado manages grouse by Game Management Unit (GMU), and the boundaries matter more here than for almost any other small game bird. Dusky grouse is the simple one: it is open west of I-25, which covers the mountains and the Western Slope.
Sage-grouse and sharptail hunting is only legal inside listed GMUs. The 2024 CPW brochure noted that GMUs 2, 4, 5, and 10 were opened to sage-grouse hunting because the three-year population average was above threshold, and it listed Mountain sharp-tailed grouse as open only in specific units such as GMUs 4, 5, 12, 13, and 14, among others, per the CPW brochure. Those unit lists can shift each year based on population counts, so use the 2026 brochure maps.
North Park (GMUs 6, 16, 17, 161, and 171) has its own shortened sage-grouse season, which is why you see two sage-grouse date ranges in the table above. Hunting outside a listed unit is a violation even if the habitat looks identical and the season is open one valley over.
Closed areas also include places where firearms or hunting are restricted, such as many state parks and developed recreation sites. Check the unit map and the land manager’s rules for each parcel before you hike in.
Legal Weapons and Hunting Methods for Grouse in Colorado
Most grouse hunters use a shotgun, and many upland hunters carry a 20 gauge for the lighter weight over steep ground. Archery equipment is also allowed for small game, and Colorado Outdoors coverage notes that many bowhunters add a rubber-tipped arrow to the quiver to take a dusky grouse during big game archery trips.
Because dusky grouse often sit still or walk away rather than flush, some hunters in the high timber take birds on the ground or in trees. That is legal in Colorado for grouse as small game, but follow safe shot placement, especially when other hunters are in the same drainage.
Non-toxic shot rules apply on some public lands, and the CPW brochure lists the specifics. Check these points before you load up:
- Shotgun shot type required on the property you are hunting
- Any plug requirements for migratory bird hunting (not required for grouse, but relevant if you carry the same gun for doves)
- Rules on motor vehicles, which are limited to designated roads in national forests
If you pair grouse with another bird trip, the dove hunting season in Colorado article covers the migratory bird gear rules that differ from grouse.
Shooting Hours for Grouse Hunting in Colorado
Small game shooting hours in Colorado are generally one-half hour before sunrise to sunset. That rule applies to most upland birds, and the CPW brochure lists any exceptions for specific species or migratory birds. The sources gathered for this article did not publish an exact shooting-hours statement for grouse, so confirm the wording in the 2026 brochure.
In September, sunrise comes around 6:30 a.m. in the mountains, so you have a long day. By November, sunset is before 5 p.m., and you will want to be off the mountain well before dark. Plan your hike back so you are not navigating logging roads in the dark.
How to Identify Legal Grouse Versus Protected Look-Alikes in Colorado
Identification is where hunters get into trouble. Dusky grouse and sage-grouse overlap in some northwest Colorado country, and sharptails and greater prairie-chickens share open grassland in parts of the northeast. Prairie-chicken seasons are separate and, per The Colorado Hunting Guide, open October 1, so a bird that is legal in one season may be off limits in another.
Use these field marks to separate the main species:
- Dusky grouse: Dark gray to brown, forest dweller, often sits on logs or walks through berry shrubs. Males fan tail feathers during display.
- Greater sage-grouse: Large, with black belly and pointed tail, found in open sagebrush.
- Sharp-tailed grouse: Pale, spotted body with a short pointed tail and white outer tail feathers, found in grass and shrub country.
- White-tailed ptarmigan: Small, mottled brown in summer and early fall, living above treeline in alpine tundra.
Other protected birds can look similar in the field. Lesser prairie-chickens and Gunnison sage-grouse are not legal game in Colorado, so if you are hunting in a unit near their range and cannot positively identify a bird, do not shoot.
Common Mistake: Shooting a sage-grouse in a unit that is closed. A bird that looks legal can still be off limits because the GMU is not on the open list. Confirm the unit before you step out of the truck.
Where to Hunt Grouse on Public and Private Land in Colorado
Much of Colorado’s dusky grouse habitat is public. Hunting Locator reports that Colorado has 14.5 million acres of National Forest and Grasslands open to hunting, and Divebomb Industries points to national forests and BLM parcels covering large parts of the high country.
For dusky grouse, the Routt National Forest northeast of Craig traditionally accounts for a large share of the statewide harvest, with more birds taken in Routt County than anywhere else. Crested Butte is another area hunters mention for blue and sage grouse.
For sage-grouse, look to the sagebrush country near Craig and Meeker in northwest Colorado. For the ptarmigan hunt, you need to be willing to climb to alpine terrain, and the season is short.
On private land, you need landowner permission before you hunt, and you should ask early since many ranches host big game hunters in the fall. State Wildlife Areas such as Tamarack and Sandsage are better known for plains birds than grouse, so use them as a side trip rather than a grouse destination.
Conditions matter too. Ultimate Upland rated the 2026-27 outlook as fair for dusky grouse because higher elevations offer some drought protection, and fair to poor for sage-grouse. Scout early and be ready to move to wetter drainages if the bird numbers look thin. You can also compare timing with the turkey hunting season in Utah if you are planning a regional upland trip.
How to Confirm Current Grouse Regulations With Colorado’s Wildlife Agency
CPW publishes the official rules, and it is the only source that carries legal weight. The agency’s small game page lists the 2026 Small Game and Waterfowl Brochure, and its rules and regulations page links all regulation brochures in one place.
- Download the 2026 Small Game and Waterfowl Brochure from CPW and read the grouse pages, including the unit maps.
- Check that your GMU is on the open list for sage-grouse and sharptail hunting.
- Verify season end dates, since sources differ by a day on some species.
- Buy your small game license and the $5 permit before you leave, if you are hunting those species.
- Call or visit the CPW office for the area you plan to hunt for any emergency closures, fire restrictions, or access updates.
Regulations are adopted each year and can be corrected after publication, so recheck the brochure a week before your trip. If you hunt in more than one state, keep the rules separate, and compare with guides like the pheasant hunting season in Montana to avoid carrying habits from one state to another.
Colorado grouse hunting rewards the hunter who plans around units and permits. Get the paperwork right, know your bird, and you have nearly three months of high-country hunting ahead of you.
