Wyoming Unit 21 Elk Hunting Guide

Wyoming Unit 21 spans 641,184 acres of elk country, with 76% of the unit in public ownership — making it a legitimate option for hunters who want to do their own scouting and hunting without leasing private ground. Elevations in the unit run from 6,240 feet up to 10,989 feet, offering everything from lower sagebrush benches and foothill timber to high alpine basins near timberline. For hunters comparing Wyoming elk units, Unit 21 stands out for consistent harvest numbers and a meaningful mix of public access across a large footprint.

This is a unit that shows up regularly in nonresident planning threads and Wyoming resident draw strategy discussions alike, and for good reason — it produces elk every year in solid numbers. Whether Unit 21 belongs on a hunter's short list depends heavily on residency, tag type, and what a hunter is looking for out of the hunt. Below, we break down the harvest data, tag structure, terrain, and application details using figures compiled by HuntPilot.

HuntPilot Analysis: Is Unit 21 Worth Applying For?

The harvest numbers for Unit 21 are the strongest argument in its favor. Over the last four seasons, hunter success has ranged from 35% to 43%, with 2025 posting the best mark of the stretch at 43% (1,400 elk harvested out of 3,273 hunters). That follows two seasons at 35% (2024 and 2023) and a 40% success rate in 2022. Across all four years, success has never dropped below 35% — a consistent, above-average clip for elk hunting anywhere in the West, and it signals that this is a unit where hunters who put in the effort have a genuine shot at filling a tag.

Hunter participation has also stayed high and stable, ranging from roughly 3,200 to 3,670 hunters afield per year, which tells us this unit sees consistent pressure but hasn't seen a dramatic spike or collapse in interest. That's a good sign for hunters worried about a unit getting "discovered" and overrun — Unit 21 has quietly produced solid numbers year after year without wild swings.

On the tag-quota side, Type 7 tags have grown notably, from 25 tags in 2024 to 75 in 2025 and 100 in 2026 — a 33% increase in tags from 2025 to 2026 alone. That expansion suggests the state is comfortable allocating more opportunity in this hunt type, which is worth watching for hunters building a long-term strategy around this unit. Type 6 tags, by contrast, have held flat at 200 across 2024, 2025, and 2026 — a stable, predictable allocation that isn't expanding but also isn't shrinking.

The bull:cow ratio, averaged across four survey years (2021-2024), sits at 31:100. That's on the lower end for elk herds generally, and it suggests bull numbers relative to cows are modest rather than abundant. This doesn't mean bulls aren't present — the harvest success rates confirm elk are being killed consistently — but it does mean hunters shouldn't expect to see bulls behind every cow group. It reinforces that Unit 21 is a good opportunity unit more than a place where hunters should expect to be picky about which bull they take.

Trophy potential here is best described as moderate. The counties overlapping Unit 21 carry a moderate trophy history, meaning trophy-class bulls have come from this general area, but it isn't a unit with a deep or heavy trophy pedigree. Hunters chasing a genuine trophy-caliber bull should treat Unit 21 as a solid opportunity unit with occasional trophy potential, not a unit built around consistently producing big bulls.

Bottom line: For hunters — resident or nonresident — who prioritize a good chance of harvesting an elk, solid public land access, and a large amount of huntable country, Unit 21 is worth serious consideration. For hunters chasing primarily trophy-class bulls above all else, temper expectations accordingly, though it's not out of the question given the moderate trophy history.

Herd Health & Population Trends

The available survey data covers four years (2021-2024) and shows an average bull:cow ratio of 31:100. This is a modest ratio compared to many elk herds in the West, and it's consistent across the survey period rather than showing wild year-to-year swings, which lends it credibility as a real trend rather than a survey artifact. A lower bull:cow ratio generally correlates with more pressure on bulls relative to the cow population, which lines up with the strong harvest numbers documented above — hunters are finding and killing bulls in this unit, and the ratio reflects that removal pressure.

For hunters, the practical takeaway is that Unit 21 supports a healthy number of elk overall (evidenced by consistent harvest volume in the 1,100-1,500 elk per year range), but the bull segment of that population isn't overloaded. This is a unit where persistence and mobility matter more than waiting out a specific giant bull.

Harvest Success Rates

Unit 21's harvest data over the past four years paints a picture of a dependable, productive elk unit:

• 2025: 3,273 hunters, 1,400 harvested, 43% success
• 2024: 3,458 hunters, 1,223 harvested, 35% success
• 2023: 3,222 hunters, 1,130 harvested, 35% success
• 2022: 3,670 hunters, 1,477 harvested, 40% success

These are unit-wide totals combining all hunt types and tag classes, but the trend is clear: success has stayed in a tight, favorable band, never dipping below 35% in any of the last four years, and trending upward into the 2025 season. For context, many Western elk units struggle to break 20-25% success in a given year, so Unit 21's numbers place it well above average for the region. Hunters willing to put in the physical effort across this unit's terrain have a real, data-backed chance of tagging out.

Trophy Quality

Trophy data for the counties overlapping Unit 21 indicates a moderate history of trophy-class production. This means the area has produced record-book-caliber bulls over time, but it isn't among the handful of units known for consistently churning out elite-class animals. Hunters should view Unit 21 as a unit where a mature, respectable bull is a realistic goal, and where a genuine trophy-class bull is possible but not the norm. Given the moderate bull:cow ratio discussed above, most hunters should plan around the strong odds of tagging a solid bull rather than holding out exclusively for a wall-hanger.

It's also worth noting that trophy-record entries are logged by county rather than by specific hunt unit, so the moderate trophy history associated with Unit 21's overlapping counties is shared with neighboring units in the same county boundaries — the presence of trophy-class bulls in the records doesn't mean they all came from within Unit 21 specifically.

Access & Terrain

With 76% of Unit 21 in public ownership, this is a unit where DIY hunters can realistically plan a hunt without needing to lease or negotiate private land access. The remaining 24% is private, so hunters should still expect some checkerboard ownership patterns in places, particularly at lower elevations, but the majority of the unit is open to public hunting.

Wilderness acreage in Unit 21 is minimal, at just 3% of the total unit. This is an important detail for nonresident hunters: Wyoming state law requires nonresidents to hire a licensed Wyoming outfitter when hunting in designated wilderness areas, but with only 3% of Unit 21 falling into that category, this requirement will affect only a small sliver of the unit's terrain. The vast majority of Unit 21 can be hunted by nonresident DIY hunters without an outfitter requirement.

Elevation in the unit ranges from 6,240 feet up to nearly 11,000 feet (10,989 feet at the highest points), giving hunters a genuine range of terrain types to work with. Lower elevations tend toward sagebrush flats and foothill country, while the upper reaches climb into subalpine and alpine terrain near timberline. This spread means hunters can adjust their strategy seasonally — working lower benches and edge habitat early, then following elk upward or into higher basins as conditions dictate. The scale of the unit (641,184 acres) also means there's plenty of room to get away from other hunters and find pockets of undisturbed elk, even during heavier-pressure periods.

How to Apply

For the 2026 application cycle, Wyoming elk applications open January 2, 2026. Deadlines and fees vary by residency and tag type:

Resident hunters:

• Antlerless tag: $5 application fee, $43 tag fee, deadline June 1, 2026
• Regular tag: $5 application fee, $57 tag fee, deadline June 1, 2026

Nonresident hunters:

• Antlerless tag: $15 application fee, $288 tag fee, $52 point fee, deadline February 2, 2026 (point-only deadline November 2, 2026)
• Regular tag: $15 application fee, $692 tag fee, $52 point fee, deadline February 2, 2026 (point-only deadline November 2, 2026)
• Special tag: $15 application fee, $1,950 tag fee, $52 point fee, deadline February 2, 2026 (point-only deadline November 2, 2026)

Looking further ahead, the 2028 application cycle opens January 5, 2028, with a deadline of March 1, 2028, for all regular applications.

Nonresident hunters should note that tag fees vary substantially by tag type — from $288 for an antlerless tag up to $1,950 for a special tag — so budgeting for the correct category matters when planning an application strategy. Wyoming nonresidents accumulate preference points toward future draws when they don't draw a tag, and points are consumed upon a successful draw, resetting the hunter's point total for future applications.

Dates and fees are subject to change. Always verify current application details at the state wildlife agency website before applying, or check HuntPilot's Wyoming state page (/states/wy) for the latest application calendar.

Frequently Asked Questions

What is the terrain like in Wyoming Unit 21? Unit 21 covers 641,184 acres with elevations ranging from 6,240 feet to 10,989 feet, offering a mix of lower sagebrush and foothill terrain along with higher alpine basins near timberline. With 76% public land and only 3% wilderness, most of the unit is accessible to DIY hunters without special guide requirements, though hunters should expect significant elevation gain and rugged high-country terrain in the upper reaches of the unit.

What is harvest success like in Unit 21? Harvest success has been strong and consistent, ranging from 35% to 43% over the last four seasons (2022-2025). The 2025 season posted the highest success rate at 43%, with 1,400 elk harvested among 3,273 hunters. This places Unit 21 well above the success rates typical of many Western elk units.

How big are the elk in Unit 21? Trophy data indicates a moderate history of trophy-class bulls coming from the counties overlapping Unit 21. This isn't a unit known for producing elite, record-class bulls with regularity, but respectable, mature bulls are a realistic goal, and trophy-class animals do occur. The unit's bull:cow ratio (averaging 31:100 across recent surveys) suggests hunters should focus on solid, huntable bulls rather than holding out exclusively for a trophy-class animal.

Is Unit 21 worth applying for? Based on the available data, yes — particularly for hunters prioritizing a strong chance at harvesting an elk. Four consecutive years of 35%+ success, a large public land base (76%), and growing tag allocations in some hunt types (Type 7 tags grew from 25 to 100 between 2024 and 2026) all point to a unit that rewards hunters who apply and put in the effort. Hunters focused primarily on trophy quality should weigh the moderate trophy history against those strong opportunity numbers.

Do nonresidents need an outfitter to hunt Unit 21? Only within the unit's wilderness areas, which make up just 3% of
