Where to See Bighorn Sheep in Wyoming

Bighorn sheep in Wyoming are found in a handful of mountain ranges. The primary populations live in the Bighorn Mountains, especially the high peaks and rugged canyons on the eastern and western slopes. You will also find them in the Wind River Range, where the terrain is steep and rocky. The mountains around Yellowstone and Grand Teton have smaller numbers. The Absaroka Range and the northern ranges of the Beartooth Mountains may have occasional sightings as well. Most of these areas share the same feature: high elevation, rocky terrain, and limited human development. If you are looking for bighorn sheep, head to these named ranges rather than lower elevation foothills.

May, June, and July are the peak months for spotting bighorn sheep in Wyoming. During these spring and early summer months, sheep move to higher elevations for better forage and water, and they become more visible. Observations from iNaturalist confirm that June has the highest sighting frequency in Wyoming. By August, sheep start moving to different elevations, and sightings drop off. Winter, from December through February, is still an active time with consistent sightings, but snow and harsh conditions make field access difficult. If you plan a bighorn sheep trip, aim for late May or June when weather is milder and sheep are most likely to be out where you can see them.

The Bighorn Mountains span the Wyoming-Montana border and hold Wyoming's most reliable bighorn sheep population. Focus on the high, rocky sections above 9,000 feet where steep cliff faces and rocky outcrops provide escape terrain. Canyon bottoms and high alpine basins between peaks are common spots. Look along the western slope above the Bighorn Basin and the eastern slope facing Montana. The areas around Cloud Peak, the highest summit in the range, have had documented sightings. Access the Bighorn Mountains via trails from the Cloud Peak Wilderness or through public lands managed by the US Forest Service. Plan for a full day hike into high elevation to maximize your odds.

Yellowstone and Grand Teton both have bighorn sheep, but viewing is not guaranteed. In Yellowstone, sheep are present in the northern range and in some high backcountry areas, but they are scattered and sightings are uncommon compared to elk or bison. Grand Teton has a small population in the high peaks and remote alpine terrain, also not easy to spot. If you visit these parks specifically for bighorn sheep, ask at visitor centers for recent sighting reports and check with backcountry rangers who have current location data. The parks are worth visiting for many other reasons, but do not expect straightforward bighorn sheep viewing like you might for bears or moose in other parks.

Yes, several outfitters offer backcountry hikes and guided trips in the Bighorn Mountains and Wind River Range with the goal of spotting bighorn sheep. These are typically multi-day backpacking expeditions or horseback trips into high alpine terrain. Guides know where sheep have been sighted and can navigate you to the right habitat during peak season. Outfitters based in Sheridan, Cody, and Jackson often offer such trips. Because bighorn sheep require steep, rocky terrain and often avoid people, even guided trips cannot guarantee a sighting. Book with an outfitter that has recent success and asks for references from past clients who saw sheep.

Bighorn sheep in Wyoming live almost exclusively in rugged, rocky mountain terrain above 8,500 feet elevation. They need steep cliffs and rocky outcrops for escape terrain when threatened. They also need nearby grass and shrub areas for forage and reliable water sources. Bighorn sheep avoid gentle slopes and forested areas. They are most comfortable on slopes steeper than 40 degrees where rock formations dominate the landscape. This habitat preference is why sightings are clustered in the Bighorn Mountains and Wind River Range rather than spread across the state. If you hike to high, craggy peaks in May or June and spot rocky benches and alpine meadows, you are in the right kind of country.

While searching for bighorn sheep in high Wyoming mountains, you are likely to encounter other alpine and subalpine species. Mule deer are common at middle and high elevations. Mountain goats live in some of the same steep terrain, particularly in the northern ranges. Elk are abundant in mountain areas, especially the Bighorn Mountains. Smaller mammals like pikas, ground squirrels, and marmots are common above tree line. You may see golden eagles soaring above high peaks. Grizzly bears are present in the Greater Yellowstone Ecosystem but are rare in lower sections of popular hikes. Bighorn sheep are the hardest to find on this list, so if you are not successful in spotting sheep, the trip will still offer good wildlife viewing.

Prepare for a serious backcountry hike into high altitude mountain terrain. Bring detailed topographic maps and a GPS device because cell service is nonexistent. Start at a trailhead with an elevation gain of at least 2,500 feet to 3,000 feet to reach the high rocky terrain where sheep live. Plan for a full day hike or a multi-day backpacking trip for better odds. Bring plenty of water, high-energy food, and a warm layer because weather at high elevation changes fast. Start early in the morning before clouds build. Bring binoculars and a spotting scope if you own one to scan rocky slopes from a distance. Move slowly and quietly, and stop often to glass the terrain with your eyes. Sheep are alert and will flee quickly if they hear or see movement.

iNaturalist has logged 1,362 verified observations of bighorn sheep in Wyoming. This represents documented sightings by citizen scientists and researchers over many years. The data shows that June is the month with the most observations, followed by May and July. This aligns with peak season for bighorn sheep visibility in the state. The relatively moderate total count across many years reflects the fact that bighorn sheep are not abundant in Wyoming compared to other western states. These observations come from hikers, biologists, and naturalists who ventured into remote high-elevation terrain. If you are planning a trip, use iNaturalist to search recent sightings in specific areas like the Bighorn Mountains to see where sheep have been spotted recently.
