Desert Bighorn Sheep in Zion National Park: Where to Look on the East Side

Most people come to Zion for the canyon walls. A surprising number leave talking about the sheep. Desert bighorn sheep live on the park's steep east side, and on a good day you'll spot one standing on a sandstone ledge that looks far too narrow for anything with hooves. They're also a real comeback story: gone from the park by the mid-1900s, they now number in the hundreds (NPS).

Zion's bighorn stick to steep, rocky country: cliffs, peaks, and shady gullies where they can climb away from trouble. You can see them any time of year, and fall is a good time to look, since the rut runs into October. Even so, they're wild animals on a big landscape, and no drive comes with a guaranteed sighting.

How to Recognize a Desert Bighorn

Zion's sheep are the desert subspecies, Ovis canadensis nelsoni. Next to their Rocky Mountain cousins they're smaller-bodied and longer-legged, with shorter coats built for heat (NPS). The coat is brown, often quite pale on desert sheep, with white fur on the muzzle, rump, and belly (NPS).

The horns tell you who's who. Rams carry the big, heavy horns that curl back and around; a large ram can weigh up to about 250 pounds. Ewes have short horns with only a slight curve (NPS). The animal in the main image, with its short, gently curved horns, fits the ewe pattern; the ram below shows the difference.

The likeliest mix-up in Zion is a mule deer. Deer are taller and slimmer, have big ears, and have no horns at all (bucks grow antlers that branch and drop off each year). A bighorn looks stockier and moves across rock like it was poured there.

Where and When to Look in Zion

The park is specific about this: your best chance is on the east side, between the Zion-Mount Carmel Tunnel and the East Entrance. Look for sheep crossing the road, standing on a peak, or resting in shaded gullies (NPS). Scan the ledges and skylines as well as the roadside.

They're around all year. A passenger who can scan the cliffs while the driver drives is worth a lot here. If you see one, don't stop in the road; keep going to the next pullout.

What They're Doing This Time of Year

The rut runs from July through October. That's when rams square off and crash their horns together, and the winner earns mating access to the ewes in the herd (NPS). Lambs arrive about six months later; newborns show up from mid-January through the end of April (NPS).

Two things worth knowing. First, they're built for this rock. Their flexible hooves have soft, spongy pads that grip sandstone, and they can go days without drinking in summer (St. George News). In spring they get much of their water from green plants; in drier times they drink at potholes and springs (NPS).

Second, the comeback. Bighorn had disappeared from Zion by the mid-1900s, after habitat loss, hunting, and diseases carried by domestic livestock. The park and the Utah Division of Wildlife Resources brought 14 sheep back by 1978. The start was rocky, but by 2018 the herd had grown past 500, and biologists now watch for crowding and for contact with domestic sheep and goats, which can spread fatal disease (NPS).

Watching Them Responsibly

• Stay at least 100 feet away. That's Zion's distance for bighorn sheep, deer, condors, and mountain lions (NPS). Use a zoom lens or binoculars.
• Never feed them. Feeding wildlife is prohibited, and so is making any noise to attract an animal, including calling, clicking, or whistling (NPS).
• Pull completely off the road. Use a pullout and drive slowly on the east side; sheep do get hit by cars there (St. George News).
• Stay near the road. Zion's herd tolerates traffic surprisingly well. Trouble starts when people walk out toward the animals, which can push them away from food, water, and shade. If a sheep is staring at you, you're too close; back off (St. George News).

The Short Version

Drive the east side slowly, look up as much as you look ahead, and treat a sighting as a bonus rather than a promise. If one appears, a pullout and a pair of binoculars will give you a better view than walking closer ever would.
