Mountain Lions in Idaho: identification guide and where to start looking
Mountain lions (cougars) roam Idaho's wild country, but they're rarely seen. Look for a large, unspotted cat with a long, black-tipped tail and a small head. Best odds for a glimpse are in the foothills and canyonlands of central and western Idaho, especially around dawn and dusk.

1. What are the key identification markers for mountain lions in Idaho?
Mountain lions are large, unspotted cats with a tawny or grayish coat. The most reliable field mark is the long, thick tail that is roughly one third of the animal's total length and has a black tip. Adults weigh 80 to 200 pounds and stand about 2 to 3 feet at the shoulder. The head is small and rounded with prominent whiskers. For more context on the species, see our/animals/mountain-lionpage.
In Idaho, mountain lions sightings usually improve when you slow down and match your first stop to the most useful ID markers and likely lookalikes. Use thestate wildlife huband theroute guideto narrow your first area, then check access, weather, and distance before you settle in. A short walk with one clear viewing plan often beats covering too much ground, especially when habitat changes fast from open edges to brush, wetlands, timber, shoreline, or neighborhood cover.
2. Which lookalikes are most commonly confused with mountain lions?
Bobcats are smaller (15 to 35 pounds) and have a short, stubby tail with a black tip only on top. Coyotes and domestic dogs have bushy tails that are often carried low, and their face shape is more canine. A mountain lion's tail is uniformly thick and black tipped, making it the best distinguishing feature. Never rely on color alone.
3. Where in Idaho do people most often see mountain lions?
Most sightings come from the rugged canyon country of the Salmon River, Clearwater, and Payette River drainages, plus the foothills around Boise and McCall. Mountain lions favor steep terrain with rock outcrops and dense cover. They are also reported in the/wildlife/idahosection of the state, especially around the Frank Church River of No Return Wilderness.

4. What time of year gives the best chances for a sighting?
Late winter and early spring (February to April) offer the best odds because snow pushes deer (their main prey) to lower elevations and the cats follow. Dawn and dusk are the most active periods year-round. Fresh tracks in snow are the most reliable clue. Summer sightings are rare but possible near water sources at dawn.

5. How do you distinguish mountain lion tracks and signs?
A mountain lion track shows four toe pads and a three lobed main pad with no claw marks (claws are retracted). The track is roundish, about 3 to 4 inches across for adults. Scat is segmented, often covered with dirt, and contains hair and bone fragments. Scratches on trees or mounds of leaves (scrapes) are marking signs.
6. What should you do if you encounter a mountain lion?
Do not run. Make yourself look large by raising your arms or holding a jacket open. Speak firmly and slowly back away while maintaining eye contact. If attacked, fight back with rocks, sticks, or anything available. Report any sighting or encounter to Idaho Fish and Game.

8. Can mountain lions be found in eastern Idaho?
Yes, they occur throughout the state including the eastern ranges like the Teton and Caribou regions. However, habitat is less rugged there, so densities are generally lower. The best areas remain the central and western breaks.
9. Are mountain lion sightings increasing in Idaho?
Human population expansion into foothill areas and better camera technology have led to more reports. Idaho Fish and Game estimates a stable population of around 2,000 to 3,000 lions. Sightings are still rare events.
