Signal Mountain Trail
What to Expect
Safety Advisory
Bear country is not a suggestion here — grizzlies and black bears are active on Signal Mountain, especially in late summer when berries ripen. Carry bear spray and make noise on the forested sections where sightlines are short.
The summit is exposed and the Tetons generate their own weather. Afternoon thunderstorms roll in fast from July through September — if you see clouds building over the peaks, start heading down.

Pro Tips
Start early — not just for cooler temps, but because the morning light on the Tetons from this angle is the best you'll find without a backcountry permit. By noon the range goes flat and hazy.
The summit is also accessible by car via Signal Mountain Road, so time your hike to arrive before the road traffic picks up around 10 AM if you want the summit clearing to yourself.
Bring a telephoto lens or binoculars — from the summit you can pick out the Cathedral Group in stunning detail, and in fall you might spot moose browsing the willows along the Snake River oxbow far below.
