Osprey Falls Trail
What to Expect
Safety Advisory
This is serious grizzly bear country. The meadows along the service road and the canyon bottom are both high-activity areas. Carry bear spray accessible on your chest or hip, make noise consistently, and hike in a group if possible.
The canyon descent is steep, loose, and fully exposed to the sun. The climb back out gains 700 feet in less than a mile — allow twice as long for the return and carry more water than you think you need.

Pro Tips
Start early from the Bunsen Peak trailhead near Mammoth — the three-mile road walk is exposed and heats up fast by mid-morning. You can also bike the service road section to cut the flat approach time in half, then lock up at the Osprey Falls junction.
Trekking poles are borderline essential for the canyon descent and especially the climb back out. The switchbacks are loose and steep enough that a slip on tired legs is a real possibility.
The base of the falls has a rocky alcove on the left side where spray catches the light perfectly in the late morning. Bring a lens cloth — the mist is relentless and will fog everything you own.
