Grizzly Peak Trail is a 9.9 mile lightly trafficked out and back trail located near Idanha, Oregon that features a lake and is rated as difficult. The trail is primarily used for hiking and is accessible from July until October.
Trail is rough in spots, and large log has moved part of it. The main thing is take your time. Once you are near the top, the view is awesome! I have been there summer and fall, once in winter but clouds were too low to see much. Nice trail, a bit steep.
