Summit Trail To Bear Mountain Trail is a 21 mile out and back trail located near Imnaha, OR and is rated as moderate. The trail is primarily used for hiking and is accessible from May until November.
Beautifully scenic area. This trail is in Hells Canyon on the border of OR/ID; I only went for a day, but it was a nice hike. At night it got really windy and you could hear the wind gusts coming through the canyon it was awesome! If you start from the upper ridge, bring a lot of water since its a long hike down to get water from the river.
