Alley Trail - Hiking trail near Boise, Idaho, United States - Description

As this trail leaves the ridge between Granite Basin and Lightning Creek it traverses an old burn, then descends through stands of lodgepole pine before crossing Lightning Creek. After crossing the creek the trail ascends a long steep ridge where it passes a small pond and intersects the Onion Valley Trail. A large portion of Lightning Creek can be seen from this trail. High spring flows may make it impossible to cross upper Lightning Creek, so plan carefully.

Heading east on the Banks-Lowman Highway, turn left on NF- 668 at the Garden Valley High School. Head north for approximately 11.2 miles to the junction with NF-668B. Turn right on 668B and travel approximately 3.1 miles to the end of the road. From the end of the road go east on the Airline Trail for approximately 0.4 miles to the Alley trailhead. High clearance vehicles will be required to reach the trailhead.
