Nearest Paved Roads: ID-21 (from Boise via Edna Creek this drive is about 2.5 hrs)
Nearest Dirt Roads / Conditions: China Basin/ Queens River Road (decent- usually passable without 4WD), Middle Fork of Boise River (Good), Swanholm Peak Road (Good), North Fork Boise River Road (Good), Edna Creek Road (Good)
Approach Trails / Conditions: The Queens River trail is a good single track trail. The China Basin trail toward Atlanta is rough in the river valley section and gets better the higher up it climbs.
Main Route: Follow the Queens River Trail for 2.7 miles to the right turn (south) onto the China Basin / Joe Daly trail. This junction is marked with a small "Atlanta" sign. Cross the Queens River and climb the switchbacks to an initial high point, then drop into China Basin and climb to the high point of this trail at 1.8 miles from the previous junction. The trail from here drops down south to Atlanta, but leave the trail and follow the side ridge to a point between Point 8404 and Point 8826. This section is the most rugged and loose of this climb. From the saddle climb over Points 8826 and 9298. The true summit is Point 9363. Retrace your route, or follow the ridge onto Blizzard Mountain for a great ridge traverse.
