Adventure to occur soon during an upcoming Summer.
There is a popular circuit route including Sisters South, Sisters North and Black Rock Sister. The route can be taken in either direction and includes about a half day of challenging hiking and climbing (Class 3 at most) in a beautiful pristine wilderness setting.
Take Hwy 95 North from Las Vegas. Turn left onto Lee Canyon Road (Hwy 156). Continue on Lee Canyon Road about 16 miles. You’ll continue on Lee Canyon Road past the intersection with Deer Creek Road. In a few miles, just before the turn-around (circle) on Lee Canyon Road take a right toward the Old Mill Picnic Area. There is a fee to park in the Old Mill Picnic Area, but on the other side of Lee Canyon Road just before the turn-around there is a wide area where I have parked free before.
Beginning at the Old Mill Campground, follow the paved road. The paved road will branch off onto an unnamed gravel trail (rocks laid out to mark a border on each side of the trail). Continue on this border-lined trail, then take a right onto a small use trail that branches off to the Northwest up a gully. Follow this use trail up to a saddle which leads to the Sisters South. There’s a short class 2-3 rock section just below the summit.
Follow the ridge from the Sisters South to the Sisters North, dropping down to the right when it becomes too cliffy, steep and exposed. Watch for cairns along the right side of the ridge. Follow the route as it eventually crosses over to the left side of the ridge and descends onto the Western slopes of the Sisters North. Continue on the West side of the ridge up to the summit of the Sisters North.
From the summit of the North Sisters North, head Southwest down a steep avalanche slope to Black Rock Sister.
Follow the steep gully back to the point where you originally parked on or near Lee Canyon Road and the Old Mill Campground.
