OverviewSouth Twin at 10,340 ft. is the second highest summit in the Salmon River Mountains of Idaho and sits between White Mountain (10,442 ft.), the highest peak in the range, and North Tiwn (10,196 ft.) another of the highest summits. When viewed from Challis, Idaho South Twin appears to be the highest of the three but this is only because of the angle it is viewed at. It really is only 98 ft. lower than White Mountain though.
The peak is a loose pile of rust colored talus when viewed from the South. When seen from the North it shares the whiteish hue of its neighbor, White Mountain.
historical pictures of the lookout.) The road leading to the lookout is also one of the highest roads in Idaho. Because of the road it is only a class 1 hike. The walk to the top is pleasant and the view from the top is absolutely amazing taking in everything from Mount Borah to the South, to the Bighorn Crags in the North and everything in between. In fact seven major mountain ranges (Pioneer, Boulder, White Cloud, Sawtooth, Salmon River, Beaverhead, Lemhi, and Lost River) are visible from its summit, all of them among Idaho’s highest and wildest.
This is a very narrow road with room enough only to park or turn around at the switchbacks. There is no room for error as the drop-off on the downhill side can be pretty scary.
Depending on your vehicle you may wish to park where the road splits and walk up the road to the summit. If you’ve got a high clearance outfit you could continue up to the summit or at least to the first major switchback and walk the remaining 500 vertical ft. up the road.
Red TapeBe aware that the lookout road is narrow and rough. While is 4WD is not essential it is a good idea. High clearance, though, is a must. Just pray you don't meet someone coming the other way.
Also be advised that the forest on West side of the Twin Peaks and White Mountain burned recently and can be subject to flash floods and other rapidly changing conditions.
Also, as with all wilderness areas, motorized travel is restricted in the Frank Church Wilderness. You shouldn’t need to worry about that though since you’re coming to climb. Remember, pack it in, pack it out.
No permits of any kind are required.
CampingThere are several good camping spots along Bear Creek. There is one established site with a table and fire ring near the cabins where the road splits. If you continue up the Sleeping Deer Road to the pass there is a large area established on the wilderness boundary suitable for camping. This area has several fire rings and a VERY primitive toilet.[img:527011:aligncenter:medium:Amazing sunset from Twin Peaks pass.]
