The primary summer access is via paved road from Cascade to Landmark. From Landmark, the single-lane, unpaved Johnson Creek road runs north to Yellow Pine, and from there, the Yellow Pine-Stibnite road runs east to the historic mining town of Stibnite, Idaho. Using this route, the trip from Cascade to Stibnite is about 121km long.
An alternate, low elevation year round access runs from Cascade to Warm Lake and then downstream along the South Fork of the Salmon River to the confluence of the South Fork and the East Fork of the South Fork Salmon River (EFSF), then upstream along the EFSF to Yellow Pine and onto Stibnite. Using the alternate route, the trip from Cascade to Stibnite is about 137km long. The road from Cascade to Yellow Pine is an open and maintained all season.
A second summer route starts at McCall, Idaho, and passes over Lick Creek Summit, then down the Secesh River drainage to its confluence with the South Fork of the Salmon River and up to the confluence of the South Fork and EFSF. Using this second alternate route, the trip from McCall to Stibnite is about 100km long. Improved, gravel airstrips are located at Stibnite and on Johnson Creek, about four miles south of the town of Yellow Pine.
