Chimney Rock to Junction City — Trinity Alps Backcountry High Road

Before the gold rush played out, the Trinity Alps were crawling with miners punching roads into granite ridges that most modern drivers have forgotten exist. This route climbs from Chimney Rock Road off Highway 299 near Douglas City, gains the ridge above the South Fork Trinity, and works northwest through old mining territory toward Junction City — passing the ruins of the La Grange Dredge tailings and dropping through Canyon Creek Road with views into the wilderness area that stop you cold. The road surface alternates between compacted gravel, embedded granite slabs, and loose shale sidehills where you earn every mile.

Expect genuine high-clearance work — a stock SUV with factory skids will get beat up, and an RTT rig with long overhangs will have a hard day on the switchbacks above the South Fork. Best run June through early October; snow lingers on the upper sections well into May. No permits required on the USFS sections, but some lower segments cross private mining claims — stay on the road. Fuel in Weaverville before you leave. Cell service is effectively zero. What you get out of it is one of the least-visited corridors in the California mountains, with dispersed camping on national forest land and zero crowds.
