Passing through the Lime Belt burn scar southwest out of Conconully, South Fork Salmon Creek Road is a rough forest road through the Okanogan-Wenatchee National Forest. Also called Forest Road 42, it starts nicely graveled but gets rough and rutted near the halfway point just after FR 300. It'll stay rough until it intersects with South Beaver and then becomes a paved road as it continues south to Loup Loup Campground and Highway 20.
Dispersed camping on this road is sparse, with only one or two locations along the whole road, but several offshoots may provide better accommodations. Nearby improved camping can be found at the Loup Loup Campground, a Forest Service campground that charges a nightly fee.
