Elk Creek Road

FS 340 runs from Edwardsburg to Warren and is the second section of a four-road route from Yellow Pine to the Salmon River at Riggins. The road is generally easy to drive, but due to rocks poking above the road surface, moderate ground clearance is needed. Four-wheel drive is unnecessary, but it might be helpful on the occasional steeper sections with loose rock. The road is one lane, mostly gravel, with some turnouts. The major hazards are blind curves, a narrow roadbed, and some rocks.

There are ample places to dry camp and a campground at the South Fork of the Salmon River. There are large stretches where the views are incredible—or would be if there is no smoke in the air. Smoke is a common occurrence during the fire season from July to September. There are also many small, picturesque streams along the road and, for a short section, the South Fork of the Salmon River.

The forest road number changes from FS 340 to FS 337 at Warren Summit and then back to 340, so it is essentially one road with two numbers assigned to it.
