4) Go straight through stop sign to Shasta Dam, cross the dam.
Matheson Access: I-5 to Redding, 299 West 2 miles to Iron Mtn Road, turn right, go north 6 miles, right on Matheson Road. "Copley Mountain" staging area is on the right (GPS coords: N40.39.536 122.28.136W). You can continue on Coran Road a few miles to get to the main camping/staging area under the dam. Note that this is a roughly graded road. 4x4s and 2x4s with high clearance are ok, but it is probably too rough for most RVs and travel trailers.
