As pineman said, fishing up Walker Camp prong from the first bridge at the Chimneys trailhead is a good area. If you go just past the tunnel that curls around over itself, there is a gravel pulloff to the left of the road. Just across the road and up a few feet is easy access to the stream. From that point up is some really fun fishing. You'll pass the bridge where one of the WCP tributaries runs in just up stream from there and can fish on up to the pulloff with the parking area that pineman referred to. From the top of the tunnel to that parking lot is several hours of good fishing. I caught one of my biggest specks in that area and the last time I fished it, I caught a bow that was easily 12". Highly recommend it. Easy to get to but I've never run into another fisherman in that stretch.
