Have fun y'all.
Some notes from my last time there:
Water available ONLY at the water tanks. At least when I was there. There was one stream between C & D, but even I wouldn't drink from it as it quite shortly feeds into a large stagnant pond, with some old beaver sign around it.
More than ample hang sites at the listed campsites.
Some Very good hiking, I only found one view (between C & D) but worth the walk.
Get a map, READ IT! There are some neat historical landmarks listed & Marked. The lake mentioned above is near the site of a former mining camp.
At D, the Privy is near the water tank, the campsites are behind it. There is a fairly nice gathering area about a 1/4 mile walk from the privy. When I was there: Fire ring, sitting logs, minimal hang sites AT the fire pit.
IF you choose to walk the service road, be alert, the water truck driver,,,,, drives "quickly"! Also: DO NOT CAMP ON THE SERVICE ROAD OR THE TURN AROUND. He was there in daylight when I was there at C, but it was Very early, I think around 8:00 AM. Not great hanging, but at C it "Could" be done.
Go Right out of the parking lot for the old forge (Immediately cross the bridge back towards the trailhead) & about 2 - 4 miles on your right is a lake with a swimming beach. All of us went for a swim after the last hangout, had a great time cooling off!!
