Not overnight. You can at Spruce Run, though. Round Valley camping is wilderness camping with the sites only reachable by boat or hiking.
Nope
Yes, to park, but at the campers parking. I believe you can't at the section for boat/kayak launch.
To my knowledge, no.
I didn't see any but probably if You call the park They will give You the details, they are open now for fishing season.
