The trail to the pioneer cemetery is ok for dogs. The trail to the falls is not but it seems like there's always someone who can't follow instructions. If you stay in a cabin they're not allowed inside.
Campground is dog friendly. There are a couple trails you can take your dog on, but not the loop that goes by the falls. There is even a beach that you can walk to with your dog. Ask the ranger for specifics when you get there.
Not really, dogs aren't allowed on any of the trails.
