First of all you have to get on a 10 mile dirt road to get to the campground. The road is not too bad for a truck or SUV. May be a little challenging for normal passenger cars but doable.
Both campgrounds are nice and close to the waters edge. However a noisy and busy train track for freight trains run on the other side of the river. It feels and sounds like freight trains will run right thru your tent at all times of the day.
The big plus: its free.
Really nice campground with sites being spread apart and not too close to each other. When the sun sets in June and July the mosquitos will come out. They are quite nasty but an hour after sunset they are gone, having a campfire going helps too. A bundle of firewood is 6 bucks and will be delivered to your site. Vault toilets are very clean and smell fresh.
