Been here a couple of times now and currently camping for the first time. I love this place. The views of the river are second to none and absolutely breathtaking. Lots of history of the area. Out of the way in a good way!
Small state park, so not much is happening this time of year. Campground is closed of course, but the hiking trail is accessible, even though it is pretty icy in spots.
