This was a nice little park and campground area with a good hiking trail. The park has multiple playgrounds that look cool (didn't have my son with me). The lock itself is no longer functioning, but makes a cool little overlook to the river and apparently a good fishing spot.
The campground had spots right along the water, and some back in the woods. They all looked nice.
Really, we were here for the hiking trail. The trail isn't super challenging, mostly smooth paths with slight inclines here and there. The path is wide and easy enough to follow. The map they provide is not very good, and there are very few markings along the path, so it wouldn't be hard to get turned around, but since it's mostly a big circle, you shouldn't be able to get lost. There's also an overlook point that has some nice views and a bench and small picnic table.
One thing we really liked is that they had the roots that stuck up along the path marked with bright orange paint. Helped make sure you didn't trip or get your foot caught, which was cool.
