Didn't do the whole loop but covered a few of the trails by the river and lake. Great location, well-looked after trails. And because of the camp sites, a few handy stops for water too.

I walked the prairie and wet land trails which were beautiful and serene. I imagine that if you're a bird watcher this would be a great spot since there seem to so many.

I can't speak to the trails by the river but the prairie and wet land trails (which is the majority of the park) made for a nice few hours. The paths are marked and well kept for grass and dirt trails.
