Sites are approximately 2 miles from parking and the hike it relatively easy with minimal elevation change. You have a choice between a grassy walk or walking mainly on tar and gravel as part of the Blazing Star Trail. They are also accessible by boat.
There are 4 backpacking sites and they are well-spaced so you each have privacy. #3 and #4 are close enough that you could be in a group together but #1 and #2 are pretty isolated. Each site has a fire pit, picnic table, wood cabinet/fish cleaning table, at least 1 flat spot for a tent, and a nearby porta potty.
Views of the lake are amazing with a variety of birds making appearances. Harvesting season may bring some farm sounds but otherwise, aside from the occasional train, you'll mainly hear the sounds of nature around you.
If you can make the walk carrying everything, including water, on your back, definitely check out one of these sites.
