Solid hiking trail and good campsites. The campsites have adequate space and decent amenities. The biggest issue however was ticks. Been an outdoor person my whole life and more ticks than I’ve ever seen before. Pulling 10 or more off an hour…
About 22 sites, or so, right on a bend of the Brule River. a Beautiful trout stream with canoeing and kayaking popular sports. Rentals about 1 mi. away in Brule with reasonable prices. Fishing off the pier. Two "remote" sites RIGHT ON THE RIVER. Sites well cared for. DNR about 1/4 mi. away. It's one of my favorite spots up north. Not a lot of entertainment for small children--i.e. no playground, for instance, although the fish hatchery is 1/2 mi. away. If they like fishing, it's great though. The river's cold, so small kids would not like to swim there. L. Nebagamon is about 5 mi. away though.
Stayed in June, the campground was small but luckily we were there in the middle of the week so it wasn't too busy. The campsites are pretty close together so of it's busy, your experience may be very different.
We did a little hiking. Trails are good and well marked. Looked like folks were enjoying the fishing too.
