We stayed here one quick night on a trip driving the Trans Wisconsin ATV Trail. This is one of 2 campgrounds in the Flambeau River State Forest. It was fairly rustic and remote, but had clean vault toilets, hand pump for water, and a nicely wooded sites. We walked to the lake at dusk and enjoyed great views. There is a boat launch, and also a path to a small beach with a swim area.   Not a destination for us, but a great stop.

Pro Tip:  We found wood close by at the Flambeau Forest Inn, with a pick up and paybox outside. Nice to be able to get wood without needing to go inside.
