I've been on an RV road trip to states I have not yet visited in the past. Wisconsin is one of them. Copper Falls State Park had it all. Multiple beautiful hiking trails, all by different beautiful waterfalls, Copper Falls, Brownstone Falls on the Bad River. 

It was a really nice campsite in the forest. There is not much to say about it, just like other campgrounds in the area, in the forest. The trail to the falls is an easy walk from the campground.

Please note that you need to make a reservation when you arrive online or via phone. There is no walk-in. You also have to pay the daily State Park fee which is higher if you have an out of state plate; even for camping. If you spend more than 4 nights in State Parks it's worth buying the yearly pass. If you are only traveling through and lucky enough to find an opening, it can be a bit costly. It cost me over $100 for two nights with electric hookup.

The cell signal was pretty bad down in the campground, it was way better up by the entrance area. There is a lake too with another hiking trail to a different waterfall.
