Copper Falls State Park sits where ancient lava flows meet the Bad River and Tyler Forks River gorges, about 1,247 feet above sea level near Mellen. The park's 63 campsites (tent, RV, and cabin options) put you within walking distance of two major waterfalls and roughly 17 miles of trails. Facilities include flush toilets, showers, and a small beach on Loon Lake.
Developed state-park campground with tent and RV-capable sites, plus cabins (including at least one ADA/accessible cabin reported). Sites are wooded and spacious.
Historical Significance
The Civilian Conservation Corps built log structures here in the 1930s. A few of those buildings are still standing and in use.Weather and SeasonsFall is the standout season. Daytime highs run 45–60°F, nights drop to 30–40°F, and the hardwood canopy turns orange and red. Water levels are usually moderate, so the falls look dramatic without being dangerously swollen. Mosquitoes die off. Weekends during peak color get crowded; midweek is quieter. Summer is warm and green, but reviews consistently mention heavy mosquito and biting insect activity near the river and low-lying areas. Bring repellent. The observation tower's views can be blocked by leaf cover in summer. Showers close in the off-season, so confirm facilities if you're visiting in late fall or early spring.
Natural Features and SceneryCopper Falls and Brownstone Falls plunge over volcanic bedrock into narrow gorges carved by the Bad River. Boardwalk overlooks hang above the water, close enough to feel the spray on humid days. The forest is a mix of northern hardwoods and conifers. Maple, birch, hemlock. That shift as you move between the gorge rim and flatter ground near Loon Lake. The Doughboys Nature Trail is the main loop through this terrain. When the river's running high, the falls are loud. When it's not, you can hear smaller cascades upstream. Loon Lake has a sandy beach that's calm and shallow, a different world from the rocky gorges a quarter-mile away.
Geological RegionAncient lava flows and volcanic rock canyons along the Bad River and Tyler Forks River; deep gorges and bedrock waterfalls.
Scenic ViewsOverlooks and boardwalks into the gorge with waterfall views; an observation tower is present but reviewers note views can be blocked by tree canopy in summer.
