The 300 acre McCaslin Mountain Campground borders the beautiful Nicolet National Forest on the western edge of Marinette County in northeastern Wisconsin. Our location is ideal in any season for the outdoor enthusiast. Marinette County boasts the most miles of trout steams of any county in Wisconsin and we are also just a short distance from the newly established Governor Thompson State Park and the Peshtigo River State Forest surrounding Caldron Falls and High Falls Flowage.
