Originally designated the Ma-na-to (Manitoo) River, translated “Stooping Spirit River,” by native Ojibwe peoples, the name was mistaken by early settlers to mean “Devils River.” This mistranslation stuck and today Devils River is the name of the 16-mile-long waterway that flows into the West Twin River, which in turn empties into Lake Michigan. Visitors to the river can enjoy some outdoor time at the Devils River Campground, while exploring some of the historical sites around the area, including an old mill and the remains of an old stone bridge. The river is also a popular fishing hole for bullhead catfish, rock bass, northern pike, and brown and rainbow trout.  

Located approximately 30 minutes southeast of Green Bay, the Devils River Campground offers 130 parklike campsites situated among open, grassy clearings (i.e., minimal privacy) surrounded by shady trees. Sites can accommodate both tent and RV campers (max 50 feet), and are equipped with picnic tables, fire rings, and water and electrical hookups. The central comfort station provides flush toilets, showers and laundry facilities; a dump station is located nearby. The campground also features a large swimming pond, a playground, and access to the Devils River State Trail for exploring the river, wetlands, and local prairies. Dogs are welcome at this campground. Campsite rates are $32–$38/night.

Situated right in the campground is the historic Rock Mill. Constructed in 1847 by Pliney Pierce, the mill first operated as a sawmill, then as a gristmill, for nearly a century. The remarkably well-preserved building was added to the National Register of Historic Places in 1982. The mill is not open for public touring, but can be viewed from outside. Just a mile south of the campground, visitors can explore some natural history at Cherney Maribel Caves Park. The park has many caves, crevices, and cliffs that can be explored by the public. A few caves can only be seen by joining a seasonal cave tour. The park also has picnic areas, a playground, and trails for hiking, biking, and skiing.
