This park is part of Portage Lakes State Park. It's located some distance from Portage Lakes State Park. I initially went to Portage Lakes State Park only to find there was a sheet with directions to Nimisila. It was not possible to follow the directions and drive a motorhome. Neither the street address or a geographic location was on the sheet for us Garmin and Tom Tom users. I finally figured out the intersection of Christman and Nimisila Roads. The actual address is 5550 Christman Road. Only 6 sites have electricity. We camped here in a Motorhome.
