This is the place to experience some of the best spring Coho and steelhead fishing possible on Lake Michigan. Winthrop Harbor is located at the Wisconsin/Illinois border. You will be catching limits of Coho Salmon with a mix of some Brown Trout, Rainbow Trout, and King Salmon. You will be very happy to make the trip. We are stationed here from April 20 through June 15. Book your dates early, this time of year fills fast!!
